What drives ADU cost up or down in Rancho Cordova?
Rancho Cordova runs roughly 2% below the central-Sacramento baseline, making it one of the more cost-efficient places in the region to add an ADU.
Rancho Cordova lots: Anatolia and the Sunridge tracts are new-construction flat — easy to side a unit on, HOA permitting. Old Rancho Cordova's deeper pre-2000 lots near light rail give more siting freedom for a detached build.
Local permitting: Rancho Cordova has its own Building & Safety Division (4 ft setbacks, 16 ft height). The split that matters: the newer Sunridge-area subdivisions like Anatolia layer HOA review on top of the city's, while Old Rancho Cordova's older, larger lots near the light-rail corridor have far fewer restrictions.
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.
