Do I need a permit for residential demolition in New Haven?
Yes. In Connecticut, residential demolition generally requires a permit, and New Haven is no exception.
No one may demolish any building, structure, or part of one without a permit from the local building official, and the applicant must show utility severance certificates, insurance, a license or exemption, and a hold harmless declaration (CGS 29-406). An owner may demolish their own single-family home or outbuilding without a demolition license if it is 30 feet or less in height, the owner is on site, and clearance to other structures and roads at least equals its height (CGS 29-402(c)). Department of Public Health rules define a facility to include single-family homes and require notice at least 10 days before any demolition, and before disturbing more than 10 linear feet or 25 sq ft of asbestos-containing material (Regs. 19a-332a-1 and 19a-332a-3). Adjoining owners must be notified by registered or certified mail before demolition starts (CGS 29-407), and a town may impose a waiting period of up to 180 days by ordinance (CGS 29-406(b)).
