Short-form permit and trade permit check for insulation or air-sealing work

Boston's insulation guide states that a short-form permit is used for replacing existing insulation or adding new insulation. Boston's electrical permit page also says electrical permits are needed for electrical installations, alterations, and repairs, including gut renovations that involve electrical work such as insulation or siding on a home, so insulation and air-sealing projects should be checked for building, electrical, wall-opening, landmark, or broader renovation requirements before work starts.
