Norwalk, CT Accessory Structures: ADU Owner Occupancy (2026)

Norwalk's accessory apartment ordinance ties every unit's legal status to continuous owner-occupancy of the host property. Norwalk Code § 118-420(B)(2) states simply that "the owner of the property must reside on the premises," a condition that runs alongside the zone, lot-size and three-year existence requirements in the rest of Subsection B. " Because § 118-420(D)(1) already channels approval solely through the Zoning Inspector rather than the Zoning Commission, that same office is responsible for collecting and checking the annual paperwork, effectively making owner-occupancy a standing condition of the permit rather than a fact established only when the apartment was first authorized.

The ordinance was amended effective January 27, 1984 and September 26, 1986 after its original 1982 adoption, and the affidavit language sits in the same procedural subsection that limits initial approval authority to Zoning Inspector review, tying the annual filing to the same office that issued the original approval.
