Building functions affect a street. Zoning codes govern the location of different types of buildings and such physical features as maximum height. Zoning codes usually separate residential, commercial, and industrial buildings. Usually, one type of building predominates on a street. However, a street can combine several types of buildings and a building can house more than one use.
Residential buildings are where people live.
Single-family houses, row houses, and apartment buildings are types of residential buildings. People relaxing, children playing, curtains in windows, bicycles and baby carriages in front of buildings indicate a residential street. Commercial buildings are used for buying and selling goods and services. Shops, stores, signs, transportation facilities nearby, daytime activity, and nighttime calm characterize a commercial street. Industrial buildings are used for manufacturing and storing goods.
