The Town of Bedford is part of the Plus One ADU Program. Currently, Bedford allows up to one accessory dwelling unit (ADU) per home in all single-family residential zones, upon approval of application by the Planning Board. Accessory cottages are not permitted; ADUs must be attached to the main dwelling unless in districts R-2A or R-4A. No permit shall be granted until 5 years after the construction of the entire structure including accessory structures. Permits are valid for 5 years. The accessory apartment cannot be more than 25% of the floor space of the main dwelling (with a minimum of 400 min/800 max square footage). A maximum of 5 people may occupy the lot. Additionally, the regulation includes specifications on application requirements, information, fees, change in ownership, parking requirements, and more.
