Introduction

Fort Mill and Lake Wylie are two of the most sought-after areas in York County, South Carolina — known for top-rated schools, access to Charlotte, and a high quality of life. Many buyers looking here aren’t just searching for an existing home; they want to build a custom home that fits their vision and lifestyle.

So how much does it really cost to build a custom home in Fort Mill or Lake Wylie in 2025? Let’s break it down.

1. Land Costs

The first step in any custom build is purchasing a lot. In Fort Mill, developed residential lots typically range from $150,000 to $350,000, depending on location, size, and amenities. In Lake Wylie, waterfront or water-view lots command a premium, often between $300,000 and $800,000 or more.

Buyers should also factor in costs for site prep — clearing trees, grading, or adding utilities — which can add anywhere from $10,000 to $50,000 depending on the property.

These figures include materials, labor, and builder fees, but they can vary depending on customization, finishes, and builder selection.

3. Design and Planning Fees

Custom home construction involves architectural design, engineering, and permitting. Buyers should budget 5–10% of the total build cost for design and professional fees. This step ensures your plans meet both your vision and local building codes.

4. Utilities and Infrastructure

Not every lot comes ready to build. Depending on the location, you may need to add septic, well, or water connections.

  Public water and sewer: Common in Fort Mill neighborhoods, included in many newer subdivisions.

  Private septic or well: More common around Lake Wylie and rural parts of York County.

  
  

Utility setup costs can range from $5,000 to $25,000 depending on site requirements.

York County and the towns of Fort Mill and Clover each have their own permitting and inspection processes. Builders usually handle this, but buyers should understand it’s part of the overall cost and timeline.

Permitting fees typically fall between $2,000 and $10,000, depending on project scope.

6. Timeline and Cost Variables

From design to move-in, expect the full process to take 12 to 18 months. Material prices, labor availability, and weather can all impact final costs. Choosing a reputable local builder with Fort Mill or Lake Wylie experience can help control both the budget and the timeline.
