State law: detached ADUs from October 1, 2026

West Point is a “specified municipality” under Utah S.B. 284. Beginning October 1, 2026, it must permit one detached ADU as a permitted use on a lot of 11,000 sq ft or more that has a detached single-family home. The city can still apply setbacks, height, design, owner-occupancy and limited parking rules, and it may allow detached ADUs on smaller lots. How the state ADU laws work.

How our property map screens West Point lots

The map colors parcels using the rules on this page and the recorded lot size. A color is a planning screen, not a permit; West Point makes the decision.

  • "Likely" above 15,000 sq ft is this site's planning band for a large recorded lot. It is not a sentence in the West Point code. Owner occupancy, parking, setbacks, zones, and HOA rules below still have to be checked.

Planned communities, PRDs and PUDs

Reviewed on September 22, 2026 against this city's research file, its published ADU page where one was found, and Utah meeting packets. No adopted sentence was confirmed that allows or bans an ADU in every PUD, PRD, PRUD, or planned community. If the assessor class or subdivision name says PUD, PRD, PRUD, planned unit development, planned residential development, planned community, resort community, or master planned community, the map keeps that lot highly unlikely regardless of size. A plat, CC&Rs, or development agreement can still prohibit an ADU where the zone allows one.

Planning notes for West Point

West Point describes internal, attached and detached ADUs and directs each type to Section 17.70.060. The standards differ by unit type, so an addition and a backyard cottage should be evaluated separately. We can help compare those choices against the lot and your intended long-term use.

  • Internal, addition or detached concept
  • Measured site plan and floor areas
  • Owner occupancy and intended rental duration

Common West Point ADU questions

Can you build an ADU in West Point?

What lot size does West Point require for an ADU?

Internal ADU: Statewide statute includes a small-lot pathway around 6,000 sq ft for many internal ADUs — confirm how West Point applies it on your zone. Detached ADU: 11,000 sq ft minimum. Statewide detached floor for specified municipalities: roughly 11,000 sq ft on qualifying single-family lots (operative Oct 1, 2026). Local code may allow detached ADUs on smaller lots sooner.

What does it cost to build an ADU in West Point?

Wasatch Front planning bands are often about $55,000–$145,000 for an internal suite, $70,000–$175,000 for a garage conversion, and $95,000–$250,000 or more for a new detached unit, before unusual site work. These are planning ranges, not bids.

Can an HOA block an ADU in West Point?

City approval does not override CC&Rs or plat notes. Read the HOA documents and your subdivision plat before you design. A private restriction can stop a unit the city would otherwise allow.

Before you design: general checks for any Utah ADU

General planning advice, not West Point code.

  • Confirm the zoning district on the city zoning map. The county assessor’s “residential” class is not zoning.
  • Read your HOA CC&Rs and subdivision plat notes; private restrictions can block a unit the city allows.
  • Sketch existing and proposed parking. Driveway geometry and access often decide what fits.
  • Ask early about sewer, water and electrical capacity; utilities can force a redesign.
  • Expanding a building’s footprint usually triggers full setback and height rules.
