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.
