Sunset

Confirm detached with the city

Sunset is over the 5,000-resident line, so the statewide detached rule applies. We did not find an adopted 2026 ordinance. A draft numbered 2026-06 is written toward an October 20, 2026 meeting and is not law. Internal units follow House Bill 82. Many lots here will not clear 11,000 square feet.

Internal ADU: Permitted in most residential zones under House Bill 82.
Detached ADU: On a lot of 11,000 square feet or larger with a permitted house, state law requires a permitted use, not a conditional use. Confirm the local size, height, and setback table. Many lots will not clear 11,000 square feet.
Lot: 11,000 square feet is the statewide detached floor, now in effect. The city may allow a smaller lot. Feasibility is whether a second building fits.
Size: Per ordinance. The city may limit size and may require that the unit not exceed the house.
Parking: Per ordinance, and not more than the state cap: one stall under 650 square feet, two at 650 and above.
Owner occupancy: Owner occupancy is typical. Confirm.
Rental: Long-term occupancy is the usual rule.
Design: Setbacks, height, and coverage remain local. Lots here are often tighter than in west Davis.

Notes

Smaller lots are common. Feasibility — whether a detached building actually fits — is the first drawing.

Statewide floor

Senate Bill 284, Utah Code §10-21-304, has been in effect since October 1, 2026. Every city on this list must allow a detached ADU as a permitted use — not a conditional use — on a lot of 11,000 square feet or larger that already has a permitted single-family house. A city may also allow one on a smaller lot. It may still set size, height, coverage, setbacks, and owner occupancy, and it may require that the unit not be larger than the house, not sit in the front yard, and not be rented for fewer than 90 days. Parking may not exceed one stall under 650 square feet, or two stalls at 650 square feet and above. A printed ban, or a conditional-use requirement, on a qualifying lot conflicts with the statute even if the code book is late. Confirm the city’s ordinance before anyone draws.
