Location, Lot and Layout! The THREE most important things in real estate. Yes, these things you can't change. And be glad because the Masson Ranch exemplifies the best of all of it! Not a thing to change with this spectacular ranch estate. Few and far between do you find a home where the house and the land are both spectacular! The kitchen is stunning with it's custom cabinets, granite counters and stainless appliances. Large center island work space and a great breakfast bar counter. Formal dining and living and the coveted open kitchen/family room combo. Large primary suite with luxurious bath and walk-in closet. Spacious secondary bedrooms and a grand hall bath. HUGE attached 2-car garage (extra deep). The property is extraordinary; 11 Mulberry trees canopy the lush lawns in the backyard. Barn, shop, shed and boat storage. Pool and vegetable/flower garden. HUGE paved side access and of course about 3/4 acres of blank slate to do what you want. Horses, vineyard, orchard, golf course! you name it! Now, the best part: On a quiet dead end st with orchards out the front, tranquility and privacy all around. On the NW side of Tracy, commute close to I580 and super close to the new shopping centers on the North side. Truly an exceptional property. Live Well!

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.
