Do I need a permit for addition or structural alteration in Collierville?
Yes. In Tennessee, addition or structural alteration generally requires a permit, and Collierville is no exception.
Additions and structural alterations require a permit and plan review; expect separate trade permits for electrical, plumbing, and mechanical work tied into the project. Owner-builders may perform work on their own residence under TCA 62-6-103, but the permit, inspections, and code compliance are still required. A home addition or converting non-living space to conditioned living space is a permitted building project reviewed by the Collierville Building and Codes Division, applied for in person or through the Collierville iWorQ contractor portal. Additions must meet Collierville zoning for setbacks, height, and lot coverage, which is reviewed separately from the building permit, and the work must comply with the adopted 2018 International Codes. Collierville requires a state or county licensed contractor for all mechanical, plumbing, and electrical portions, and Tennessee requires a state contractor license for residential work at 25,000 dollars and above.
