New Model Law Empowers Cities to Regulate Rapidly Expanding Data Centers

Executive Summary

A proposed model law is giving local governments a formal framework to push back against data center expansion that has outpaced the codes most municipalities have on the books. The gap between how fast data centers are being built and how well local governments can manage that growth is now being treated as a structural problem, not a one-off zoning dispute. Local communities and their elected officials stand to gain meaningful leverage; developers, by contrast, face the prospect of a more fragmented and time-consuming permitting environment. The InfraSale takeaway: site selection strategy must now include a granular read of local regulatory posture, not just transmission access and power availability.

What Happened

Climate Mayors' executive director stated plainly that data centers "are moving faster and at a larger scale than most local codes were built to handle." That observation sits at the center of a push to introduce a model law designed to give cities more direct authority over where, how, and under what conditions data centers can be built and operated.

The model law framework is being positioned as a tool for municipalities that currently lack the statutory standing to impose meaningful conditions on large-scale data center projects. Without it, many cities find themselves legally constrained to rubber-stamp projects that arrive with state-level approvals already in hand.

The Climate Mayors network — a coalition of U.S. city leaders organized around climate and sustainability goals — is lending institutional weight to the effort. That backing signals this is not a fringe position; it reflects a growing consensus among local officials that the current regulatory architecture was designed for a different era of infrastructure development.

The core tension is straightforward: data center development timelines are measured in months, while municipal code updates are measured in years. The model law attempts to close that gap before the next wave of capacity expansion — driven in large part by AI workload demand — makes the problem worse.

Why This Matters

This is not an isolated piece of advocacy. It is a signal that local regulatory risk is becoming a structural feature of the data center site selection process, not an edge case. Developers who have grown accustomed to treating local government as a permitting formality are going to encounter a different reality in markets where this model law — or its derivatives — takes hold.

Model laws work by providing a replicable template that individual jurisdictions can adopt, adapt, and codify into local ordinance. The adoption curve can be uneven, but once a model gains traction in even a handful of high-profile markets, it creates a demonstration effect. Other cities follow. That is how local regulatory environments shift at scale.

Industry context: The pattern here mirrors what happened with short-term rental regulations and cannabis licensing — model frameworks that started in a handful of progressive municipalities and spread across jurisdictions within three to five years. Data center developers should treat that precedent seriously.

The broader implication is market bifurcation. Some jurisdictions will adopt aggressive versions of this framework; others will use it as a floor and add their own conditions. A smaller number will reject it outright in an effort to attract investment. Developers will need to price that variance into every site decision they make going forward.

Power & Interconnection Impact

Increased local regulatory authority almost certainly extends to energy use. Municipalities that gain the power to condition data center approvals may attach requirements around energy sourcing, power purchase agreements, on-site generation, or carbon commitments. That adds complexity to procurement and can affect how projects are structured for utility interconnection.

Assumption: Where local governments gain oversight of energy consumption thresholds, some will attempt to impose renewable procurement mandates or cap total load draw from local distribution infrastructure — particularly in markets already experiencing grid stress. That could translate into longer pre-development timelines as developers negotiate conditions alongside standard interconnection filings.

The interconnection queue pressure data centers are already navigating at the ISO level may compound if local approvals become a new gating item. A project that clears MISO or PJM queue milestones but then hits a local regulatory hold loses time it cannot recover cheaply.

Land, Zoning & Permitting Impact

This is where developers will feel the most immediate operational friction. Zoning codes in most U.S. municipalities were not written with hyperscale data centers in mind. Industrial classifications that work for a 50,000-square-foot light manufacturing facility do not translate cleanly to a 500MW campus with cooling infrastructure, generator farms, and 24-hour truck traffic.

A model law that empowers cities to create data center-specific zoning categories is a double-edged instrument. On one hand, it could clarify the approval pathway in jurisdictions that currently have no defined use category for the asset type. On the other hand, it creates a new layer of local discretion that developers must anticipate and navigate.

