How our property map screens Uintah 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; Uintah makes the decision.
- No numeric external minimum is recorded for Uintah. The map keeps the statewide 11,000 sq ft external screen and shows the researched status (limited) on the property report.
- Because external ADUs are limited in the Uintah research, the map does not mark a new external ADU as likely there.
- "Likely" above 15,000 sq ft is this site's planning band for a large recorded lot. It is not a sentence in the Uintah 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 Uintah
Uintah City has its own ADU chapter covering purpose, conditional uses and site-development standards. Confirm the parcel is within Uintah City rather than Uintah County or another nearby jurisdiction. We can help review the proposed unit against the current city chapter, including the relevant site and utility questions before detailed design.

Common Uintah ADU questions
Can you build an ADU in Uintah?
Uintah: internal ADUs allowed with conditions; detached ADUs allowed only in limited cases. This is planning guidance, not a permit. Confirm the zone on your parcel with Uintah.
What lot size does Uintah require for an ADU?
Internal ADU: Statewide statute includes a small-lot pathway around 6,000 sq ft for many internal ADUs — confirm how Uintah applies it on your zone. Detached ADU: No automatic statewide 11,000 sq ft detached mandate applies under the specified-municipality screen; local rules control.
What does it cost to build an ADU in Uintah?
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 Uintah?
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 Uintah 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.
