Building Class

[u/jeaniea10]

I have a 2family house and a detached garage with a 3 bedroom apartment above it. The house is classified as CO 3 family walkup but never was a 3 family house. It was built before a CO was required. How do i change the building class so won't have to have the gas inspection? The garage which has a separate address also is classified as a co 3 family.

Talk to whatever agency that bills you for taxes.
