Can I Build an ADU (Accessory Dwelling Unit) in Utah?
ADU permit requirements. State law, internal vs. detached, basement apartments, and impact fee waivers.
Often yes — many states now require cities to allow at least internal ADUs.
Utah-specific rules
Adopted code: 2021 IRC (habitable-space and egress requirements), adopted statewide under Utah Code § 15A-2-103.
Utah HB 82 (2021 General Session, "Single-Family Housing Modifications"): in any single-family residential zone, requires municipalities and counties to classify qualifying internal accessory dwelling units as a permitted land use, and limits the restrictions a city or county may impose on them.
Sources: Utah State Construction and Fire Codes Act (Title 15A), H.B. 82, 2021 General Session — Single-Family Housing Modifications (enrolled bill)
State Law May Require It
A growing number of states have passed laws requiring cities to allow at least internal ADUs (within the existing footprint of the home — basement apartments, above-garage units, etc.). Many cities also allow detached ADUs, though rules on size and placement vary. Check whether your state has an ADU-enabling law before assuming your city can simply say no.
Types of ADUs
Internal ADUs include basement apartments, converted attic space, and attached additions. Detached ADUs include backyard cottages, converted garages, and purpose-built accessory structures. Each type has different permit requirements and setback rules.
Key Requirements
Most ADUs need: a separate entrance from the primary dwelling, adequate parking (usually one additional off-street space), fire separation (1-hour rating for internal ADUs), and compliance with all building codes for habitable space. Basement ADUs require egress windows in every bedroom.
Reduced Impact Fees
Some states limit impact fees for ADUs, making them cheaper to permit than a full second dwelling. Many cities waive or significantly reduce impact fees for ADUs. Ask your city about current fee schedules — this can save thousands of dollars.
In many states you can build an ADU thanks to state law requiring cities to allow it. Internal ADUs are the easiest path. Start by checking your state's ADU law and your city's specific ADU ordinance.
