Where Utilities and School Districts Change at City Lines

Does your San Antonio area name tell you the utility and school district?

We constantly see new residents confused by how local borders work.

If you are moving to San Antonio, assuming your area name dictates your services is a very easy mistake to make. Two brand-new apartment communities located just a mile apart might sit in completely different utility territories.

Bexar County contains over a dozen independent school districts. City limits simply do not match up with these educational or utility boundaries.

Finding your san antonio electric provider by address is the only reliable method for setup. We confirm the provider and school district for every building on your shortlist.

Here is how the system works and the reason it matters for your budget.

No retail electric choice

No board address has retail electric choice. The provider is set by the address.

Electric providers on the board

We track utility data daily as a professional service team because providers change drastically just outside the city center. A home in San Antonio typically relies on CPS Energy for power. New Braunfels Utilities (NBU) serves most addresses in Comal County.

Provider	Board addresses (Oct 25, 2026)
CPS Energy	84
New Braunfels Utilities (NBU)	19
GVEC	4
Seguin Electric	1
PEC	1
Bandera EC	1

A common comparison is cps energy vs nbu because their service borders overlap near the county line. CPS Energy currently charges a rate of roughly 12.5 cents per kilowatt-hour as of 2026. NBU structures its bills differently by charging a $22.80 base monthly service fee and bundling electric with water.

Co-ops like GVEC serve the more rural edges near Guadalupe County. We see these base fees impact a property budget immediately. Co-ops like GVEC carry a mandatory $25 monthly floor fee regardless of how much power you use. Knowing these details prevents billing surprises.

Water

We check your specific water utility because billing formats change at the city limits. SAWS (San Antonio Water System) supplies water and wastewater services to over two million customers across the metro. NBU manages water for New Braunfels residents directly on the same bill as their electricity.

Some master-planned suburbs run their own independent water utilities. Water at Fair Oaks Ranch addresses is still being confirmed on our end.

You will encounter three main ways properties handle water costs:

• Direct utility billing: You pay SAWS or NBU directly.
• Sub-metered billing: The property measures your exact usage and adds it to your lease.
• Allocated billing: The building divides the total property bill among residents based on square footage.

Checking the community fee sheet prevents surprises on move-in day. In 2025, SAWS reported a record low of 111 gallons per capita per day due to strict conservation rules. Drought restrictions are a very real factor in South Texas.

School districts as facts

We list the exact school district as a fact for each building on our board. Searching for your school district by address san antonio ensures accurate zoning. You will find a lookup link on each listing so you can verify the boundary yourself.

We never rate or rank schools on our platform. Examples from our board:

• Far Northwest San Antonio: Northside ISD, by address
• New Braunfels: Comal ISD (16 board buildings) and New Braunfels ISD (4), by address
• Other areas: North East ISD and others, by address

Northside ISD enrolled over 98,000 students in 2026, making it the largest in the region. A single street can easily divide two massive districts.

If the school district matters to you, tell our team and we will confirm it for every building on your list.

Why it matters for your budget

We highlight these differences because utility providers directly affect your bottom line. Different companies enforce different rates, initial deposit rules, and base fees.

A detached build-to-rent home in GVEC co-op territory might require a larger upfront deposit than an apartment on CPS Energy. CPS Energy will often waive its deposit if you provide a guarantor or show excellent credit.

Comparing Base Service Fees

Provider	Monthly Base Fee (2026)	Billing Structure
CPS Energy	Variable by usage	Electric and gas only
NBU	$22.80	Electric, water, and sewer bundled
GVEC	$25.00	Electric only

You might pay significantly more for electricity in August depending on which provider sets your rate. We include utility notes in true monthly where we have reliable figures.

The 2027 electric choice bill

We monitor state legislation to see if retail choice will ever reach our local properties. In August 2026, Gov. Abbott announced a plan to open the electric market tied to a 2027 bill. This situation is strictly watch-only right now.

Municipally owned utilities like CPS Energy and NBU are currently exempt from Texas deregulation. Nothing changes at board addresses unless a new law passes and officially takes effect. We will update our pages immediately if that happens.

How to check an address yourself

We recommend verifying the exact address through official county or utility portals. You can follow these steps to confirm your services:

1. Ask the leasing office which electric and water providers serve the unit.
2. Check the provider’s service-area lookup with the full address.
3. Use the school district’s address lookup tool.
4. Compare with what we list on your shortlist.

Using the Bexar County Appraisal District (BCAD) property search is a great way to verify the exact jurisdiction. The Texas Education Agency (TEA) also provides a helpful district locator map.

Why lines and names don’t match

We frequently see confusion because San Antonio area names like Far Northwest or the South Side are entirely informal. City limits, utility service areas, and school district boundaries were drawn separately over many decades.

Developers often build new communities in Extraterritorial Jurisdictions (ETJs) just outside the city limits. A building marketed with a San Antonio area name might sit inside another town’s limits or a different school district.

Checking the specific address is the only way to know for sure.

The Border Effect

This boundary overlap matters most at the edges of the metro where Bexar County meets Comal, Guadalupe, and Kendall counties. The same issue applies inside San Antonio where several distinct school districts share the city map.

What we check for each building

We perform a thorough check to remove the guesswork from your search. The verification process covers the following details for every property:

• Electric provider and whether there is any retail choice (there is not at board addresses)
• Water and sewer provider, or whether the lease bills it
• School district, with a verification lookup link
• City limits, which dictate trash collection fees and emergency services

You can compare buildings on your shortlist using these verified facts.

Next steps

We suggest reviewing our guide on setting up utilities once you know your assigned providers. This resource covers deposit waivers, connection fees, and exact timing.

Scheduling utility connections ahead of time guarantees a smooth transition. The leasing office can usually verify if your chosen dates align with local rules.
