Regarding Texas code:
I am new to this forum so please tolerate any newbie issues.

Almost all of my business is new construction phase inspections in Montgomery Co. in TX. Each municipality adopts its desired code revision and may modify it for local use. In the counties, the code used in the county seats is applicable.

However, in many small municipalities and in most county areas, there is no code enforcement. Therefore, there is in effect, no code. However, the legislature passed a law in Sept. 2007 that will apply to housing starts after Sept. 2008.

In a nutshell, the law requires the builder in areas without enforcement to hire a third party inspector to accomplish a prepour, preinsulation and final inspection and report completion of the inspections to the TRCC.

I hope this helps with the previous question.
