If I have 2 buildings located on one property do I need a certificate of occupancy for each building or does 1 certificate cover all buildings?
Depends on the 1) building zone, 2) jurisdiction (city or county), 3) occupancy...office, apartments, retail, etc. (You can’t get one for “single family residential.) (See ICC R110.1)
Check with your local Building Department. They check for fire safety, setback requirements, adequate parking, etc.
