Celina, Texas sits primarily in Collin County, with a smaller portion of the city extending into Denton County. That split matters the moment you buy a home, register to vote, or enroll a child in school, because county affiliation determines your property tax jurisdiction, which county court handles legal matters, and sometimes which school district serves your address.
Before you commit to any Celina property, three things are worth confirming:
- Property tax jurisdiction: Which county appraisal district (Collin CAD or Denton CAD) assesses your parcel
- School district: Whether your address falls inside Celina ISD or a neighboring district
- Voting precinct: Which county’s elections office handles your registration

How Celina’s city limits sit across Collin and Denton counties
Most of Celina falls inside Collin County. The U.S. Geographic Names Information System lists the city’s primary location as Collin County, Texas, though the boundary also touches Denton County to the west. The city covers 48.216 square miles total, with 47.725 square miles of land area, and the county line runs through the western portions of the city limits.
Geographically, Celina sits about fifteen miles northwest of McKinney and twelve miles north of Frisco, placing it squarely inside the Dallas–Fort Worth metroplex. The Dallas North Tollway corridor runs to the city’s west, which is also where the Denton County portion of the city is concentrated.
“Celina is on State Highway 289 and Farm Road 455, fifteen miles northwest of McKinney and twelve miles north of Frisco in northwestern Collin County.” — Texas State Historical Association
For a precise boundary map, the City of Celina’s GIS portal and the respective county appraisal district websites are the authoritative tools. Never rely on a ZIP code or a neighborhood name to determine county; only a parcel-level lookup gives you the definitive answer.
What being in two counties means for residents and buyers
County affiliation is not just a trivia question. It has real financial and legal consequences that vary by address.
Property taxes are the biggest variable. Collin County and Denton County each set their own tax rates, and the taxing entities layered on top of the county rate (municipal utility districts, emergency service districts, hospital districts) differ by parcel. Two homes on the same street can carry meaningfully different effective tax rates if the county line runs between them.
Voting and courts follow the same logic. Your county determines your precinct, your county judge, your county commissioners, and which district court has jurisdiction over civil matters. Sheriff’s jurisdiction also follows county lines, though the Celina Police Department serves the city regardless of which county a property sits in.
County services such as road maintenance on county roads, county health programs, and county-issued permits (septic systems, for example) come from whichever county your parcel is in.
Here is a practical checklist before making an offer on any Celina property:
- Pull the parcel number from the seller’s disclosure or the county appraisal district website
- Confirm which county the parcel is in (Collin CAD or Denton CAD)
- Request the full list of taxing entities and their current rates
- Verify the school district and specific campus assignment for that address
- Check voting precinct registration requirements with the correct county elections office
Steps to take when evaluating a specific property:
- Search the address on the Collin County Appraisal District website (collincad.org) or Denton CAD (dentoncad.com)
- Confirm the taxing entities listed on the parcel record
- Run the address through the Celina ISD school zone lookup
- Ask the listing agent for the property’s legal description and survey
- Cross-reference with the City of Celina GIS map for boundary confirmation
Pro Tip: Confirm the county and school district by parcel number before making an offer, not after. A title company will catch errors at closing, but by then you may have already made financial decisions based on the wrong tax rate.
Celina’s population growth is one of the fastest in the country
Celina recorded 16,739 residents in the 2020 census. By mid-2025, that number had climbed to between 64,427 and 64,726, according to U.S. Census Bureau estimates. That is nearly a fourfold increase in five years.
| Year | Population | Source |
|---|---|---|
| 2020 | 16,739 | U.S. Census Bureau (decennial) |
| Mid-2025 estimate | ~64,427–64,726 | U.S. Census Bureau estimates |
| 2026 projection | 72,000+ | U.S. Census Bureau / local planning |
That kind of growth compresses what normally takes decades into a few years. County services, school capacity, and road infrastructure are all running to catch up. Buyers should factor construction timelines and phased utility rollouts into their purchase decisions, not just the sticker price of the home.
Which school districts serve Celina, and why your address determines your campus
Celina ISD is the primary district serving the city, headquartered at 205 S. Colorado, Celina, TX 75009, and officially classified under Collin County. The district covers most of the city, including portions that extend into Denton County.
In 2025, Celina ISD asked voters to approve approximately $2.3 billion in bond propositions to fund eleven new campuses and facility improvements. That bond reflects the scale of enrollment pressure the district faces. If you are buying in a new construction neighborhood, ask specifically when the nearest planned campus is scheduled to open, because current campuses are absorbing students from developments that were built anticipating future schools.
