Local ordinances are laws or regulations enacted by local government authorities, such as municipalities or counties, to govern specific areas within their jurisdiction. These ordinances address a variety of issues, including zoning, public health, and safety, and can vary significantly between different localities, reflecting the unique needs and values of the communities they serve. Understanding local ordinances is essential in the context of preemption, as state or federal laws may limit or override the authority of local governments to legislate on certain matters.
