Mold Assessors and Remediators Frequently Asked Questions

Transition from DSHS to TDLR

1. When did the transfer happen?

The Texas Department of Licensing and Regulation (TDLR) assumed all activities relating to the Mold Assessors and Remediators program including licenses and renewals, customer service and enforcement on November 1, 2017.

2. Now that the transfer is complete, will I need to get a new license issued by TDLR?

No. The license you have now, issued by the Texas Department of State Health Services (DSHS), remains valid until its expiration date. When you renew, you will receive a TDLR license.

3. Have the rules changed?

Yes, TDLR adopted rules for all of the transferred programs. Most of the newly adopted rules are very similar, but some changes have been made. The TDLR health profession rules became effective on November 1, 2017.

4. What is going to happen with open complaints and cases?

If you filed a complaint with DSHS or had a complaint filed against your license and it was not resolved by the transfer date, TDLR assumed responsibility for the case. You should have already received notification by mail that your complaint was transferred to TDLR.

5. How do I stay informed about changes impacting me?

You have several options to stay connected:

  • Email updates - Sign up for email updates to receive notices about rules, the law, fees, examination requirements, meetings and more. Email updates are the best way for you to stay informed.
  • Meetings - TDLR’s advisory board and Commission meetings are available to watch online live or later at your convenience.
  • Facebook and Twitter - TDLR has a Facebook page and Twitter account dedicated to TDLR Health Professions.

6. Why was my license expiration date extended? Will I have the same expiration date in the future?

To ease the transition, DSHS extended the expiration date by two months for licenses previously set to expire in September, and October, and November 2017. For example, if your original expiration date was September 30, your new expiration date is November 30. If your license was extended, you will continue to renew your license in the new expiration month in the future. Licenses in counties affected by Hurricane Harvey were also extended by DSHS.

7. Will I have to renew on a different schedule?

You will renew on the same schedule unless your license expired in August, September or October 2016. Licenses expiring in those months were extended for two months to ease the transition from DSHS to TDLR. In addition, licenses in counties affected by Hurricane Harvey were also extended by DSHS. If your license was extended, you will now renew in your new expiration month for future renewals. Your license expiration date will not return to your original expiration month.

8. Why were licensing programs transferred from DSHS to TDLR?

The transfer is the result of a change to Texas law. In 2015, the Texas Legislature passed Senate Bill 202, which authorized the transfer of thirteen licensing programs from the DSHS to TDLR.

2. Why do I have to pay a late fee?

Licensees who renew late are required to pay a late fee. If the license is expired for 1-90 days the fee is 1 ½ times the normally required renewal fee. If the license is expired for more than 90 days the fee is two (2) times the normally required renewal fee.

Criminal History

1. Why is TDLR asking me about my criminal history? The DSHS application and renewal forms did not ask about criminal history.

Convictions for some criminal offenses might disqualify a person from holding a license in a program administered by TDLR. TDLR is asking this question in order to determine whether you are eligible to receive or renew a license. TDLR also completes criminal history background checks on all applicants for licenses in other programs.

Also, TDLR may determine that a person is not eligible for a license based on the person's criminal history or other information that indicates that the person lacks the honesty, trustworthiness, and integrity to hold a license issued by the department.

If you are not yet licensed, and you are concerned that your criminal history may prevent you from becoming licensed, you may wish to request a Criminal History Evaluation Letter.

Licensing and Registration

1. Since there is no state exam required for a company license, when can I submit my licensing application for my company?

Company applications may be submitted at any time. Please review the application for eligibility requirements.

2. The rules state “a person licensed under this chapter must maintain an office in Texas.” Who must maintain an office in Texas?

This requirement regarding maintaining an office with a street address in Texas only applies to "licensees,” i.e., Mold Assessment Technicians, Mold Assessment Consultants, Mold Assessment Companies, Mold Remediation Contractors, Mold Remediation Companies, and Mold Analysis Laboratories. Individual licensees employed by a licensed mold company with an office in Texas are considered to satisfy this requirement.  For example, mold assessment technicians or consultants working for a licensed mold assessment company that has an office in Texas would not have to have their own office in Texas.