Steps to verify your school zone:
- Use the Celina ISD website’s address lookup tool
- Cross-reference with the Collin CAD or Denton CAD parcel record, which lists the school district
- Ask the listing agent or builder for a written school zone confirmation
- Contact Celina ISD directly at 205 S. Colorado if the address falls near a district boundary
A small number of addresses in the Denton County portion of Celina may fall under a neighboring district’s boundary. Always verify by address, not by subdivision name.
City government and the county offices you will actually deal with
Celina operates under a council-manager form of government. Mayor Ryan Tubbs leads the city council, and the city manager handles day-to-day municipal operations. The city provides police, fire, parks, and municipal utilities regardless of which county a property sits in.
County-level services are a different matter. Property appraisal, tax collection, county courts, and county road maintenance come from either Collin County or Denton County depending on your parcel.
“The typical home value in Celina is north of $500,000, according to the latest Zillow data, but that’s cheaper than Frisco and McKinney.” — Mayor Ryan Tubbs, via The Texas Tribune
Collin County Appraisal District (collincad.org) handles appraisal and tax records for the majority of Celina parcels. Denton County Appraisal District (dentoncad.com) covers the western portions. When you call either office, have your parcel number ready and ask specifically about: the assessed value, all taxing entities on the parcel, the current combined tax rate, and any exemptions you may qualify for (homestead, over-65, disability).
Collin College serves as the community college for all of Collin County, per Texas Legislature designation, so residents in the Collin County portion of Celina have access to that institution.
How to check which county a specific Celina address is in
This is a five-minute process when you know where to look.
- Go to collincad.org or dentoncad.com and enter the property address in the parcel search
- The result will show the county, the legal description, and all taxing entities
- If the address does not appear in one CAD, try the other — that tells you which county the parcel is in
- Open the City of Celina GIS map (available at celina-tx.gov) and locate the address to visually confirm the county boundary
- Note the school district listed on the CAD record and verify it against Celina ISD’s zone map
- Save or screenshot the parcel record — you will want it when reviewing the title commitment
Pro Tip: Ask the listing agent for the property’s legal description before your first showing. That string of text (subdivision name, lot, block, county) tells you the county instantly and saves a separate lookup.
Celina’s growth in 2024–2026 and what it means for county services
Celina was the fastest-growing city in the United States between July 2024 and July 2025, adding more than 12,710 residents and growing by 24.6%. Among U.S. cities with more than 20,000 residents, Celina ranked fourth in raw numerical growth during that period. CBS Texas also ranked Celina among the nation’s fastest-growing cities in the same cycle, alongside Princeton, Melissa, and Anna.
“Celina has grown substantially since 2020, adding tens of thousands of residents.” — The Texas Tribune, May 2026
That pace strains both Collin and Denton county services. Road projects, water and utility expansion, and school construction are all running simultaneously. Mayor Tubbs has publicly noted the infrastructure pressure, and a significant share of Celina residents work remotely, which softens some commute strain but does not reduce demand for roads, utilities, and schools.
Buyers moving to Celina in 2026 should budget for ongoing construction near new developments, variable permitting timelines, and the likelihood that some planned amenities (parks, retail, school campuses) will open on a phased schedule over the next two to four years. Check the city’s capital improvement plan at celina-tx.gov for neighborhood-specific timelines.
Key Takeaways

What the growth really means if you’re considering a move to Celina
Celina’s appeal is straightforward: newer homes at prices below Frisco and McKinney, strong schools, and a genuine small-town feel that is rapidly gaining big-city infrastructure. The county split is a detail most buyers overlook until closing, and that is exactly when it costs the most time.
The buyers who navigate Celina well are the ones who treat the county question as step one, not an afterthought. Confirming whether a property sits in Collin or Denton County takes five minutes online and can change your tax estimate by hundreds of dollars annually. With North Dallas growth reshaping the entire corridor, the window to buy before the next wave of infrastructure completion is narrowing. Families moving from out of state, including those relocating from Canada, often underestimate how much the county boundary affects their first year of ownership costs.
Kamilashayehomes can help you verify the details before you commit
Sorting out county lines, tax rates, and school zones on your own is doable, but it takes time and knowing which databases to trust. Kamilashayehomes works with buyers in Celina, Prosper, Frisco, and surrounding communities to confirm exactly these details during the property search, not after the offer is signed.
Kamila Shaye and her team pull parcel-level data, confirm taxing entities, and verify school zone assignments as part of the standard buyer process. For families moving from Canada to North Dallas, that county-level groundwork is especially useful when you are evaluating properties remotely. Browse current Celina listings or reach out directly at kamilashayehomes.com to get a property-specific county and school zone check before you make your move.
