West Haven

Detached allowed with a land-use permit

West Haven allows internal and detached accessory dwellings. A land-use permit and a site plan are part of the process. HOA covenants, common in newer west-side subdivisions, are the owner’s to resolve.

Internal ADU

Permitted.

Detached ADU

Permitted with a land-use permit. Site, floor, and parking plans are expected.

Lot

Confirm with the city. Statewide detached path on 11,000 sf lots from October 1, 2026.

Size

Per West Haven Code Chapter 19. The ADU cannot exceed the primary dwelling under the 2026 state floor.

Parking

Shown on the site plan. Subject to the 2026 state cap.

Owner occupancy

Owner occupancy is required.

Rental

Confirm current short-term rules. Long-term occupancy is the safe assumption.

Design

Chapter 19 governs. Newer subdivisions often have covenants tighter than city code — those are yours to open.
