To be valid, what must a local zoning ordinance do?

A local zoning ordinance must reasonably promote community health, safety, and welfare to be considered valid. This requirement ensures that zoning regulations are designed to protect the interests and well-being of the community as a whole. A well-structured zoning ordinance considers factors such as the environment, public safety, and the overall quality of life for residents. This alignment with public interests fosters sustainable development, orderly growth, and the effective use of land.

The other options do not reflect the fundamental purpose of zoning ordinances. Favoring commercial developments over residential choices could lead to imbalances in community development and resident satisfaction. Describing an ordinance as unreasonable and restrictive contradicts the principles of fairness and just governance, as it can adversely affect property owners and disrupt community harmony. Lastly, serving only the interests of the municipality disregards the broader needs of the community, including residents and local businesses, which is contrary to the intended protective function of zoning laws.
