Collin County, Texas

Collin County is no longer just a suburb of Dallas. It's become one of the most dynamic growth corridors in the country, home to 24 Fortune 500 headquarters, a population that's added nearly 200,000 residents since the 2020 Census, and a land market where demand consistently outpaces supply. For land buyers, that creates a specific kind of opportunity and a specific kind of risk. Prices have appreciated steadily, with some estimates placing year-over-year growth at 45% for Collin County land. But that appreciation isn't uniform. A 10-acre tract east of Princeton and a 10-acre tract west of Prosper are two completely different investments, even though they're in the same county. This guide breaks down what you need to know before buying land in Collin County, from zoning and water access to school districts and growth corridors.

Residential Acreage (1–10 Acres) The most active segment. Buyers are typically families looking to build a custom home on acreage, often in a specific school district. Common in Celina, Melissa, Prosper, and Anna. Expect to see 1-acre minimums in many subdivisions, with unrestricted tracts of 5–10 acres available in more rural areas. Farm & Ranch Tracts (10–50+ Acres) Available primarily in the northern and eastern parts of the county Blue Ridge, Farmersville, Princeton, and unincorporated areas. Many carry ag exemptions. These are attractive to both lifestyle buyers and investors watching the growth corridor push north and east. Development Parcels Collin County's growth has created strong demand for development-ready land. Parcels with approved concept plans, completed water studies, or existing engineering are in high demand from builders. If you're evaluating a development parcel, pay close attention to which city's ETJ it falls within, as entitlement requirements vary significantly by municipality. Commercial Land Commercial parcels along the US 380 corridor, near the Dallas North Tollway extension, and along US 75 are seeing strong demand driven by the same population growth that's pushing residential values. Retail, medical, and mixed-use developments are actively seeking sites.

Water access is one of the most important factors in a Collin County land purchase, and it varies dramatically by location. Municipal Water Cities like McKinney, Frisco, Prosper, Celina, Anna, and Princeton provide municipal water within their city limits and sometimes within their ETJ. The North Texas Municipal Water District (NTMWD) is the regional wholesale provider that supplies water to most of these cities. If a property is within city limits or an area served by a Municipal Utility District (MUD), municipal water is typically available or can be extended. Municipal Utility Districts (MUDs) Collin County has dozens of MUDs, particularly in areas of active development around Celina, Prosper, and Princeton. MUDs are political subdivisions that fund infrastructure (water, sewer, drainage, roads) through bond issuances. If you're buying in a MUD, understand that your property tax rate will include the MUD tax, which can add $0.50–$1.50+ per $100 of assessed value on top of other taxing entities. Some of the active MUDs in Collin County include Collin County MUD No. 1 (Light Farms area near Celina), North Collin Special Utility District (Melissa area), and numerous others associated with specific developments. Well Water In more rural areas, particularly east of US 75 near Blue Ridge, Farmersville, and parts of Princeton, well water may be the primary option. The Trinity Aquifer underlies much of Collin County and provides adequate supply for residential wells in most areas. However, well depth, water quality, and flow rates vary by location. Always get a well inspection or drill test before closing on land where well water is the planned source. Septic vs. Sewer If you're outside a city's sewer service area, you'll need an on-site sewage facility (septic system). Collin County Development Services handles OSSF permitting and requires a site evaluation to determine soil suitability before a permit is issued. Not all soils support conventional septic systems and some properties may require engineered aerobic systems, which are more expensive to install and maintain. Electric Service Collin County is served by several electric providers. In more rural areas, you may be served by a cooperative like CoServ Electric (common in western Collin County near Celina and Prosper) or Grayson-Collin Electric Cooperative (northeastern areas). Within city limits, Oncor is typically the transmission and distribution provider with your choice of retail electric providers. Internet & Broadband This matters more than people expect, especially for remote workers. Urban and suburban areas have robust broadband through providers like AT&T Fiber and Spectrum. Rural areas can be more limited. Starlink has become a viable option for rural tracts, but verify coverage and speeds for your specific location before assuming you'll have adequate connectivity.

