Maryland's New Data Center Regulations Signal Increased Scrutiny for Developers

Executive Summary

Maryland Governor Spanberger has proposed a slate of regulations placing new oversight requirements on data center development across the state, with localities simultaneously assessing what additional controls are available to them. Developers face a more complex approval environment, where longer timelines and layered compliance demands are the likely near-term reality. Local governments and regulatory bodies are the clear winners; data center developers absorbing land costs, interconnection deposits, and construction carrying costs are the clear losers. The InfraSale takeaway: Maryland-focused developers need to front-load regulatory engagement now, before project timelines are set by forces outside their control.

What Happened

Maryland Governor Abigail Spanberger has proposed a comprehensive set of regulations targeting new data center development in the state. The directives, put into motion in late September 2025, represent a formal shift in how Maryland intends to evaluate, approve, and oversee large-scale digital infrastructure projects going forward.

The governor's order introduces a layer of executive scrutiny that sits above existing local permitting processes. Localities are simultaneously exploring what tools are available to them under the new guidelines — suggesting a dual-track oversight structure that developers will need to satisfy at both the state and municipal levels.

The regulatory push reflects broader national concern about the pace of data center buildout and its downstream effects on utility infrastructure, land use, and community character. Maryland, home to a significant data center concentration in Prince George's County and the broader Northern Virginia spillover market, is among the first states to move from informal concern to formal executive action.

Why This Matters

This is not a zoning tweak. Executive-level regulation signals that data center development in Maryland has crossed a political threshold — it is now prominent enough to require gubernatorial attention, which means it will remain a live political issue for the duration of Spanberger's term.

Industry context: When a governor issues directives and localities simultaneously begin reviewing their own authority, the result is almost always a period of regulatory uncertainty lasting 12 to 24 months. During that window, developers who have not already secured entitlements are exposed to project delays that compress returns and erode site option values.

The dual-track structure — state oversight plus local authority review — creates a compounding compliance burden. A project that clears one level of review is not cleared at the other. Developers who treat Maryland as a straightforward permitting environment are likely to be caught flat-footed.

Longer term, these regulations could function as a de facto moratorium-light, slowing the pipeline without formally stopping it. That matters for investors underwriting projects on 18- to 36-month delivery schedules.

Power & Interconnection Impact

Assumption: Regulations of this type frequently include provisions tied to utility load review, requiring developers to demonstrate grid capacity and interconnection viability before local approvals can proceed. If Maryland follows that pattern, interconnection queue position becomes a permitting prerequisite, not just a project milestone.

Even without explicit power mandates in the governor's order, the indirect effect is significant. State-level scrutiny of data center development typically accelerates utility involvement in the approvals process. Pepco and BGE, the primary investor-owned utilities serving Maryland's data center corridors, may be asked to provide grid impact assessments as part of state review — adding months to pre-development timelines.

Developers who have not yet secured interconnection capacity or who are holding sites without confirmed substation access face heightened exposure. In a tightening regulatory environment, unentitled land with unclear power access is a liability, not an option.

Land, Zoning & Permitting Impact

The governor's order explicitly brings localities into the regulatory picture by prompting them to assess what authority they hold over new data center development. This is consequential. Local governments that previously lacked political cover to impose restrictions now have a state-level signal that scrutiny is acceptable — even encouraged.

Assumption: This dynamic typically produces a wave of local moratoria reviews, interim overlay zones, or conditional-use amendments targeting data centers specifically. Developers with active site control in Maryland counties should expect new conditions to attach to previously straightforward entitlement paths.

The permitting timeline for greenfield data center sites in Maryland should now be modeled conservatively. Developers accustomed to 9- to 12-month permitting windows in the region should stress-test their pro formas against 18- to 30-month scenarios. Sites with pre-existing entitlements or grandfathered approvals become materially more valuable in this environment.

Environmental review timelines may also extend. Data centers are large power consumers and significant contributors to impervious surface coverage — two categories that state environmental agencies routinely flag for additional review when given political direction to do so.

