Garage conversion rules in Salt Lake County, UT — sometimes called garage-to-ADU or accessory living unit conversions — govern permits, ceiling height, egress, and parking replacement.
Garage conversions to habitable space in unincorporated Salt Lake County require building permits and Utah Residential Code compliance. If converted to an ADU, Chapter 19.15 rules apply including lot size minimums and parking requirements. Certificate of occupancy required before habitation.
Utah SB 164 (2021) requires cities to allow internal ADUs on owner-occupied lots, which may include garage conversions. Salt Lake County may allow conversions with building permits meeting habitable space code: ceiling height, ventilation, egress, insulation, electrical, plumbing. Replacement parking may be required depending on city code. Insulation and heating requirements significant due to Utah’s cold winters. HOAs may still restrict garage conversions.
Unpermitted conversion: building code enforcement. Must bring to code or restore. Safety violations: immediate correction.
