The validity of zoning is based on the police power reserved to the states.

Zoning is a governmental power that enables the regulation of land use and development within a particular area. The constitutionality of zoning is based on the police power, which the states hold the authority over. The police power refers to the power of the government to regulate and restrict private property rights for the benefit of the public welfare, health, and safety. Therefore, zoning is a valid exercise of the police power held by the states.
