The Commercial Construction and Life Safety Section (CCLSS) provides oversight for the
Third Party Inspection process required for
new commercial construction in the County. 
In addition, CCLSS provides commercial electrical inspections for commercial projects
that are not third-party.

The Third Party Inspection Program (TPIP) provides the framework for Third Party Inspection agents hired by the owner to evaluate the work of the various trades.  These professionals then provide certifications to the County attesting to the quality of work as related to the County Code.  To obtain a copy of the TPIP Manual, click the following link:
