The local read
What an ADU or casita really means in Riverton.
An accessory dwelling is a property feature, not a promise. On a Riverton listing it can mean a few different things: a basement apartment where the lower level has been built out as a self-contained living space, a detached casita set apart from the main house, or an attached mother-in-law suite on the main or upper floor. Each version usually carries a second kitchen, its own bathroom, a separate exterior entrance, and sometimes a separate utility meter. The search shows up for two honest reasons, multigenerational 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.
Where Riverton helps the search is its mix of housing. The city reads as three age-of-stock layers laid down along its three north-south roads: older, larger-lot, farm-era homes on the east side near the Jordan River and the historic civic core around 12600 South, the big 1990s and 2000s subdivision band through the center between Redwood Road and Bangerter, and 2010s and 2020s single-family and townhome product on the newer west bench out toward the Mountain View Corridor. The bigger, newer floor plans are the ones most likely to carry a built-out basement apartment with its own entrance, while the larger legacy lots on the east and southeast give a detached casita or a separate suite room to breathe.
Here is the part that matters more than the photos, and the part Riverton-specific honesty demands. Do not assume every home here has a finished basement, let alone a legal accessory dwelling. Treat the lower level, or any separate structure, as something to confirm at the parcel rather than expect. And a finished space, where one exists, is not the same as a legal unit: a second kitchen and an outside door do not make it conforming on their own, and a great many existing basement apartments 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. It is the reason to verify rather than assume. The two questions that decide everything are whether the unit is permitted with Riverton City and whether it has its own legal egress, meaning a code-sized window well or door out of every sleeping room.
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. The bigger plans on the two-story page often carry the deepest lower levels for a basement apartment, an established single-story rambler on a larger east-side lot can hold a real separate suite or a detached casita, and the freedom of a no-HOA parcel often matters when a separate entrance and extra parking are in play. If you only want the extra finished square footage and not a second kitchen, the homes with a basement page is the wider search, a different intent than this one. Earlier in the process than show me listings? Start with the Riverton 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 Riverton most of these are basement apartments, since the older east-side and central stock make that conversion the most common option. A detached casita or an attached suite is rarer, more workable on the larger legacy lots, so read the listing for where the space actually sits.
-
Second kitchen: a full or kitchenette setup is the core marker, whether it sits in a basement apartment, a casita, or an attached suite. A finished basement with no kitchen is just finished space, not a separate unit, so read the listing for the actual layout.
-
Separate entrance: the second front door of the page title. A private exterior entry, a walk-down, a side door, or a stand-alone casita 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 ADUs and casitas actually are.
An accessory dwelling can turn up anywhere in Riverton, but a true separate suite concentrates in a few patterns, and the basement apartment is the most common form. Here is where to look, and the due-diligence note attached to each.
The east side along Redwood Road
The oldest part of town, near the Jordan River bottoms and the historic civic core around 12600 South, holds mid-century through 1990s homes on the city's larger legacy lots. The lot size gives a separate entrance and extra parking room to work, whether for a basement apartment or a detached casita, and older homes are the most likely to carry a basement that was finished over the years, which is also why this is where verifying permits and egress matters most. This is also the lowest ground in the city, close to the river bottoms, so read the water table and drainage here the way you would on any bottomland parcel.
The larger southeast lots toward Bluffdale
The quieter southern streets toward the Bluffdale line keep some of Riverton's larger legacy lots. More land around the house makes a code-compliant separate entrance or a detached casita, its own parking, and any required setbacks easier to satisfy than on a tight interior lot. Confirm the parcel's zoning and the unit's status with the city.
The central subdivision band
Between Redwood Road and Bangerter sits the 1990s and 2000s subdivision fabric, the city's biggest single slice of inventory. Many of these standard two-story homes have full basements, and some have been finished as a basement apartment. A newer build is more likely to have been finished with permits, but you still verify it.
Larger two-story plans
The bigger two-story floor plans, more common in the newer central and west-bench builds, often have the deepest and tallest basements. That makes a comfortable basement apartment, with a real second kitchen and a real bedroom downstairs, more workable than in a low older basement, where ceiling height can be the limiting factor.
The newer west bench
Bangerter out to the Mountain View Corridor is the newest construction, on the former farm fringe near Mountain View Village. Lots are smaller and the product leans toward townhomes near the retail core, so a detached home with a true basement apartment or casita is less common here, but the systems are the youngest in the city when one does list.
Walkout and daylight lots
Riverton rises gently westward from the river bottoms toward the west bench, so some lots on the higher ground step enough for a lower level to open to grade with full windows and a real door. That is the ideal setup for a basement apartment or suite that lives like its own floor rather than a dark basement. These are less common on the flatter river-bottom side but worth watching for on the west bench.
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 Riverton City. A second kitchen and a side door or a stand-alone casita do not make a unit legal on their own, and what is allowed depends on the zoning.
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: many older basement apartments and converted spaces 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.
Ceiling height and light: an older basement can be low. Stand in it. A tall, daylight, or walkout lower level lives very differently from a short, fully below-grade basement.
Secondary water and the rest: Riverton runs culinary plus secondary pressurized irrigation water, so confirm the parcel's hookups and bills. On any east-side home near the river bottoms, also check the water table and drainage, and on any older home, date the roof, furnace, electrical panel, and sewer lateral.

Quick answers
ADU and casita shopping, answered.
It is a secondary living space that can function on its own, and the search covers a few forms. A basement apartment is a lower level built out with a second kitchen, its own bathroom, and a separate exterior entrance. A casita usually means a small detached structure set apart from the main house, and a mother-in-law suite usually means an attached apartment on the main or upper floor. All three are property features describing the space, nothing more. The big thing to know here is that a second kitchen and an outside door do not make any of them legal on their own, so the real work is confirming whether the unit is permitted and conforming with Riverton City.
Some are and some are not, which is exactly why you verify rather than assume. An ADU, casita, or basement apartment has to be permitted with Riverton City and match the parcel's zoning to be treated as a separate dwelling. Many existing units 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 on the older east side along Redwood Road and the larger legacy lots on the southeast toward Bluffdale, where the lot size gives a separate entrance, parking, and sometimes room for a detached casita. The central subdivision band and the bigger newer two-story plans can carry a built-out basement apartment too, and a home on a walkout lot can let the lower level live like its own floor. 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 unit is a different thing from a non-conforming space that happens to have a kitchen, and the rules around rentals can change, so this is a question to confirm with Riverton 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 for a basement apartment specifically, 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 unit or are open to an existing space to verify, and I will connect you with a Riverton-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.
