Can Zoning Stop Your Ground-Mount Solar Project? What Businesses and Farms Should Know

You've found the perfect spot for a ground-mount solar array. Maybe it's a back field on your farm or an open lot behind your facility. The savings look great. Then a new question comes up: will your township actually let you build it?

The short answer is that it depends on how your local zoning ordinance treats solar. Some projects get approved with a simple application in two to three weeks. Others go through public hearings, need a lawyer, and take 6 to 12 months. A few can't move forward at all.

The good news is that you can find out which path you're on before you sign a contract. Below, we'll walk you through why zoning for solar is getting harder, the four ways a township can approve a project, the costs to plan for, and how Paradise Energy checks your site's zoning requirements before you sign a contract with us.

One quick note: most of what follows applies to ground-mount systems. Rooftop solar usually faces far fewer zoning hurdles. If you're still deciding between the two, see our ground mount vs. roof mount comparison.

Why Is Zoning for Solar Getting Harder?

In short, data centers. Data center development has exploded across the country. Many local governments have responded by tightening their zoning ordinances to control large commercial land uses.

The challenge is that solar often gets lumped in with those projects. A 250 kW array on a farm is very different from a massive data center campus. But under some new ordinances, both are treated as major commercial developments.

Here's what that looks like in practice:

• Rules are changing fast. Townships nationwide have been updating or creating new ordinances since 2024. In many cases, projects already in progress weren't grandfathered in under the old rules.
• Small systems are getting swept up. Some new ordinances treat systems as small as 10 kW, even residential ones, the same way they treat large power generators.
• The stakes are higher. When zoning problems surface after a contract is signed, they can mean surprise costs, long delays, or a project that can't be built.

This is also why a neighbor's easy install a few years ago doesn't guarantee yours will go the same way.

First, What Is Zoning?

Zoning is a set of local government rules that divides a town or township into sections. It controls how land and buildings can be used in each section. (In Maryland, zoning is typically handled at the county level, but it works much the same way.)

When a township reviews a solar project, one of the first things it looks at is how the system will be used. Nearly every solar project falls into one of two buckets:

Most businesses and farms install solar to offset their own electricity use, so their projects are typically accessory uses. The problem is that some newer ordinances classify even small systems as principal uses. When that happens, part of our job is working with the township to apply its rules in a way that fits the actual project.

The Four Ways a Township Can Approve a Solar Project

Every zoning ordinance spells out which approval path a project must follow. Four main pathways exist, and each carries more risk and complexity than the last.

1. Permitted by Right

This is the simplest path and what most people picture when they think of "zoning." Solar is allowed in your zoning district, so you don't need special approval.

• Review is administrative, handled by township staff
• You typically just submit project plans and pay an application fee
• Approval usually takes about two to three weeks

2. Special Exception

You may also hear this called a "special use" or "special use permit." The ordinance allows solar in your district, but only if the project meets extra solar-specific requirements.

• The project must meet both the zoning district's rules and the ordinance's solar rules, often no matter the system size
• The township may add other reasonable conditions, such as a glare or noise study
• The application is publicly advertised and heard by the zoning hearing board
• Neighbors can object, and an approval can be overturned if they show real public safety concerns

3. Conditional Use

A conditional use is similar to a special exception. The difference is that requirements are tailored to your specific project, and elected officials make the final call.

• The planning commission reviews the project and makes a recommendation
• The application is publicly advertised and heard
• Because elected officials decide, the outcome can be influenced by local politics

4. Variance

A variance is the most difficult path. It's needed when the ordinance does not allow the project as proposed. You're asking for formal legal relief from the rules.

• You must prove that the ordinance creates an unnecessary hardship
• The hardship has to come from something unique about the land or the zoning district, not the project itself
• Financial goals, like wanting a better return on investment, don't count as hardship
• An approved variance sets a new legal precedent for the zoning district, or even the entire ordinance

There are two kinds. An area variance asks for relief from specific ordinance requirements. A use variance asks to allow something the ordinance bans outright, such as a township that prohibits systems larger than 10 kW. Use variances are the hardest of all to win.

Why Do Timelines and Fees Vary So Much From Township to Township?

Even two projects on the same pathway can have very different experiences. Much of it comes down to the calendar and how familiar a township is with solar.

Boards usually meet once a month. If a question comes up at a meeting, the answer often has to wait until the next one. A few small issues can push a project back by several months. In tougher cases, zoning and permitting alone can stretch to 6, 9, or even 12 months.

