In most lower density districts, there are specific maximum perimeter wall heights above which the building usually must have a pitched roof or be set back before rising to the permitted building height. Typically, building height is determined by the interplay of zoning regulations with a developer's design and economic concerns. In general, space must be provided between certain types of residential buildings on the same zoning lot according to a special formula. In order to provide adequate light and air to windows on courts, minimum court sizes are established. In addition, there are also requirements for the amount of space which must be provided in front of legally required windows.
Parking Zoning laws also require the provision of off-street parking for most new developments.
Parking on the site of a new development helps eliminate congestion on nearby streets. In areas where additional parking would generate more traffic than desirable, and where mass transit is available, the requirement for on-site parking is reduced or eliminated. Off-street loading berths for commercial and manufacturing uses may be required. The size and placement of signs are also regulated in each zone. Performance Standards Manufacturing uses and certain intense commercial uses are subject to performance standards which limit noise, air pollution and other nuisance-creating activity.
