How to Read This Table

  • Front setback — minimum distance from the street-facing property line to your building. Typically the largest setback. Eaves and architectural features may project 2–3' into this area.
  • Side setback — minimum distance from each side property line. May increase for two-story construction in some zones. Corner lots have a "street side" setback that's usually larger.
  • Rear setback — minimum distance from the back property line. In some states, ADUs have reduced setback requirements (e.g., 4' in California) regardless of what this table shows for primary structures.
  • Height — maximum building height measured from grade. Moreno Valley may measure from average grade, lowest adjacent grade, or midpoint of the roof — check your specific zone for the measurement method.
  • Coverage — the maximum percentage of your lot that can be covered by buildings. Includes the footprint of all structures — main house, garage, ADU, and covered patios.
  • FAR — Floor Area Ratio. Total floor area of all buildings divided by lot area. A FAR of 0.45 on a 5,000 sqft lot means maximum 2,250 sqft of building. Use our FAR Calculator to check yours.
