Zoning
R-R
Rural Residential Zone
The Rural Residential Zone provides for large-lot rural homesites within existing rural communities where full urban services are not available or expected and in urban communities where rural residential densities already exist. Lots will generally have sufficient area to allow for individual water supply, sewage disposal, and storm water drainage. Typically, areas in this zone will contain parcels too small to support significant commercial agriculture, yet are suitable for residential use without undue detriment to the agricultural productivity of San Joaquin County. This zone implements the Rural Residential land use designation of the General Plan.
