PRAR Government Affairs & Industry News

FORT MILL, SC — The ongoing legal and regulatory developments surrounding the Silfab Solar manufacturing facility in York County continue to draw significant attention from residents, local government officials, and the real estate community.

Recent developments include Silfab’s notification of plans to restart commissioning activities, additional legal action involving the Fort Mill School District, and unresolved questions about the facility’s zoning classification and existing development approvals.

Piedmont Regional Association of REALTORS® (PRAR) is monitoring these developments to help members stay informed about issues that may affect property ownership, land use, development, and real estate transactions throughout our region.

Latest Development: Silfab Moves Toward Restarting Commissioning Activities

On November 6, 2026, Silfab Solar notified the South Carolina Department of Environmental Services (SCDES) of its intention to restart commissioning activities at its Fort Mill facility following the required 72-hour notification period.

The announcement follows a March 2026 compliance agreement established after two chemical-related incidents at the facility.

According to SCDES, Silfab has satisfied conditions 1–6 of the agreement and must continue complying with condition 7, which includes ongoing reporting requirements. The company is also implementing recommendations from an independent engineering evaluation.

SCDES has indicated that agency personnel will be stationed at the facility during commissioning activities to provide additional regulatory oversight.

Importantly, restarting commissioning does not necessarily mean full manufacturing operations involving regulated chemicals will immediately begin. Additional steps remain necessary before those manufacturing processes commence.

York County acknowledged Silfab’s notification on November 6 and stated that it will continue monitoring the facility’s activities.

Zoning Dispute Remains Unresolved

A central issue in the Silfab case is whether solar panel manufacturing is permitted under the property’s existing Light Industrial zoning classification.

In May 2024, the York County Board of Zoning Appeals determined that solar panel manufacturing was not a permitted use within that zoning district.

On July 21, 2026, Circuit Court Judge William McKinnon upheld the Board of Zoning Appeals’ interpretation.

However, the ruling did not specifically determine whether the decision invalidates permits or approvals previously issued to Silfab.

The zoning decision is under appeal, and its application to Silfab’s existing operations remains unresolved.

In October 2026, both York County and Silfab filed separate declaratory judgment actions seeking clarification of the company’s legal right to operate under its existing approvals.

These proceedings are intended to resolve an important question: Does the zoning interpretation apply to Silfab’s previously approved facility, or only to future development and land-use decisions?

Until the courts provide further clarification, uncertainty remains regarding the legal status of the facility’s manufacturing operations.

The Fort Mill School District has also taken legal action related to the ongoing dispute.

In late October, the district moved to intervene in the litigation involving Silfab and York County. In early November, additional legal filings raised concerns regarding the health and safety of students and staff at nearby schools.

The district’s involvement reflects ongoing community concerns about the facility’s proximity to educational facilities and residential neighborhoods.

The legal proceedings have not established that the facility poses an ongoing health threat. Environmental compliance and public safety questions remain subject to review by the appropriate regulatory authorities.

What REALTORS® Need to Know

While PRAR does not take a position on the pending litigation, the case raises several important considerations for real estate professionals.

1. Property Values and Market Conditions

Industrial development, land-use disputes, and environmental concerns can influence buyer perceptions and real estate decisions.

However, there is currently insufficient verified market data to conclude that the Silfab facility has caused a measurable change in surrounding property values.

REALTORS® should avoid making unsupported statements about potential increases or decreases in property values and rely on appropriate market data when discussing property valuation.

2. Buyer Questions and Property Disclosures

REALTORS® working with buyers and sellers in the surrounding area may encounter questions regarding the facility, zoning disputes, environmental compliance, and future operations.

Members should provide accurate, factual information from reliable sources and avoid speculation regarding legal outcomes, environmental risks, or future property values.

When questions involve specific disclosure obligations, environmental conditions, or potential legal liability, members should consult their broker-in-charge and appropriate legal professionals.

3. Zoning and Land-Use Decisions

The outcome of the pending litigation may provide important clarification regarding the relationship between zoning interpretations, previously issued development approvals, and the rights of property owners and developers.

These questions are relevant to real estate professionals because zoning classifications and permitted uses can directly affect development opportunities, investment decisions, and property transactions.

4. Environmental Oversight and Public Information

SCDES is responsible for enforcing applicable state environmental requirements, while York County administers local zoning and land-use regulations.

Members should understand that environmental permits and local zoning approvals are separate regulatory matters.

Compliance with one does not automatically resolve legal questions involving the other.

What Happens Next?

Several important developments remain pending:

  • Commissioning activities: Continued updates from SCDES regarding Silfab’s restart process and compliance requirements.
  • Zoning appeal: Further proceedings involving the July 2026 Circuit Court ruling.
  • Declaratory judgment litigation: Court clarification regarding Silfab’s existing permits, approvals, and ability to operate under the current zoning classification.
  • School district involvement: Additional proceedings addressing the district’s legal claims and concerns.
  • County and state oversight: Continued monitoring of the facility’s operations and compliance with applicable regulations.

As of November 10, 2026, the broader legal dispute remains unresolved.
