Can you build your own house in Utah without a contractor’s license?

You must be the Utah property’s sole owner to qualify for the residential owner-builder exemption¹. The home must be for your noncommercial, nonpublic use¹. Owning Utah land does not, by itself, satisfy every condition of the exemption¹. Before buying with another person or through an entity, ask DOPL whether your ownership arrangement would meet the sole-owner condition.

Utah’s exemption also covers incidental structures for your noncommercial, nonpublic use as the sole owner¹. Examples include a shed, carport or detached garage associated with your home¹. If you plan space for a business or public activities, ask DOPL to review your intended use.

You can build up to 1 residential structure per year and 3 residential structures per five years under Utah’s exemption¹. Both limits apply to construction on your property as the sole owner, for your noncommercial, nonpublic use¹. A new year does not reset Utah’s five-year limit¹. Count your previous residential projects before using the exemption again.

Utah bases the exemption on your use of the home as well as how often you build¹. Even below the building limit, you must meet the noncommercial, nonpublic-use condition¹. If you plan to sell or rent the home, ask DOPL whether you qualify before signing the certification agreement.

You can hire help, but your Utah owner-builder exemption does not automatically cover everyone working on your house¹. Anyone else building your home needs a license if the Construction Trades Licensing Act requires one, unless an exemption applies¹. Before hiring someone who plans to work without the required license, check with DOPL.

Utah allows qualifying helpers to work under your direction as the property owner for no more than token compensation¹. Token compensation must be minimal compared with the work’s market value and unrelated to that value¹. Meals, refreshments and reasonable transportation costs are examples of incidental compensation¹. You cannot treat ordinary pay for construction labor as token compensation¹.

File Utah’s Owner / Builder Certification Agreement with the city or county building department where you will build⁴. Your local compliance agency issues the construction permit³. Utah’s state licensing division administers the codes but does not issue construction permits or conduct compliance inspections³. Ask your local building department what application materials you need and which fees you must pay.

Utah’s owner-builder exemption covers contractor licensing¹. You still need to meet the building-permit, inspection and code requirements that apply to your project¹. Before starting construction, discuss the certification agreement with your local building department. Ask that office how to arrange the required inspections.

Utah’s owner-builder exemption does not itself waive your building permit¹. For unincorporated land, 25 Utah counties are listed as requiring residential building permits². These include Carbon County, Duchesne County and Rich County².

Another 4 Utah counties have conditional building-permit requirements². They are San Juan County, Kane County, Wayne County and Juab County². A conditional rule does not mean your new owner-built house is exempt¹. Ask the building department serving your address which rule applies to the house you plan to build.

You still need to follow Utah’s applicable State Construction Code as an owner-builder¹. Utah’s current adoption includes the 2021 International Residential Code and its Appendix AQ, with state and incorporated local amendments⁵. The cited code adoption took effect in July 2026 and is marked as superseded in January 2027⁵. If your schedule crosses that change, ask your local building department which code edition will apply to your application.

Utah’s licensing exemption does not let you skip inspections or a required certificate of occupancy¹. Utah’s occupancy provision applies where the State Construction Code calls for that certificate⁶. Before planning your move, ask your local building department which final approvals your house needs.