Investment Takeaway

Entitled sites gain a premium. Any Maryland data center site with existing zoning approval, conditional use permits, or prior environmental clearance is now priced in a different market than a raw greenfield parcel. Expect bid spreads to widen between the two categories.
Timeline risk is now underpriced. Pro formas that assume standard Maryland permitting windows need to be revised. Carry costs on a 12-month delay can erode IRR by 200 to 400 basis points on levered development deals.
Dual-track compliance adds cost. Engaging both state and local regulatory processes simultaneously requires legal, environmental, and community affairs resources that developers may not have budgeted. Factor this into deal underwriting.
Northern Virginia spillover demand does not disappear. The underlying demand signal driving Maryland data center interest — cloud, AI, federal contracts — remains intact. The regulatory environment slows supply, not demand, which could support lease rate stability for operational assets.
Watch for moratoria. Localities newly empowered to scrutinize data centers may move quickly. Developers should monitor county commission and planning board agendas in Prince George's, Montgomery, and Howard counties for interim zoning actions.

InfraSale Market Angle

For developers actively sourcing Maryland sites, the window between now and formal local regulatory action is the most important period for due diligence. Sites that appear viable today may carry new conditions within 90 days if localities move quickly on their own reviews. Developers should be engaging local planning departments now — not at permit application.

Landowners in Maryland's primary data center corridors should understand that their property's regulatory status has changed, even if the zoning code has not yet caught up. Sites positioned near utility infrastructure and with clean environmental histories have a differentiated story to tell in this environment.

For investors evaluating Maryland data center opportunities, the underwriting question has shifted from "can we build it?" to "how long will it take, and what will compliance cost?" Both questions require ground-level intelligence that standardized market reports cannot provide.

Infrastructure Theme: permitting
Who Benefits: Local governments and regulatory bodies gain more control.
Who's at Risk: Data center developers may face project delays and increased costs.
InfraSale Takeaway: Developers should proactively engage with local authorities to navigate new regulations.

Take Action

Maryland's regulatory environment is moving faster than most development timelines can absorb — developers who wait for clarity before acting will lose ground to those who engage early and position their sites accordingly. The difference between a project that closes in 2026 and one that stalls into 2028 may come down to whether the right site was identified and engaged before local moratoria took hold.

FAQ

What are the new regulations for data centers in Maryland?

Governor Spanberger has proposed a slate of directives placing new state-level oversight on data center development, with localities simultaneously reviewing their own available authority. The regulations introduce a dual-track scrutiny structure — state and local — that developers must satisfy before projects can advance. Specific rule text and compliance requirements are still being defined as the directives are put into motion.

How will these regulations affect my data center project?

Developers should expect longer approval timelines, additional compliance costs, and greater uncertainty around permitting outcomes in Maryland. Projects that have not yet secured entitlements are most exposed; sites with existing zoning approvals or conditional use permits carry significantly less timeline risk under the new environment.

What should I do to prepare for the new data center regulations?

Engage local planning departments and utility contacts immediately, before formal local rules are enacted. Commission a regulatory risk assessment for any active Maryland sites to identify exposure to new conditions or moratoria. Developers should also ensure their interconnection status is clearly documented, as state review processes may require grid impact confirmation as part of approvals.

Will the regulations stop data center development in Maryland entirely?

Assumption: The regulations are unlikely to halt development outright. They are more likely to function as a meaningful friction layer that slows new entrants and advantages developers with existing site control or established local relationships. Demand fundamentals driving Maryland data center interest — federal proximity, fiber density, cloud and AI growth — remain unchanged.

Which Maryland counties are most likely to see aggressive local action?

Industry context: Prince George's County, Montgomery County, and Howard County represent the highest-concentration data center corridors in Maryland. These are the markets where local scrutiny is most likely to translate quickly into interim zoning reviews or conditional-use amendments. Developers active in these markets should monitor planning board activity closely.