Please note that the office in Texas requirement does not apply to Training Providers, because they are seeking "accreditation." Neither does it apply to Mold Remediation Workers, because they are seeking "registration."

3. Can an individual or company get both a mold assessment license and a mold remediation license?

Yes, if you meet all qualifications and requirements for each license. However, you are not allowed to conduct both mold assessment and mold remediation activities on the same project, unless you are employed by a school district and working on a project for that school district.

4. If mold remediation workers get registered while employed by a company, then want to work for a different contractor or company, are their registrations still in effect?

Yes, the registration belongs to the worker, not the company.

5. Do I still apply to take the examination before I submit my application for licensure?

No.  Applicants for mold assessment technician, mold assessment consultant and mold remediation contractor must first submit an application for licensure.  This can be done by submitting a paper application or an online application.  The application fee and all additional documentation to show proof of required training, insurance, education and experience must also be submitted.  Once your application is approved by TDLR, you will receive notice from TDLR’s exam vendor, PSI, that you are eligible to schedule and take your required examination. PSI will send your examination score to TDLR.  Once TDLR receives notice that you have passed your exam, and all other requirements have been met, the license will be issued.

6. How do I get a temporary mold remediation worker registration?

In order to receive a temporary mold remediation worker registration, you must submit your mold remediation worker application online. The receipt from the online application will serve as your temporary registration. The receipt must be printed, and is required to be in your possession or on the job-site when performing mold-related activities.

7. How long is the temporary mold remediation worker registration valid?

The temporary mold remediation worker registration is valid for 21 days. You must stop performing mold remediation services, if you have not received your mold remediation worker registration before the temporary registration expires.

8. Can I renew my temporary mold remediation worker registration?

No, the temporary registration may not be renewed.


1. Who administers the Mold Technician, Consultant, and Contractor Examinations?

The exams are administered by TDLR’s third-party vendor, PSI.

2. How will I be notified when I am eligible to take the exam?

The passing score is 70% or higher.

16. If I fail the exam, how soon can I schedule a retake?

You may schedule a retake with PSI, within 24-48 hours of your failed exam.

17. How many times may I retake the exam?

Your license application is valid for one year and you may retake the exam until your application expires. When your application expires, you will need to submit a new application before you can retake the exam.

Continuing Education

1. How many hours of continuing education are required for the renewal of Mold Assessors and Remediators?

The following licensees are required to complete a mold remediation worker continuing education course with the required continuing education hours provided by an accredited mold training provider, a licensed mold remediation contractor or a licensed mold remediation company:

  • (1) mold assessment technician license – 8 hours
  • (2) mold assessment consultant license – 8 hours
  • (3) mold remediation contractor license – 8 hours
  • (4) mold remediation worker registration – 4 hours

2. Do I need to provide my continuing education certificates of completion when I renew my license?

No, please do not include your certificates of completion with the renewal of your license. The Department shall select a random sample of license holders for each renewal month. If selected for an audit, the licensee will be notified when they receive their renewal notice. The licensee will be required to submit copies of certificates, transcripts or other documentation to verify the licensee’s attendance, participation and completion of continuing education requirements. Licenses will not be renewed until continuing education requirements have been met.

3. Am I required to maintain a record of my continuing education experiences or certificates?

Yes, you are responsible for maintaining a record of your continuing education experiences or certificates. These records will be required if you are selected for audit. If you are selected for audit, then you will be notified and records will be required to be submitted to the department.

Training Providers and Courses

1. How do I obtain a Mold Training Provider Accreditation?

You submit the Mold Training Provider Accreditation application along with the required $750 application fee and include all required documentation.

2. Do I have to obtain approval for the courses I want to offer if I hold a Mold Training Provider Accreditation?

Yes, you must obtain approval prior to offering any training courses.

3. How do I obtain approval for the training courses?

You submit the Mold Training Course Approval application along with the required $100 application fee for each course and include all required documentation.