Permitting timelines are the first casualty of regulatory ambiguity. If local governments are given new authority without clear administrative guidelines, the practical effect is longer entitlement cycles. Developers sourcing sites in markets where this framework is being considered should build additional permitting buffer into their underwriting — six to twelve months of additional lead time is a reasonable working assumption until market precedents are established.

Community opposition is also a factor. The model law framework gives organized local opposition groups a formal venue — public hearings, comment periods, conditional approval processes — that may not have existed before. That changes the stakeholder management calculus significantly.

Investment Takeaway

Regulatory due diligence becomes a first-order site selection criterion. Understanding whether a target jurisdiction is considering or has adopted model law provisions is as important as substation proximity and fiber availability.
Markets with stable, permissive local governments gain near-term premium. Data center developers and their capital partners will bid up sites in jurisdictions with predictable approval pathways, compressing cap rates in those markets.
Entitlement risk gets repriced. Projects in markets where this framework is active or likely will carry higher development risk premiums. Investors underwriting speculative development should model permitting delays explicitly.
Jurisdictional diversification matters more. Portfolios concentrated in a handful of markets face correlated regulatory risk if the model law spreads quickly. Geographic spread across jurisdictions with varying regulatory postures reduces that exposure.
Operational data centers with existing entitlements gain defensible value. Permitted, operating assets become scarcer relative to what can be newly approved — a dynamic that supports asset valuations for existing inventory.

InfraSale Market Angle

Developers actively sourcing data center sites need to treat local regulatory posture as a first-pass filter, not a downstream legal review item. The model law framework means that community relations, zoning classification, and local political dynamics are now underwriting variables. Sites that look attractive on power and land metrics alone may carry hidden entitlement risk that doesn't surface until a project is already in the queue.

For landowners in markets where data center demand is high, the emerging regulatory environment creates both opportunity and complication. Parcels that are pre-zoned or conditionally approved for data center use — or that sit in jurisdictions with demonstrated regulatory clarity — are worth more than raw land with equivalent power access but no entitlement visibility.

Local governments and utilities reading this closely should understand that the model law also gives them market power they haven't traditionally held. Jurisdictions that develop clear, transparent, and efficient approval frameworks for data centers — rather than opaque or adversarial ones — will attract capital and build negotiating leverage over project conditions simultaneously.

Take Action

The regulatory environment for data center development is shifting at the local level, and site selection strategies that don't account for municipal posture will produce costly surprises. Mapping permitting risk before committing capital to a site is now a baseline requirement, not a best practice.

FAQ

What are the implications of the new model law for data center developers?

The model law creates a formal basis for local governments to impose conditions on data center approvals that previously had to be negotiated informally or not at all. Permitting processes in adopting jurisdictions will likely become more structured, more public, and potentially longer. Developers should audit their pipeline for sites in markets where this framework is gaining traction and adjust entitlement timelines accordingly.

How can local governments effectively regulate data center growth without deterring investment?

The most effective approach is regulatory clarity rather than outright restriction. Jurisdictions that create defined use categories, transparent approval criteria, and predictable timelines will attract developers who value certainty — while still retaining the authority to attach meaningful conditions around energy use, noise, water consumption, and community benefits.

What should investors consider in light of changing data center regulations?

Local regulatory risk is now a material variable in data center underwriting. Investors should require permitting risk assessments as part of standard due diligence, weight jurisdiction-level regulatory stability in site scoring models, and account for potential timeline extensions in project-level IRR models. Assets with existing entitlements in regulated markets may command a premium as new approvals become harder to obtain.

Is this model law legally binding on cities?

Model laws function as templates, not mandates. Individual municipalities must formally adopt them through their standard legislative processes for the provisions to carry legal weight. Adoption rates and the degree of modification will vary significantly by state and city — which is precisely why tracking jurisdiction-by-jurisdiction regulatory developments is essential for site selection teams.

How does this trend relate to broader data center backlash?

Opposition to data center siting has been building in communities across Virginia, Texas, Georgia, and other high-density markets. The model law is a formal institutional response to that backlash — an attempt to give local governments a structured mechanism for managing growth rather than simply blocking individual projects. That distinction matters: regulated development with community conditions is a very different outcome than outright moratoria.
