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. Fort Worth 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.

How long does plan check take in Fort Worth? +

Can I build an ADU in Fort Worth? +

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

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 Fort Worth-specific issues.

Do these codes apply to all projects in Fort Worth? +

The zoning standards above apply to standard residential projects. Specific overlays (historic districts, hillside areas, coastal zones) may have additional restrictions.
