Zoning regulations define how land can be utilized and are set forth by local governing bodies with authority from state, national or other enabling laws.

Building codes control building form, density of use, height limits and related facilities such as parking. They also include area zones and setbacks.

Density

Density plays an integral part in how spaces in neighborhoods are utilized. Density can be measured in terms of the size and footprint of buildings as well as unbuilt land on a property; changes to this factor can have drastic effects on how people use their homes as well as opposition from residents who prefer maintaining certain lifestyles.

At Cite Ouvriere, formal changes to house morphology were constrained by several regulations. These included an authorized footprint area of 60% of the plot, maximum allowed height of 11m and distances from neighboring buildings and street. Spacemate charts display these restrictions with moving dots showing their respective parameters.

Setbacks

Setback laws impact how space is utilized by dictating how close buildings or structures may come to established lot lines. These regulations aim to safeguard several interests and objectives such as improving residential views, protecting access to natural light sources, blocking pollution factories from being built near residential areas, permitting new housing development within existing neighborhoods, as well as offering safe off-street parking spaces.

These regulations may also regulate the size and configuration of front, back, side yards; off-street parking requirements; maximum building heights; minimum lot sizes and structures allowed on any given property. Some restrictions are mandatory while others are reviewed discretionarily by local land-use boards or officials based on due process including public notice and hearings; variances to these restrictions (called variances ) can only be granted following careful balancing between applicant benefits versus harm to neighboring properties.

Parking

Parking rules in NYC can be complex. Understanding the daily, hourly, curb condition and temporary signs requirements to avoid tickets is essential in avoiding tickets. Sometimes multiple rules apply simultaneously at one location, with the more restrictive rule always applying – for instance when near a fire hydrant you should stay six meters away (unless otherwise marked) so fire trucks have access to water; also do not park within 10 meters of pedestrian safety zones to allow free passage for walkers.

Developers were for decades required to include a certain minimum number of parking spaces when designing buildings, adding both costs and encouraging affordable housing tenants to subsidize private automobile ownership. Furthermore, large traditional parking lots can be detrimental to the environment by taking up valuable land area while increasing heat island effects and polluting stormwater runoff; communities have begun reviewing parking policies and requirements as a result.
