About Our ADU Construction & Garage Conversions Service
Accessory Dwelling Units are one of the smartest investments a San Jose homeowner can make, and California's streamlined ADU laws make them more attainable than ever. We build detached backyard ADUs, attached units, junior ADUs, and garage-to-living-space conversions -- handling design, San Jose planning and building permits, utility connections, and the full build. Whether you want a private space for family, a home office, or rental income in one of the country's tightest housing markets, we manage the entire process and deliver a finished, code-compliant, independently metered unit.
