Homes with Casitas & Guest Houses in Kaysville, Utah
Kaysville sits at the base of the Wasatch about 20 minutes north of Salt Lake and 10 minutes from Hill Air Force Base, which shapes a lot of what gets built and who's buying here. Casitas and detached guest houses show up most often in the older estate pockets east of Highway 89 — around Mutton Hollow, Crestwood, and the foothill lots above Fairfield Road — plus newer custom builds in East Kaysville where lot sizes still allow an accessory dwelling. The combination of larger half-acre-plus parcels, established trees, and a city government that has been reasonable about ADU permitting makes this one of the more practical Davis County markets for multigenerational setups or a private space for adult kids attending Weber State or the U.
Buyers here tend to fall into three camps: military families stationed at Hill who want housing for visiting relatives, LDS families planning for aging parents or returning missionaries, and remote workers who want a separate office or short-term rental income. Kaysville does regulate internal and detached ADUs differently, and short-term rentals under 30 days are restricted in most residential zones, so it's worth confirming intended use before writing an offer. Pricing on homes with a true legal casita typically runs $150K–$350K above comparable single-residence homes in the same neighborhood, depending on whether the guest space is attached, detached, or a finished basement apartment with a separate entrance.

Common questions
About homes with casitas & guest houses in Kaysville.
What's the difference between a casita, a guest house, and an ADU in Kaysville? ▾
In practice, locals use the terms loosely, but Kaysville City treats them differently. A casita or guest house usually means a detached secondary structure, while an ADU (accessory dwelling unit) is the legal classification — either internal (within the main home) or detached. Internal ADUs are allowed by right in most residential zones; detached units face more restrictions on lot size, setbacks, and owner-occupancy.
Can I rent out the guest house on Airbnb? ▾
Short-term rentals under 30 days are heavily restricted in Kaysville's residential zones. Long-term rentals (30+ days) of a permitted internal ADU are generally allowed if the owner lives on-site. Always verify current ordinances with Kaysville City Planning before basing a purchase on rental income projections.
Are these guest houses usually permitted and legal? ▾
Not always. A fair number of basement apartments in older Kaysville neighborhoods were built or finished without proper ADU permits. During due diligence, ask the seller for the permit history and check with the city — unpermitted units can affect appraisal, insurance, and your ability to legally rent the space.
Which Kaysville neighborhoods have the most homes with casitas? ▾
The east bench above Mountain Road, the Baer Creek area, and parts of Fruit Heights have the larger lots that accommodate detached casitas. For internal mother-in-law suites, look at newer Holmes Creek subdivisions and the Crestwood area where builders have offered ADU floor plans.
How much more do these homes cost compared to a standard Kaysville home? ▾
Expect roughly a $75K–$175K premium over a comparable home without a secondary unit. Detached, fully permitted casitas with separate utilities sit at the top of that range. Internal suites with a shared meter and entrance through the main home tend to add less.
Can financing cover a home with a guest house? ▾
Yes — conventional, FHA, and VA loans all allow properties with ADUs, and recent Fannie Mae guidelines let you count a portion of ADU rental income toward qualifying. The appraiser will need comparable sales with similar secondary units, which can be tight in Kaysville, so work with a lender familiar with Davis County ADU appraisals.
