Research ADU Regulations in Utah by City

Implementing an ADU as a homeowner you must fully understand the building codes that your property is subject to comply with as you build your ADU. You cannot legally implement a secondary living space on your property with out meeting the code requirements established by your city or county government.

The First Step In Creating Your ADU in Utah

All accessory dwelling units, added to the property of an existing house, are subject to the local laws and ordinances that are established by city codes within each county in Utah. If your city or town doesn’t have building codes for ADUs then you need to check with your county to learn the building codes for ADUs in your area.

ADU Utah is providing this page as the starting point to help you find the relevant laws and code requirements for your property located in Salt Lake, Davis, Weber, Utah, and Summit counties. Each county has a list of cities you can select to locate a direct link to the code relevant to ADU implementation requirements. Of course, if you have any questions, click here to contact us.
