Building in Idaho since 1991 · Contractor license RCE-473

Your backyard is sitting on untapped value.

A well-built ADU turns your property into rental income — or gives your family room to grow. And with Idaho's new ADU law in effect since July 1, 2026, there has never been an easier time to build.

Boise's pre-approved ADU plan sets

Two ways an ADU pays you back

Why homeowners are adding ADUs

Cozy backyard guest cottage with warm evening light

Generate rental income

A long-term renter or a short-term stay can turn your backyard into a monthly paycheck. Many ADUs help cover the mortgage while your property value climbs — income now, equity later.

Small detached guest house with porch and garden

Room for extended family

Keep parents, adult kids, or guests close — with real privacy. A separate entrance, kitchen, and bath make multigenerational living comfortable for everyone under your roofline.

8

pre-approved plan sets from the city of Boise

Start from a plan the city has already approved

Boise has done the hard part: a catalog of eight ADU plan sets is pre-approved, and as of July 1, 2026 a new Idaho law clears the way for ADUs on more properties statewide. Pick a plan, and we handle the rest — permitting, site work, and construction.

More than the catalog

The pre-approved Boise plan sets are just the starting point — we build from a wide library of other ADU designs, so there's a layout for nearly every lot and budget.

Fully custom, in-house

Have something specific in mind? Our design department can draw a custom ADU plan tailored to your property, your needs, and your style — then build it.
