What South Carolina’s 2025-2026 Legislative Session, the Spartanburg County Data Center Litigation and the Silfab Controversy Signal for Real Estate Attorneys

Standard

South Carolina’s 2025-2026 legislative session demonstrated that land use and zoning issues are becoming increasingly prominent in economic development, environmental regulation, and local governance. While relatively few zoning-related bills were enacted, several significant proposals and the ongoing Data Center litigation in Spartanburg County and the Silfab Solar controversy in York County reveal growing tension between economic growth initiatives and community oversight. For South Carolina real estate attorneys, these developments may foreshadow a more active and contentious zoning landscape in the years ahead.

Legislative Efforts to Expand Zoning Oversight

One of the most notable zoning bills introduced during the session was Senate Bill 530. The bill proposed adding Section 6-29-815 to the South Carolina Code and would have required development activity to cease immediately whenever a zoning authority determined that a property’s current or proposed use was not permitted under the applicable zoning classification. The legislation would have invalidated previously issued permits and suspended construction during administrative and judicial appeals unless a court ordered otherwise. Although the bill did not become law, it reflected increasing legislative concern regarding projects that proceed while zoning disputes remain unresolved.

For attorneys representing developers, lenders, and title insurers, S.530 is noteworthy because it would have significantly altered reliance interests associated with permits and approvals. The proposal suggests that lawmakers are closely watching disputes involving local zoning interpretations and vested rights.

The Rise of Data Center Regulation

A major emerging issue during the session was the regulation of data centers. South Carolina continues to attract technology and infrastructure investment, but lawmakers have begun grappling with the substantial impacts data centers can have on utilities, water resources, transportation infrastructure, and surrounding land uses.

Two significant bills were introduced:

  • S.867, the Data Center Development Act, would establish a state permitting framework administered through the Department of Environmental Services and require siting permits, infrastructure adequacy assessments, environmental impact reviews, water-efficiency standards, operational reporting, and coordination with local land-use planning.
  • S.902, the Data Center Siting Act, proposed a similar approach but would place substantial authority with the Public Service Commission, requiring certification before a data center could begin operations and establishing standards addressing infrastructure, environmental impacts, utility costs, buffers, and local planning considerations.

Neither bill became law during the session. However, both are significant because they recognize that traditional local zoning tools may be insufficient to address the statewide implications of large-scale data center development. The introduction of multiple bills targeting the same issue suggests a growing consensus that additional regulatory oversight is likely forthcoming.

For practitioners, future data center projects may require navigating both traditional zoning approvals and additional state-level review processes. Attorneys should anticipate increased scrutiny of utility capacity, water consumption, environmental impacts, and compatibility with surrounding land uses.

The Spartanburg County Data Center Litigation

Another development worth watching is the ongoing litigation involving the proposed Valara Holdings/NorthMark data center project in Spartanburg County. The dispute highlights many of the same issues that lawmakers attempted to address through the proposed data center legislation.

The approximately $3 billion project includes a large-scale data center campus and a proposed 450-megawatt natural gas-fired power generation facility intended to serve the development. Local residents and advocacy groups have challenged both the permitting process and the scope of regulatory review applied to the project.

One lawsuit, filed by the Southern Environmental Law Center on behalf of Concerned Citizens of Spartanburg County, alleges that the project was processed through permits typically used for minor land development rather than being subjected to the county’s major land development review procedures. Opponents contend that classifying the project in this manner limited opportunities for public participation and avoided the level of review ordinarily required for developments of comparable scale.

A separate proceeding before the South Carolina Public Service Commission has raised another significant question: whether the project’s proposed 450-megawatt power plant qualifies as a “major utility facility” subject to review under South Carolina’s Utility Facility Siting and Environmental Protection Act. Project opponents argue that the plain language of the statute requires PSC approval before construction can proceed, while the developer maintains that the generation facility is intended solely for private, on-site use and therefore falls outside the Act’s jurisdiction.

The litigation is particularly important because it reflects growing public concern regarding data centers’ impacts on electricity demand, water usage, noise, environmental resources, and local infrastructure. It also demonstrates that even where local zoning approvals have been obtained, affected citizens are increasingly willing to pursue administrative and judicial challenges when they believe regulatory oversight has been insufficient.

For real estate practitioners, the Spartanburg matter provides a practical example of why future data center developments may require more than conventional zoning and land-use analysis. Questions involving utility regulation, environmental permitting, public participation requirements, and state-level siting authority are increasingly becoming intertwined with local development approvals. Notably, many of the issues now being litigated mirror the concerns addressed in proposed legislation such as the Data Center Development Act (S.867) and the Data Center Siting Act (S.902), suggesting that future legislative efforts may be influenced by the outcome of these disputes.

The Silfab Solar Controversy: A Real-Time Zoning Lesson

My colleague, Vance Brabham provided a detailed description of the Silfab Solar chemical spill and zoning implications in a blog article in May, 2026.  No recent South Carolina development has highlighted zoning challenges more vividly than the ongoing controversy surrounding the Silfab Solar facility in York County.

The dispute originated with York County’s determination that solar manufacturing was permitted within the facility’s light industrial zoning classification. A subsequent York County Board of Zoning Appeals decision concluded that solar panel manufacturing should instead be treated as a heavy industrial use. Litigation followed concerning the applicability of that determination to Silfab’s project.

