Homes with Casitas & Guest Houses in Apple Valley, Utah
Apple Valley sits in the southeast corner of Washington County at about 3,000 feet of elevation, roughly 20 minutes from Hurricane and a half-hour drive to the south entrance of Zion National Park. The town runs on large lots, big sky, and views of Smithsonian Butte and the Vermilion Cliffs — the kind of setting where a detached guest house actually makes sense because there's room to build one without crowding the main residence. Casitas and guest quarters here serve a mix of buyers: retirees hosting visiting kids and grandkids for weeks at a time, families running a multi-generational household, and Zion-bound buyers who want private space for long-term guests. Summers run hot (mid-90s to low 100s in July) but evenings cool off thanks to elevation, and winters are mild with occasional dustings of snow.
Most casita properties in Apple Valley fall into one of three buckets: custom homes on 1-5 acres with fully detached guest houses, newer subdivision builds in Big Plains and surrounding developments with attached casita suites, and older manufactured or modular homes with permitted secondary structures. Well and septic are common outside the town core, and a second dwelling often means a second septic system, so review the disclosures carefully. Short-term rental rules are stricter than in St. George, but long-term ADU use is generally workable when the structure is properly permitted.

Common questions
About homes with casitas & guest houses in Apple Valley.
What's the difference between a casita and a guest house in Apple Valley listings? ▾
In Washington County MLS data, a casita is usually an attached or detached suite with its own entrance, bathroom, and often a kitchenette — common in southern Utah desert builds. A guest house is typically a fully separate structure with a full kitchen, sometimes on its own septic or meter. Both show up under accessory dwelling fields, so check the remarks for whether it's permitted as a legal ADU.
Can I rent out a casita or guest house in Apple Valley as a short-term rental? ▾
Apple Valley Town has its own ordinances, and short-term rentals are restricted in most residential zones — closer to how Hurricane and Toquerville handle it than how St. George does. Long-term rentals of an ADU are generally allowed if the structure was permitted. Always verify with the town offices before assuming nightly rental income.
Are casita properties in Apple Valley typically on well and septic? ▾
Many are. Apple Valley sits at around 3,000 feet on the way to Zion, and large-lot properties on Smithsonian Way, Mustang, and the east-side acreage parcels often use private well and septic rather than municipal systems. A second dwelling can require a separate septic system or an engineered upgrade, so factor that into your offer.
What price range do homes with guest houses run in Apple Valley? ▾
Expect a wide spread. A modest manufactured home with a casita on an acre can list in the upper $300s to mid $400s, while custom homes with detached guest quarters on 2-5 acres regularly cross $700K and into the low seven figures. Acreage, views toward Zion and Smithsonian Butte, and water shares drive most of the price difference.
Why are casitas so common in this part of Washington County? ▾
Multi-generational living is normal here, and Apple Valley draws retirees, snowbirds, and families wanting room for visiting kids and grandkids near Zion. Lot sizes are generous compared to St. George or Washington City, which makes detached guest quarters practical without variances. Builders in Big Plains and the surrounding subdivisions have been adding them as standard floorplans for years.
How many homes with casitas or guest houses are usually on the market here? ▾
Apple Valley is a small town — inventory across all property types typically runs in the dozens, not hundreds. At any given time you might see five to fifteen active listings advertising a casita, guest house, or mother-in-law setup. The active list below reflects current MLS data.
