PART D: NONVACANT SITES

Local governments with limited vacant land resources or with infill and reuse goals may rely on the potential for new residential development on nonvacant sites, including underutilized sites, to accommodate their RHNA. Examples include:

  • Sites with obsolete uses that have the potential for redevelopment, such as a vacant restaurant.

  • Nonvacant publicly owned surplus or excess land; portions of blighted areas with abandoned or vacant buildings.

  • Existing high opportunity developed areas with mixed-used potential.

  • Nonvacant substandard or irregular lots that could be consolidated.

  • Any other suitable underutilized land.

Local governments can meet other important community objectives to preserve open space or agricultural resources, as well as assist in meeting greenhouse gas emission-reduction goals, by adopting policies to maximize existing land resources and by promoting more compact development patterns or reuse of existing buildings.
