Collin County, Texas - County Development Fees
Collin County | County | County seat: McKinney | Dallas-Fort Worth Metroplex (north) | US-75 / Sam Rayburn Tollway corridor | FIPS 48085
This page covers development fees for unincorporated Collin County - the areas regulated directly by the county, not by an incorporated city. Texas counties have no zoning authority, so Collin County's developer-facing fees run through development permits, subdivision and plat review, On-Site Sewage Facility (septic) permitting, floodplain review, and building re-inspection rather than through zoning applications. The amounts below come from the county's adopted Fee Schedule for FY 2026 (fiscal year beginning October 1, 2025; document print date September 29, 2025). Construction inside the county's incorporated cities - McKinney, Plano, Frisco, Richardson, Allen, and others - is permitted by those cities and carries city fees, which are separate from this county schedule. Verify current amounts with Collin County Development Services before relying on them.

Impact Fees - Does Not Apply
Texas counties generally lack authority to impose impact fees under Texas Local Government Code Chapter 395, which conditions impact-fee imposition on municipal-style political subdivisions. This is a documented closed-search outcome rather than a coverage gap: the adopted Collin County Fee Schedule (Development Services section) contains zero Chapter 395 impact-fee line items, the county operates no water or wastewater utility that could support water or sewer impact fees, and county development-cost recovery instead runs through development permits, subdivision and plat review, OSSF review, and subdivision road and street performance bonds under Local Government Code 232.004.
This is consistent with the Texas general-law county model seen on ZoneFee's other county pages - see Denton County. For the statewide framework that applies to Texas cities, see the impact fees guide.
Utility Tap Fees - Not Administered
Collin County does not operate a water or wastewater utility, so it charges no water or sewer connection or tap fees. Retail water and sewer service in the county is provided by the incorporated cities (McKinney, Plano, Frisco, Allen, and others), by Special Utility Districts and Water Supply Corporations, and by the regional wholesale provider the North Texas Municipal Water District (NTMWD) - each a separate political subdivision with its own charges. The county's only water-related fees are the On-Site Sewage Facility (septic) review and inspection fees and the floodplain development review, both shown in the development-fee tables above. Connection and tap fees belong on the relevant city, district, or authority record rather than on this county page.
Special District Fees - Not Administered
Collin County contains numerous Municipal Utility Districts (MUDs), Special Utility Districts (SUDs), Water Supply Corporations, and Public Improvement Districts (PIDs). Each is a separate political subdivision that levies its own developer-side fees and assessments, which belong on dedicated records rather than on the county jurisdiction page. This is a documented closed-search outcome: the adopted Collin County Fee Schedule (Development Services section) contains no district (CDA/MUD/PID/SUD) developer-side fee line items. The county's fee surface is limited to development permit, subdivision and plat, OSSF, floodplain, and environmental-health fees.
Coverage Notes - What This Page Does Not Cover
Per ZoneFee's Partial-Verified Publication Standard, the items below were not closed on this page with a fixed fee amount traceable to a dated or byte-stable official source document. They are disclosed here rather than estimated, paraphrased from a non-official source, or omitted silently. These items remain under limited-coverage review until these gaps are closed from official sources.
City fees inside incorporated Collin County
This page covers unincorporated-area, county-administered fees only. Building and construction permit inspections inside the incorporated cities of Collin County - and inside those cities' extraterritorial jurisdiction where an interlocal agreement applies - are handled by the cities, not the county. For city-level development fees, see the individual ZoneFee city pages for McKinney, Plano, Frisco, and Richardson.
Performance bond amounts
The subdivision road and street performance bond is set by the Commissioners Court on a per-project basis, capped at the estimated cost of constructing the roads and streets, so no fixed dollar amount is published or shown here.
Adjacent counties
Collin County's county-to-county adjacency was not established against a captured official GIS or Census boundary dataset in this review, so no formal adjacency list is presented. Collin County borders Grayson, Fannin, Hunt, Rockwall, Dallas, and Denton counties.
Proffers
Cash proffers are a Virginia statutory instrument under Virginia Code Section 15.2-2303 with no Texas counterpart. Texas county developer contribution runs through subdivision platting (Local Government Code Chapter 232), road and street performance bonds (Local Government Code 232.004), and standard right-of-way and easement dedication, not cash proffers. Closed-search outcome: this fee family does not apply to this jurisdiction.

Texas counties generally levy no Local Government Code Chapter 395 impact fee, Collin County operates no water or sewer utility, and district (MUD/SUD/PID) fees are levied by the individual districts - each is a documented closed-search outcome rather than an omission. Texas has no cash proffer regime. Verify all current rates directly with Collin County before relying on this data for land acquisition, project budgeting, or any financial decision.
