What does downzoning refer to in terms of zoning changes?

Downzoning refers to a change in zoning that results in a decrease of allowable density for a given area. This typically involves changing zoning classifications to allow for fewer building units or reduced height and mass of structures, ultimately reducing the potential for development intensity in that area. Such changes may be enacted to promote a particular type of development, protect neighborhood character, reduce traffic congestion, or preserve open space and natural resources.

In contrast, other options suggest scenarios that do not align with the concept of downzoning. For instance, changes that increase density or allow for more building units would be classified as upzoning, which is the opposite of downzoning. Limiting commercial property use can relate to specific restrictions within a zoning category but does not inherently change the density classifications of an area. Additionally, simply increasing zoning classifications without specifying the density does not define downzoning and may pertain to a broader reclassification of land uses.
