Pennsylvania Zoning Laws – What Property Owners and Developers Need to Know

Zoning laws play a critical role in shaping how land is used and developed throughout Pennsylvania. Whether you are a homeowner planning an addition, a business owner expanding operations, or a developer pursuing a new project, understanding local zoning requirements is essential to avoiding costly delays and legal complications. Zoning regulations vary by municipality, and are strictly enforced. As such, early identification of potential zoning issues, as well as experienced legal guidance, can make the difference between a successful project and one that stalls before it begins.


In Pennsylvania, zoning authority is primarily governed by the Pennsylvania Municipalities Planning Code (MPC). Municipalities adopt zoning ordinances in accordance with the Pennsylvania Municipalities Planning Code (MPC). These ordinances regulate land use within the township, borough or city, and control permitted uses, building height, lot size, setbacks, density, parking requirements, and other development standards.

Each municipality adopts its own zoning map and ordinance, meaning the rules applicable to one property may differ significantly from those governing a neighboring community. Compliance with the local zoning ordinance is required before most land development, construction, or changes in property use can proceed.

A critical first step in any land development or improvement project is identifying potential zoning issues. Common zoning concerns include whether the proposed use is permitted in the zoning district; whether there are any existing nonconforming uses or structures on the property; the setback, height, or lot coverage restrictions; any parking, access, or buffering requirements; and environmental or overlay district limitations.

Failure to identify these issues early can result in permit denials, enforcement actions, or the need to redesign a project after significant time and expense have already been invested.

In many cases, a property owner or developer may need to seek zoning relief from the local Zoning Hearing Board (ZHB). Two common forms of relief are variances and special exceptions.

Variances are required when strict compliance with the zoning ordinance would create an unnecessary hardship due to unique characteristics of the property. Some examples include requests to reduce setback requirements for an addition to an existing structure, permission to exceed height restrictions, or relief from lot size or coverage requirements where compliance is physically impractical.

Special exceptions, despite their name, are uses that are conditionally permitted under the zoning ordinance but require approval from the ZHB. Some examples include multifamily housing in certain districts, daycare centers, and assisted living facilities.  Approval is not automatic in these instances, and the applicant must meet specific criteria outlined in the ordinance. The applicant must demonstrate that the proposed use will not negatively impact the surrounding community.

Zoning hearings are legal proceedings governed by strict procedural and evidentiary rules. Applicants bear the burden of proof and must present testimony, documents, and sometimes expert opinions to support their request. Opposition from neighbors or the municipality can further complicate the process.

Experienced zoning and land use counsel can evaluate the strength of a variance or special exception request, prepare persuasive legal and factual arguments, and coordinate with engineers, planners, and other experts. Additionally, legal counsel can ensure compliance with procedural requirements and deadlines and represent clients at the zoning hearing.


Without proper legal guidance, applicants risk denial, costly delays, or unfavorable conditions being imposed on their project.

Navigating Pennsylvania zoning laws requires careful planning, detailed knowledge of local ordinances, and skilled advocacy. Whether you are in the early stages of a project or facing a zoning challenge, having experienced legal counsel can protect your investment and help move your project forward efficiently.
