Are there any specific zoning restrictions in New Hampshire for farms?

April 5, 2026

Quick Answer

New Hampshire's zoning restrictions for farms can vary depending on the municipality, but generally, farms are allowed in agricultural districts and residential areas with certain permits. The state's Right to Farm Law (RSA 21-H) protects farmers from nuisance complaints if they follow best management practices.

Zoning Laws and Districts

New Hampshire has 13 agricultural districts, each with its own zoning regulations. Farms in these districts are allowed to operate with minimal restrictions, but some districts may have specific rules regarding building height, setback requirements, or access roads. For example, the Merrimack County Agricultural District allows farms in residential areas to operate with a special permit, but must adhere to zoning regulations.

Permits and Certifications

To operate a farm in New Hampshire, you may need to obtain various permits and certifications. For instance, the New Hampshire Department of Agriculture, Markets, and Food (DAMF) requires farms to register with the state and obtain a permit for the sale of raw milk. Additionally, the New Hampshire Department of Environmental Services (DES) may require permits for activities such as well installation, septic system installation, or pesticide application.

Best Management Practices

To comply with New Hampshire’s Right to Farm Law, farmers must follow best management practices (BMPs) to minimize the impact of their operations on neighboring properties. BMPs may include practices such as manure management, irrigation management, and pest management. The New Hampshire Department of Agriculture, Markets, and Food provides guidelines and resources for farmers to implement BMPs and maintain a safe and healthy environment for both their operations and the surrounding community.
