The Texas Industrialized Building Code Council met August 22 in Austin. The agenda and the Staff Reports are online. The meeting was archived and is available on TDLR's YouTube channel.

Changes to the Industrialized Housing and Buildings law.- Senate Bill 1264 passed by the 84th Texas Legislature, amended Occupations Code, Chapter 1202, relating to the regulation of certain industrialized housing and industrialized buildings. Senate Bill 1264 and the changes to Chapter 1202 became effective September 1, 2015. TDLR encourages all persons interested in the Industrialized Housing and Buildings program to review the updated Occupations Code, Chapter 1202. SB 1264 amended the Occupations Code to increase the maximum height allowed for industrialized housing and industrialized buildings to four stories or 60 feet in height. Previously the maximum number of stories and height allowed for industrialized housing and industrialized buildings was three stories or 49 feet.


The site inspection, or installation inspection report forms have been revised due to changes to the Industrialized Housing and Buildings (IHB) rules requiring industrialized builders to notify and provide the consumer specific information in accordance with §70.78(c) of the rules governing industrialized housing and buildings. Third party inspectors, third party site inspectors, and engineers and architects approved to perform installation inspections must begin using these forms immediately.

The new forms are as follows:

All of the above forms together make up the complete on-site, or installation, inspection report for industrialized housing and buildings (Form #IHB 233 is not used for industrialized buildings).

The new forms are fillable PDFs that allow users to type directly into the form and save the form to their computer or other electronic device.


Revisions to the rules governing Industrialized Housing and Buildings (IHB) became effective May 1, 2014. Industrialized Builders are now required to present the purchaser of an industrialized house information regarding the limits for filing consumer complaints on industrialized housing and a copy of the final on-site inspection report as defined in 70.10(a) of the administrative rules. TDLR developed a form to help industrialized builders comply with the new administrative rule requirements. Download Consumer Notice, form IHB600. Industrialized builders are not required to use this form, but they are required to notify and provide the consumer specific documents and information in accordance with 70.78(c) of the rules governing industrialized housing and buildings.

'Man camp' is the term currently being used in the modular industry to describe buildings constructed for use of employees of companies involved in oil and gas exploration. These are generally transient lodging buildings and related structures such as dining facilities, commercial kitchens, laundry rooms, and recreation buildings. These buildings are generally covered by the IHB law and rules unless they meet the exemptions in §1202.001 through 1202.003. TDLR has prepared a PowerPoint presentation that outlines the requirements of the IHB law and rules as they apply to these buildings. The PowerPoint presentation can be viewed online. The presentation is also available for download as a PDF (963 KB).
