Build an ADU!

Accessory Dwelling Units (ADU) provide much-needed housing units to our community. And in an effort to facilitate the construction of ADUs, the City offers pre-approved construction plans for a one-bedroom (720 SF) and a two-bedroom (960 SF) detached ADU. Designed as a craftsman bungalow, the plans feature a low-pitched, gabled roof with overhanging eaves and a front porch nestled under the roofline. Rooflines can be oriented east/west or north/south to optimize site layout and sun exposure for roof-mount solar.

The City offers expedited permitting for Accessory Dwelling Units. The typical review period is 4 to 6 weeks. City staff is available to help navigate the ADU permitting process. Please stop by the Community Development Department or call 707-961-2827 x111 to be connected to a planner.
