ZoningDefinitionA law that regulates the orderlydevelopment of land.• Divides areas into districts or “zones” (e.g. “zoning”).• Regulates: • Use (residential, commercial, manufacturing) (e.g. “land use”), • Form (tall, low, detached, row- house), and • Density (house - apartment building, shop - department store).• For “the public health, safety and general welfare” of a city or town• A police power of government
ZoningHistoryUntil the early 1900’s, land was virtuallyunregulated. Construction was generallyregulated only by:1. Building Codes (building height, floor area, lot coverage, courts, windows),2. ‘Nuisance’ laws (restricted certain objectionable uses (e.g. a slaughterhouse) within a city from being near another, ‘sensitive’ use (e.g. housing), and3. Deed restrictions (private agreements that were part of the property ownership that limited its use by its owner).
ZoningHistoryInitial goals of zoning:1. Protect residential areas from - ‘objectionable’ uses (i.e. industry), - overcrowding, and2. Control new building construction.
ZoningPurpose and Nature• “public health, safety and general welfare”,• Orderly growth,• Protect property values,• Raise or increase density,• Increase residential, commercial and manufacturing development,• Manage aesthetics,• Provide for public amenities (plazas, waterfront, open space),• Provide for different types of housing (affordable, artists), and• Protect the environment (planting requirement, bicycle facilities).
ZoningZoning (generally) does NOT: Regulate architecture/ aesthetics of a building, Control building materials, (typically) Spur growth/ development where there is no market demand, Preserve a building or structure, Regulate the brand of business that may use a piece of land (e.g. Walmart), and Retroactively discontinue a use (in almost all cases).
