A municipal regulatory scheme that divides land into districts and restricts permissible uses within each district. The scheme is valid when the classification is reasonable and bears a substantial relation to public health, safety, morals, or general welfare. Application of the scheme to a particular parcel may be invalid if the restriction lacks that relation or rests on prejudice rather than a legitimate governmental interest.
Zelda Zavala applied for a special-use permit to operate a group home for adults with intellectual disabilities in a residential zone. The city council denied the permit after neighbors expressed concerns about the residents' mental condition. A court reviewing the denial finds no legitimate governmental interest and holds the action violates equal protection.
Zebulon Zimmerman sought rezoning of a single parcel from residential to commercial use. The city council approved the change after a hearing, but surrounding owners sued, alleging the amendment singled out one lot without advancing public welfare.

Zuri Zhang purchased land near a commercial district but found the zoning map placed the parcel in a strict residential classification that barred all beneficial development. Zhang sued, arguing the boundary line as applied bore no substantial relation to public welfare and arbitrarily deprived the owner of property use.
Zara Zhang owned undeveloped acreage on the edge of a growing city. The city adopted a comprehensive zoning ordinance dividing the municipality into residential, commercial, and industrial districts. Zhang challenged the residential classification of the parcel. The court upholds the ordinance as a valid exercise of police power because the districts bear a reasonable relation to public welfare.
Zeta Biotech proposed converting a motel into short-term housing near a planned state development. Local zoning rules limited density in the area. The company argued the rules were more restrictive than other land-use measures. The court notes that ordinary zoning laws validly restrict private property uses when they advance community planning goals.
Zhao Commerce owned a historic terminal building subject to landmark preservation rules enacted under the city's zoning authority. The rules prevented full development of air rights above the structure. The owner challenged the restrictions as a taking. The court weighs the economic impact against the character of the comprehensive land-use regulation.
Classifications involving persons with intellectual disabilities receive rational basis review. Even under that standard the government may not act from mere prejudice. A denial of a special-use permit for a group home that rests solely on the residents' mental condition lacks a legitimate governmental interest and violates equal protection.

Rezoning occurs by amending the zoning ordinance or map after notice and hearing. The amendment must bear a substantial relation to public health, safety, morals, or general welfare. Spot zoning that singles out one parcel for inconsistent treatment without a public purpose may be invalid.

A regulatory zoning ordinance, which would be clearly valid as applied to the great cities, might be clearly invalid as applied to rural communities.
