Farm Zoning and Land Use Rules

What is zoning and who sets it?

Zoning is a set of local rules that divides land into districts and says what uses are allowed in each. Counties, townships and towns usually write and enforce these rules, so they differ from one place to the next, even within a state.

Some rural areas have little or no zoning, while others regulate everything from lot size to roadside stands. Never assume your parcel is free of rules because your neighbor seems to do what he likes.

Because rules are local, advice from a friend in the next county may not help you. The only reliable answer is the one from the office that enforces the rules where your parcel sits.

What activities does zoning commonly touch?

Zoning questions come up whenever you change how land is used. A new barn, a second home, a farm stand, farm tours, event hosting, a processing kitchen or a large number of animals can each raise questions.

Ask the planning office what applies to your parcel before you spend money, not after. Retrofitting a structure to meet a rule is much harder than planning for it.

Even where no permit is required, other agencies may be involved for things like food sales, wells, septic systems and animal waste, so ask who else you may need to contact.

• New buildings and building permits
• Farm stands and on-farm sales
• Agritourism, events and visitors
• Livestock numbers and setbacks
• Signs, driveways and road access
• Home businesses or processing space

How do you look up the rules for your parcel?

Start with the county or town planning or zoning office. Ask which district your parcel is in, what uses are allowed, and whether a permit, variance or special approval is needed for your plan. Request the answer in writing when you can.

Many counties also post zoning maps and ordinances online. If anything is unclear, speak with a staff member directly, because summaries on websites can be out of date.

What are nonconforming uses and variances?

Sometimes an older use existed before a rule changed, and local rules may allow it to continue under certain conditions. A variance is a formal exception to a rule, granted through a local process.

These terms carry specific meanings in your jurisdiction. Ask the planning office to explain how they apply, and consider an attorney for anything involving significant investment.

How does agricultural zoning relate to other programs?

Land use rules may connect to farmland preservation programs, tax assessment programs and conservation agreements. Each has its own rules, and a choice in one can affect the others.

Check with the county assessor, your extension office and the planning staff, and keep copies of everything you receive.

What should you do before buying or building?

Before a purchase, ask the seller what permits exist for current buildings and whether anything was built without approval. Talk to neighbors, and attend a planning meeting if you can, to learn how the community treats new uses.

If you are unhappy with a decision, there are usually appeal and public comment processes. Learn them early, and stay civil, since you will live beside these officials and neighbors for years.

Bring a sketch of what you plan, with distances to roads and property lines. Staff can answer specific questions much faster when they can see the plan.

What if zoning rules change after you buy?

Communities change their rules, and growth can bring new restrictions or new pressure from neighbors. Following local planning agendas is a simple way to hear about changes before they affect you.

If a proposed change would hurt your farm, you can usually speak at a public meeting or send written comments. Be specific and calm, explain how your operation works, and invite officials to visit. People who understand farming are more likely to write fair rules, and local farm organizations and extension offices can sometimes help you prepare your comments.
