ADU Design
Site evaluation, concept floor plans and construction-ready drawings shaped around your lot.
ADU design and construction for West Bountiful homeowners. Flat ground, generous yards and short utility runs make this one of the easier places in Davis County to add a detached unit.
No obligation. Every estimate starts with a straightforward conversation and a walkthrough of your lot.

West Bountiful is a small city of roughly 5,900 people covering 3.2 square miles in south-eastern Davis County, bounded by Centerville to the north, Bountiful to the east, Woods Cross to the south and the Legacy Nature Preserve to the west. It sits about eleven miles north of downtown Salt Lake City.
For ADU purposes, the important thing is that West Bountiful sits firmly on the valley floor, west of the bench. There is no meaningful slope to design around. Foundations are simpler, drainage planning is simpler, and equipment can usually reach a rear building site without difficulty — three things that quietly remove cost and risk from a detached build.
The housing stock is established, overwhelmingly owner-occupied and family-oriented, with nearly three-quarters of households being married couples. Vacancy sits near 2%. These are settled properties where people are planning around family rather than turnover — which is exactly the profile of homeowner who builds an ADU for a parent or an adult child.
Yards here tend to be more generous than in the tighter cities immediately south, which widens the options. Where a Woods Cross homeowner might be weighing a basement conversion, a West Bountiful homeowner more often has room to consider a purpose-built backyard unit.
Off the bench and on the valley floor, West Bountiful lots avoid the stepped foundations, retaining and drainage engineering that sloped east-side properties require.
Yards here are often generous enough for a standalone backyard unit without giving up the whole garden — which is the main reason detached builds come up more here than in the tighter cities to the south.
Around three-quarters of households are married couples and vacancy is around 2%. These are long-term family properties, which is the typical profile for a unit built for a parent or adult child.

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.
The things worth establishing on a West Bountiful property:
Because so many West Bountiful properties can genuinely support either route, the walkthrough usually ends with a comparison rather than a single recommendation: a detached ADU for maximum separation, or a garage conversion or basement conversion for lower cost and a shorter build.
Utah state law makes internal ADUs a permitted use in most residential zones statewide. Detached units fall under West Bountiful City ordinance, and cities may apply parking, owner-occupancy and rental licensing requirements. Requirements change over time, so confirm the current position with West Bountiful City as part of planning — we prepare the documentation and coordinate the process.
More often here than in most of the neighbouring cities, because yards tend to be larger and the ground is flat. The limiting factor is usually setbacks rather than total area. During siting we mark out the footprint against your real yard so the trade-off between building and garden is a decision you make with your eyes open.
Yes, though not dramatically. You avoid retaining work, deep excavation and complex drainage, and equipment reaches the site easily. The larger cost drivers remain finish level and how far the unit sits from existing utility service.
If the garage is structurally sound with workable ceiling height, converting is normally faster and less expensive than building new — and it leaves the yard intact. The trade is parking and storage, which you cannot easily undo. We look at both and tell you which one your property actually favours.
Very close — we are based in Bountiful, immediately east. Site visits are quick to arrange and there is no travel premium in the estimate, which also means the crew is not losing time in transit during a months-long build.
