Building Department Permit & Applications: Plymouth, Connecticut (CT)

The Town of Plymouth Building Department is responsible for the issuance of building permits and overseeing the construction of all structures in Town. The Plymouth Building Department reviews construction plans for compliance with the Connecticut State Building Code for all residential, commercial and municipal projects and issues necessary permits and monitors the projects while under construction.  They also review architectural, structural, mechanical, electrical, plumbing, alarm, sprinkler plans, and ADA handicapped accessibility. Once a project is complete and satisfactorily constructed the Plymouth Building Department will issue a Certificate of Occupancy so that the structure may be legally used for occupancy.
