Which zoning category primarily considers density?

The correct choice focuses on residential zoning, which is specifically designed to regulate the density of housing in a given area. Density in this context refers to the number of housing units allowed per acre or a specified area, which is crucial for urban planning and development. Residential zoning impacts how many homes can be built, influencing the overall population density, infrastructure needs, and community services necessary in that zone.

This zoning category also addresses factors such as the type of residential developments allowed, whether single-family homes, multi-family units, or townhouses, contributing directly to the character and structure of neighborhoods.

Commercial zoning, while it does have regulations, typically deals with business operations and might not focus primarily on density. Retail zoning, a subset of commercial zoning, is primarily concerned with the types of goods sold and store operations rather than residential density. School and governmental zoning involves institutions and public land use, which, although important, does not pertain to residential population density in the same way residential zoning does.
