Re: BO required to have CBO cert?
Paul,
No Requirement for Building Official.
I was a Building Official for a small community (less than 4,000 pop.) in Texas, for 3 years; and, I had only a State Plumbing Inspector's License. The only State requirement is that if you inspect Plumbing, you must have a State Plumbing Inspector's License. Other than that, it is up to the AHJ, to decide what qualifications and/or certifications they "hope for".
Many municipalities use an Assistant City Manager/ Manager, City Planner, the Mayor, Public Works Director, Fire Chief, or anyone else; who they feel will properly appy the political whims of the AHJ; and not offend any benefactors of the City governing body.
In other words; compliance with the wishes of the Local Home Builder's Association is an amendment to the adopted codes.
