Fort Mill, South Carolina, has become one of the most desirable places to live in the Charlotte metropolitan area. With its growing population, excellent schools, and proximity to Charlotte, it's easy to understand why so many people want to build a home here.
However, before purchasing land or starting construction, there's one major expense homeowners should understand: development impact fees.
What Are Impact Fees?
Impact fees are one-time charges imposed on new construction to help fund public infrastructure needed to support a growing community.
As more homes are built, communities need additional schools, fire protection, parks, and public facilities. Rather than funding all these improvements through existing taxpayers, local governments collect impact fees from qualifying new developments.
In Fort Mill, these fees can add tens of thousands of dollars to the cost of building a new home.
How Much Are Impact Fees in Fort Mill?
As of October 2026, the published impact fee for a new single-family home within the Fort Mill School District is $29,640.
This school impact fee was adopted by York County Council in April 2025 and applies to new residential construction throughout the Fort Mill School District, including properties outside Fort Mill's town limits.
For homes located inside the Town of Fort Mill, additional municipal impact fees apply.

These figures are based on York County's school impact fee schedule and the Town of Fort Mill's municipal impact fee schedule effective June 1, 2025.
What If You're Building Outside Fort Mill Town Limits?
One common misconception is that building outside Fort Mill's town limits eliminates impact fees.
Unfortunately, that isn't necessarily the case.
If your property is located in unincorporated York County but remains within the Fort Mill School District, you are still subject to the $29,640 school impact fee.
However, properties outside town limits are not subject to the Town of Fort Mill's additional $2,963 municipal impact fees.
For example:
Inside Fort Mill town limits: $32,603 in combined impact fees.
Outside town limits, within Fort Mill School District: $29,640 in school impact fees.
The important distinction is that impact fees depend on both your property's municipal jurisdiction and its school district.
A Fort Mill mailing address does not automatically mean your property is inside the town limits or the Fort Mill School District.
Who Collects the Impact Fees?
Impact fees are collected by different government entities.
York County collects the Fort Mill School District impact fee, even when the property is located inside Fort Mill or Tega Cay.
The Town of Fort Mill collects its own municipal impact fees on qualifying development within town limits.
These fees are generally paid during the building permit process and must be addressed before a qualifying new construction permit can be issued.
What Do Impact Fees Pay For?
The Fort Mill School District's $29,640 impact fee helps fund school facilities needed to accommodate additional students from new residential development.
The Town of Fort Mill's separate municipal impact fees help fund infrastructure and equipment related to:
Parks and recreational facilities
Fire protection facilities and equipment
Municipal facilities and equipment
These fees are intended to support capital improvements associated with growth rather than ordinary day-to-day government operating expenses.
Are There Exemptions to Impact Fees?
Certain projects may qualify for exemptions, waivers, or credits depending on the applicable ordinance.
For example, the Town of Fort Mill provides exemptions for certain renovations, residential additions, replacement structures that do not increase service units, and affordable housing that meets eligibility requirements.
However, exemptions under the town's municipal fee ordinance do not automatically exempt a property from York County's school impact fee.
Homeowners should verify eligibility with the appropriate jurisdiction before assuming an exemption applies.
Why Impact Fees Matter When Budgeting for a New Home
Impact fees can substantially affect the overall cost of new construction, particularly for smaller or more affordable homes.
For example, if you're planning to build a 1,000-square-foot home within Fort Mill's town limits, the combined $32,603 impact fee adds approximately $32.60 per square foot before accounting for land, construction, utility connections, and other permitting expenses.
Unlike many construction costs, impact fees generally do not decrease simply because you build a smaller home.
This makes it especially important to research these fees before purchasing property or finalizing a construction budget.
Final Thoughts
Building a home in Fort Mill can be a great investment, but understanding impact fees early in the process is essential.
Before purchasing land, confirm whether the property is inside town limits, which school district serves it, and what impact fees will apply.
At Burns Custom Homes, we believe homeowners should understand the full cost of building before construction begins. Proper planning and transparent budgeting can help prevent unexpected expenses and make the homebuilding process much smoother.
Impact fee amounts are based on published government schedules available as of October 2026 and are subject to change. Contact York County and the Town of Fort Mill for confirmation of fees applicable to your specific property.
