DER, Commercial Construction/Life Safety Section (CCLSS)

The The Commercial Construction/Life Safety Section (CCLSS) provides oversight for the third party inspections 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 or to discuss whether a project qualifies for the program, please contact the Permits and Review Division at (301) 883-5907.

Use and Occupancy Inspections

Once an inspection request is made utilizing the Automated Inspection Request System or online (refer to our webpage to schedule an inspection by phone or online) an inspector will contact you between 7 a.m. and 9 a.m. and schedule an appointment within the next five working days.
