Cambridge allows home occupations as accessory uses in residential zones when incidental to the dwelling, with restrictions on employees, signs, customer traffic, and exterior changes under the Zoning Ordinance.
The Cambridge Zoning Ordinance permits home occupations in residential districts provided the use is clearly incidental to residential use, conducted entirely within the dwelling by residents, and does not alter the residential character of the property. No exterior signs, outdoor storage, or structural changes visible from the street are allowed. Customer and client visits must be limited and cannot generate excessive traffic or parking demand. Businesses requiring regular employees, retail sales, or manufacturing typically require a special permit from the Board of Zoning Appeal. All home businesses must register with the City Clerk for a business certificate.
