Property owners must file a Certificate of Occupancy application if construction or alteration has changed their building's use, occupancy, or means of exit. You must file an application for a Certificate of Occupancy to begin the inspection process before the certificate is issued.
The Department of Buildings (DOB) provides Letters of No Objection to confirm the legal use of a building constructed before 1938. To request a Letter of No Objection, go to the DOB Borough Office where your property is located. Bring any property-related materials you have that demonstrate the longstanding use of the property. Examples of such materials include old property surveys, deeds, water bills, tax assessments, or photographs.
Before you visit a DOB Borough Office, research the construction records for the property by using the online Buildings Information System.
