A residential area is a land used in which housing predominates, as opposed to industrial and commercial areas. Housing may vary significantly between, and through, residential areas. These include single- family housing , multi- family residential, or mobile homes. Zoning for residential use may permit some services or work opportunities or may totally exclude business and industry . It may permit high density land use or only permit low density uses. Residential zoning usually includes a smaller FAR ( floor area ratio) than business , commercial or industrial/ manufacturing zoning. The area may be large or small.
