Zoning changes to facilitate the use of lower-cost housing types overview
While each of these types of housing tends to be more affordable than certain other housing types, their availability depends in part on the provisions laid out in the local zoning ordinance or code. For example, some zoning policies specify that there may be only one dwelling unit per parcel of land (restricting the development of accessory dwelling units) or prohibit the use of manufactured housing or multifamily housing in particular residential districts. Some local jurisdictions must revise their zoning policies to allow for development of these types of units in some or all parts of town.
