Do I need a permit for water heater replacement in Forest Hills?
Yes. In Tennessee, water heater replacement generally requires a permit, and Forest Hills is no exception.
Replacing a water heater generally requires a permit; temperature-and-pressure relief valve, discharge piping, venting, and (for gas) combustion-air and flue requirements are enforced. Switching fuel type, relocating the unit, or converting to a tankless model can add mechanical/gas permit and inspection requirements; confirm locally. Plumbing work in Forest Hills is a trade item, and the City states that all plumbing trade inspections are conducted by Metro Nashville, so a water heater replacement needs a Metro Nashville plumbing permit and inspection rather than being exempt. A gas water heater adds a fuel piping and venting scope that Metro Nashville also inspects, so confirm whether a gas inspection applies to your replacement. Tennessee limits homeowner plumbing work and requires a licensed plumber for most jobs, so confirm eligibility before applying and check with the City Building and Zoning office if any City permit also applies.
