What Buyers in Williamson County Need to Know About the Spring Hill Sewer Moratorium

Last Updated 2025-09-24

Spring Hill and Thompson’s Station are two of Williamson County’s fastest-growing communities, but if you’re shopping for a new build in 2025 or 2026, you’ll want to understand how the city’s recently imposed sewer moratorium could impact your plans. For buyers considering Franklin, Brentwood, or Nolensville, knowing what’s happening just down I-65 may be the market insight that tips your decision.

Why Is There a Sewer Moratorium in Spring Hill?

Rapid development in Spring Hill pushed local sewer infrastructure to its limit. In August 2025, the Tennessee Department of Environment and Conservation (TDEC) issued a consent order restricting new sewer connections unless the property or project already held specific vested rights. This move was designed to address capacity and regulatory issues, but it immediately affected builders, developers, and future homeowners.

Who Is Impacted?

Buyer Type	What Changes	What to Check
Custom Home Buyers	Available inventory of new builds in the area will be impacted.	Before you purchase a home, verify that the property and development your buying has vested sewer rights.
Buyers of spec homes	You may not be able to get sewer connection and not be able to move forward with your new build.	Before purchase, verify with the local authorities if building permits can be granted on your desired property.
Investors and Relocation Buyers	The moratorium will slow development of new builds in the Spring Hill and Thompson's Station area	Surrounding areas like Franklin or Brentwood may see a higher demand for new builds for buyers not willing to wait for the moratorium to end.

Current Status: What Projects Are Allowed?

The city has published and is regularly updating a list of developments and plat approvals with "vested rights"—these projects can proceed despite the moratorium. If you’re eyeing a specific neighborhood or builder, check if their lots are included:

• Spring Hill Vested Sewer Rights List (Official)

  Be cautious with new listings not on the list; building timelines could be pushed back until the city increases capacity or revises restrictions.

  
  

How Does This Affect Home Buying and Building?

1. Permit and Construction Delays

• Expect some new construction projects near 840/31 to face lengthy delays if not already vested.

• City officials indicated possible moratorium solutions mid-to-late 2026, but there’s no guarantee.

2. Competitive Bidding for Vested Lots

• Fewer buildable lots means more competition and, potentially, higher prices or bidding wars in the most desirable neighborhoods.

3. Resale Market Ripple Effects

• Limited new construction inventory could make existing homes in Franklin, Brentwood, and other Williamson County markets even more attractive for buyers who need to move without delay.
