What drives ADU cost up or down in Cameron Park?
Cameron Park runs roughly 6% above the central-Sacramento baseline, driven mostly by site conditions and finish expectations in this submarket.
Cameron Park lots: Cameron Estates and central Cameron Park lots are generous and flat enough for a straightforward full-size detached build.
Local permitting: Cameron Park permits through the El Dorado County Planning & Building Department. Larger lots comfortably fit a full detached ADU; many parcels are on septic, and the Cameron Park Airport overlay can affect a small subset of properties, which we verify during feasibility.
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.
