Cambridge bans most exterior home-business signage. A small professional nameplate under about 1 sq ft may be allowed, but illuminated or commercial-style signs are not permitted at residences.
Under the Cambridge Zoning Ordinance, home occupations must preserve the residential character of the neighborhood. This means exterior signage is tightly restricted. A small non-illuminated nameplate or professional plaque, typically no more than about 1 square foot, attached flat to the dwelling is generally allowed for professional offices such as attorneys, doctors, or therapists operating from the home. Freestanding lawn signs, window signs, illuminated signs, and commercial-style signs are not permitted in residential districts for home occupations. Larger or non-conforming signs require a variance from the Board of Zoning Appeal, which is rarely granted. Historic districts apply additional sign review through the Cambridge Historical Commission. Online and digital marketing do not trigger zoning issues and are the typical approach for Cambridge home businesses.
