Which document designates the legally permitted land uses within a mapped area?

• A. Building codes
• B. Zoning maps
• C. Plans
• D. Deeds

Answer: (B)

Zoning directs what can be done with land in different parts of a city by dividing the area into zones that specify allowed uses and development rules. The document that visually communicates these rules across a mapped area is the zoning map, which is part of the zoning ordinance. It shows the boundaries of each zone and, together with the ordinance, tells you whether a parcel can be used for housing, retail, factories, etc., and what restrictions apply. Building codes govern construction methods and safety standards, not land-use permissions. Plans relate to proposed projects or planning documents, not the official map of permitted uses. Deeds record ownership and any private restrictions, but they do not set the legally permitted uses for an entire mapped area.
