Municipal law generally includes the laws and ordinances specific to a city, town, or county—also known as a municipality. Municipal law often addresses legal issues for which the city or town government is responsible for enforcing—such as zoning restrictions, land use and development, property taxes, sales taxes, trash pickup and disposal, water and sewer service, noise pollution, odor pollution, fire and burning restrictions, police powers, inspection of residential and commercial buildings, and condemnation of buildings.

In New Jersey, municipal law encompasses the regulations and ordinances that are specific to cities, towns, or counties within the state. These laws are typically enacted by the local governing body, such as a city council or town committee, and address a wide range of issues that fall under the jurisdiction of the municipality. This includes zoning laws, which regulate land use and development to ensure the orderly growth of communities; property and sales tax ordinances; and local services such as trash collection and water and sewer provision. Municipalities in New Jersey also have the authority to enforce regulations related to noise and odor pollution, impose fire and burning restrictions, exercise police powers, and conduct inspections of residential and commercial properties. Additionally, local governments have the power to condemn buildings that are deemed unsafe or unfit for occupancy. The specific provisions and enforcement mechanisms of municipal law can vary significantly from one locality to another within New Jersey, reflecting the unique needs and priorities of each community.
