Anaheim Zoning Requirements

Each zone in Anaheim has different development standards. The table below shows setbacks (the minimum distance your building must be from each property line), maximum height, number of stories, lot coverage percentage, and Floor Area Ratio (FAR) for each residential zone.

Zone Front Side Rear Height Stories Coverage FAR
RM-4 — Multi-Family Residential 15' 10' 25' 35' 2 40%
Side setback increases with height.
RS-2 — Single-Family Residential 15' 5' 20' 35' 2 40%
Corner lots: 10' street-side setback.

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. ADUs only need 4' under California state law, regardless of what this table shows for primary structures.
  • Height — maximum building height measured from grade. Anaheim 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.

Frequently Asked Questions

How do I find my zone in Anaheim? +

Check Anaheim's planning department website for their zoning map, or search your address on our parcel search tool. Your zone code (R1, R2, etc.) determines which row in the table above applies to your property. You can also call Anaheim's planning counter for a quick zoning verification.

How long does plan check take in Anaheim? +

Initial plan review in Anaheim typically takes 4–8 weeks. If corrections are required (which is common), each resubmission adds another 2–4 weeks. Running a pre-submission plan check can eliminate the most common correction items and save one or more review cycles.

Can I build an ADU in Anaheim? +

Yes. Under California state law, Anaheim must approve ADUs that meet state standards — no discretionary review required. Detached ADUs can be up to 1,200 sqft with only 4' rear and side setbacks. Use our Anaheim ADU Eligibility Checker to see what you can build on your lot.

What are the most common reasons plans get rejected in Anaheim? +

The top reasons are setback violations (measuring from the wrong reference point), height calculation errors (using the wrong grade measurement method), lot coverage exceeding the zone limit, insufficient parking, and missing energy code (Title 24) compliance. See the "Common Plan Check Flags" section above for Anaheim-specific issues.

Do these codes apply to all projects in Anaheim? +

The zoning standards above apply to standard residential projects. Specific overlays (historic districts, hillside areas, coastal zones) may have additional restrictions. Commercial and mixed-use zones have different standards. Always verify your specific zone and any applicable overlays with Anaheim's planning department.
