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 South Weber 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. A separate living space in South Weber usually means a basement apartment carved into an older valley-core rambler or a newer bench two-story, and the bench slope can give a walkout basement a genuine second entrance rather than a dark stairwell; a fully detached casita is rarer and turns up mainly on the larger bench and canyon-mouth lots.

A second kitchen and a side door do not make an ADU or casita legal on their own, so the real question is whether the unit is permitted with South Weber City and whether every below-grade bedroom has proper egress. Tell me what setup you need and I will have the South Weber-area partner agent I work with pull the permit history before you tour.

The local read
What an ADU or casita really means in South Weber.
An accessory dwelling is a property feature, not a promise. On a South Weber 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 level. The search shows up for two honest reasons, a separate living space 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 with South Weber City.
South Weber is reasonable ground for this search for a structural reason that has to do with the land. This is a foothill-bench town in Davis County, set on the south bank of the Weber River at the mouth of Weber Canyon, and the ground climbs as you move toward the canyon and the southern bluff. A full basement is the regional norm here, so the older mid-century ramblers in the original valley core near South Weber Drive sit over basements that have been finished and refinished over the decades, and that is exactly the kind of full basement most of these conversions describe. The newer two-story homes climbing the bench carry full basements too, and a newer plan is more likely to have a tall lower level that lives well as a separate space. A fully detached casita is the rarest shape here, since it takes a lot with real room for a second structure, so treat one as a find on the larger bench or canyon-mouth parcels rather than an expectation anywhere in town.
The bench grade adds a second, better path to a separate entrance. Where the lots step uphill toward Weber Canyon and the bluff, a lower level can open to grade as a daylight or walkout basement, with full-size windows and a real door instead of a dark stairwell. That makes a natural second front door, which is the whole point of a separate suite, and it is one reason the bench is worth watching for this search even though the older valley core holds more of the existing units. On the low ground toward the Weber River, by contrast, the flat grade does not support a walkout, so a built-out lower level there is a below-grade conversion and the FEMA flood map on that parcel is the homework, not the entrance.
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 off the main floor or a small guest structure out back. A second kitchen and an outside door do not make a unit conforming on their own, and a great many existing accessory units in older 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. 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 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: the older valley-core homes and the larger newer bench plans are the natural hunting ground, so the single-story page and the two-story page are useful next stops, and the no-HOA page covers the freer-to-modify older and larger-lot parcels. 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 South Weber guide, and when a home below reads right, that is the moment to reach out.
What counts as an ADU or casita
-
The form it takes: in South Weber most of these are basement apartments. A detached casita or an attached mother-in-law suite turns up too, mostly on bigger bench and canyon-mouth lots, 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 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, and on the bench a daylight or walkout grade can give you a real one at the back.
-
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, not from the photos.
-
Separate utilities: some units have their own gas or electric meter, or at least split HVAC. South Weber power comes from Rocky Mountain Power, so a separate meter is a utility-and-city question. It is a convenience, not proof of legality.
The local map
Where the ADUs and casitas actually are.
Homes with a second living space turn up across South Weber, but the forms concentrate in a few patterns, and the basement apartment is by far the most common one. Here is where to look, and the due-diligence note attached to each. These are descriptive areas, not official plats; confirm any subdivision name with South Weber City and Davis County records.
The original valley core
The older established blocks on the flatter ground near South Weber Drive, where the oldest mid-century ramblers and some older farmsteads sit on mature lots tied to city culinary water and sewer. These sit over basements that have been finished over the decades, which makes them the most likely place to find a real separate suite, and also the most likely place to find one finished without a permit. This is the area where verification matters most.
The bench and foothill subdivisions
Where the homes climb the bench toward the canyon mouth and the southern bluff, the slope lets a lower level open to grade as a daylight or walkout basement with a real back door and full windows. That natural second entrance is the ideal setup for a separate suite that lives like its own floor, and a bigger bench lot is also the likeliest place to find room for a detached casita. On the bench you are also checking slope, drainage, and the secondary irrigation water, so the lot homework rides along with the accessory-unit question.
The newer two-story bench product
The newer two-story homes on the bench often have the deepest and tallest basements, which makes a comfortable second kitchen and a real bedroom downstairs more workable than in a low older basement. A newer build is more likely to have been finished with permits, but you still confirm the unit's status and the egress windows on every bedroom below grade. Read the finished-basement square footage and the ceiling height into what you are buying.
The canyon-mouth east edge
Closest to where Weber Canyon opens, with outdoor access and some larger parcels, a daylight or walkout basement on the slope makes a natural separate suite, and the larger lots here are also where a detached casita has the room to sit. This is also the windiest exposure in town, where the canyon wind funnels out, so feel the site on a windy day, and check the canyon-drainage FEMA flood mapping per parcel alongside the accessory-unit question.
The river-and-trail north edge
Toward the Weber River and the Parkway Trail along I-84, an older or larger-lot home can carry a built-out lower level. This is flat, low ground rather than sloped bench ground, so a built-out level here reads as a below-grade conversion, not a walkout, and the FEMA flood mapping is worth checking parcel by parcel before you weigh it against the accessory unit. This edge is also closest to the I-84 and I-15 commute tie-in.
The larger and semi-rural lots
On the bigger bench and canyon-mouth parcels, an outlying home can pair a built-out lower level, or occasionally a detached casita, with the room outside for parking and outbuildings. On these you are also verifying secondary irrigation shares and any well or septic, so the lot due diligence sits right next to the accessory-unit question, and a daylight basement on a slope is the most workable separate-suite setup out here.
Before you tour: what to actually check
Is it permitted: ask the listing agent for the permit history and confirm the unit's status and the parcel's zoning with South Weber City. A second kitchen and a side door do not make a unit legal on their own, and what is allowed depends on the parcel.
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, and note where a walkout door gives you the cleanest exit.
Conforming vs. existing: many older 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.
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. South Weber power runs through Rocky Mountain Power and gas through Dominion Energy, so a meter split is a utility-and-city question.
Attached, detached, or below grade: note which form you are actually looking at, because they live very differently. An older basement can be low and dark, so stand in it. A tall, daylight, or walkout lower level on the bench lives very differently from a short, fully below-grade basement, and the grade out back tells you which one you have.
Water and the older-home checklist: South Weber runs city culinary water plus a separate secondary irrigation system, so check both, and on any older valley-core home date the roof, furnace, electrical panel, and sewer lateral. On bench and larger lots confirm whether secondary irrigation shares serve the parcel.

Quick answers
ADU and casita shopping, answered.
It is a secondary living space that can function on its own, and the listings use a few different words for it. In South Weber the most common form 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 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 South Weber 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 South Weber 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 in older homes 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 original valley core near South Weber Drive, where the older ramblers sit over basements finished across the decades, and on the newer bench subdivision streets, where taller, newer basements sometimes include a built-out lower level. On the bench toward the canyon mouth, a sloped or walkout lot can make the lower level open to grade with a real back door, which is the ideal separate-suite setup. A fully detached casita is the rarer form and turns up mainly on the larger bench and canyon-mouth parcels that have the room for a second structure. 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 South Weber City for the specific property. 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 on the bench a walkout or daylight grade can give you a real door, which is the cleanest version of egress. It is the first thing to confirm in person, because a room marketed as a bedroom downstairs is not really one without it, so 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 South Weber-area partner agent and flag matching listings as they go live. Pair that with a pre-approval so you can move when the right home lists, since these are a narrow slice in a small market and they do not sit long.
