Re: IRC table R301.2(1)
In Texas, we did. By the way; there are some changes to Table R301.2(1); and if adopting the 2009 IRC they should be noted.
In Oklahoma however, I'm finding code adoption in many jurisdictions isn't taken very seriously and/or without good legal advise; for example;
"5-301: BUILDING CODE ADOPTED:
A certain document, at least one copy of which is on file at the office of the city clerk, being marked and designated as "international building code", the latest edition thereof, and any revisions or amendments thereto, is hereto adopted as the building code of the city for the control of buildings and structures therein provided. Each and all of the regulations, provisions, penalties, conditions and terms of the international building code are hereby referred to, adopted and made a part hereof, as if fully set out in this code, with additions, insertions and changes, if any, prescribed in this chapter." (no additions, insertions and changes listed)
(Several Oklahoma municipalities have similar adoptions.)
If you don't see a problem here; you might want to rethink the adoption of your AHJ's codes; and get some good legal advise.
