Garage Conversion Cost in Utah

In response to Utah's growing housing shortage, state laws like HB 82 and SB 174 have streamlined the process for 'Internal Accessory Dwelling Units' (IADUs), making garage conversions a highly viable way to add living space or rental income. Whether you are in the high-desert climate of St. George or the snow-heavy Wasatch Front, converting a garage requires navigating specific local zoning, rigorous energy codes, and unique seismic considerations. This guide breaks down everything from parking replacement rules in Salt Lake City to the mandatory R-values needed to keep your new space comfortable year-round.

Frequently Asked Questions

Do I need a building permit for a garage conversion in Utah?

Yes. A building permit is mandatory for any garage conversion involving structural changes, electrical, plumbing, or mechanical work. Failure to obtain one can result in fines and issues when selling your home.

How much does a garage conversion cost in Utah in 2025?

A basic 'finished room' conversion typically costs between $15,000 and $25,000. A full ADU conversion with a kitchen and bathroom ranges from $45,000 to $75,000 depending on the finishes and utility hookup complexity.

Can I have separate utility meters for the converted space?

In most Utah jurisdictions, ADUs are required to share utility connections with the primary house. While you can install secondary check-meters to monitor usage, the main billing remains unified.
