Is Drywall needed on exterior wall of garage on concrete block, 2-story house in Florida
Drywall on the inside of an exterior wall has not been required in any of the states I have lived, it is required for fire protection on stick built, but a concrete block wall has the appropriate fire ratings and should require nothing. call your fire marshal to verify local code as far as I know drywall is not required on an interior wall even from a garage to living space with block walls and your fire marshal or fire department can verify this. I think your inspector is nuts.
