No, a complete certificate of occupancy (COO) is not needed if the ownership is changing but the occupancy is not.
If the property is a rental property and the owner/landlord is selling to a new owner/landlord and the same tenants will remain, the current owner/landlord must provide the new owner/landlord with the current COO showing it was inspected and complete. Before closing, the new owner/landlord must register as a landlord.
If the current owner/landlord sells to the current tenants and the tenants will continue to occupy the house, a smoke and carbon inspection only is needed. The cost of this is $100.
If a parent sells to a child who currently lives in the house, only a smoke and carbon inspection is needed ($100). You must show proof of residency that the child currently lives in the house.
If a parent sells to a child who does not currently live in the house, this requires a complete COO inspection.