Homeowner/Building Owner Exemption

1. Under the Texas mold rules, a homeowner or building owner can, in some circumstances, do his or her own remediation under the exemptions in Occup. Code §1958.102 and 16 TAC § 78.30 (b)-(d) (minimum area, residential property and facility exemptions).  If a homeowner or building owner does his or her own mold remediation without using a licensed mold consultant to develop a mold remediation protocol, and then asks a consultant to conduct a clearance test/inspection, can the consultant conduct clearance?

No.  A consultant who has not prepared a mold remediation protocol in advance of a remediation project cannot declare that the project has achieved clearance. In order to determine if a project has achieved clearance, the consultant must conduct a post-remediation assessment.

Note:   A licensed consultant, who had no role in preparing a pre-remediation protocol, may, however, conduct a post-remediation inspection and sign/deliver a Certificate of Mold Damage Remediation (Department of Insurance Form MDR-1) certifying that he or she has inspected the property and determined that it “does not contain evidence of mold damage.”  The bottom section of the form is for this purpose.  [Insurance Code § 544.303(a)(4)(B).]

Minimum Area Exemption

1. Is a licensed Mold Remediation Contractor (MRC) exempt from all the mold rules if hired for a project where the mold contamination affects a total surface area of less than 25 contiguous square feet of visible mold?

No.  The exemption in §1958.102(a) or (c) only applies to persons who are not licensed to conduct mold remediation, and was meant to allow small projects to be handled more simply and economically.  A licensed MRC performing a small mold remediation project (less than 25 contiguous square feet) is not exempt from the law and rules.  Regardless of the size of the area affected by mold contamination, if a licensed MRC is hired by the consumer, the MRC must comply with the requirements in the law and rules, including the development of a work plan that follows a protocol developed by a licensed Mold Assessment Consultant (MAC). The MRC does not, however, have to submit a notification for the project.

Real Estate Inspectors

1. Is a real estate inspector licensed in Texas required to have a Texas mold license to collect air or visible spore samples to determine the presence of mold?   Must the inspector send the samples to a TDLR-licensed lab?

Yes, this activity is considered “mold assessment”. A real estate inspector must be licensed as a mold assessment technician or consultant to collect air or visible spore samples to determine the presence of mold.  The licensed mold assessor must send the samples to a licensed lab for analysis.  A real estate inspector does not need a mold license to visually observe and note the presence of mold.

Homebuilder Construction and Improvement Exemption

1. Is all mold assessment/remediation done on a one- or two-family home under the homebuilder’s warranty exempt from the mold rules even if the builder contracts out the work?

Yes, all mold assessment/remediation done by the builder under a home builder’s warranty either at the time of construction or later at the time of repair is exempt and may be done without a license (see §1958.102(d)).  The exemption applies whether the mold assessment/remediation is done by the individual builder, by the builder’s employee or by a subcontractor. However, if the person doing the  work is licensed to perform mold assessment or remediation, the rules do apply.

After initial construction is complete, mold assessment/remediation may be done by the unlicensed builder only if done at the same time as repair work. 

2. If a builder hires a licensed mold remediator, to whom does the remediator provide a Consumer Mold Information Sheet (CMIS)?  To whom does the remediator provide the certificate of mold damage remediation (CMDR)?

The law and rules require the remediator (or other licensee overseeing a project) to provide the CMIS to the client who hired the remediator (in this case, the builder), and to the property owner if different, prior to the initiation of any mold related activity. The remediator must also provide the CMDR to the property owner, even if hired by the builder.

3. If a builder, the builder’s employees, or subcontractors conduct remediation work under the homebuilder construction and improvement exemption, can the unlicensed workers give the homeowner a CMDR?

No.  Only a licensed remediator is authorized to give a CMDR. A person who uses unlicensed workers for mold remediation cannot obtain a CMDR because an unlicensed person is not authorized to give a CMDR.

4. If the homeowner cannot obtain a CMDR because the mold work was performed under the construction and improvement exemption, can the homeowner have an inspection done by an independent assessor or adjuster to determine there is no evidence of mold damage?

