Choose your city

In Utah, the permitting process for accessory dwelling units involves adherence to state building codes and the specific land use regulations established by individual municipalities, such as West Jordan, St. George, and Sandy. The state's climate, with its significant temperature fluctuations and varying precipitation, necessitates careful material selection and construction sequencing to ensure structural integrity and energy efficiency. Permit costs are directly influenced by the complexity of your ADU design, the thoroughness of the submitted architectural and engineering plans, and the fee structure of the local permitting authority.

Common questions

How big can an ADU be in Utah?

The maximum size of an ADU in Utah is determined by local municipal zoning ordinances, not a statewide cap. While state law encourages ADU development, specific regulations regarding maximum square footage, height, and lot coverage are set by each local government. Consulting the planning department in your area, such as West Jordan or St. George, is essential for precise details.

What are the downsides of ADUs?

Potential downsides of ADUs can include increased demand on existing utility infrastructure, potential impacts on neighborhood character if not well-integrated, and the owner's responsibility for managing a rental property. The initial capital investment for construction is also a significant consideration. Thorough planning and adherence to local building codes can effectively mitigate these concerns.

What is the cheapest way to build an ADU?

The most economical method for ADU construction often involves utilizing pre-designed plans or modular building systems, which can reduce custom design fees and accelerate the build timeline. Opting for simpler architectural designs with standard material specifications, and minimizing extensive site modifications or complex utility connections, also contributes to lower overall project expenditures.

What does ADU stand for?

ADU is an acronym for Accessory Dwelling Unit. These are secondary housing units located on the same property as a primary single-family home. They can be attached to the main house, such as a basement or attic conversion, or be a detached structure like a backyard cottage, offering flexible housing solutions in communities like West Jordan and Sandy.

Are ADUs allowed in Utah?

Yes, ADUs are permitted in many Utah municipalities, with state laws increasingly supporting their development to address housing needs. However, specific regulations and zoning requirements vary by city and county. It is crucial to review the local ordinances for your specific location, including St. George, to ensure compliance.

What drives ADU permit costs in Utah?

The financial implications of an ADU permit in Utah are primarily driven by the fees established by the local jurisdiction, the complexity and completeness of the submitted architectural and engineering plans, and the number of required inspections by the building department. More elaborate ADU designs in areas like Sandy will typically incur higher administrative and review charges.
