​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 preapproved 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.

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.
