ADU Design
Site evaluation, concept floor plans and construction-ready drawings shaped around your lot.
ADU design and construction for Kaysville homeowners. Larger lots and settled, owner-occupied housing make this one of the better places in Davis County for a purpose-built detached unit.
No obligation. Every estimate starts with a straightforward conversation and a walkthrough of your lot.

Kaysville sits at about 4,298 feet in Davis County, covering 10.5 square miles with roughly 32,900 residents. It is bordered by Layton to the north, Fruit Heights to the east and Farmington to the south. Around 77% of households are married couples, more than half have children under 18, and the homeowner vacancy rate is 0.4% — an unusually settled housing market even by Davis County standards.
That stability is why ADU conversations here so often start with family. People are not planning to move. They are planning for a parent who should not be climbing stairs, or an adult child who needs somewhere to live while they save, or a guest suite that they expect to become a rental in a decade.
Lot sizes work in your favour. Kaysville properties tend to be more generous than the Davis County average, which widens the options considerably — a detached backyard unit can often be built without consuming the entire garden, which is the trade that kills the idea on tighter lots further south.
Ground here sits between the Wasatch foothills to the east and flatter land to the west, so grade varies. It is rarely severe, but it is worth establishing before assuming a simple slab.
Kaysville properties tend toward the larger end for Davis County, which makes a detached backyard unit realistic without giving up the entire garden.
Homeowner vacancy around 0.4% and roughly 77% married-couple households. People here are building for the long term, which is the classic case for a permanent second dwelling.
Between the foothills and the flats, most Kaysville lots carry manageable grade rather than the meaningful slope you find further south on the bench — but it still gets measured rather than assumed.

Full-scope building from foundation and framing through mechanical rough-in and final finishes.

Turning an attached or detached garage into a self-contained unit using what is already on site.

Standalone backyard units with their own foundation, entrance and utility connections.

Additions sharing a wall or roofline with the main house while staying fully self-contained.

Updating an existing ADU, basement apartment or converted space to a livable standard.
On a Kaysville property these are what shape the design:
Kaysville is one of the places where a detached ADU genuinely tends to be the right answer rather than the aspirational one. Where the budget or the timeline points elsewhere, a garage conversion or basement conversion still delivers a self-contained unit for less.
Utah state law makes internal ADUs a permitted use in most residential zones statewide. Detached units are governed by Kaysville City ordinance, and cities may apply parking, owner-occupancy and rental licensing requirements. Rules change, so confirm the current position with Kaysville City during planning. We prepare what the process requires and coordinate it with you.
More often than not in Kaysville. But total area is rarely the binding constraint — setbacks are. During siting we lay the footprint out against your actual yard, with setbacks marked, so you can see exactly what would remain before anything is committed.
Yes, and on a lot with room it is one of the strongest arguments for building detached rather than converting a basement. A ground-level unit with a level entrance removes the stairs problem entirely, and that is usually the whole point of the exercise.
It depends on distance, what has to be crossed and where the existing connections sit — which is why we will not put a figure on it before seeing the property. On deep Kaysville lots it is one of the larger single line items in a detached build, so it gets established early rather than discovered late.
A straightforward drive north from Bountiful. Site visits are easy to arrange and there is no travel premium built into the estimate.

Kaysville is one of the easier places in Davis County to build a genuinely separate unit, because the lots are generous enough that you are not choosing between an ADU and a garden.
We design and build detached ADUs, attached ADUs, garage conversions and basement conversions for homeowners throughout Kaysville and Davis County.
