Thinking about building an ADU?
Find out if your property may qualify for an ADU, Junior ADU, Garage Conversion, or Home Expansion — we'll review it for you.
What we build
Six ways to unlock your property.
Every project starts with what California zoning allows on your lot — then we design around your goals, budget, and timeline.
Why build
One structure. Many futures.
An ADU is the most flexible asset you can add to your property — income, family housing, workspace, or all of the above.
Generate Rental Income
Many California ADUs return $1,800–$3,500/mo in rent.
Increase Property Value
Add square footage that compounds long-term equity.
Multi-Generational Housing
Bring family closer with privacy and independence.
Home Office Space
A dedicated, quiet workspace separated from the home.
Guest Accommodations
A real second home for visitors — not a spare room.
Flexible Living Solutions
One structure, many futures: rental, family, or retreat.
