To obtain a Certificate of Occupancy or Certificate of Approval all inspections must pass, according to the State of Connecticut code. Once a final inspection passes the Certificate will go out to the other departments for approvals. The Building Department highly recommends checking in with any of the other departments that had to approve your permit and make sure all requirements are met. Once all departments have put in their approvals, a copy of the Certificate will be emailed.
From the Connecticut General Statutes: Pursuant to subsection (a) of section 29-265 of the Connecticut General Statutes, no building or structure erected or altered in any municipality after October 1, 1970, shall be occupied or used, in whole or in part, until a certificate of occupancy has been issued by the building official, certifying that such building or structure or work performed pursuant to the building permit substantially complies with the provisions of the State Building Code.
