Summary
Salt Lake City lets pre-1995 garage-to-living-space conversions on single-family and two-family lots become legal only after a building permit, a life-safety inspection, and replacement of any lost driveway parking spaces.
Garages attached to single-family and two-family residential structures converted to residential uses before April 12, 1995...may be legalized by complying with the following requirements: 1. The property owner shall obtain a building permit for all building modifications...and the city shall inspect the conversion for substantial compliance with adopted life safety regulations. 2. The driveway leading to the converted garage shall not be removed without replacing the same number of parking spaces...3. Parking on the driveway in the front yard is restricted to passenger vehicles only.

Full Breakdown
Under Salt Lake City Code § 21A.44.110.D, garages attached to single-family and two-family homes that were converted to living space before April 12, 1995 can be legalized rather than torn out. The owner must pull a building permit for the conversion work, and the city inspects for substantial compliance with adopted life-safety code. Any driveway serving the converted garage stays in place unless the owner replaces the lost parking spaces elsewhere on the lot, and front-yard driveway parking is limited to passenger vehicles only.
Violations & Fines
Skipping the building permit and life-safety inspection, or removing the driveway without replacing the required parking spaces, means the garage conversion doesn't qualify for legalization and remains a code violation.
