Do I need a permit for window or exterior door replacement in Town of Glastonbury?

Permit likely required

Most likely yes. Window or exterior door replacement usually requires a permit in Connecticut. Confirm the specifics with Town of Glastonbury.

Window and door replacement is not on the Connecticut list of work exempt from permit (CSBC R105.2), and the code requires a permit to alter or repair a building (CSBC R105.1); confirm the paperwork with the building official. Cutting a new or larger opening is a structural alteration and needs a permit. Sleeping room emergency escape openings must have a net clear opening of at least 5.7 sq ft under the Connecticut amendment to R310.2.1. Installers of preglazed or preassembled windows and doors do not need a glazier license (CGS 20-340(14)), but a hired installer still needs home improvement registration.
