This filter too narrow?
Browse every Washington listing, or slide sideways: single story, acreage, new construction.
A true second living space is a smaller slice of the market, so the grid can run lean some weeks. Tell me how you want to use the extra space, a guest suite, a home office, multi-generational living, and I will watch for the homes whose casita actually fits.

The local read
What a casita or ADU really is in Washington.
On a Washington listing you will see this space called a few things: a casita, a guest house, a mother-in-law suite, a detached suite, or an accessory dwelling unit, the ADU acronym. They describe a second, more self-contained living space tied to a single home. It might be an attached wing with its own entrance and a small kitchenette, a finished space over a deep garage, or a freestanding little building set off the main house. The common thread is flexibility: a place for visiting family, a quiet home office away from the main house, a multi-generational arrangement, or a hobby and creative space. It is flexible square footage, and that is how to think about it.
Utah opened the door to internal accessory dwellings in a broad way in recent years, which generally allows an owner to create a separate living unit inside their primary home, subject to limits. Detached casitas, the freestanding kind, are a different question and depend on the parcel's zoning, the lot, setbacks, and what Washington City allows there. That distinction matters, because a listing might call a finished basement room a guest suite or call a detached building a casita, and the rules that apply to each are not the same. The honest move is to treat any listing language as a starting point and verify the unit is actually permitted and legal for the use you have in mind.
Where do these turn up? The larger lots give a detached casita room to sit, so the bigger parcels at Oak Grove Meadows and the east-side customs at Canterwood Estates are natural places to look. The bench customs at Washington Bench and ridge homes in Coral Canyon sometimes design a guest suite into the floor plan, and the newer production builders across Stucki Farms and Long Valley offer next-gen or multi-generational plans with a connected suite.
On price, a home with a real casita usually carries the cost of that extra finished space, so these tend to sit a little higher than a comparable home without one, across the Washington range that has recently centered near the $560,000 median. The custom homes with detached casitas reach toward the top of the market. Earlier in the process than browsing? Start with the Washington guide or the communities index. When a listing's setup looks right, call and I will help you sort what is permitted from what is simply described.
What counts as a casita or ADU here
-
Attached suite: a wing of the main home with its own entrance, a bedroom and bath, and often a kitchenette. Connected to the house but more private. Common in next-gen production floor plans.
-
Detached casita: a freestanding small building separate from the main home. The most flexible, and the one most dependent on lot, setbacks, and what the zone allows. Verify it is permitted.
-
Above-garage or basement suite: finished space over a deep garage or in a walkout level, set up as a self-contained room. Read whether it is a true separate unit or simply a finished bonus room.
-
Flexible use, not income framing: think of the space as room for guests, a home office, or extended family. Whether any other use is allowed is a zoning question to confirm with the city, not an assumption.
The local map
Where casitas and suites show up.
A second living space is a feature, not a neighborhood, but a few patterns hold in Washington: detached casitas want larger lots, and attached suites ride with newer plans. Here is where to look.
Oak Grove Meadows
Third-acre to half-acre and larger lots give a detached casita the room it needs. The bigger the parcel, the more workable a freestanding guest building becomes, subject to setbacks and what the zone allows.
Canterwood Estates
Half-acre to full-acre custom homesites on the east side, where a custom build can be designed around an attached or detached suite from the start. Custom land is where the most ambitious casitas land.
Washington Bench
Elevated custom and semi-custom homes on larger lots. Some floor plans here design in a guest suite or a casita with its own entrance, often with a view that makes the extra space pleasant to live in.
Next-gen production plans
Builders across Stucki Farms and Long Valley sometimes offer a multi-generational floor plan with a connected suite, its own entry, and a kitchenette, built right into a production home.
Coral Canyon ridge customs
Custom homes on the east-side red rock occasionally include a guest casita as part of a larger build. Read the listing to learn whether it is a permitted separate unit or a finished bonus space.
The verification step
Wherever the casita sits, the same step applies: confirm with Washington City that the unit is permitted and legal for how you intend to use it. A listing's label is a description, not an approval.
Before you tour: what to actually check
Attached or detached: an attached suite and a freestanding casita follow different rules. Figure out which one the listing is describing before you assume what is allowed.
Permitted and legal: confirm with Washington City that the unit is permitted for the use you intend. A finished room and an approved accessory dwelling are not the same thing.
Kitchen and utilities: check whether the space has a kitchenette, its own bath, and how it is metered for power and water. These details define how self-contained it really is.
Entrance and privacy: look at whether the suite has a separate entrance and how it connects to the main home. That shapes how it works for guests or extended family.
Lot and setbacks: for a detached casita, the lot size and the setbacks decide what is even possible. The larger lots on the edges give the most room.
Heating and cooling: ask how the casita is conditioned. A separate or zoned system handles a hot Washington summer better than a window unit fighting the heat.

Quick answers
Casita and ADU shopping, answered.
It is a second, more self-contained living space tied to a single home. On listings you will see it called a casita, a guest house, a mother-in-law suite, a detached suite, or an accessory dwelling unit. It can be an attached wing with its own entrance, a finished space over a garage, or a freestanding building. The point is flexible square footage, room for guests, a home office, or multi-generational living.
Utah law broadly allows internal accessory dwellings inside a primary home, subject to limits, while detached casitas depend on the parcel's zoning, the lot, and what Washington City permits there. Because the rules differ between an attached unit and a freestanding one, the honest step is to confirm with the city that the specific unit is permitted and legal for the use you have in mind, rather than relying on the listing's label.
An attached suite is part of the main home, usually with its own entrance and sometimes a kitchenette, and is common in next-gen production floor plans. A detached casita is a freestanding building separate from the house, which is the more flexible setup but the one most tied to lot size, setbacks, and zoning. Knowing which one a listing describes tells you which set of questions to ask.
Detached casitas want room, so the larger lots at Oak Grove Meadows and the custom homesites at Canterwood Estates are natural places to look, along with bench customs at Washington Bench. Attached and next-gen suites turn up in newer production plans across Stucki Farms and Long Valley. The live listings above are the honest count of what is available right now.
Do not assume that from a listing. Whether any particular use beyond family or guests is allowed is a zoning question, and short-term nightly use in Washington City is a separate matter governed by the city's rental overlay. Confirm the permitted uses with Washington City in writing before you count on anything, and see the short-term rental page for how nightly rules work here.
Tell me how you plan to use the space and I will read the listings rather than trust the label, flag the homes with a genuine attached suite or detached casita, and help you verify the unit is permitted before you tour. Pair that with a pre-approval, since homes with a true second living space are a smaller slice of the market and tend to draw interest.
