Residential Land for Sale in Tucson, Arizona
15820 & 15840 S Black Oak Ave, Tucson, AZ 85736
This property consists of two adjoining lots totaling 2.28 acres at 15820 and 15840 S Black Oak Ave in Tucson, Arizona. Located in the Diamond Bell Ranch area, the land is surrounded by undeveloped Sonoran Desert with open views and distant mountain ranges. The terrain is mostly flat, with sandy soil and native desert vegetation including mesquite trees, prickly pear, cholla cactus, and low desert grasses. A faint, older access path runs across the property.
Access is available by dirt roads and requires careful navigation. The route follows Highway 86 (Ajo Way) west from Tucson, then south on Sarita Mountain Road for approximately 15 minutes to Big Run Avenue. The final stretch to Black Oak Avenue is rough and includes sandy sections and a creek bed crossing, making a 4WD or AWD vehicle advisable. Signage is limited, and GPS or detailed maps are recommended.
There are no public utilities on the property. Power would need to be provided by solar or a generator, as the nearest COOP electric line is located near Diamond Bell Ranch Road and would require a costly extension. Water would need to be supplied by a private well, and a septic system can be installed for wastewater. Neighboring homes are sparse, with one located near the southeast boundary and others spread across the area. Cell service is very limited and generally only available closer to the main highway.