Understanding where Collin County is heading matters as much as understanding where it is today. Three major infrastructure projects are reshaping the county's geography. US 380 Expansion US 380 is the primary east-west corridor across Collin County, connecting Prosper, Frisco, McKinney, and Princeton. TxDOT is expanding the highway from a two-to-four lane state highway into an eight-to-ten lane freeway in multiple segments. In the Princeton area, a new-location bypass will route the freeway north around the city. This is a multi-year, multi-billion-dollar project that will fundamentally change accessibility and land values along the corridor. The expansion has been separated into five independent segments, each advancing on different schedules depending on traffic needs and funding. Right-of-way acquisition began in early 2025 for the Princeton segment, with construction anticipated to let in 2027. Collin County Outer Loop The Outer Loop is a planned 53-mile transportation facility connecting major highways including I-35, US 377, the Dallas North Tollway extension, SH 289, US 75, SH 121, US 380, and I-30. In November 2025, the county opened a new 15-mile segment connecting the Dallas North Tollway in Celina with US 75 north of Melissa. This was a $62.7 million project built entirely with local bond money, no state or federal dollars, and completed ahead of schedule. Additional segments are planned to connect US 380 in Farmersville to FM 6 in Josephine and SH 121. The Outer Loop is designed with future expansion in mind, including additional lanes. A new Collin County Northeast Freeway study is also underway, looking at a proposed 10-mile freeway from SH 121 to the future US 380 Freeway. For land buyers, the Outer Loop is a leading indicator of where development will follow. Properties along or near the planned route, especially at future interchange locations are positioned for significant value appreciation. Dallas North Tollway Extension The northward extension of the Dallas North Tollway continues to push through Prosper and into Celina, bringing with it major commercial development, master-planned communities, and rising land values. If you're looking at land west of US 75 and north of Prosper, the tollway extension is the single biggest factor influencing values. What This Means for Buyers The growth corridors are moving north and east. Celina, Melissa, Anna, and Princeton are the current frontier of development. Land prices in these areas have already begun to reflect that reality, but there's still a meaningful spread between land values in established areas and land in the path of growth. The infrastructure investments underway will compress that spread over the next 5–10 years.

Before closing on any land purchase in Collin County, verify the following: 1. Jurisdiction & Zoning Is the property inside city limits, in a city's ETJ, or in unincorporated county land? If in an ETJ, which city? What are their subdivision and building permit requirements? Are there any deed restrictions, plat notes, or HOA covenants? If unincorporated, review Collin County Subdivision Regulations. 2. Water & Utilities Is municipal water available, or will you need a well? Is city sewer available, or will you need a septic system? Has a soil study been done for septic suitability? Which electric provider serves the area? What internet/broadband options are available? 3. Flood & Drainage Is any portion of the property in a FEMA-designated floodplain? If developing 5+ acres or 50+ lots, a flood study may be required. Check FEMA flood maps at fema.gov/flood-maps. 4. Survey & Access Do you have a current survey? If not, get one. Does the property have legal access via a public road? Is there adequate road frontage (minimum 100 feet required for subdivisions)? Are there any easements (utility, pipeline, access) crossing the property? 5. Agricultural Exemption Does the property currently carry an ag exemption? If so, what use qualifies it? Will you continue that use? If you change the use, calculate the rollback tax liability before closing. 6. Environmental & Title Are mineral rights included or reserved? Are there any environmental concerns (previous commercial use, underground storage tanks)? Get title insurance and review the title commitment carefully. 7. Financial Land loans typically require 20–30% down with 15–20 year terms. Construction-to-permanent loans can roll land purchase and building into one loan. Some sellers offer owner financing with more flexible terms. Texas Farm Credit and local community banks are common lenders for land transactions.
