Homes with Casitas & Guest Houses in Washington Terrace, Utah
Washington Terrace sits between Ogden and South Ogden along Wall Avenue and Adams Avenue, a working-class Weber County community built largely in the 1950s and 60s on generous quarter-acre and half-acre lots. Those bigger parcels are exactly why casitas and detached guest houses show up here more than in newer Weber County subdivisions — there's actual side and back yard room to add a small structure without crowding the main house. Sellers who've added a guest house often did it for aging parents, adult kids, or as a rental unit to help with the mortgage, since Weber State University and Hill Air Force Base both pull steady tenant demand from Ogden-area properties.
Buyers shopping this niche in Washington Terrace are usually solving a specific problem: multigenerational living, a home office separate from the family noise, or a mortgage-helper unit that can rent for $900-$1,400 a month depending on size and finish. Because the city's zoning is a patchwork of R-1 and R-2 lots, not every property can legally add or keep a detached unit as a rental — that detail matters more here than the finish level of the casita itself. Weber County's building permit history is public record, so it's worth confirming a guest house was permitted before assuming it's income-ready. Browse the active listings below to see which Washington Terrace properties currently have a casita or guest house on the lot.

Common questions
About homes with casitas & guest houses in Washington Terrace.
Can I legally rent out a casita or guest house in Washington Terrace? ▾
It depends on the lot's zoning designation and whether the structure was permitted as an accessory dwelling unit. Washington Terrace has both R-1 and R-2 zones, and rules on renting a detached unit differ between them, so check with the city planning office before assuming a listing's guest house is a legal rental.
Were these guest houses built with permits? ▾
Not always — this is an older city with a lot of owner-added structures from past decades, some done without permits. Weber County keeps permit records that a buyer's agent can pull, and it's worth doing before closing if the rental income is part of your plan.
How much does a casita add to the price of a home here? ▾
Expect a premium of roughly $20,000 to $50,000 over a comparable home without one, depending on the guest house's size, whether it has its own kitchen and bathroom, and its condition. A fully finished, permitted unit with separate utilities sits at the higher end of that range.
Do these guest houses have their own utilities? ▾
Some do, some share a meter with the main house — it varies property by property since most were owner-built rather than part of an original subdivision plan. If separate utility metering matters for a rental setup, ask specifically, since listing photos rarely make this clear.
Are lots big enough for a guest house common in Washington Terrace? ▾
Yes, more common than in newer Ogden-area subdivisions. Many original lots here run a quarter-acre to half-acre, giving enough backyard depth for a detached structure, which is a big reason this city has more of these properties than neighboring newer developments.
What's a realistic use case for a casita in this city? ▾
The most common buyers are families wanting a parent or adult child nearby but separate, and owner-occupants using the extra unit to offset a mortgage with rental income tied to Weber State students or Hill AFB personnel. Both uses show up regularly among active listings here.
