Farr West

Detached allowed

Farr West adopted a dedicated detached-ADU ordinance. Units are sized between 400 and 1,000 square feet, with a 20-foot peak-height cap in the published planning-commission text. Applications have included a public hearing.

Internal ADU: Permitted. Not on lots smaller than 6,000 sf.
Detached ADU: Permitted under the city’s DADU code. Minimum 400 sf, maximum 1,000 sf in the adopted text. Peak height 20 feet. Sufficient setbacks, utilities, and parking are required.
Lot: Not on lots smaller than 6,000 square feet. A lot of 11,000 square feet or larger with a permitted house is also covered by the statewide rule now in effect.
Size: 400–1,000 square feet, and a 20-foot peak, in the adopted DADU text we have. A city may keep a size cap. We did not find a 2026 ordinance repealing those figures. Confirm before drawing larger.
Parking: An off-street parking plan is required, and not more than the state cap: one stall under 650 square feet, two at 650 and above.
Owner occupancy: Owner occupancy is required. Long-term occupancy only (30 days or more).
Rental: Thirty days or more.
Design: The mayor’s public comments emphasize lot area, setbacks, utilities, and parking. Plan on a hearing so neighbors can comment.

Notes

Site, floor, and parking plans are part of a complete application.

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.
