Permitting and construction
We file permits and manage every trade from foundation through finish with weekly written updates.
Inspections and closeout
Final inspections are coordinated and we walk through every detail before handoff.
Typical timeline
Most ADU projects run 4 to 7 months from design through certificate of occupancy, depending on unit size, site conditions, and permit timelines.

ADU / Guest House cost in Caldwell
Planning ranges for Caldwell match the broader Treasure Valley market. As of 2026, garage conversions in the Boise area typically plan $90,000 to $180,000. Attached ADUs and basement conversions plan $120,000 to $250,000, and detached new-build ADUs plan $180,000 to $300,000 or more depending on size, utility connections, and finish level.
These are planning ranges, not bids. Site conditions and utility strategy drive ADU budgets more than any other project type, which is why feasibility review comes first in our process.
