Homes with Casitas & Guest Houses in Riverton, Utah
Riverton sits in the southwest corner of Salt Lake County, roughly 20 miles from downtown Salt Lake City and tucked between Bangerter Highway and the Wasatch foothills. It's a family-oriented city of about 45,000 residents where multigenerational living has quietly become one of the dominant forces shaping what buyers want from a home. Casitas and detached guest houses in Riverton carry real practical weight: they give aging parents a private entrance and a yard to call their own without anyone leaving the family property, or they generate rental income that can offset a mortgage in a market where the median single-family home price has hovered in the $550,000–$650,000 range. Because lot sizes in Riverton run larger than in neighboring South Jordan or Herriman — many neighborhoods platted in the 1990s sit on quarter-acre-plus lots — there's genuine room for a detached structure rather than just an attached in-law suite squeezed inside the main footprint.
What separates a true guest house from a simple basement apartment matters both legally and practically. Salt Lake County's accessory dwelling unit (ADU) ordinance governs what can be permitted, rented, and occupied independently, so understanding how a property is permitted before you write an offer is essential. Some Riverton casitas come fully permitted with separate metering and private exterior access; others function as flex spaces that stop short of full ADU status. Knowing the difference affects financing, insurance, and what you can charge a tenant.

Common questions
About homes with casitas & guest houses in Riverton.
Are casitas and guest houses legal as rentals in Riverton? ▾
Riverton allows accessory dwelling units under its municipal code, but most permitted ADUs require the owner to live on the property and meet parking, setback, and utility separation rules. Short-term rentals (under 30 days) face additional restrictions. Always confirm the unit is permitted and check current city ordinances before counting on rental income.
What's the typical price difference between a Riverton home with a casita versus without? ▾
Expect to pay roughly $75,000 to $150,000 more for a comparable home with a legitimate, permitted guest house or casita. The premium depends heavily on whether the unit is detached, has its own kitchen and utilities, and whether it's been finished to the same quality as the main home.
How common are detached guest houses in Riverton compared to attached casitas? ▾
Detached guest houses are less common and usually show up on the larger half-acre-plus lots on the west side of town and in older horse-property areas. Attached casitas, basement apartments with private entrances, and garage-conversion ADUs are far more typical in the standard subdivisions built since 2000.
Do casitas in Riverton usually have separate utility meters? ▾
It varies. Newer purpose-built ADUs often have separate electric meters, but many converted basement units and older guest quarters share utilities with the main house. If utility separation matters for rental accounting or tenant billing, ask for specifics during showings and review the seller's disclosures.
Which Riverton neighborhoods are best for finding homes with guest quarters? ▾
Hi-Country Estates, Rose Canyon, and the acreage parcels along 13400 South and 12600 West tend to have the most detached guest houses thanks to larger lots. For attached casitas and finished basement apartments, look in newer developments around Mountain View Corridor and the Riverton Ranches area.
Can I use rental income from a casita to qualify for my mortgage? ▾
Sometimes. Lenders generally require the unit to be legally permitted as an ADU and may want a lease in place or a rental schedule from an appraiser. FHA and conventional guidelines differ, so talk with your loan officer early — an unpermitted basement apartment usually won't count toward qualifying income.
