Construction started prior to August 1, 2017
Construction to plans approved to the previously adopted mandatory building codes that began prior to August 1, 2017, or prior to the manufacturer’s effective transition date, must be completed, inspected in the plant by a Texas approved third party inspector, and labeled (TX decal must be permanently attached to the unit) by no later than January 31, 2018 or the unit shall not be eligible for a Texas decal.
On-site construction started prior to August 1, 2017, may also be completed to the mandatory building codes that were in effect at the start of the on-site construction provided that construction started prior to 8/1/2017. There are 2 exceptions to this as follows:
- Some manufacturers chose to start constructing to these codes prior to the 8/1/17 effective date, so if the approved plans identify the applicable mandatory building codes as the 2015 International Codes and the 2014 NEC, then the on-site construction will be performed to these code editions. Please contact us at firstname.lastname@example.org if you need to know if the manufacturer you are working with transitioned to the new codes prior to 8/1/17.
- If you broke ground for a building that did not enter construction at the plant until on or after 8/1/17, then the installation must also comply with the new mandatory building codes
