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 Wyoming, municipal law encompasses the legal framework governing cities, towns, and counties within the state. This includes ordinances and regulations specific to each municipality, which are enacted by local governing bodies such as city councils or county commissions. Municipal law covers a wide range of issues including zoning laws, which dictate land use and development; property and sales tax regulations; and services such as trash collection, water, and sewer management. Additionally, municipal law in Wyoming addresses environmental concerns like noise and odor pollution, sets fire and burning restrictions, and outlines the extent of police powers. Local governments are also responsible for the inspection of residential and commercial buildings to ensure compliance with safety and building codes, and they have the authority to condemn buildings that are deemed unsafe or unfit for use. These laws are designed to maintain public order, protect the health and safety of residents, and promote the general welfare of the community within the municipality.
