Sort legal from existing before you tour.
A second kitchen and a private entrance do not make a unit legal on their own here, since what is allowed runs through the parcel's zoning and the city's permit history. Tell me what setup you need, a basement apartment, an attached suite, or a detached casita, and I will have the Mapleton-area partner agent I work with pull the permit history on any home you flag.

The local read
What an accessory dwelling really means in Mapleton.
An accessory dwelling is a property feature, not a promise. On a Mapleton 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 two honest reasons the search exists are flexible living under one roof and, where the unit is legal, a rentable suite, and both turn on the same homework, which is whether the space is actually permitted with the city.
Mapleton is workable ground for this search, and the form it takes here is mostly the basement apartment. Basements are the Wasatch Front and bench standard, and on Mapleton's sloped east side a daylight or walkout basement is natural, where the lower level can open to grade with full windows and a real door. That kind of full, daylight basement is exactly the kind that gets a second kitchen and a private entrance added. The larger homes the city's big-lot, agricultural-residential market tends to produce, the bench customs and the larger newer builds, are where a roomy lower-level living space most often appears, since there is square footage to give it. Those same large lots and acreage parcels are also the rare place a detached casita has genuine room to sit apart from the main house, so treat one as a find rather than an expectation. One honesty note specific to Mapleton: the city hub does not call out accessory units as a named market, so treat this as a property and layout feature, not as evidence of a busy rental scene the local data does not describe.
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 or a guest building 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, so they are non-conforming. That is not a reason to walk away, but it is the reason to verify rather than assume. What is allowed depends on the parcel's zoning, and Mapleton runs several zones, so the rules are not uniform across the city. The two questions that decide everything are whether the unit is permitted with Mapleton City and whether it has its own legal egress, meaning a code-sized window well or door out of every below-grade 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 larger floor plans are the natural hunting ground for a real separate suite, so the two-story page and, where a roomy rambler sits over a full daylight basement, the single-story page are useful next stops. If you only want the extra square footage and not a second kitchen, the homes with a basement page is the wider search, and the larger lots on the no-HOA page can give a separate entrance and parking more room to work. Earlier in the process than show me listings? Start with the Mapleton 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 Mapleton most of these are basement apartments, since basements are the norm in this bench stock. A detached casita has real room on the larger lots and acreage here, and an attached mother-in-law suite turns up too, 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, on Mapleton's sloped bench lots, a walkout door at grade, is what makes the space usable as 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 Mapleton, 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 east side and the sloped bench
On the rising bench toward Maple Canyon, the grade makes a daylight or walkout basement natural, where the lower level opens to full windows and a door at grade. That is the ideal setup for a separate suite that lives like its own floor rather than a dark basement, which is why the bench is the most promising ground for a real second living space. The slope is the asset and the homework at once, so read drainage and how the lower level meets grade.
Larger bench and acreage custom homes
Because the agricultural-residential zoning and large lots push toward custom and small-plat building, the bench and acreage customs often have the square footage for a roomy lower-level living space, a comfortable second kitchen, and a real bedroom downstairs. A larger lot also gives a separate entrance and its own parking more room to work, and, uniquely here, real room for a detached casita set apart from the main house. Verify the permit status, since a bigger, custom basement or a separate structure is still only a legal unit if the city says so.
Larger newer homes citywide
The newer estate-style and larger production homes, including the new-construction segment reported near an $800,000 median, tend to have the deepest and tallest basements, which makes a separate lower unit more workable than in a short older basement. A newer build is more likely to have been finished with permits, but you still confirm it for the specific home rather than assuming the age guarantees the paperwork.
Established homes near the old core
The longest-established blocks around Maple Street and the historic center hold older homes on city water and sewer, some with basements finished over the decades. These are the most likely to carry a lower-level space that was built before today's rules or without a permit, so this is exactly the area where verification matters most. Confirm the egress windows on any below-grade bedrooms before you count the space.
The growing west side and valley floor
The newer subdivisions toward Springville and the valley floor carry full basements too, some finished as separate living space, with younger systems behind them. The lots are flatter here, so a walkout is less of a given and a separate entrance is more often a walk-down, but the floor plans can still support a real lower unit. As always, the question is whether it is permitted, not just whether it is finished.
Acreage parcels with room to spread out
On the larger agricultural-residential lots, a basement apartment, an attached suite, or even a fully detached casita pairs with genuine room around the house for separate parking and a private entrance away from the main door. The trade is the rest of the acreage homework, since a fringe parcel may be on a private well and septic, which can bear on what an additional living unit means. Confirm the zoning, the permit status, and the utilities together on these.
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 Mapleton City, since what is allowed depends on the parcel's zoning. 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, and note that a walkout door on the bench can satisfy this where it exists.
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, and confirm it for the specific parcel's zoning.
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.
Attached, detached, or below grade: note which form you are actually looking at, because they live very differently, and an older basement can be low. Stand in it. Tall, daylight, or walkout lower levels, common on Mapleton's bench, live very differently from a short, fully below-grade basement.
Water, utilities, and the rest: confirm whether the parcel is on Mapleton City water and sewer or a private well and septic on the fringes, since that bears on an additional living unit, check whether Mapleton Fiber serves the address, and on any older-core 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 listings use several words for it. In Mapleton 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, which the larger lots and acreage here give real room for, 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 Mapleton 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 Mapleton 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 on the sloped east-side bench toward Maple Canyon, where a daylight or walkout lower level opens to grade and makes a real separate entrance natural, and in the larger bench, acreage, and newer custom homes that have the square footage for a roomy suite. The big agricultural-residential lots are also where a detached casita has genuine room to sit, which is rarer in a tighter city. Established homes near the old core around Maple Street can carry older finished basements too, which is where verification matters most. 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 Mapleton 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, which a walkout lower level on the bench can provide. 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 Mapleton-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.