Here are some of the most common reasons a project slows down:

Confusion About the Approval Pathway

• Ordinances can have unclear or conflicting definitions for solar
• A project may be placed on the wrong pathway or given the wrong label, such as a solar generator being classified as community solar
• The word "variance" gets used loosely, even for projects that are really special exceptions
• When the rules are unclear, a project can end up defaulting to the variance process, which is the hardest path

Requirements That Go Beyond the Ordinance

• A township may ask for studies or conditions its own ordinance doesn't require, such as a glare study on a permitted-by-right project
• Applicants may be asked to prove hardship even when they aren't requesting a variance
• Public opposition can come up even when there are no valid safety concerns

Process and Paperwork

• Input from fire, police, or emergency services may be treated as a final decision instead of advice
• Advisory county or state bodies may be treated as the decision-maker
• Some townships require every other permit to be finished before zoning review can begin

Third-Party Reviewers

Townships that don't see many solar projects often hire outside engineering firms or code agencies to review them. This can be one of the biggest sources of surprise costs and delays.

• Review fees can reach tens of thousands of dollars and may not be known upfront
• Plans may go through several rounds of detailed revisions
• Each round can add weeks or months

None of this means your project will run into trouble. It means it's worth knowing the rules going in. When questions like these come up, our team works with the township to ensure its ordinances and procedures are followed correctly.

What Zoning-Related Costs Should You Plan For?

The cost of the solar equipment and installation is only part of the picture. Depending on your township, you may also see some of the costs below.

To make this concrete, here's a real example of the permitting overview our team prepared for a 250 kW ground-mount project in New York:

Decommissioning bond. This is a financial guarantee that the system will be removed properly at the end of its life. When required, it can be one of the highest zoning-related costs.

Financial security. Some townships require a separate financial guarantee for approval.

Third-party review fees. As mentioned above, outside reviewers can add fees that reach tens of thousands of dollars.

Studies and reports. A township may request additional studies, such as glare or noise studies, especially for special exceptions and conditional uses.

Legal counsel. Special exceptions, conditional uses, and variances often call for an attorney.

Site and environmental factors. We also look at streams, wetlands, enhanced setbacks, and floodplains. Building a ground mount in a floodplain is possible, but it usually means paying significant fees to the state based on the project's size and how much of it sits in the floodplain.

A Potential Way to Save

Some permits depend on how much land your project disturbs. In the example above, you could avoid stormwater and related permits by keeping site disturbance under one acre. Knowing this early gives you options, like adjusting the system's size or layout. That is why Paradise Energy digs into these requirements at the start of a project to keep costs down and avoid unexpected expenses during development.

Do You Need a Lawyer for Solar Zoning Approval?

Not always. Many projects move forward without one.  In many cases, short-term legal fees are more cost-effective than fighting long-term procedural battles without counsel.

Either way, our team handles the zoning and permitting work behind the scenes, and we only recommend counsel if we know it's the best investment for your project.

How Paradise Energy Checks Your Zoning Before You Sign

We don't want you to learn about a zoning problem after you've signed a contract. So for qualified ground-mount projects, we do the research up front, while we're putting together your quote.

Here's how it works:

1. We gather the rules. Our operations team pulls every ordinance and regulation that applies to your site. That includes township or county, state, and other agencies.
2. We sort out what's required. Each permit or approval is marked as something we handle in-house, something that needs a third party (like civil engineering), or something that isn't required.
3. We estimate the costs. Those findings are priced based on your system size and built into your proposal.
4. We flag big concerns right away. If we find something that could add major cost or block your project, your solar consultant will talk with you about it directly.

We also review civil and environmental factors, like nearby streams, wetlands, and floodplains, during this same step. Once you move forward, we handle the permit paperwork itself as part of our six-step solar installation process.

Why This Matters for You

• Fewer surprises. You see likely zoning costs in your proposal instead of as a change order later.
• A clear picture of risk. You'll know which approval pathway your project likely faces and what could affect your timeline.
• More options. Knowing the rules early can help you adjust your system's size or location to reach an easier path.
• Better leverage. Understanding the ordinance puts you in a stronger position when working with the township.

Keep in mind that these are estimates. Actual costs may be higher or lower once the township reviews your project. But an informed estimate is far better than a surprise.

Be Cautious of a Quote That Sounds Too Easy

When you’re comparing proposals, a low price and a promise of “no zoning concerns” can be tempting. Sometimes a project really is that simple. But zoning is often where the toughest problems show up.

We’ve had business owners come to us after signing with another installer who told them their project would be straightforward, low cost, and quick. Then the project stalled in zoning or ran into costs nobody had planned for. By that point, they had already lost time, and sometimes money, and they needed help figuring out what to do next.

Before you choose an installer, ask a few questions:

• Have you reviewed the zoning ordinance for my property?
• Which approval pathway do you expect my project to follow?
• Are zoning-related costs, like bonds, studies, or third-party review fees, included in this quote?
• What happens if the township requires something that isn’t in the quote?

A careful answer to these questions is worth more than a confident promise. A lower bid that leaves out zoning costs may not end up being the lower-cost option.

Know Your Zoning Path Before You Commit

Zoning can feel like the most unpredictable part of going solar. It doesn't have to be. When you know your approval pathway, likely costs, and possible roadblocks up front, you can make a confident decision about your project.
