Pennsylvania has no statewide law banning or expressly permitting backyard chickens, so under Pennsylvania backyard chickens laws your right to keep a flock depends almost entirely on your municipality’s zoning code, your homeowners association, and a short list of state requirements that apply even to a few hens. The Pennsylvania Municipalities Planning Code gives boroughs, townships, and cities the power to regulate land use within their borders, which is why your neighbor across a township line can face completely different rules. Before buying chicks or building a coop, check three layers of authority: your local zoning ordinance, any HOA restrictions on your property, and animal health and environmental rules from the Pennsylvania Department of Agriculture.
Your Municipality Decides Whether Hens Are Allowed
Animal and land-use decisions in Pennsylvania sit at the municipal level, not the county or state level. Each borough, township, and city independently decides whether chickens are permitted in residential zones and under what conditions. Some welcome small flocks with minimal paperwork. Others ban poultry outright in anything denser than agricultural zoning.
Local codes classify chickens as either pets or livestock, and that distinction drives most of what follows. A livestock classification usually triggers stricter rules on lot size, waste handling, and how far coops must sit from property lines. Setbacks vary widely: some municipalities require 15 or 20 feet from the nearest property line, while others push coops 50 feet or more away in denser neighborhoods. You will need to check your zoning map to confirm your parcel sits in a district that allows accessory agricultural uses at all.
A few patterns are nearly universal across Pennsylvania municipalities that do allow hens:
- Flock caps of four to six hens on smaller residential lots.
- A ban on roosters, driven by noise complaints.
- Minimum coop and run dimensions tied to the number of birds.
- Sanitation and rodent-control requirements for feed storage.
Violating placement, density, or noise standards can lead to daily fines until the problem is fixed, and in some cases the municipality can order the birds removed and revoke your permit.
How Philadelphia and Pittsburgh Handle It
Because local rules swing so widely, the two biggest cities give useful reference points. Philadelphia permits up to six hens on residential property. Roosters are classified as farm animals and are not allowed. Coops must provide at least one square foot of enclosed space per hen, plus a run with at least two square feet per hen.1Philadelphia City Council. Philadelphia Backyard Chickens Ordinance A special permit is not required for small flocks that meet these standards.
Pittsburgh treats backyard chickens as an urban agriculture accessory use and permits them by right on occupied residential lots, meaning no permit is needed for personal use. On a lot of at least 2,000 square feet you can keep five chickens or ducks. Every additional 1,000 square feet of property adds one more bird. Roosters are prohibited. All structures and roaming areas must stay sanitary, and feed must be kept in rodent-proof containers inside an enclosed structure.2City of Pittsburgh. Pittsburgh Urban Agriculture Zoning Code
Both cities are relatively permissive. Many smaller boroughs and townships are stricter, and some ban backyard poultry entirely. Start by calling your municipal zoning office or pulling the code online before you make any plans.
Your HOA Can Still Say No
Even if your borough or township allows backyard chickens, a homeowners association can prohibit them. The covenants, conditions, and restrictions you agreed to when you bought the home are enforceable private contracts that operate independently of municipal zoning. If the HOA documents say no livestock or no poultry, that restriction stands no matter what the local government permits.
Pennsylvania courts routinely enforce these private agreements. Ignore the restriction and the association can sue for an injunction forcing you to remove the birds and recover its attorney fees in the process. Pull out your deed and HOA documents and read the animal clauses before you buy chicks, build a coop, or file for a municipal permit.
Getting a Permit
In municipalities that require a permit, the process starts at your local zoning office. You will typically need to gather:
- A site plan showing the proposed coop and run placement relative to your house, property lines, and neighboring structures.
- Coop dimensions and a description of materials, since many codes require roughly three to four square feet of indoor coop space per bird and about ten square feet of outdoor run space per bird, and the structure must be predator-proof, ventilated, and compliant with local accessory-structure building standards.3Reserve Township.

- Proof of ownership, usually a deed copy or recent tax bill. Tenants generally need a notarized letter from the landlord granting permission.3Reserve Township. Reserve Township Backyard Chicken Application
- A neighbor notification form in some areas, confirming adjacent owners were told about the pending agricultural use.
Permit fees generally run between $25 and $100, depending on whether the charge is one-time or annual. Review timelines vary, but expect two to four weeks. A zoning officer or code enforcement official will often inspect the property to verify the coop matches your submitted plan and does not interfere with utility easements or drainage. Once approved, the permit remains valid as long as you keep meeting sanitation, noise, and density standards.
If Your Permit Is Denied
You have the right to appeal a zoning officer’s denial to your municipality’s Zoning Hearing Board. Under the Municipalities Planning Code, the Board has exclusive jurisdiction over appeals from zoning officer determinations, including permit denials.4Pennsylvania General Assembly. Pennsylvania Municipalities Planning Code You can also apply for a variance if your property does not technically meet the zoning requirements but the restriction creates an unnecessary hardship.
