Homes with Casitas & Guest Houses in Stansbury Park, Utah
Stansbury Park sits about 35 minutes west of Salt Lake City on the south end of the Tooele Valley, and the lot sizes here are part of what makes casita and guest house properties workable. Many of the homes built around the Stansbury Lake area, Village neighborhood, and the newer Lakeside and Benson Mill developments sit on quarter-acre to half-acre parcels — enough room for a detached guest unit, a converted garage suite, or a mother-in-law casita without crowding the main house. Tooele County's accessory dwelling rules are generally more flexible than what you'll see in Salt Lake County, and that's drawn buyers who need housing for aging parents, adult kids saving for their own place, or a rentable unit to help offset a mortgage at today's rates.
The buyer pool for these properties tends to split three ways: multigenerational families, remote workers who want a separate office/studio building, and investors eyeing mid-term rentals for travel nurses at Mountain West Medical Center or contractors working at the Tooele Army Depot and the new data center projects. Pricing typically runs a premium of $50K–$120K over a comparable single-residence home, depending on whether the casita has its own kitchen, separate utilities, and a private entrance. Square footage on guest units around here ranges from roughly 400 to 1,200 sq ft.

Common questions
About homes with casitas & guest houses in Stansbury Park.
Does Tooele County allow short-term rentals in Stansbury Park casitas? ▾
Tooele County permits short-term rentals in some areas, but Stansbury Park itself falls under the Stansbury Park Improvement District and HOA covenants that often restrict rentals under 30 days. Mid-term and long-term rentals (30+ days) are generally allowed. Always verify with the specific subdivision's CC&Rs before assuming rental income.
Are most guest houses here permitted as legal ADUs? ▾
It varies. Some are fully permitted accessory dwelling units with separate addresses and utility meters, while others are listed as 'mother-in-law suites' or 'bonus quarters' that may not have gone through formal ADU permitting. Ask the listing agent for the certificate of occupancy and check Tooele County records before closing.
What's the typical price premium for a home with a casita in Stansbury Park? ▾
Expect to pay roughly $50,000 to $120,000 more than a comparable single-residence home in the same neighborhood. The premium widens when the casita has a full kitchen, separate entrance, and its own HVAC — features that make it function as a true second living space rather than just a bonus room.
Can the casita be financed as part of a standard mortgage? ▾
Yes. Conventional, FHA, and VA loans all allow ADUs and casitas on the same parcel, and FHA even lets you count documented rental income from the unit toward qualifying. Appraisers in the Tooele Valley are familiar with these setups, so financing usually isn't a hurdle as long as the structure is permitted.
How does Stansbury Park compare to nearby Erda or Grantsville for guest house properties? ▾
Erda has larger lots (often 1+ acre) and more rural zoning that's friendlier to detached structures, but homes run higher. Grantsville offers similar acreage at lower price points but a longer commute to Salt Lake. Stansbury Park splits the difference with smaller lots, HOA-managed amenities like the lake and golf course, and the shortest drive to I-80.
Are casita listings common in Stansbury Park? ▾
They're a smaller slice of the market — usually a handful active at any given time out of the broader Stansbury Park inventory. Because they move quickly when priced right, it's worth setting up an MLS alert if nothing on the current list fits your needs.
