What type of zoning controls the amount of space used for buildings in a given area?

Bulk zoning regulates the physical dimensions of buildings and the amount of space they occupy on a parcel of land. This type of zoning establishes limits on factors such as the height of buildings, the total floor area, and the spacing between buildings (setbacks). By doing so, bulk zoning aims to control how densely areas can be developed, thus influencing neighborhood character, ensuring adequate light and air, and preventing overcrowded conditions.

In contrast, other types of zoning have different focuses. Use zoning pertains to the specific functions that properties can serve, such as residential, commercial, or industrial uses. Overlay zoning adds additional regulations or incentives on top of existing zoning to achieve certain objectives, such as environmental protection or historic preservation. Incentive zoning offers bonuses in terms of additional building rights or height in exchange for providing public benefits, like affordable housing or park space. Thus, bulk zoning is the correct answer as it specifically addresses the spatial usage of buildings in a jurisdiction.