The hearing is quasi-judicial. You present evidence, testify, and can call witnesses. Request a court reporter. If you later need to appeal the Board’s decision, a complete transcript is critical to building your case.
If the Board also denies your request, you can appeal to the Court of Common Pleas in the county where your property is located. The appeal must be filed within 30 days of the Board’s written decision. That deadline is strictly enforced and treated as jurisdictional, so missing it by a day will likely end your case.4Pennsylvania General Assembly. Pennsylvania Municipalities Planning Code The court reviews whether the Board abused its discretion, made legal errors, or issued findings unsupported by substantial evidence. Expect several months from filing to decision.
State Rules That Apply Even to a Small Flock
Premises Registration
The Pennsylvania Department of Agriculture runs a Premises Registration program that assigns a unique identification number to each physical location where livestock are kept. The system lets animal health officials quickly identify where birds are during a disease outbreak or food safety emergency.5Pennsylvania Department of Agriculture. PDA Licensing and Certification Programs Registration is free and can be completed through the department’s online portal or by email.
Under the Domestic Animal Law, avian influenza is designated a dangerous transmissible disease, and the department has broad authority to regulate the keeping and handling of domestic animals to contain or eliminate it. That authority includes establishing quarantines and, in serious cases, ordering the depopulation of infected flocks.6Pennsylvania Code and Bulletin. Interstate/International Quarantine Order – Avian Influenza
Manure Management Plan
This one catches most new chicken keepers off guard. Pennsylvania environmental rules require every livestock operation to maintain a written manure management plan, regardless of size. Even four hens trigger the requirement. The plan does not need to be written by a certified specialist, and nobody has to approve it, but you must keep it on your property and produce it if asked.
For a small backyard flock the plan is straightforward: describe your composting method, how often you clean the coop, and where the waste ends up. Larger operations exceeding eight animal equivalent units (roughly 8,000 pounds of live animal weight) or hitting a density of two animal equivalent units per acre must prepare a formal Nutrient Management Plan under Act 38, which does require professional involvement. A handful of chickens will not come close, but even a simple written plan keeps you in compliance with the Clean Streams Law.
Animal Welfare
Pennsylvania’s animal neglect statute applies to anyone with a duty of care over an animal, including poultry owners. Under Title 18 of the Pennsylvania Consolidated Statutes, failing to provide necessary food and potable water, access to clean and sanitary shelter with weather protection sufficient to retain body heat and stay dry, or necessary veterinary care qualifies as neglect.7Pennsylvania General Assembly. Pennsylvania Code Title 18 Chapter 55 – Responsible Animal Ownership A first offense is a summary offense carrying a fine of $50 to $750, up to 90 days in jail, or both. If the neglect causes bodily injury or places the animal at imminent risk of serious injury, the charge rises to a third-degree misdemeanor. The statute carves out “normal agricultural operations,” but hobbyists not producing for market should assume the neglect provisions apply to them.
Biosecurity
Highly Pathogenic Avian Influenza remains an active concern for all poultry keepers, backyard flocks included. The USDA’s Defend the Flock program provides free biosecurity checklists and educational materials specifically for small flock owners, covering perimeter buffer areas and routine biosecurity auditing.8USDA Animal and Plant Health Inspection Service. Defend the Flock Resource Center The materials are voluntary; the underlying risk is not. A single infected bird can trigger a state quarantine that shuts down your entire flock.
Selling the Eggs
If your hens produce more than your household can eat, Pennsylvania allows small-scale sales. Producers with fewer than 3,000 laying hens who sell eggs within five days of the lay date, predominantly within a 100-mile radius of their facility, fall under a streamlined set of regulations.9Commonwealth of Pennsylvania. Eggs – Food Safety Eggs sold directly to consumers at the farm, roadside stands, or farmers markets must be refrigerated during transport and sale, clean and free of cracks, and packaged in cartons with required labeling.
Producers selling 100 dozen eggs or fewer per week directly from their own flock can sell ungraded eggs and generally do not need a state license. Sell through retail stores, restaurants, or wholesale channels and the eggs must meet USDA shell egg grading standards (Grade AA, A, or B) and comply with stricter packaging and labeling rules.
Selling poultry meat is a different and more regulated process. Under a federal producer exemption, you can raise and slaughter fewer than 20,000 birds per year on your own premises without USDA inspection, but the meat must be labeled with your name, address, safe handling instructions, and the statement “Exempt P.L. 90-492.” All sales under this exemption must stay within Pennsylvania. Selling across state lines requires full USDA inspection.
