The responsibility of the Building Department is to review all construction documents for compliance with the Connecticut State Building Code, and to issue necessary permits. It is also the responsibility of the Building Department to monitor all projects while under construction, perform a final inspection and issue a Certificate of Occupancy. We answer emergency calls from fire dispatch to assess damage to determine if structures may be occupied.


According to the Connecticut State Building Code section R109.3: It shall be the duty of the permit holder or their agent to notify the building official that such work is ready for inspection.
