Homes with Casitas & Guest Houses in Orem, Utah
Orem sits in the middle of Utah County between Provo and American Fork, with Utah Valley University driving a steady demand for flexible living space. Homes with a casita or detached guest house are less common here than in St. George or Park City, but they show up most often in the older established neighborhoods east of State Street — Cherry Hill, Sharon Park, and the foothill pockets near Cascade Elementary — where larger lots from the 1960s and 70s left room for mother-in-law additions, basement apartments with private entries, or true detached units above a garage. Newer builds on the Orem/Lindon border occasionally include attached casitas as part of multi-generational floor plans.
Buyers come to these listings for a few specific reasons: housing aging parents close to Intermountain's Orem campus and Timpanogos Regional, accommodating returned missionaries or UVU students, or generating rental income in a city where vacancy rates stay tight year-round. Orem's zoning is stricter than some Utah cities about short-term rentals, so most owners use guest houses for long-term tenants, extended family, or home offices. Lot sizes, separate utility meters, and whether the unit is legally permitted as an ADU all matter more here than the cosmetic finishes — those details change the appraisal and the rental income you can count.

Common questions
About homes with casitas & guest houses in Orem.
What's the difference between a casita, a guest house, and an ADU in Orem? ▾
A casita is usually an attached suite with its own entrance — common in newer multi-gen builds. A guest house is detached, often above a garage or in the back yard. An ADU (accessory dwelling unit) is the legal designation Orem City uses when the space has a kitchen and is permitted for separate occupancy. Only ADUs registered with the city can be legally rented.
Does Orem allow short-term rentals in a casita or guest house? ▾
Orem restricts short-term rentals (under 30 days) in most residential zones, so Airbnb-style use of a guest house is generally not permitted. Long-term rentals to a single household are allowed in registered internal ADUs. Always confirm the property's permit status and current zoning with Orem City before counting on rental income.
How much more do homes with guest houses cost in Orem? ▾
The premium typically runs $60,000 to $150,000 over a comparable home without the extra unit, depending on whether the casita is finished living space, has a full kitchen, and is legally permitted. Detached units on larger lots near the foothills carry the highest premium because the lot itself is harder to replicate.
Are the guest units usually permitted, or built without approval? ▾
It's a mix. Many older Orem homes have basement apartments or backyard units that were added decades ago without current ADU permits. Lenders and appraisers treat permitted and unpermitted units very differently, so request the building permit history from Orem City during your due diligence.
Which Orem neighborhoods have the most homes with casitas? ▾
The older east-side neighborhoods between 800 East and the foothills tend to have the most, thanks to larger lots and the multi-generational LDS family pattern. Newer subdivisions near the Lindon border and the Geneva Road redevelopment area increasingly include attached casita floor plans from builders like Ivory and Edge.
Can I use rental income from the casita to qualify for a mortgage? ▾
Sometimes. If the unit is a permitted ADU with a documented rental history, most lenders will count 75% of the rent toward your qualifying income. Unpermitted units generally cannot be used for qualification, even if they're currently rented. A lender familiar with Utah County ADU rules can tell you what will and won't count.
