We only build ADUs
Boise ADU isn't a general contractor that also does kitchens. ADUs are the only thing we build — the plans, the permits, the foundation details, the rental finish-out. Specialization compounds.

What does a Boise ADU builder actually do?
An ADU builder in Boise turns your backyard into a permitted, code-compliant secondary dwelling unit — a backyard home, garage conversion, attached suite, or a pre-approved studio. The right builder owns the whole job: plan selection, site evaluation, permit drawings, City of Boise submittals, foundation, framing, MEP, finishes, inspections, and the final certificate of occupancy. You sign one contract for one fixed price.
Boise has six City-published pre-approved ADU plans (Type A through Type G-2) that skip 4-8 weeks of design review. We build every one of them, plus fully custom plans for lots or use cases that the pre-approved set doesn't fit. If you've never built before, the first 30 minutes of the free estimate covers what's physically possible on your lot, what permits will cost, and which plan delivers the best return for your situation.
Why work with us
Boise-specific permitting expertise
We pull permits in Boise, Meridian, Eagle, Nampa, Kuna, Star, Caldwell, and Garden City. Each city has its own ADU rules — we know the difference between Boise's R-1A setbacks and Garden City's mixed-use overlays.
Pre-approved plan economics
If a pre-approved plan fits your lot, you save 4-8 weeks of design review and roughly $8-15k in design fees. We default to pre-approved unless your situation genuinely needs custom.
Plain-English communication
No contractor jargon, no allowance line items you have to decode. You get the cost up front, the timeline up front, and the answer to 'what does this affect' in plain language.
The 6 pre-approved plans we build
City of Boise pre-approved means the design has already been reviewed and approved. Permitting drops to ~3-5 weeks instead of 10-12. Each plan has a published Boise.gov PDF and a real cost range we can quote on day one.
