A component of Euclidean zoning that imposes restrictions on the physical characteristics of land and buildings, including minimum lot sizes, setbacks, building heights, and floor area ratios.
Aisha Ahmed sought a special use permit to convert a large residence into a supervised group home for adults with intellectual disabilities. The city denied the permit solely because of neighbors' discomfort with the residents' mental condition, without citing any traffic, density, or safety data. The denial violated equal protection because the zoning action rested on prejudice rather than a legitimate governmental interest.
Artemis Logistics operated a warehouse built to a height permitted under prior area zoning rules.

Some jurisdictions permit amortization ordinances that require termination of a nonconforming height after a reasonable period based on the owner's investment and the nature of the use.
A vested right arises when the owner makes substantial expenditures in good-faith reliance on a permit or existing area zoning such that applying new bulk restrictions would be inequitable.
Public land-use regulations including area zoning are not servitudes within the meaning of the Restatement because they arise from governmental authority rather than private agreements running with land.
