Homes with Casitas & Guest Houses in Hyrum, Utah
Hyrum sits at the south end of Cache Valley, about 10 minutes from Logan and a straight shot to Hyrum State Park and the Blacksmith Fork Canyon trailheads. It's a small town of around 9,000 with a working agricultural footprint, which is why so many properties here sit on quarter-acre to multi-acre lots — the kind of parcels that actually have room for a detached casita, mother-in-law apartment, or guest house above a shop. Buyers looking for accessory dwellings in Hyrum are usually one of three types: families housing aging parents, USU faculty or grad-school households wanting a private space for visiting relatives, or homeowners who want long-term rental income in a market where Logan-area rents have climbed steadily.
Cache County allows accessory dwelling units under specific zoning conditions, and Hyrum's city code permits internal ADUs in most residential zones with owner-occupancy requirements; detached guest houses generally need larger lots and proper permitting. That matters because not every "casita" on the MLS is a legal, separately-metered second unit — some are bonus rooms or finished outbuildings without kitchens. Price ranges run wide: a home with a finished basement apartment might start in the mid $400s, while properties with a true detached guest house on acreage often sit in the $700s to low $900s. Winters here are cold and snowy (Cache Valley inversions are real), so insulated, properly heated secondary structures hold their value. Browse the active listings below to see which Hyrum homes currently include a casita or guest house setup.

Common questions
About homes with casitas & guest houses in Hyrum.
Are detached guest houses legal in Hyrum? ▾
Hyrum allows accessory dwelling units under the city's zoning ordinance, but detached guest houses typically require a larger lot, proper setbacks, and a building permit. Owner-occupancy of the primary residence is generally required. Always confirm the specific zone (R-1, R-2, A-1, etc.) and whether the existing structure was permitted as a dwelling before closing.
What's the price difference between a Hyrum home with a casita versus without? ▾
Expect to pay roughly $75,000 to $150,000 more for a comparable home that includes a legal, finished accessory unit. The premium depends on whether the casita has its own kitchen, separate utilities, private entrance, and square footage. Detached guest houses on acreage carry the highest premium.
Can I rent out the guest house on Airbnb in Hyrum? ▾
Short-term rentals are restricted in most Hyrum residential zones and typically require a conditional use permit if allowed at all. Long-term rentals (30+ days) of a permitted ADU are more straightforward. Check current Hyrum City code and talk to the planning department before counting on rental income.
Do casitas in Hyrum usually have separate utility meters? ▾
Most internal ADUs share meters with the main house, while detached guest houses on larger parcels sometimes have separate power and gas service. Separately metered units make rental accounting cleaner and tend to appraise higher. Listing remarks will usually note metering, but verify with the utility provider.
Are these properties a good fit for multigenerational living? ▾
Yes — that's actually the most common buyer profile in Hyrum. Cache Valley has strong LDS family roots and a culture of housing aging parents nearby, so casita and mother-in-law setups move quickly when priced right. Single-level guest quarters with no-step entries are especially in demand.
How many Hyrum homes with casitas or guest houses are typically on the market? ▾
Inventory is thin — usually a handful at any given time across all of Hyrum. Cache Valley as a whole sees more options if you expand the search to Nibley, Providence, or Wellsville. Setting up an MLS alert is the most reliable way to catch new listings the day they hit the market.
