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 Missouri, municipal law encompasses the regulations and ordinances that are specific to cities, towns, or counties within the state. These laws are designed to address a variety of local concerns and are enforced by the municipal government. Key areas of municipal law include zoning laws, which dictate how land within the municipality can be used and developed; property and sales tax regulations; and local services such as trash collection, water, and sewer management. Municipal law also covers regulations on noise and odor pollution, fire safety and open burning restrictions, and the powers of local police. Additionally, municipalities in Missouri are responsible for the inspection of residential and commercial buildings to ensure they meet safety standards, and they have the authority to condemn buildings that are deemed unsafe or unfit for use. Each municipality in Missouri may have its own set of ordinances and codes that reflect the unique needs and priorities of the local community.
