What Salt Lake City Requires for an ADU

Every Utah city sets its own rules for accessory dwelling units on top of state law. Here's what matters most for Salt Lake City properties.

📏

Size Limits

Detached ADUs are capped at 1,000 sq ft in Salt Lake City. There's no size cap if you build an internal ADU inside your existing home instead.

🚗

Parking

Most Salt Lake City neighborhoods require one off-street parking space per ADU — though homes near a TRAX stop or UTA bus route may qualify for a waiver.

🏡

Owner-Occupancy

Salt Lake City requires that either your main home or your ADU be your primary residence, and short-term rentals like Airbnb aren't allowed on ADUs here.

Ordinances change and every lot is different — we confirm your exact zoning, setbacks, and options during your free site visit, at no cost.

Three Ways to Add an ADU in Salt Lake City

Whichever fits your lot and budget, we handle design, permits, construction, and final inspection.

🚗

Garage Conversion ADU

Typical Range
$50K – $120K

Convert an existing garage into a legal Salt Lake City rental unit — since you're working with a structure that's already there, it sidesteps the city's detached-ADU setback and height rules entirely.

🏠

Custom Stickbuilt ADU

Typical Range
$120K – $300K

Built on-site to match your home's architecture — ideal if your Salt Lake City lot has room for a fully custom layout beyond a standard modular footprint.

Salt Lake City ADU FAQ

Do I have to live on the property to build an ADU in Salt Lake City? +
Utah's statewide law removed the owner-occupancy requirement in 2021, but Salt Lake City has kept its own local rule: either your primary home or the ADU has to be your permanent residence. We'll walk through exactly what that means for your property during your free estimate.
Can I rent my Salt Lake City ADU on Airbnb? +
Not currently — Salt Lake City restricts ADUs to long-term rentals only, no short-term or vacation rentals. Long-term rental income is still a strong option; we can help you run the numbers during your free consultation.