Yes, under the Insurance Code, a homeowner who is not eligible for a CMDR due to the work being done by unlicensed professionals may have an inspection done by an independent mold assessor or adjustor who is licensed to perform mold assessment. Therefore, a person licensed under the mold rules as a Mold Assessment Consultant may fill in the “Mold Assessment Consultant or Adjustor License Holder Certification” portion of the CMDR/MDR-1 form developed by the Texas Department of Insurance. Such a certification may be presented to an insurer who may not make an adverse underwriting decision regarding a residential property insurance policy based on previous mold damage if the requirements of the statute and related rules are met. See Insurance Code, §544.303(a)(4)(B).

5. Where do I find the "Certificate of Mold Damage Remediation?"

The Certificate of Mold Damage Remediation is available on the Texas Department of Insurance website.

Consumer Mold Information Sheet

Where do I find the Consumer Mold Information Sheet?

Download the Consumer Mold Information Sheet. Licensed mold assessors and remediators are required to provide a copy of the Consumer Mold Information Sheet to each client and to the property owner, if not the same person, before any mold-related activity begins. This requirement does not apply to mold analysis laboratories or training providers.

Lead Based Paint

1. Does the federal rule that addresses lead-based paint hazards impact Mold Remediators in Texas?

Yes. Mold Remediation Contractors and Mold Remediation Companies in Texas should be aware of a U.S. Environmental Protection Agency (EPA) rule, which may impact some of their work. As of April 22, 2010, this federal rule – the RENOVATION, REPAIR & PAINTING (RRP) PROGRAM RULE – aims to prevent cases of lead poisoning in children by requiring certain safety measures for renovation projects that may disturb lead-based paint in homes and child-occupied facilities built prior to 1978. The RRP Program Rule covers buildings such as houses, apartments, condominiums, child care facilities, kindergartens, and schools.

A consequence of the rule is that licensed Mold Remediation Contractors and Mold Remediation Companies who conduct remediation projects in such buildings may also be required to follow the EPA RRP Program Rule and hold certifications as a “Renovator” and “Renovation Firm” if any existing paint is disturbed in a pre-1978 constructed home or child-occupied facility. The “Renovator” certification is valid for five years and is issued by the training provider who provided your eight hour RRP course. The “Renovation Firm” certification, also valid for five years, is issued by EPA in the state of Texas.

1. When is a Mold Remediation Notification required?

A Mold Remediation Notification is required when mold contamination affects a total surface area of 25 contiguous square feet or more and mold remediation will be conducted.
Mold remediation is defined as the removal, cleaning, sanitizing, demolition, or other treatment, including preventive activities, of mold or mold-contaminated matter that was not purposely grown at a location. Preventive activities include those intended to prevent future mold contamination of a remediated area, including applying biocides or anti-microbial compounds.

2. When is an Amendment to a Mold Remediation Notification required?

An Amendment is required when the start-date of a project changes, when the stop-date of a project changes by more than one work day, and/or when the work schedule changes, including either the days or times that work will be performed.

An Amendment is also required if the responsible person (the Mold Remediation Contractor) or the Mold Assessment Consultant changes, or if a Mold Remediation Company or Mold Analysis Laboratory are added to a project.

If a Mold Remediation Company or a Mold Remediation Contractor submits a Notification, and then does not complete the project, the Notification should be amended to list a new stop-date.  The Mold Remediation Company or a Mold Remediation Contractor that will complete the project will need to submit a new Notification for the work required to complete the project.

3. What are the required timelines for submitting an Amendment?

The timeline varies based on the type of change being submitted.

  • Start-date change to later date - as soon as possible but before the start-date on the most recent notice.
  • Start-date change to earlier date - at least five calendar days before the start-date unless an Emergency Notification has been submitted.
  • Schedule changes including work-hour changes - no less than one calendar day before the most recent stop-date or the new stop-date, whichever comes first.
  • Withdrawal of licensed mold remediation contractor or licensed mold remediation company from association with a mold remediation project – five calendar days.
  • Addition of licensed mold remediation company to association with a mold remediation project – one calendar day.

