What drives ADU cost up or down in Woodland?
Woodland runs roughly 3% below the central-Sacramento baseline, making it one of the more cost-efficient places in the region to add an ADU.
Woodland lots: Spring Lake's large newer lots are the clean detached-build territory. The older downtown grid runs deep with existing garages, which is where Woodland's low conversion cost comes from.
Local permitting: Woodland's Community Development Department reviews ADUs in Yolo County under the standard 4 ft setbacks and 16 ft height limit. The two ends of town read differently: the historic downtown grid is full of older structures and garages that convert well, while newer Spring Lake lots are larger and flatter for a ground-up build.
The single biggest cost lever is size: keeping a unit under 750 sq ft exempts it from local impact fees. Site conditions (slope, soil, utility runs) and finish level move the rest.
