Boise pre-approved ADU plans

Pick a plan. We'll build it.

The City of Boise has pre-approved a catalog of ADU plan sets, ready for permitting. Browse them below, then call us — we handle site work, permitting, and construction.

The pre-approved plan sets

Each of these plan sets has already been through Boise's Planning & Development Services review, which means faster permitting and lower design costs. Choose one based on your lot, your budget, and how you plan to use the space.

Each card links to the City of Boise's pre-approved ADU plans page, where you can download the full plan-set PDFs free of charge.

Not limited to the catalog

A wider library of designs

The city's plan sets are just the starting point. We build from a broad library of ADU designs, so if none of the pre-approved sets fits your lot or your style, there are plenty more to choose from.

Custom plans by our design department

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