ADU Contractor Utah — Accessory Dwelling Units, Guest Suites & Backyard Cottages
A&E builds ADUs across Utah's southern and northern counties. Detached guest suites, backyard rental units, and multigenerational living solutions — licensed B-100 General Contractor, fully permitted, built to Utah building code.
The Benefits of an ADU on Your Utah Property
An accessory dwelling unit — commonly called an ADU, granny flat, backyard cottage, or in-law suite — is one of the most financially powerful improvements a Utah homeowner can make. A properly built ADU on your property generates rental income, provides housing for family members, increases your property's appraised value, and gives you maximum flexibility for how your property is used now and in the future. At A&E Hardscape & Construction we build ADUs across Utah as a licensed B-100 General Contractor — from detached backyard cottages in Davis County and Weber County to multigenerational guest suites for mountain properties in Summit County and Wasatch County.
Utah passed legislation in 2021 requiring most cities and counties to allow ADUs on single-family lots — making now the best time to add an ADU to your Utah property before regulations tighten. Every A&E ADU project is handled from start to finish — zoning research, permit application, foundation pour, full construction, electrical and plumbing, interior finish, and final inspection. We manage every phase so you don't have to. Call 435-253-5322 for a free ADU consultation.

What You Need to Know About ADUs in Utah
ADU rules vary by city and county. Here's what every Utah homeowner should know before building.
Utah ADU Law
In 2021 Utah passed ADU legislation requiring most cities to allow at least one ADU per single-family residential lot. This opened up ADU opportunities across Utah that previously weren't available. Requirements including lot size minimums, setbacks, and owner-occupancy rules still vary by city and county — A&E confirms all local requirements for your specific address.
ADU Types in Utah
Utah ADUs come in three main forms — detached ADUs (separate structures behind or beside the main home), attached ADUs (additions to the main structure), and garage conversions (converting an existing detached garage to living space). A&E builds all three types across Utah. Detached ADUs are the most popular choice for new construction.
ADU Rental Income
A properly built ADU in Utah can generate $800–$2,000+ per month in rental income depending on location and size. Davis County, Weber County, and Iron County markets have strong rental demand. Park City and Summit County ADUs command premium rental rates. A&E helps homeowners understand the rental potential for their specific location.
Multigenerational Living
ADUs are one of the most practical solutions for multigenerational living — giving aging parents or adult children their own space on the same property while maintaining privacy and independence for everyone. This is one of the fastest growing ADU use cases across all Utah service areas.
ADU Financing
ADU construction in Utah can be financed through home equity loans, cash-out refinancing, construction loans, and in some cases renovation loans. The rental income an ADU generates can often offset a significant portion of the financing cost. Consult with your lender about the best financing option for your situation.
ADU Permitting Timeline
ADU permit approval in Utah typically takes 4–12 weeks depending on your city and the completeness of your permit application. A&E prepares thorough permit applications to minimize back-and-forth with building departments. Once permits are approved construction typically takes 3–5 months.
Why Utah Homeowners Choose A&E to Build Their ADU
An ADU is the most complex project most homeowners will ever undertake on their property. It involves zoning research, permit applications with architectural drawings, foundation engineering, full framing and roofing, electrical service, plumbing, insulation, drywall, flooring, cabinets, fixtures, and final inspections across multiple trades. Most contractors specialize in one or two of these areas — A&E is a licensed B-100 General Contractor that coordinates every trade involved in an ADU build from a single point of contact. You don't manage multiple contractors. You don't chase permits. You don't coordinate inspections. A&E handles every phase of your ADU project from first consultation to move-in day.

Are ADUs legal in Utah?

Requirements vary by city including minimum lot size, setbacks, height limits, and owner-occupancy rules. A&E confirms all local requirements for your specific address in Davis County, Iron County, and all 9 Utah counties during the free consultation.
How long does it take to build an ADU in Utah?
ADU construction in Utah typically takes 4–8 months from permit application to move-in. Permit approval alone takes 4–12 weeks depending on your city. Construction takes 3–5 months once permits are approved. A&E manages the full timeline from permit application through final inspection and certificate of occupancy.
Can an ADU be rented out in Utah?
Yes. ADUs in Utah can typically be rented as long-term rental units subject to local zoning rules. Some Utah cities require owner-occupancy of either the main home or the ADU. Short-term rental rules vary significantly by city — Summit County and Wasatch County have specific short-term rental regulations. A&E confirms all rental restrictions for your specific city during the planning phase.

What Utah Homeowners Say About Our ADU Builds
"A&E built a one-bedroom ADU in our Layton backyard. They handled every permit, coordinated all the trades, and managed the entire project from start to finish. Our ADU is now rented out and paying for itself. Best investment we've ever made."
"We hired A&E to build a detached guest suite at our Cedar City property for my aging parents. A&E handled everything — permits, foundation, framing, electrical, plumbing, interior finish. The quality is the same as our main home. My parents love it."
"A&E built a studio ADU at our Ogden property. The permit process was completely managed by A&E — I didn't have to deal with the city once. The finished unit is beautiful and already generating rental income."