4. When should a Mold Remediation Notification be cancelled?

  • If a Mold Remediation Company or a Mold Remediation Contractor submits a Notification, and then does not begin the project, the Notification should be cancelled.
  • All other changes should be submitted as an Amendment.
  • If a Mold Remediation Company or a Mold Remediation Contractor submits a Notification, and then does not complete the project, the Notification should not be cancelled. Instead, the Notification should be amended to list a new stop-date.  The Mold Remediation Company or a Mold Remediation Contractor that will complete the project will need to submit a new Notification for the work required to complete the project.

5. What is the required timeline for submitting a Cancellation?

The Cancellation should be submitted as soon as possible but before the start-date on the most recent notice.

6. What is the required timeline for submitting an Emergency Notification?

An Emergency Notification should be submitted as soon as practicable but not later than the following working day after the licensee identifies the emergency.

7. What is the fee to file a Mold Remediation Notification? The fee to file a notification for a residential or a commercial project is $25. However, for the month of November 2017 (November 1-30, 2017), you can file a notification without a fee. Starting December 1, the $25 fee is due at the time the notification is filed. There is no fee to amend or cancel a notification.

8. How do I file a Mold Remediation Notification?

To file, amend or cancel a mold remediation notice, use TDLR's Mold Remediation Notification System.

9. How do I amend or cancel a mold remediation notification that I filed with DSHS before November 1, 2017?

If you filed a notification with DSHS and need to amend or cancel the notification after November 1, 2017 contact TDLR at or

10. We are going to do a mold remediation project that involves remediating several rooms in a building, but we are going to do them in stages or phasing, i.e. remediate room 1, obtain clearance on room 1, then remediate room 2 and obtain clearance on room 2, etc. until all the rooms are remediated.  Do we need to send a notification for each room that will be remediated or can we send one notification that includes all the rooms being remediated on this project?

If the mold remediation project is for one client in one building, and the entire scope of the project, including each phase, is included in the protocol and work plan, then you may submit one online notification form if you provide the specific location and the start-dates and stop-dates for each phase of the project on the notification form.  Any schedule changes (start/stop dates and/or times) as the project progresses, including schedule changes of the phases, must be stated in an amended online notification.

Mold in Rental Housing

This information is provided by TDLR to assist tenants in addressing mold problems in their rental units.

1. Can TDLR come to my home to check for mold?

No. TDLR does not inspect or test homes for mold problems, and cannot make a landlord or property owner clean up mold that might be present in a home. The TDLR rules do not relate to the presence of mold in buildings.

2. Can TDLR require a landlord or someone else to clean up mold?

No. TDLR does not have the authority to require a landlord or someone else to clean up mold.

3. What does TDLR do about mold?

TDLR regulates and licenses persons and companies who inspect and test for mold in buildings (mold assessment), and those who clean up and remove mold (mold remediation). TDLR rules require contractors doing these types of activities to be properly licensed by the state and to follow minimum work practices (provided they are not exempt). If a renter believes non-licensed persons are conducting mold assessment or remediation activities and are not exempted from regulation, the renter may file a complaint with TDLR. Please note that in most instances, areas of visible mold of less than 25 contiguous square feet can be cleaned up by people who are not licensed. Also, there are certain exemptions that apply for buildings containing less than 10 rental units, including houses.

4. What is mold and what causes it?

Mold is a type of fungus that is present in our natural environment. Mold spores, which are tiny microscopic ‘seeds,’ can be found everywhere, including inside homes, and are a part of the general dust found in homes. These spores can start growing on building materials and furnishings if they get wet or stay moist. Mold growth should not be allowed in our homes. Eventually, the mold will damage what it is growing on, which may include both the building and the renter’s personal belongings. The key to preventing mold growth is to prevent moisture problems and quickly fix and dry any water leaks or spills that might occur.

5. What is the difference between mold and mildew?

Mildew is a type of mold or fungus. A lot of people use this name to describe small black spots of fungus that can start to grow on damp surfaces. If mildew appears, that means there is a moisture problem.

