Overview of Zoning Districts

Rialto organizes land into zoning districts that specify permitted uses, conditional uses and development standards. Typical district categories include residential, commercial, industrial and special purpose overlays. District maps and the full table of permitted uses are set out in the municipal zoning ordinance and map.

  • Residential districts: single-family, multi-family and mixed-use options.
  • Commercial districts: retail, office and service uses.
  • Industrial districts: manufacturing, warehousing and logistics.
Check the zoning map before buying or planning construction.

Density, Lot Coverage and Setbacks

Density rules control how many dwelling units are allowed per acre or per lot; lot coverage limits the share of a parcel that buildings may occupy; setbacks require minimum horizontal distances between structures and property lines. These standards vary by district and any overlay or specific plan that applies to a parcel.

  • Density metrics: units per acre or minimum lot size per dwelling unit.
  • Lot coverage: percent of lot allowed to be built upon.
  • Setbacks: front, side and rear yard distances from property lines.
Setbacks and coverage determine where you can place garages, additions and accessory buildings.
