Homes with an ADU or casita in Kaysville.

An accessory dwelling is a property feature, not a promise. On a Kaysville 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 separate suite where the unit is legal, and both turn on the same homework, which is whether the space is actually permitted.

Kaysville is good ground for this search, and the form it takes here is mostly the basement apartment. This is not a warm-desert slab market, it is a cold-climate bench town where foundations go below the frost line, so full basements are standard rather than a bonus. The central Kaysville subdivisions between Main Street and I-15, the post-war-through-2000s grid, and the older bench streets carry a deep stock of full and finished basements that already double the living space, and adding a second kitchen and a private entrance to that kind of basement is exactly the conversion most of these listings describe. The east bench adds a second pattern: on the sloped foothill lots toward the Fruit Heights line and the mouth of Adams Canyon, a lower level can open to grade as a daylight or walkout level with full windows and a real door. A fully detached casita is the rarest shape in an established, largely built-out city, 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. 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. 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 Kaysville City and whether it has its own legal egress, meaning a code-sized window well or door out of every sleeping room below grade. Kaysville also runs its own municipal power utility, so the meter and the utility setup on a separate unit can look different here than in the rest of Davis County, and that is worth confirming with the city too. 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 can change, 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 central and bench ramblers are the natural hunting ground, so the single-story page and the two-story page are useful next stops, since the bigger two-story plans carry the deepest basements. If you only want the extra square footage and not a second kitchen, the homes with a basement page is the wider search. A separate entrance is also easier on a bigger, older lot with fewer restrictions over it, so lot size and age are worth weighing as you look. Earlier in the process than show me listings? Start with the Kaysville guide, and when a home below reads right, that is the moment to reach out.
