Understanding Septic and Well Requirements When Building on Your Own Land in Chatham County, NC

Building a custom home on your own land in Chatham County, North Carolina offers incredible freedom and flexibility—but it also comes with important site development steps, especially if your land does not have access to public water or sewer. This means you’ll need to plan for a private septic system and well, which require proper permitting through the county.

At Travars Built Homes, we help guide you through this process—unlike some home builders who leave it up to the homeowner to figure it out alone.

Septic System Requirements in Chatham County

When public sewer isn’t available, an on-site septic system must be permitted and approved. In Chatham County, there are three primary permitting options:

1. Public Permitting Option

Through the Chatham County Environmental Health Division, this process involves submitting an application, fee, and site plan. A county inspector visits the site to determine soil and layout suitability. If the application is approved, an Improvement Permit (valid for five years) is issued. The applicant must obtain a Construction Authorization before beginning installation.

2. Private Permitting Option

You can also work with a licensed engineer or Authorized On-Site Wastewater Evaluator (AOWE) to design your system. This option can streamline timelines and provide design flexibility, while still meeting state regulations.

3. Hybrid Permitting Option

This approach combines public oversight with a private soil consultant and can offer a great fit for certain site conditions.
