Homes with Casitas & Guest Houses in Midvale, Utah

Midvale allows internal accessory dwelling units citywide under state law, and detached ADUs are permitted in specific zones with conditional approval. Always confirm the unit on a given listing is permitted and on file with the city — many older homes have basement apartments that were finished without permits, which affects financing and resale.

Long-term rentals of a legal ADU are allowed if the owner occupies one of the units. Short-term rentals (under 30 days) are restricted in most residential zones. Verify the specific rental status with Midvale Community Development before counting on rental income.

A permitted, legal ADU with its own kitchen and bath usually adds appraised value and can sometimes count toward qualifying income on FHA and conventional loans. An unpermitted basement apartment generally won't — appraisers list it as bonus living space rather than a separate unit, so the lift on value is smaller.

East Midvale around 7800 South and the older streets near Union Park have the larger lots that accommodate detached structures. Bingham Junction and the newer subdivisions west of State Street more often have attached mother-in-law suites built into the main house.

A Midvale home with a legal, separately accessed guest unit typically runs $50,000-$150,000 above a comparable single-unit home on the same street, depending on the size, finish level, and whether utilities are separately metered. Unpermitted setups command much less of a premium.

Inventory is thin — Midvale is a small city of about 36,000, and qualifying properties usually number in the single digits at any given time. The list below shows what's currently active, and it pays to set up an alert since these move quickly when priced right.
