Newest first
The newest ADU and casita listings.
Fed straight from the local MLS and filtered to homes that note an accessory dwelling unit, whether that is a basement apartment, a detached casita, or an attached mother-in-law suite. New Syracuse listings appear here as they list, and sold homes drop off. The read on what makes one legal is just below.
No ADU or casita listings to show right now. Syracuse's full basements are standard under its newer two-story and rambler stock, but a lower level finished as a true separate apartment, with its own entrance and kitchen, is a narrower slice, a detached casita rarer still on these master-planned streets, and whether it is actually permitted is a separate question from whether it exists.

Sort permitted from existing before you tour.
A second kitchen and a side door do not make an accessory dwelling legal on their own; what matters is whether the space is permitted with Syracuse City and has proper egress on every below-grade bedroom. Tell me what setup you are after, and I will have the Syracuse-area partner agent I work with help confirm the permit history on any home you flag.

The local read
What an accessory dwelling really means in Syracuse.
An accessory dwelling is a property feature, not a promise. On a Syracuse listing it means a secondary living space that can function on its own: a second kitchen, its own bathroom, a separate exterior entrance, and sometimes a separate utility meter. The words move around. A basement apartment is a lower level built out that way, a casita is usually a detached unit set apart from the house, and a mother-in-law suite is usually an attached apartment on the main or upper floor. The search shows up across the Wasatch Front for two honest reasons, flexible living under one roof and a rentable suite where the unit is legal, and both turn on the same homework, which is whether the space is actually permitted.
Syracuse is good ground for this search for a structural reason that runs the opposite direction from the older corridor cities. The valley frost line is deep, so foundations go down and a full basement is the Wasatch Front norm, but here it sits under newer, larger homes rather than mid-century ones, because the city was mostly built after 1995 and the dominant product is a 2000s-to-2020s suburban house of three to six bedrooms. That matters for this search, because a real second kitchen and a private entrance need the ceiling height and square footage a larger newer home over a tall full basement provides, and the bigger plans are exactly what Syracuse builds, so a basement apartment is by far the most common form here. An attached mother-in-law suite on the main or upper level turns up in the larger two-story plans too. A fully detached casita is the rarest shape of all: Syracuse sits flat on the lake plain with no real slope to build a separate structure into, and on the newest west-side master-planned streets each community's own design standards generally point away from a separate detached structure, so treat a true casita as a find rather than an expectation.
Here is the part that matters more than the photos. A finished basement is not the same as a legal apartment, and neither is a converted room over the garage. A second kitchen and an outside door do not make a unit conforming on their own, and a great many existing accessory units in Utah housing were finished over the years without permits or were built before today's rules. That is not a reason to walk away, but it is the reason to verify rather than assume. Two questions decide everything: whether the unit is permitted with Syracuse City and whether it has its own legal egress, meaning a code-sized window well or door out of every sleeping room below grade. What an accessory dwelling is allowed to be on a given property depends on that parcel's zoning, so the answer is property-specific, not citywide.
Treat any income angle with the same caution. I will not quote you a rent number or a payment number on a page like this, because what a unit could earn depends on its legal status, the specific space, and rules that change, and a non-conforming unit cannot be counted on at all. What I can do is point you at the right stock. Because the separate-suite layouts ride the bigger floor plans here, the deepest, tallest basements show up on the two-story page and across the larger ramblers on the single-story page, and because a private second entrance is easier on a bigger lot with no shared-amenity rules over it, the no-HOA page pairs naturally with this search. If you only want the extra square footage and not a second kitchen, the homes with a basement page is the wider search. Earlier in the process than show me listings? Start with the Syracuse guide, and when a home below reads right, that is the moment to reach out.
What counts as an accessory dwelling
-
The form it takes: in Syracuse most of these are basement apartments, since full basements are the norm under this newer stock. Attached mother-in-law suites turn up in the bigger two-story plans too, and a detached casita is the rarest form given the flat lake-plain ground and the newest master-planned streets, so read the listing for where the space actually sits.
-
Second kitchen: a full or kitchenette setup is the core marker. A finished basement or a spare suite with no kitchen is just extra space, not a separate unit, so read the listing for the actual layout.
-
Separate entrance: the second front door this search is really about. A private exterior entry, often a walk-down or a side door, is what makes the space usable on its own rather than a through-the-house extension.
-
Separate egress: every sleeping room below grade needs a code-sized window well or a door to the outside. This is a safety item and a legality item at once, and it is the first thing to confirm in person.
-
Separate utilities: some units have their own gas or electric meter, or at least split HVAC. It is a convenience, not proof of legality, so note it but do not read it as a permit.
The local map
Where the accessory units actually are.
Homes with a second living space turn up across Syracuse, but the forms concentrate in a few patterns, and the basement apartment is by far the dominant one. Here is where to look, and the due-diligence note attached to each.
The bigger west-side plans
West of the West Davis Highway, where the newest larger contemporary homes are recording, the floor plans run big and the basements run tall and full, which is exactly the ceiling height and square footage a comfortable second kitchen and a real downstairs bedroom need. It is the strongest ground for a basement apartment and for an attached suite in the bigger plans. A detached casita is a different story: the newest Still Water streets are compact, master-planned lots, and each community's own design standards generally point away from a separate structure, so treat one as rare here. A newer build is also more likely to have been finished with permits, but you still verify it.
The Bluff Road corridor and the south end
Heavy 2010s and 2020s construction rides the old Bonneville bench along Bluff Road past Jensen Nature Park, and the larger plans here sit over full basements like the rest of the newer stock. A bigger lot on this side can make a private second entrance, and occasionally room for a detached structure, easier to fit than on a tighter west-side plat. Confirm the egress windows on the bedrooms below before you read it as a legal unit.
Central Syracuse and the 2000 West corridor
The 2000s subdivisions through the civic spine around Antelope Drive and 2000 West carry full basements throughout, some finished as separate living space or an attached suite. Stock here is a step older than the west side, so the basements can be a touch shorter, which is exactly why you stand in the actual space and read the ceiling height rather than the listing photo.
Larger two-story floor plans
The bigger two-story plans, common across every Syracuse quadrant, tend to have the deepest and tallest basements, which makes a genuine second kitchen and a real bedroom downstairs, or an attached mother-in-law suite on the upper level, more workable than in a low older basement. This is the layout where a separate-suite conversion lives most often, so read the lower-level plan on the listing closely.
East Syracuse toward the Layton line
The oldest non-farm stock, the 1990s and early-2000s homes near the I-15 interchange and Layton's retail rows, sits over full basements too, and an older basement here is more likely to predate current rules. This is the part of town where a finished lower level is most likely to be non-conforming, so it is the area where verifying the permit history matters most.
Across the city, lot by lot
Because basements are the norm under nearly all of this newer stock, an accessory unit can turn up on almost any street rather than in one enclave, and Syracuse has no community pages, so the pattern is the property, not a named subdivision. That is why the live listings above are the honest count: read each layout on its own and verify the legal status of the unit.
Before you tour: what to actually check
Is it permitted: ask the listing agent for the permit history and confirm the unit's status with Syracuse City. A second kitchen and a side door do not make a unit legal on their own.
Egress on every bedroom: each sleeping room below grade needs a code-sized egress window and well, or a door to the outside. Look at the actual window wells, not just the listing photos.
Conforming vs. existing: some accessory units are non-conforming, finished before today's rules or without permits. Understand exactly what you are buying and what can and cannot be relied on.
What the parcel's zoning allows: what an accessory dwelling can be is property-specific, not citywide, so confirm the zoning on the exact parcel with Syracuse City rather than assuming the rule from the home next door.
Attached, detached, or below grade: note which form you are actually looking at, because they live very differently. A basement apartment, an attached suite, and a detached casita each carry a different verification checklist, and on this flat lake-plain ground a walkout is not a realistic expectation for any of them.
Separate systems: check whether the kitchen, HVAC, and any meter are genuinely separate, and whether the wiring and gas work for the second kitchen were done to code and inspected.
Want a real accessory dwelling without the guesswork?
Tell me your budget, the part of Syracuse you like, whether you want a basement apartment, an attached suite, or a detached casita, and whether you need a fully permitted, conforming unit or are open to an existing space you would verify and possibly bring up to code.

