Homes with Casitas & Guest Houses in Charleston, Utah
Charleston sits on the south shore of Deer Creek Reservoir in Wasatch County, tucked between Midway and the mouth of Provo Canyon. It's one of the smallest incorporated towns in Utah, with large lots, agricultural setbacks, and direct views across the water to Mount Timpanogos. That combination — acreage, rural zoning, and proximity to Heber, Midway, and the Park City resorts — is exactly why casitas and detached guest houses show up more often here than in tighter Wasatch Front suburbs. Buyers want room for visiting family during ski season, a private suite for aging parents, or a long-term rental that helps offset the carrying cost of a second home.
Most Charleston properties with a secondary dwelling fall into one of three buckets: newer custom builds in subdivisions off River Road and Center Creek Road with attached casita wings, older homesteads on an acre or more where the original farmhouse has been converted into a guest cottage, and luxury estates near the reservoir with fully detached carriage houses above oversized garages. Climate matters here too — Charleston sits at roughly 5,500 feet, so guest structures need real insulation, frost-protected plumbing, and heated walkways if you want comfortable year-round use. Short-term rental rules are stricter than in Midway, so verify zoning before banking on nightly income. Browse the active listings below to see what's currently available, and reach out if you'd like help separating true permitted ADUs from converted bonus rooms.

Common questions
About homes with casitas & guest houses in Charleston.
What's the difference between a casita and a guest house in Charleston listings? ▾
In Wasatch County MLS data, 'casita' usually means a detached or attached secondary suite without a full kitchen, while 'guest house' typically refers to a fully self-contained dwelling with its own kitchen, bath, and separate entrance. Charleston listings use both terms loosely, so always check the floor plan and whether the second unit has a stove and full plumbing before assuming it can function as a rental.
Can I legally rent out a casita or guest house in Charleston? ▾
Charleston Town is small and primarily residential, with stricter short-term rental rules than nearby Midway or Heber. Nightly rentals are generally not permitted outside of approved zones, but long-term rentals to a tenant or family member are typically allowed. Confirm current zoning with Wasatch County and the Town of Charleston before counting on rental income.
Why are casitas and guest houses common around Charleston? ▾
The area sits next to Deer Creek Reservoir and draws second-home owners, multigenerational families, and visiting skiers heading to Deer Valley and Park City about 25 minutes away. Many lots are a half-acre or larger, which leaves room for a detached structure, and builders in Red Ledges-adjacent and Charleston-proper subdivisions often include guest quarters as a standard option.
What price range should I expect for a Charleston home with a guest house? ▾
Most homes with a true detached guest house in Charleston list from the mid $1.2M range up to $4M+, depending on acreage, views of Mount Timpanogos, and proximity to the reservoir. Attached casita floor plans on smaller lots can occasionally come in under $1M, but inventory at that level is thin.
Do guest houses count as ADUs for financing purposes? ▾
Lenders treat a permitted, self-contained guest house differently than a non-conforming bonus room. If the structure has its own address, utilities, or rental history, an appraiser may include projected rental income, which helps with qualification. Bring the permit history and any rental records to your lender early in the process.
How many Charleston homes with casitas or guest houses are typically on the market? ▾
Charleston is a small town of roughly 500 residents, so active inventory with a true secondary dwelling usually runs between two and eight listings at any given time. The list below shows what's currently active in the MLS, and turnover can be slow, so setting up a saved search is worthwhile.
