Homes with Casitas & Guest Houses in Roy, Utah
Roy sits in the heart of Weber County, wedged between Ogden and Clearfield along the Wasatch Front, where a $350,000–$450,000 price point still gets you a legitimate yard — and in some cases, enough square footage to include a detached casita or guest house on the same parcel. That extra structure carries real practical value here. Hill Air Force Base is less than three miles from Roy's southern edge, which means the local rental market is consistently fed by military personnel, contractors, and civilian employees rotating in and out on 12-to-36-month assignments. Homeowners with a legal accessory dwelling unit or detached guest house regularly offset $900–$1,400 per month in mortgage costs by renting to base tenants, making the premium paid for that second structure one of the faster-returning investments in northern Utah.
Beyond the income angle, multi-generational living is genuinely common in Roy's tight-knit community, where extended families — including large Latter-day Saint households — often want grandparents or adult children close but not under the same roof. A casita solves that without buying two separate properties. Weber County zoning and Roy City code do regulate accessory dwelling units, so buyers need to confirm whether an existing guest house is permitted and whether a kitchen qualifies as a full secondary unit or a studio-style space. An experienced local agent can pull permit history before you make an offer. Browse the active listings below to see what's currently available in Roy.

Common questions
About homes with casitas & guest houses in Roy.
What's the difference between a casita, a guest house, and an ADU in Roy? ▾
In Roy, a casita usually means a small attached or semi-attached living space — sometimes a converted garage or a wing with its own entry. A guest house is detached, sitting separately on the lot. An ADU (accessory dwelling unit) is the legal zoning term and can be either internal (inside the main home) or external. Utah's 2021 internal ADU law requires cities to allow internal units in owner-occupied homes, but detached units still need local approval.
Can I legally rent out a casita or guest house in Roy? ▾
Internal ADUs are allowed by state law if the owner lives on-site, but Roy requires registration and the unit must meet building and fire code. Detached guest houses are more restricted and often can only be used by family members, not rented to the public. Always confirm with Roy City's planning department before counting on rental income.
How much extra do homes with second living spaces cost in Roy? ▾
Expect to pay roughly $40,000 to $90,000 more than a comparable single-unit home, depending on whether the second space has a full kitchen, separate utilities, and a private entrance. Permitted, legally rentable units carry the biggest premium because they appraise as income property.
Are these properties common in Roy or hard to find? ▾
They show up regularly but aren't abundant — usually a handful of active listings at any time. Older homes near 1900 West and the neighborhoods around Roy High School tend to have more basement apartments and detached shops converted to living space than the newer subdivisions on the west side.
Do Hill AFB buyers use VA loans on homes with guest houses? ▾
Yes, and VA loans can finance properties with an ADU as long as the home appraises as a single-family residence and the second unit doesn't make it function as a duplex. Rental income from the second space generally can't be counted toward qualifying on a VA loan, but it can offset your monthly payment after closing.
What should I check during inspection on a home with a casita? ▾
Look closely at separate electrical subpanels, plumbing tie-ins, heating source for the second unit, and whether the kitchen and bath were permitted. Many Roy homes have informally finished basements or garage conversions that work fine but were never inspected — that affects insurance, resale, and your ability to rent it later.
