What drives ADU cost up or down in Placerville?
Placerville build costs track the central-Sacramento baseline closely — the price differences you'll see come from your lot and finish level, not the city.
Placerville lots: Smith Flat and Gold Hill parcels are larger and sloped; historic downtown lots are tighter with added design review.
Local permitting: Placerville ADUs permit through the City of Placerville or the El Dorado County Building Department depending on the parcel. Gold Country lots can involve slope, septic, well, and historic-district review downtown, all scoped before the bid so there are no surprises.
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.
