Buying here
Sort permitted from existing before you tour.
The word that matters most in Logan is permitted: a basement apartment or attached suite only counts as a legal accessory unit if it is recognized under the parcel's zoning and Logan's rental rules, not just built with a kitchen and a door. Tell me what setup you need and I will have the Logan-area partner agent I work with pull the zoning and permit history on any home you flag.

The local read
What an accessory dwelling really means in Logan.
An accessory dwelling is a property feature, not a promise. On a Logan 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 and is by far the common form here, 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. People search for it for two honest reasons, room for multigenerational living under one roof and a separate accessory unit where the space is legal, and in this city both turn on the same homework, which is whether the unit is actually permitted and conforming under Logan's zoning and rental rules. That homework is more involved here than almost anywhere else in the state, so it is worth doing carefully.
Logan is good ground for this search for a simple structural reason, and the form it takes here is mostly the basement apartment. The valley floor sits at about 4,535 feet and the winters are cold, so foundations go down and a full basement is the norm rather than the exception, with a slab home the rarity. That means the larger homes built over full basements, the postwar-through-1990s stock across the six neighborhood councils and the bigger two-story plans, frequently carry a lower level deep enough to finish as real living space with its own grade-level door. Adding a second kitchen and a private entrance to that kind of full basement is exactly the conversion most of these listings describe. A fully detached casita is the rarest shape in a college town this established, since it takes a lot with room for a second structure, so treat one as a find rather than an expectation.
Here is the part that matters more than the photos, and it is specific to Logan. 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. In this city legality depends on the parcel's zone. Logan has owner-occupancy and rental-licensing rules that vary by zone, and some single-family zones limit whether a lower-level unit can be rented at all, the product of long-running ordinance debates over how a property may be occupied. A second kitchen and an outside door do not make a unit conforming on their own, and a great many existing accessory units in Logan's older 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. Two questions decide everything: whether the unit is permitted with Logan City under the parcel's zone and whether it has its own legal egress, meaning a code-sized window well or door out of every sleeping room below grade.
Treat any income angle with the same caution, and confirm the legal picture before you count on the income. I am not going to put a rent figure or a payment figure on a page like this, because what an accessory unit could earn depends entirely on its legal status, the specific space, and rules that change by zone, and a non-conforming unit cannot be counted on at all. What I can do is point you at the right stock. If a true separate suite is the goal, the larger homes over full basements are the natural hunting ground, so the single-story page and the two-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 because a separate entrance is easier on a bigger lot with no shared-amenity rules over it, the no-HOA page pairs naturally with this one. Earlier in the process than show me listings? Start with the Logan 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 Logan most of these are basement apartments, since a full basement is the norm in this cold valley. Attached mother-in-law suites turn up too, and a detached casita is rare in an established college town, 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 at grade, is what makes the space usable on its own rather than a through-the-house extension. Split-entry and tri-level plans lend themselves to it.
-
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.
-
Zone and licensing status: the detail Logan makes load-bearing. Whether a lower-level unit can be legally rented depends on the parcel's zone and the city's owner-occupancy and licensing rules. This is the make-or-break item, so verify it for the specific address before anything else.
The local map
Where the accessory units actually are.
Homes with a second living space turn up across Logan, 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 zoning-and-licensing note attached to each. Areas are named in plain text; verify the specific parcel's zone for every one.
The older grid: Island, Ellis, Adams, and the Center Street core
The intact early-1900s and historic blocks near downtown, the Island district by the river, and the character streets around the USU hill hold deep, full basements under older homes, which is where a lot of older lower-level conversions live. It is also the area most likely to hold a unit finished long ago without a permit, so it is where the zoning and licensing check matters most. Confirm the parcel's zone and the egress windows before anything else.
Split-level and tri-level stock across the councils
The 1960s-80s split-entries and tri-levels scattered through the council neighborhoods put a private lower-level door just a half-flight down at grade, which is exactly why so many separate-entrance conversions started in this stock. The layout suits a real second unit, whether a basement apartment or an attached suite. Confirm the egress on the lower bedrooms and the parcel's current zoning and licensing status.
