Accessory dwelling unit
(ADU)

A second living unit on your property — for family, guests, rental income, or all three.

What an ADU actually is

An Accessory Dwelling Unit is a second, self-contained living unit on a single-family lot. It has its own kitchen, bathroom, and entrance. It can sit attached to the main house, above a garage, in a finished basement, or as a stand-alone cottage in the backyard.

People use them for aging parents who want their own space, adult kids saving for a down payment, long-term guests, a serious home office, or rental income — and a lot of homeowners end up using them for all of the above over the years. The main thing that determines what's possible on your lot is local zoning, which varies by city across Utah. We've built ADUs in Heber, Wasatch County, and across the valley, and we know what most local codes will and won't let you do.

Why people are building them

Rental income
A long-term tenant or short-term rental can cover a chunk of the mortgage. In some of Utah's tighter rental markets, an ADU pays for itself faster than you'd expect.
Multigenerational living
A separate space for aging parents, adult kids saving up, or a sibling between moves. Close enough to be together, far enough that everyone gets their own door.
Smaller footprint
An ADU is one of the most efficient ways to add housing in an existing neighborhood — no new sprawl, lower utility costs per occupant, and modern envelopes that hold heat in a Utah winter.
Property value
Done well, an ADU adds real value to your home — appraisers treat it as additional dwelling area, and buyers actively look for properties with one.
Flexibility over time
What works for your family this year is rarely what works in five. A good ADU shifts between guest house, home office, studio, and rental as life changes — we design with that in mind.

Why work with us on your ADU

We know the zoning
Every Utah city handles ADUs a little differently — setbacks, max size, parking, utility hookups. We've been through it enough times to tell you up front what your lot will allow.
We design around how you'll actually use it
A long-term rental and a guest cottage for your in-laws are not the same building. Tell us how you'll use it, and we'll lay it out so it works for that — not just whatever looks good on a plan.
Smart use of small space
We do this on commercial flex space all the time — get more out of fewer square feet. Vaulted ceilings, full-height windows, real storage, and layouts that don't feel like an afterthought.
Built to last
The same trades and materials we use on a custom home — proper framing, real insulation, solid finish work. It should hold up for decades, not just look good in photos the day we hand you the keys.
One team, start to finish
Design, permitting, construction, inspections, walk-through — same project manager from day one. You don't get handed off, and you don't have to keep re-explaining your project.
