Livestock Zoning and Space Requirements

Who decides how many animals I can keep?

Several layers can apply at once. A town or county zoning ordinance may limit species and numbers. A deed restriction or homeowner association can be stricter than the law. Health codes may set rules for manure, odor and distance to wells and neighbors.

These rules vary a great deal by state, county and town, so a neighbor's experience in another county may not apply to you. Do not rely on memory, rumors or an old real estate listing. Even long-time owners get surprised. Parcels that look like farmland can be zoned residential, and rules sometimes change when land is divided or sold, so check each parcel on its own.

Which offices should I contact?

Start with your county or town zoning or planning office. Ask for the zoning district of your parcel and what agricultural or animal uses are allowed in it. Then ask your county health department about manure, waste and setbacks from wells and water.

Also check with your state department of agriculture about animal registration, premises identification or disease program rules. Your county extension office can often explain local practice and put you in touch with other keepers. Some counties publish their ordinances online, but a phone call or visit clears up what the text leaves open. Ask for the planner's name and number so you can follow up.

What questions should I ask?

Ask which species are allowed and whether there is a limit per acre or per parcel. Ask about minimum lot size, setbacks from property lines, houses, wells and streams, and whether any permit or inspection is required.

Ask how noise, odor, manure storage and fencing are regulated, and whether a nonconforming use or an exemption is possible. Write down who you spoke with and the date, and ask for the answer in writing where you can. Keep notes on any promise a real estate agent or seller made about animals. Written zoning answers carry weight, while casual remarks do not.

How much space do animals actually need?

Space needs depend on species, breed size, the quality of your pasture, rainfall, how long animals stay in one place and whether you feed hay. Published numbers vary widely, and none is universal.

Your extension office and NRCS conservation planners can help you estimate carrying capacity for your soil and climate. A soil survey and a look at your pasture condition are better guides than a rule of thumb. Acreage figures used by agencies and animal groups are often called animal units or stocking rates. Ask your extension office what these terms mean locally and how they are applied before you rely on them.

What else takes up room besides pasture?

Plan for shelter, feed and hay storage, water points, handling areas, quarantine space, manure storage and paths for vehicles. Animals also need dry, shaded spots and safe loading areas.

Setbacks and drainage can take large parts of a small lot out of use. Mark these on a sketch before you count usable acres. Count the footprint of vehicles, trailers and equipment that come with animals. Delivery trucks and hay wagons need turning room, and so does a veterinarian's truck in an emergency. Do not forget a place for sick or new animals. An isolation pen takes real room, and it is much easier to plan it now than to find space during an illness.

What if the rules do not allow what I want?

Ask whether a variance, conditional use permit or different zoning district is possible, and what the process involves. Some places allow small numbers of certain animals even where larger herds are not allowed.

If the answer is no, consider a different species, a smaller number or a different property. It is better to learn this before buying animals than after a complaint. If you are new to a county, attend a planning board meeting or read minutes. You will learn how the board handles agricultural questions and what neighbors tend to raise.

What should I do this week?

Find your parcel number, then call your zoning office and ask for the zoning district and the animal rules that apply. Write down the answers, the date and the name of the person who gave them.

Then call your county health department and your state department of agriculture with the questions on your list. If any answer is unclear, ask for the ordinance number so you can read it yourself.
