From time to time, the Building Inspections Division will develop technical bulletins that are specific for certain technical issues.  This section will be continually updated.  The following files are in PDF file format and require Adobe Acrobat in order to be able to view them.

TDLR Project Verification:  Per SB 484, commercial and multifamily projects with a construction value exceeding $50,000 must be registered with TDLR's Architectural Barriers Division prior to submitting a permit application to a City for review.  Without a TDLR project number that is verifiable, a permit application will not be accepted for review.  For questions or further information, contact a technical information specialist by calling toll free at 1-877-278-0999 or by sending your inquiry via email to [email protected].