6. Should I have my home tested for mold if I suspect mold?

Generally, it is not necessary to identify the species of mold growing in a residence, and the Centers for Disease Control (CDC) does not recommend routine sampling for molds. Since the susceptibility of individuals can vary greatly either because of the amount or type of mold, sampling and culturing are not reliable in determining your health risk. Also, standards for judging what is an acceptable, tolerable, or normal quantity of mold have not been established. If you do decide to pay for environmental sampling for molds, before the work starts, you should ask a licensed consultant to establish criteria for interpreting the test results. Consultants should tell you in advance what they will do or what recommendations they will make based on the sampling results. The results of samples taken in your unique situation cannot be interpreted without physical inspection of the contaminated area or without considering the building’s characteristics and the factors that led to the present condition. If you hire a licensed mold assessor to help document your mold problem, any individual or company who provides this service in Texas must be licensed as a Mold Assessor (Mold Assessment Technician, Consultant, or Company) by TDLR. Please note that a mold assessor must provide a copy of a Consumer Mold Information Sheet to the client and to the property owner prior to providing any services.

7. What are the health concerns about mold?

Health effects from exposure to mold can vary greatly depending on the person, and the amount of mold in the home. Symptoms that may occur include coughing, wheezing, runny nose and sore throat. People with asthma or mold allergies may notice their asthma or allergy symptoms worsen. Individuals with a severely weakened immune system who are exposed to moldy environments are at risk of developing serious fungal respiratory infections. TDLR recommends that people consult a health care provider if they are concerned about the effects of a moldy environment on their health. U.S. Centers for Disease Control (CDC) mold information

8. What can I do as a tenant to prevent mold?

Here are some tips to prevent mold:

  • Use exhaust fans or open a window during and after bathing/showering, dishwashing, using the dishwasher, cooking, or using the clothes dryer.
  • Use a towel or squeegee to dry off wet surfaces after bathing. Bathtub or showers corners and joints, including tile crevices, are more susceptible to mold growth, so be sure to dry off those surfaces.
  • If condensation occurs on inside windows panes (a common winter problem), take the time to dry them off frequently.
  • Keep humidity levels as low as you can—no higher than 50%--all day long. An air conditioner or dehumidifier will help you keep the level low. Bear in mind that humidity levels change over the course of a day with changes in the moisture in the air and the air temperature, so you will need to check the humidity levels more than once a day.
  • Use an air conditioner or a dehumidifier during humid months.
  • Cover cold surfaces, such as cold water pipes, with insulation.
  • Add mold inhibitors to paints.
  • Clean bathrooms with mold-killing products.
  • Do not carpet bathrooms.
  • Quickly clean up and dry any liquids that might spill on carpets. If carpets stay wet, notify the landlord.
  • Use kitchen exhaust fans when cooking.
  • Avoid using humidifiers unless there is a medical reason to use one.
  • Avoid the use of gas heaters that are not properly vented to the outside of the home.
  • Ensure good air movement in your home.
  • Open windows when possible.
  • Don’t block air supply and return vents.
  • Keep dust off air supply vents.
  • Keep a few inches of space between furniture and walls.
  • Avoid clogs and overflows of drains and toilets.

When moisture problems do occur, it is critical to quickly identify the cause of moisture and to dry affected areas. Tenants should promptly notify their landlord when they find a moisture problem or mold growth. Common moisture problems include pipe leaks, roof leaks, sewage back-ups and over-flowing toilets, sinks, and bathtubs. Floodwaters can also cause mold problems. Tenants should inform landlords verbally then in writing to avoid misunderstandings. The tenant should keep a copy of this message for future reference. Using certified mail, return receipt requested, your landlord received your message.

9. What can be done about indoor mold?

Tenants and landlords should try to work cooperatively to investigate and correct moisture problems and remove mold growth. If mold can be seen or if a musty odor is present, a careful inspection of the home should be conducted. Pay attention to hidden areas, such as plumbing access areas, crawl spaces, behind mirrors and furniture, attics, closets and cupboards.

