Norwalk, CT Home Business: Zoning & Home Occupation Permits (2026)

Home occupations are treated as an accessory use, not a principal use, in Norwalk's single-family residence zones, and § 118-310B(4)(a) sets the standard for the AAA Residence Zone (two-acre-plus lots); the AA Residence Zone applies the identical restrictions at § 118-320B(4)(a). Both provisions cap a dwelling to one home occupation, require it to be conducted entirely within the house, and bar any change to the residential character of the property. Five numbered conditions follow: the operator may employ no more than one person who does not live in the dwelling; the business cannot store stock-in-trade or sell commodities from the premises; it is limited to 25% of the first-floor area, capped at 500 square feet no matter how large the house is; it cannot be a barber or beautician shop or involve the sale or care of animals; and it cannot manufacture, convert, or fabricate any material or product.

These accessory-use standards operate alongside § 118-910's rules on accessory-building location and the signage cap in § 118-1295A(1)(a), which allows only a two-square-foot, nonilluminated sign to announce the occupation. Because a home occupation is an accessory use rather than a Special Permit use in these zones, it does not go through the Zoning Commission's Special Permit process under § 118-1450; instead, compliance is checked through the zoning approval and building permit process in § 118-1292A(1) whenever a related building permit, sign, or certificate of occupancy is sought, and through the Zoning Inspector's general enforcement authority.
