West Point

Detached allowed on 10,000 sf lots

West Point publishes a dedicated ADU chapter. Internal and attached units start at 6,000 sf lots. Detached units start at 10,000 sf, with size, setback, height, and fire-access rules written in the code.

Internal ADU: Permitted on lots of 6,000 sf or larger. No local cap on habitable area. Must meet Utah Code §10-9a-530.
Detached ADU: Permitted on lots of 10,000 sf or larger, on a permanent foundation, similar in appearance to the house. No basement. Not a mobile home, RV, or shipping container.
Lot: Internal and attached: 6,000 square feet. Detached: 10,000 square feet, which is below the state floor and therefore allowed. A lot of 11,000 square feet or larger is also covered by the statewide rule now in effect.
Size: Detached: 650 square feet maximum on lots under 12,000 square feet; 800 square feet on lots of 12,000 and larger. Attached: 50% of the primary habitable footprint, not more than 800 square feet. Those caps are still a lawful local limit unless the city has amended 17.70.060.
Parking: Internal and attached: one off-street stall. The detached rule asks for two. On a unit under 650 square feet, state law allows the city to require only one. Confirm how West Point is applying that.
Owner occupancy: Owner must live in the principal or accessory unit, with written exceptions for temporary absence (military, job, sabbatical, up to three years) and medical placement.
Rental: Thirty consecutive days or more. Short-term rental is not the path.
Design: Side or rear entrance. One bedroom and a three-quarter bath minimum, plus a kitchen. Same utility lines as the house. Ten-foot side and rear setbacks for a detached unit. Not taller than the primary dwelling. Fire hydrant within 500 feet of the front entrance; building not more than 150 feet from the public road.

Notes

West Point is one of the few Davis cities with a complete, numbered ADU table. We design to 17.70.060.

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.
