ADU Types We Serve
We build every type of ADU California allows:
Detached ADU — A standalone unit built separately on your property. Full custom design, site planning, and structural engineering included.
Attached ADU — Connected to your existing home with its own entrance, kitchen, and bathroom. Perfect when yard space is limited.
Garage Conversion — Transform your existing garage into a fully permitted living space. We evaluate your structure and handle all code upgrades.
Junior ADU (JADU) — A compact unit up to 500 sq ft created within your existing home. The most affordable ADU option with no new foundation required.
Existing Floor Conversion — Convert an underused floor of your home into a self-contained ADU. We maximize your existing layout with minimal disruption.
