ADU
ADU Construction
The highest long-term ROI of any addition.
ADUs are the fastest-growing residential category in 2026 for a reason: they pay for themselves. We match you with firms that build to code and to rent, detached, attached, or garage conversion, with the local ordinance know-how that makes or breaks the project.
Detached 400–800 sq ft: $100k–$250k. Garage conversions: $50k–$120k. Avg build ~$180k. Figures are 2026 USA benchmarks compiled from Angi, Houzz State of the Industry, the Remodeling Cost vs. Value report, and NARI/NKBA member data, re-verified quarterly (last checked 2026-06).
