Stone Oak (78258): Where It Ends, Where NEISD Stops, and Why Bulverde Is a Different Deal

Stone Oak is a Bexar County submarket in ZIP 78258, sitting north of Loop 1604 along the US-281 corridor and zoned almost entirely to North East ISD. The confusion starts when buyers keep driving north on 281. Somewhere past Evans Road and Marshall Road, the subdivisions stop being Stone Oak and start being Bulverde — which is a different city, a different county (Comal), a different school district (Comal ISD), a different appraisal district, and in many cases a different electric and water provider. The house can still say "San Antonio, TX 78258" on the mail, and the listing agent can still call the area "Stone Oak," and none of that changes the tax bill or the high school your kid attends.

If you are shopping north of 1604, the single most useful thing you can do is figure out which side of the Bexar/Comal line a property sits on before you fall in love with it.

Where Stone Oak actually is

Stone Oak is not an incorporated city. It is a large master-planned area inside the City of San Antonio's northern ETJ and city limits, concentrated in 78258 with spillover into 78260 and 78259. Rough boundaries most locals use:

• South: Loop 1604, near the Stone Oak Parkway / Huebner interchange
• West: US-281, with Sonterra and Encino Park straddling the freeway
• East: Bulverde Road and the Wurzbach Parkway extension
• North: the Bexar/Comal county line, which runs roughly along Evans Road in the west and jogs around Timberwood Park in the east

Everything inside those lines is City of San Antonio, taxed by Bexar County, appraised by BCAD, and zoned to NEISD. That is the Stone Oak most people mean when they say Stone Oak.

The NEISD schools you are actually buying into

78258 is carved up between three NEISD high schools, and they are not interchangeable. Attendance zones get redrawn — check the NEISD boundary map for the specific address, not the subdivision name.

• Ronald Reagan HS (Legacy / Stone Oak core): the largest Stone Oak zone, feeds from Bradley MS and Tejeda MS
• Claudia Taylor "Lady Bird" Johnson HS (far north Stone Oak, near Hardy Oak and TPC Parkway): feeds from Lopez MS and Barbara Bush MS
• Winston Churchill HS (southern/western edge, closer to 1604 and inside the original Sonterra footprint): feeds from Bradley MS

Do not confuse NEISD (North East ISD) with NISD (Northside ISD). Northside is the district on the west side of town — O'Connor, Clark, Brandeis, Brennan. Stone Oak is NEISD. Every week someone writes an offer thinking their kid is going to Brandeis from a Stone Oak address, and they are not.

Where NEISD stops and Comal ISD starts

Drive north on 281 past the Stone Oak Parkway exit. Keep going past Evans, past Marshall. At some point — and the exact line is not visible from the road — you cross out of Bexar County into Comal County. The ZIP code often stays 78260 or even 78258 on the USPS side, but the school district flips to Comal ISD, and the zoned high school becomes Smithson Valley HS in Spring Branch.

The subdivisions most often mislabeled as "Stone Oak" that are actually Comal County / Comal ISD:

• Timberwood Park — Comal County, Comal ISD (Smithson Valley zone), 78260 mail
• Mystic Shores, Estates at Canyon Lake area — well north, fully Bulverde/Comal
• Copper Canyon, Johnson Ranch, Vintage Oaks — Bulverde city or ETJ, Comal ISD
• Indian Springs, River Crossing — Comal County

If a listing says "Stone Oak area" but the address is Bulverde, Spring Branch, or an unincorporated Comal address, you are not in NEISD.

Two appraisal districts, two tax bills

This is where the money lives. Property tax in Texas is the sum of overlapping jurisdictions — county, city, school district, and special districts — and those stack differently on each side of the line.

