Why Build an ADU

Unleash your home's potential.

Generate rental income — many clients cover their mortgage with one tenant.

No extra parking required — recent CA laws removed this barrier.

Lower permit fees — state regulations have reduced city fees significantly.

Faster approvals — ministerial approval means no discretionary hearings.

Increased property value — ADUs typically add 20–30% to home resale value.
