Homes with Casitas & Guest Houses in Plain City, Utah
Plain City sits in northwest Weber County, about 10 minutes west of Ogden and roughly 45 minutes north of Salt Lake City International. It's still genuinely rural in character — lots tend to run larger than what you'll see in Roy or South Ogden, many parcels carry irrigation water rights, and the zoning across much of the city allows for accessory structures that wouldn't fly in a tighter subdivision. That's a big reason casitas and detached guest houses show up here more often than in neighboring Weber County cities. Multi-generational families wanting a private space for aging parents, remote workers needing a separate office, and buyers who want a legal long-term rental on the same parcel all gravitate to Plain City for exactly this reason.
Pricing on properties with a secondary dwelling in Plain City typically runs from the upper $600s for a modest main home with a converted shop apartment up past $1.2M for newer builds on an acre or more with a fully permitted detached casita. Before writing an offer, it's worth confirming with Plain City's planning department whether the second unit is permitted as an ADU, a guest house (no kitchen), or a legal nonconforming structure — the distinction affects financing, rental income potential, and resale. Septic capacity and culinary water connections matter too on the larger lots west of 4700 West. Browse the active listings below to see what's currently on the market.

Common questions
About homes with casitas & guest houses in Plain City.
Are detached casitas and guest houses legal in Plain City? ▾
Plain City allows accessory dwelling units and guest houses in most residential zones, but the specific rules depend on lot size, zone, and whether the second unit has a kitchen. A guest house without a stove is treated differently than a full ADU. Always confirm the structure's permitted status with Plain City's planning office before closing.
Can I rent out the casita as a long-term or short-term rental? ▾
Long-term rentals of a legal ADU are generally allowed on parcels that meet the zoning and parking requirements. Short-term rentals (under 30 days) are more restricted in Plain City and aren't permitted in most residential zones, so don't count on Airbnb income unless you've verified the address qualifies.
How does a casita affect financing and appraisal? ▾
Conventional and FHA appraisers will give value to a permitted ADU, and FHA now allows a portion of projected ADU rent to count toward qualifying income on some loans. Unpermitted second units are typically appraised as bonus square footage or storage, which can leave a gap between list price and appraised value.
What's the price difference between a Plain City home with a guest house versus without? ▾
On comparable lots, a permitted detached casita or guest house usually adds $80,000 to $200,000 in value depending on size, finish level, and whether it has a full kitchen. Converted shop apartments on acreage parcels tend to land at the higher end because the buyer also gets the outbuilding itself.
Do these properties usually sit on larger lots? ▾
Yes. Most Plain City homes with a casita or detached guest house are on a quarter-acre or larger, and many sit on a half-acre to a full acre west of 4700 West where agricultural zoning is more common. Smaller subdivision lots in the older grid near 2600 North occasionally have attached mother-in-law setups instead.
Is septic or city sewer more common on these properties? ▾
It depends on location. Homes inside the older central grid are typically on Plain City sewer, while many of the larger acreage parcels on the west and south edges are still on septic. A septic system's drainfield capacity can limit whether a second unit is approvable, so request the septic permit and recent inspection during due diligence.
