Siding guides by area
What every guide covers
Permits
Every town enforces the 2022 Connecticut State Building Code (CGS 29-253). Its siding permit exemption stops at the 25 percent repair limit (amended R105.2), and a contractor may not start before the permit is issued (CGS 20-427).
Historic district review
Inside a local historic district or on a locally designated property, siding changes open to view from a public street need the commission’s certificate of appropriateness “whether or not a building permit is required” (CGS 7-147d, 7-147s). Ordinary maintenance or repair that does not change appearance is exempt (CGS 7-147j), and National Register listing alone brings no commission review. Norwich’s rules say synthetic siding will not be approved as the dominant material on a historic structure.
The pre-1978 lead rule
The EPA Renovation, Repair and Painting rule (40 CFR 745) covers paid work that disturbs painted surfaces on most housing built before 1978. Its 20-square-foot exterior exclusion never covers demolition, which EPA defines as removing a painted component in a way that destroys or ruins it. The firm must be EPA-certified.

Common questions about siding in Connecticut
Do I need a permit to replace siding in Connecticut?
Yes, for a full re-siding. The permit exemption in the 2022 Connecticut State Building Code stops at repairs limited to 25 percent of the siding within one calendar year.
Does a historic district commission have to approve new siding?
Only inside a local historic district or on a locally designated property, where siding changes visible from a public street need a certificate of appropriateness before the building permit is issued. The guides above list which towns have them.
Does the EPA lead rule apply to re-siding an older house?
Yes, when paid work disturbs painted surfaces on a house built before 1978, unless certified testing finds no lead paint on them. The 20-square-foot small-job exclusion never covers demolition, such as tearing off painted siding in a way that ruins it.