Item	Stone Oak (Bexar)	Bulverde-area (Comal)
Appraisal district	BCAD	Comal CAD
County	Bexar	Comal
City	City of San Antonio (most)	Bulverde, Spring Branch, or unincorporated
School district	NEISD	Comal ISD
Homestead filing	Form 50-114 to BCAD, deadline April 30	Form 50-114 to Comal CAD, same deadline
Protest hearing	Bexar ARB, May–July	Comal ARB, May–July

Total effective rates are usually lower in Comal County because you often escape city taxes if you are in the ETJ or in unincorporated territory, and Comal ISD's rate tends to run lower than NEISD's. That can be offset by MUD (municipal utility district) or PID (public improvement district) assessments in newer Comal subdivisions — Vintage Oaks and Johnson Ranch both have additional district assessments that show up as separate line items. Pull the actual tax bill from the CAD's public search before you assume you are saving money.

Homestead exemption (Texas Tax Code § 11.13) does not transfer. If you move from a Stone Oak home to a Bulverde home mid-year, you file a new Form 50-114 with Comal CAD. If you want to fight the appraised value, that is Texas Tax Code § 41.41 and it happens at the county that appraised it — you cannot take a Comal protest to Bexar's ARB.

Utilities are not the same company

Inside Stone Oak proper:

• Electric: CPS Energy
• Water + sewer: SAWS
• Gas: CPS Energy (where available; a lot of Stone Oak is all-electric)

Cross into Comal County and this changes. Electric is often GVEC (Guadalupe Valley Electric Co-op) or Pedernales Electric Co-op, not CPS. Water is frequently a private utility — Canyon Lake Water Service, GBRA, or a subdivision-run system — with its own rate schedule and its own outage response. Sewer in unincorporated Comal is often septic, not municipal, which means a septic inspection at purchase and maintenance responsibility forever. Ask the seller which utilities serve the property in writing. TREC's OP-H Seller's Disclosure Notice has a utilities section — read it, do not skim it.

The 281 and 1604 reality

Stone Oak's core value proposition was "close to 281, quick downtown commute." That held up better 15 years ago than it does now. TxDOT's US-281 North expansion added toll-free main lanes and toll-managed express lanes through the 1604 interchange, and the 1604 expansion to a full freeway between 281 and I-10 is ongoing in phases. Current reality:

• Morning southbound on 281 from Evans to 1604 is reliably 20–35 minutes in rush hour
• 1604 westbound between 281 and I-10 West is the worst segment in the submarket during construction
• The Wurzbach Parkway extension has genuinely helped east-west trips to the airport and Fort Sam Houston
• If you work at JBSA-Randolph on the east side, Stone Oak is a long commute — Schertz or Cibolo is closer
• If you work at JBSA-Fort Sam Houston or the medical center, Stone Oak via Wurzbach Parkway or 281-to-410 is workable

What most people get wrong

• Trusting the mailing address. A Bulverde home can have a "San Antonio, TX 78258" USPS address. The USPS ZIP tells you nothing about school district, county, or city taxes. Verify with the county CAD's property search.
• Assuming all of 78258 is Reagan HS. It is not. NEISD has rezoned multiple times as Johnson HS opened and grew. Pull the current attendance zone for the specific street address from NEISD's boundary tool.
• Mixing up NEISD and NISD. NEISD is North East — Stone Oak, Churchill, Reagan, Johnson, MacArthur. NISD is Northside — Brandeis, Clark, O'Connor, Brennan. They do not overlap in Stone Oak.
• Ignoring MUD/PID assessments in Comal subdivisions. The sticker tax rate looks lower, but Vintage Oaks, Johnson Ranch, and several newer developments carry additional district assessments that can close most of the gap. Get the full tax bill, not the headline rate.
• Buying on septic without an inspection. A standard home inspection does not inspect the septic system. In unincorporated Comal, pay for a separate septic inspection by a licensed installer.
• Not filing homestead after a move. Moving within the metro does not transfer your exemption. File Form 50-114 with the correct CAD — BCAD or Comal CAD — by April 30 of the year after you occupy.

If you are shopping the corridor

Decide which side of the line you want before you tour. If NEISD schools and SAWS/CPS service are the reason you are moving, stay south of the Bexar/Comal boundary and confirm the address is in Bexar County on BCAD's property search. If you want larger lots, a lower nominal tax rate, and do not mind septic and a different school district, Bulverde and Spring Branch are legitimate options — just underwrite them as Comal County homes, not as Stone Oak.