Hillcrest and the older east-bench blocks
The east bench above downtown toward Logan Canyon carries larger lots and full basements, some finished as separate living space, and the bench grade can give a lower level real daylight windows. A newer or updated finish is more likely to have been permitted, but you still verify the zone, the licensing, and the egress for the specific home.
Larger postwar homes over full basements
Across the six council neighborhoods, the bigger postwar-through-1990s single-family homes are the natural home for a comfortable downstairs unit or an attached suite, since their basements run deep enough for a real second kitchen and a legal bedroom. A larger footprint upstairs usually means a more workable separate space below. Read the lower-level layout and confirm the zone.
Walkout and daylight lots toward the benches
On the sloped bench and canyon-mouth lots, a lower level can open to grade with full windows and its own door, which is the ideal setup for a separate suite that lives like its own floor rather than a dark below-grade basement. These are less common in Logan than flat valley-floor lots, and a bigger bench lot is also about the only place a detached casita has room to sit, so watch for both and still run the full legality check.
Newer west and southwest Bridger plats
The newer single-family stock pushing west and southwest toward the valley floor was more likely built with permitted, conforming finishes, and a younger full basement can be finished as separate space cleanly. A newer build does not skip the homework, though: confirm the parcel's zone, the licensing rules, and whether the lower level was permitted as a unit.
Before you tour: what to actually check
The zone and the licensing rules: this is Logan's make-or-break item. Whether a lower-level unit can be legally rented depends on the parcel's zone and the city's owner-occupancy and rental-licensing rules, which vary by zone. Confirm the specific address with Logan City before you fall for the finishes.
Is it permitted: ask the listing agent for the permit history and confirm the accessory unit's status with Logan City. A second kitchen and a side door do not make a lower level a legal dwelling on their own, and many older Logan units were finished without permits.
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, since this is both a safety item and a piece of what makes the space legal.
Conforming vs. existing: many older Logan accessory units are non-conforming, finished before today's rules or without permits. Understand exactly what you are buying, what can be relied on, and what cannot, rather than assuming the listing's separate-unit language settles it.
Separate systems and code work: check whether the kitchen, HVAC, and any meter are genuinely separate, and whether the wiring, plumbing, and gas for the second kitchen were done to code and inspected. A separate meter is a convenience, not proof of legality.
The age package and the utilities: Logan bills electric, water, sewer, stormwater, and garbage on one city utility account with gas billed separately, so check the setup, and on any older-grid home date the roof, furnace, electrical panel, and sewer lateral while you are at it.

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 Logan 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 in Logan 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 Logan City and whether the specific parcel's zone allows a lower-level unit to be rented at all.
Some are and some are not, which is exactly why you verify rather than assume, and Logan makes this homework heavier than most Utah cities. An accessory dwelling has to be permitted with Logan City to be treated as a separate dwelling, whether a lower-level unit can be legally rented depends on the parcel's zone, and Logan has owner-occupancy and rental-licensing rules that vary by zone. 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 zone, the licensing requirements, the permit history, and the egress independently before you rely on it, and I will help line up those checks.
Most often in the older grid near downtown, the Island district, and the character blocks around the USU hill, which sit over the deepest full basements and carry most of the older lower-level conversions. The 1960s-80s split-entries and tri-levels across the council neighborhoods suit a separate entrance, the larger postwar homes over full basements give a downstairs unit room to work, and on the sloped east-bench and canyon-mouth lots a daylight or walkout lower level can make the space live like its own floor. A fully detached casita is the rarest form here, because it takes a lot with room for a second structure. The live listings above are the honest count on any given week.
Only where the unit is legal under the parcel's zone, and that is the whole point of the verification. Logan has owner-occupancy and rental-licensing rules that vary by zone, and some single-family zones limit lower-level rentals, so a permitted conforming accessory dwelling is a very different thing from a non-conforming space that happens to have a kitchen. The rules have been debated and revised over the years and can change, so this is a question to confirm with Logan City for the specific property and zone, 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 Cache Valley agent who will get you straight answers on what the city allows for that parcel.
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 Cache Valley 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 in Logan and the legal-versus-existing question narrows it further.