Quick answers
ADU and casita shopping, answered.
It is a secondary living space that can function on its own, and the listings use several words for it. In Syracuse the most common form by far is a basement apartment, a lower level built out with a second kitchen, its own bathroom, and a separate exterior entrance. A casita usually means a detached unit set apart from the main house, and a mother-in-law suite usually means an attached accessory apartment on the main or upper level. All of them are property features describing the space, nothing more. The big thing to know is that a second kitchen and an outside door do not make a unit legal on their own, so the real work is confirming whether it is permitted and conforming with Syracuse City and what the specific parcel's zoning allows.
Some are and some are not, which is exactly why you verify rather than assume. An accessory dwelling has to be permitted with Syracuse City to be treated as a separate dwelling, what is allowed depends on the parcel's zoning, and many existing basement apartments and converted suites were finished over the years without permits or were built before today's rules, so they are non-conforming. That is not a dealbreaker by itself, but you need to know which one you are buying. Confirm the zoning, the permit history, the unit's status, and the egress independently before you rely on it, and I will help line up those checks.
Most often in the bigger newer plans, because the separate-suite layout needs the ceiling height and square footage a larger home over a tall full basement provides, and that is exactly what Syracuse builds throughout the city. The newer west-side and Bluff Road stock and the larger two-story floor plans carry the deepest, tallest basements, while the older east-side homes toward the Layton line are more likely to carry an older, possibly non-conforming lower level. On the newest west-side master-planned streets, though, the compact lot layouts and each community's own design standards generally point away from a separate detached structure, so a true casita is the rarer form here. Syracuse has no subdivision pages, so the pattern is the property, not a neighborhood. The live listings above are the honest count on any given week.
Only where the unit is legal, and that is the whole point of the verification. A permitted, conforming accessory dwelling is a different thing from a non-conforming space that happens to have a kitchen, the rules around accessory dwellings and rentals can change, and what is allowed depends on the parcel's zoning, so this is a question to confirm with Syracuse City for the specific property, not to assume from the listing. I will not put a rent figure on a page like this, because it depends entirely on the unit's legal status and the specifics, but I can connect you with a local agent who will get you straight answers on what the city allows.
Egress is a legal, code-sized way out of every below-grade sleeping room, usually an egress window with a window well sized for a person to climb out, or a door to the outside. It is both a safety requirement and a piece of what makes a basement bedroom or apartment count as legal living space. It matters most on the basement units that make up most of this search, and it is the first thing to confirm in person, because a room marketed as a bedroom downstairs is not really one without it. We check the actual window wells, not just the photos.
Tell me the budget, the part of town, and whether you need a fully permitted suite or are open to an existing space to verify, and I will connect you with a Syracuse-area partner agent and flag matching listings as they go live. Pair that with a pre-approval so you can move when the right separate-suite home lists, since these are a narrow slice and they do not sit long.
