Stone Oak is a large master-planned area on San Antonio’s north side, inside the city limits — it’s not its own municipality, even though it’s often talked about that way. The main ZIP codes are 78258 and 78259. Planning dates to the 1980s, when it was laid out as a commuter suburb on former ranchland; since then it’s grown into a substantially built-out community with its own identity.

What’s Actually Here

Stone Oak includes a mix of gated and non-gated subdivisions — The Vineyard, Canyon Diablo, Preserve at Stone Oak, and Preserve at Walnut Springs among many others — on lots running from roughly 0.15 acre up to more than half an acre in the higher-priced enclaves. Architecture leans traditional, transitional, and Mediterranean, with brick, stone, and stucco exteriors common throughout. Stone Oak Parkway is the main commercial and medical corridor, home to the Parman Branch Library and a wide mix of retail and dining. North Central Baptist Hospital anchors medical care here with emergency, surgical, oncology, and neonatal intensive care services. US-281 and Loop 1604 are the two main routes in and out, connecting to The Shops at La Cantera, The Rim, and downtown — north-side traffic has grown with the population, so it’s worth planning routes around peak hours. HOAs are common throughout Stone Oak’s subdivisions, governed under Chapter 209 of the Texas Property Code, typically covering exterior appearance, landscaping, and assessments that fund shared amenities like pools and gated entries. A meaningful part of Stone Oak also sits within the Edwards Aquifer Recharge Zone, which can bring extra review into play for pools, additions, or other outdoor projects — worth checking early if you’re planning to build.

Home Prices and the Current Market

The median sale price over the three months ending July 2026 was $509,826, essentially flat year-over-year. What’s shifted more is inventory and negotiating leverage: active listings in the 78258 ZIP were up roughly 50% year-over-year, giving buyers meaningfully more to choose from. Homes have been taking a median of 59 days to sell (up from 32 days in 2025) and closing around 98.3% of list price — buyers are negotiating a couple of percent off asking on average. Figures like these shift month to month, so treat this as a snapshot rather than a fixed number.

Schools

Stone Oak is served by North East Independent School District. Named campuses associated with the area include Stone Oak Elementary, Johnson High School, Churchill High School, LEE High School, and MacArthur High School — exact assignment depends on the specific subdivision, so I’d confirm the zoned campuses for any address before assuming.

Taxes and What Else to Check

The City of San Antonio’s municipal rate is $0.541590 per $100 of value; the full combined stack for a Stone Oak property — NEISD, Bexar County, University Health System, Alamo Community College, Bexar County Road & Flood, and the San Antonio River Authority — typically works out to roughly $2.267 per $100. For 2025, homestead exemptions run $140,000 at the school-district level, with an additional $60,000 available for qualifying seniors and disabled homeowners; I’d confirm current amounts with the Bexar Central Appraisal District, since exemption rules update periodically. Methodist Hospital Stone Oak and North Central Baptist Hospital give the area a real medical-employment anchor beyond just the commuter base.

With inventory up meaningfully this year, buyers have more real leverage in Stone Oak than they’ve had in a while — happy to walk through what that means for a specific home or subdivision. Call or text any time.
