A state statute that delegates to municipalities the power to enact zoning ordinances regulating the use of privately owned land. The statute supplies the specific grant of authority required because a general police power delegation does not extend to zoning. Municipalities may exercise only the powers expressly conferred or necessarily implied by the enabling act.
Zuri Zhang sued a municipal planning board in federal court under diversity jurisdiction after the board denied her rezoning application. She served the complaint on the planning director under the federal rule for service on a municipal corporation. The board moved to dismiss, citing a stricter state statute that required service only on the city clerk. The court denied the motion because the federal rule controlled.
Zander Ziegler and other landowners filed a diversity class action alleging that a new zoning restriction violated their rights. State law barred class treatment of claims seeking only monetary relief from land-use rules. Ziegler moved to certify under Federal Rule of Civil Procedure 23. The court granted certification because the federal rule governed the procedural question.

Zeke Zhao, representing low-income residents, challenged a township zoning ordinance that permitted only large-lot single-family homes. The township defended the ordinance as authorized by the state zoning enabling act. The court held that the enabling act required zoning to serve the general welfare, including regional housing needs, and invalidated the restrictions.
Zara Zhang sought rezoning for a commercial development. After the city council approved the change under the zoning enabling act, voters petitioned for a referendum. The developer argued the referendum process exceeded the act's delegation. The court upheld the referendum as consistent with the enabling act's reservation of legislative power.
Zack Zuniga challenged a state statute that withdrew delegated zoning power from municipalities over certain residential uses. The statute was adopted after the enabling act had granted zoning authority to local governments. The court struck down the statute because it improperly curtailed authority granted by the enabling act without repealing the delegation.
Zara Zuberi owned a historic terminal and sought to develop the air rights. The city applied its landmarks law, enacted under the zoning enabling act, to block the project. Zuberi claimed a taking. The court held that the designation was a valid exercise of the police power delegated by the enabling act and did not constitute a taking.
The act supplies the specific legislative grant that allows a municipality to adopt zoning ordinances. A general police power delegation is insufficient. Without the enabling act, the municipality lacks power to zone.

Some state constitutions grant home-rule municipalities the power to zone as if they were the legislature. In those jurisdictions the municipality may choose to act under home-rule authority rather than the enabling act. Most states still require compliance with the enabling act even for home-rule cities.

The Standard Zoning Enabling Act authorizes regulation but not prohibition of uses. Some courts therefore hold that amortization provisions are unenforceable if the act does not expressly permit them. Other courts uphold reasonable amortization periods as valid exercises of the delegated regulatory power.

Zoning ordinances adopted under the enabling act must still satisfy substantive due process and equal protection. The act itself incorporates the requirement that regulations promote public health, safety, morals, or the general welfare. An ordinance that violates these standards is invalid even if it follows the procedural steps of the enabling act.