Correcting a mold problem requires fixing the underlying moisture problem, removing the mold, and keeping the home dry in the future. Mold growth should be cleaned from non-porous surfaces such as concrete, metal, glass, tile, and solid wood. Mold growth is difficult to clean from absorbent (porous) surfaces such as drywall, carpet, fleecy furnishings and insulation. These kinds of moldy materials should be removed and discarded. Merely applying a chemical such as bleach to drywall, without removing the mold source, is not an effective, permanent solution. Painting over mold is also not effective. Personal belongings can be kept if there is no mold growth on them. These items may need a deep cleaning to remove mold particles (spores) that have settled in the fabric.

There are numerous private contractors who specialize in inspecting or cleaning up mold in homes. These contractors are required to be licensed in Texas. The landlord may want to hire a licensed Mold Assessor to determine the extent of a mold problem and to develop a remediation protocol to address it. Under TDLR rules, the remediation of 25 contiguous square feet or more of visible mold in residential properties with 10 or more units must be conducted by a licensed Mold Remediator. Small areas of mold growth (less than 25 contiguous square feet) can be cleaned/removed by an owner or by maintenance staff. Please note that testing to determine what kind of mold is present is not required prior to remediation or cleaning.

10. What are my options if my landlord does not respond to my concerns?

Know Your Rights as a Tenant

First, you must understand your rights and responsibilities as a tenant. The following documents have helpful information and guidance:

You may wish to contact an attorney for legal assistance. If you need help finding an attorney, the State Bar of Texas offers a lawyer referral and information service at 1-800-252-9690.
Various tenant, apartment and consumer organizations may also have resources to help you.

Contact the Local Health Department

A tenant can try to file a complaint with the local city or county health department. Some cities or counties in larger metropolitan areas may have adopted ordinances that allow them to enforce building codes, or that authorize a local health department to declare a property a public health nuisance, and may be able to issue correction orders to the landlord.

Tenants may seek assistance from their local building code official, if there is one. The building official may inspect the unit to determine if it is structurally sound. They may also, in some cases, enforce maintenance provisions of the building code.

11. I live in public, governmentally-subsidized housing. Are there other options?

You may contact the public housing agency for their city or county. There may be a social worker assigned to public housing in your area who can mediate between you and your landlord. For public government-funded housing, a list of Public Housing Agencies for Texas by county and city is available on the U.S. Department of Housing and Urban Development (HUD) web site. Another option for residents of HUD-insured and HUD-assisted properties is calling the Multifamily Housing Complaint Line at (800) 685-8470 to report complaints with a property’s management on matters such as poor maintenance, dangers to health and safety, mismanagement and fraud. Tenants in public housing may want to pursue the other options described above, but the public housing agency should address tenants’ reasonable requests that are within the bounds of property maintenance and building code. If your housing is USDA subsidized, you may wish to file a complaint with the USDA.

Filing a Complaint

1. How soon do I have to file a complaint?

You must file a complaint within two years of the event described in the complaint. TDLR will not accept complaints filed after two years unless you can show good cause for late filing to TDLR’s Executive Director.

2. I don’t want the registrant to know I filed a complaint. May I file a complaint anonymously?

Yes, TDLR accepts anonymous complaints. To file anonymously, be sure to leave the “Complaining Party” space blank on the complaint form. Keep in mind, if you file anonymously, you will not receive updates from TDLR on the status of your complaint and you will not be able to provide any additional information TDLR may need.

3. Does TDLR open and investigate every complaint received?

No. If the information you provide in your complaint does not contain enough information for TDLR to determine that a violation may have occurred, TDLR will first seek additional information from you (if you did not file anonymously). If TDLR does not receive enough information following that request, your complaint may not be opened for investigation.

4. What happens after I file my complaint?

Please see our Complaint Investigation and Resolution page for a detailed explanation of the complaint process.

5. What is the status of a complaint I filed?

TDLR will mail you quarterly notices and will inform you of the resolution of your complaint. Please keep your address and phone number updated with TDLR.

6. How do I know if disciplinary action was taken against a licensee or registrant, or an unlicensed person or business?
If a complaint results in disciplinary action taken by TDLR, it will be posted in our Administrative Orders Search for three years following the signed order.
