Sacramento ADU Cost by Neighborhood
2026 cost-per-square-foot ranges for a typical 600 sq ft new-build ADU, plus the median permit fee and rental demand for each Sacramento neighborhood. Midtown and East Sacramento command premium rents but also have tighter lots and historic-district overlays that raise design costs. Suburban neighborhoods like Natomas and Arden-Arcade offer larger lots, faster permitting, and a more straightforward path for detached new-builds.
