School district boundaries in San Antonio do not follow neighborhood or city lines. Two homes on the same street can be in different school districts. Always verify school assignment by address using the district's boundary lookup tool. Major districts include NEISD, NISD, SAISD, Boerne ISD, and Comal ISD. Boundaries change occasionally, so verify before purchasing.
How Boundaries Work
School district boundaries in Texas are determined by county-level apportionment, not city or neighborhood boundaries. This means a street that forms a district line can put one side in a highly rated district and the other side in a lower-rated district. School attendance zones are even more granular, determining which elementary, middle, and high school a student attends within a district.
Major School Districts
North East ISD (NEISD) covers much of north-central and northeast San Antonio and is widely regarded as one of the top districts. Northside ISD (NISD) serves the northwest quadrant and is the largest district in the city. San Antonio ISD (SAISD) serves downtown and central areas. Boerne ISD covers the Hill Country communities. Comal ISD serves the northeast corridor toward New Braunfels. Each district has different boundary lines that do not align with city limits.
How to Verify
Always use the school district's official boundary lookup tool, available on each district's website. Enter the specific address you are considering. Do not rely on real estate websites, agent assumptions, or neighbor reports. If you are working with me, I will verify school assignments as part of my due diligence before you make an offer.
Boundary Changes
School district boundaries occasionally change due to population shifts, new school construction, and district rezoning. A home that feeds into a specific school today may be reassigned next year. Ask about any planned boundary changes when researching a property. Districts typically announce changes in the spring for the following school year.
How Boundaries Affect Home Values
School district assignment can affect a home's value by $30,000 to $50,000 or more. Homes in top-rated districts like Alamo Heights ISD, Boerne ISD, and portions of NEISD command significant premiums. Buyers should verify school district before falling in love with a home, as the difference between two districts on the same street can be hundreds of thousands of dollars in long-term value.
