A municipal charter is a legal document that establishes a city or town's government structure, powers, and functions. It serves as a constitution for local governments, outlining how they operate, the roles of elected officials, and the rights of citizens. Charters can vary widely, reflecting the unique needs and preferences of each community. Municipal charters are typically created through a process involving local voters or state legislatures. They can be amended or revised to adapt to changing circumstances or to improve governance. This flexibility allows municipalities to address specific issues, such as zoning laws or public services, effectively.