The matter intensified in March 2026 when the facility experienced two separate chemical incidents, including releases involving potassium hydroxide and hydrofluoric acid. Following the incidents, the South Carolina Department of Environmental Services ordered the facility to cease operations pending further investigation of safety and chemical-handling protocols.

The response from state and local officials was particularly notable from a zoning perspective. Attorney General Alan Wilson publicly questioned the zoning and permitting process that allowed the facility to be located near Flint Hill Elementary and Middle Schools and demanded information from York County regarding the approvals issued to Silfab. The Attorney General also called for transparency regarding the project’s siting and safety reviews.

York County officials responded by defending the Planning Department’s actions, stating that all zoning approvals and permits were issued in accordance with applicable ordinances and that county staff had provided a zoning verification letter concluding that the use was permissible at the site. County officials further asserted that the county had followed established procedures throughout the approval process.

The Silfab matter demonstrates how zoning decisions can evolve from local administrative determinations into matters of statewide political and public concern, particularly when environmental and public safety issues arise.

What Does This Foreshadow for South Carolina Zoning?

Several themes emerge from the 2025-2026 session and the Silfab controversy.

First, state officials appear increasingly willing to scrutinize local zoning decisions when projects have significant environmental, infrastructure, or public safety implications.

Second, large-scale industrial and technology projects are likely to generate pressure for additional state-level permitting and siting requirements. The data center bills demonstrate that legislators are considering regulatory models that supplement local zoning rather than relying on it alone.

Third, the emphasis on permit validity, vested rights, and enforcement reflected in S.530 suggests that future legislation may seek to limit the ability of disputed projects to continue operating while zoning challenges remain pending.

Finally, the political attention surrounding Silfab indicates that land-use decisions involving schools, residential communities, environmental concerns, and industrial development will likely face heightened public scrutiny moving forward.

Although the 2025-2026 session did not produce sweeping zoning reform, it revealed an unmistakable trend: South Carolina is entering a period of increased attention to land-use regulation. The debates surrounding Silfab Solar in York County, the proposed data center legislation, and the ongoing Spartanburg County data center litigation all point toward greater scrutiny of large-scale projects whose impacts extend beyond traditional zoning considerations. Legislators, regulators, local governments, and courts are increasingly being asked to balance economic development with environmental protection, infrastructure capacity, public participation, and community compatibility. For South Carolina real estate attorneys, these developments suggest that future zoning disputes will involve not only local land-use ordinances but also broader questions of state oversight, permitting authority, and public accountability.

Data Centers Raise Legal Questions for Rural South Carolina

Standard

Across rural South Carolina, data center proposals are generating increasing controversy as residents challenge whether counties are complying with zoning statutes, comprehensive plans, and public‑notice requirements.

In Colleton County, Council amended its zoning ordinance to add data centers as a permitted use and to create a special exception within residential districts – changes that paved the way for a proposed $6 billion facility near the environmentally protected ACE Basin. In January, neighboring landowners, represented by the Southern Environmental Law Center, filed suit alleging that the county enacted these amendments without adequate notice or transparency, that the changes conflict with the county’s comprehensive plan, and that allowing an industrial special exception within a rural district is inconsistent with existing zoning classifications.

Similar disputes continue to surface statewide. In Marion County, Council recently approved a $2.4 billion data center project and a fee‑in‑lieu‑of‑tax agreement. The project appeared on the agenda only under the code name “Project Liberty” and was covered by a nondisclosure agreement, leaving the public without meaningful information until the final reading. Aiken and Berkeley Counties have faced comparable challenges.

Opponents of data centers emphasize their extraordinary electrical demand, which has already strained power grids across the country. Some estimates now place data‑center consumption at roughly seven percent of U.S. electricity use, with projections continuing to rise. In the Colleton debate, residents expressed concern that utilities lack sufficient capacity to serve the proposed facility and that ratepayers – particularly Santee Cooper customers – may ultimately bear the cost of necessary upgrades.

Water usage presents a parallel problem. Data centers generate substantial heat and rely heavily on water‑based cooling. The volume required can impose real stress on local water systems, particularly in rural areas. While newer closed‑loop cooling technologies reduce consumption, they require additional energy and higher capital investment.

Other community impacts have also drawn scrutiny. Backup diesel generators – which data centers depend on for uninterrupted service – emit gases and particulates that may pose health risks. Residents in rural counties also cite noise, light pollution, and the visual intrusion of large industrial campuses as threats to the historic and environmental character of their communities.

Yet despite these concerns, the economic incentives remain significant. Proponents of the Marion County project note that the facility could generate nearly $28 million annually for a county operating on a $25 million budget. Construction phases typically span several years, providing a substantial economic boost. And although data centers require relatively few employees once operational, they nevertheless contribute positively to local employment and tax revenue. Moreover, the facilities are essential to the growth of artificial intelligence and advanced computing – technologies many policymakers liken to a modern “space race.”

The General Assembly has taken notice. Several bills addressing data‑center siting, utility impacts, and environmental standards have been introduced this session. Developments in the Colleton County litigation, along with potential legislative action, will likely shape future permitting and zoning practices statewide.

For South Carolina lawyers, these projects are becoming increasingly complicated to navigate to completion. Title insurers are increasingly view data centers as high‑risk properties due to their scale, public visibility, and susceptibility to challenge. Attorneys may be asked to perform extended title examinations, provide more detailed zoning analyses, and secure specialized endorsements requiring careful underwriting. As counties pursue these high‑value developments and as communities continue to push back, lawyers will as always be on the front lines.
