Absolutely incredible property for sale, not just a house, but a property! Sitting on 1.5 Acres in the Santos Ranch neighborhood, the main home was expanded from 1890 to 2651 sqft in 2021 with TWO Primary Suites and is impeccably upgraded throughout. You'll love the open floor plan, antique hickory floors, stone fireplace and granite counters, the huge shower and so much more. Out the backd you'll be shaded under a large covered patio with 3 ceiling fans installed for those hot summer days. Nearby ou'll find the crystal clear pool that was recently replastered and the pool equipment all replaced next to a large pergola for additional shade. Up on the roof there are two solar systems, a 11kw set of panels owned free and clear and a 5kw set that is leased. That's the main home, and probably not enough words to do it justice, but there's also the ADU on the back half of the property separated by fencing and with it's own street entrance on Hansen. The ADU is 1299 Sq Ft and lives like a 3/2 home, although technically on paper it's 2/2 plus a den. It will be delivered vacant but is currently tenant occupied. Also noteworthy is that this ADU was built before the code changed limiting ADUs to 1200 sq ft, so this one's grandfathered in. There's so much more to love than I can type!

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.
