How to Choose an ADU Builder in Utah: A 10-Point Checklist

July 31, 2026 · Utah Backyard ADUs
← Back to all guides

An ADU is a major project, often the largest single home investment a homeowner will make after buying the house itself. The builder you choose matters more than almost any other decision in the process. Here's what to actually check.

1. A Real, Verifiable Utah General Contractor License

Ask for the license number directly and look it up yourself through the Utah Division of Professional Licensing (DOPL). A legitimate builder will give you this without hesitation. For reference, ours is Utah GC License #14296577-5501.

2. Proof of Insurance and Bonding

General liability insurance protects you if something goes wrong on your property during construction. Ask for a certificate of insurance, not just a verbal assurance.

3. A Real Portfolio of Local, Completed Projects

Renderings and stock photos are easy to produce. Ask specifically for photos of projects the builder has personally completed in Utah, ideally ones you can drive by. Our gallery shows completed work, not just concept renderings.

4. Who Actually Manages Your Project

Some companies sell the job, then hand it off entirely to subcontractors you never meet. Ask directly: who will be on-site managing this day to day, and how much of the actual construction work is subcontracted out? Neither answer is automatically wrong, but you deserve to know it upfront.

5. Contract Structure: Fixed Price vs. Cost-Plus

Understand exactly what you're signing. A fixed-price (lump sum) contract gives you cost certainty upfront. A cost-plus contract can offer more flexibility on selections but requires more trust and clearer reporting on actual costs. Neither is a red flag by itself — a vague contract that doesn't specify which one you have, is.

6. Permitting and Inspections Included, Not Billed as an Extra

Confirm in writing that permit applications, plan revisions, and every required inspection are handled by the builder as part of the scope, not passed back to you or billed piecemeal later.

7. A Realistic Timeline, Not an Aspirational One

Be skeptical of a builder who promises a custom stickbuilt ADU in 6 weeks. Realistic ranges in Utah run 2-3 months for a garage conversion, 3-5 months for modular, and 5-8 months for custom stickbuilt, and that's after permitting is complete. See our full cost and timeline breakdown.

8. Willingness to Provide References

Ask to speak with two or three past clients directly, not just read testimonials on a website. A builder confident in their work will connect you without hesitation.

9. Clear, Responsive Communication From the First Call

How a builder communicates during the sales process is usually a preview of how they'll communicate during construction. Slow replies and vague answers now rarely improve once you've signed.

10. A Contract That Spells Out Draws, Change Orders, and Selections

Payment draw schedules, how change orders get priced and approved, and what's included vs. considered an upgrade should all be explicit in writing before you sign anything.
