Building requirements
Building a house in San Francisco, CA: what the code requires
Statewide residential code
- Building code
- California Residential Code (Title 24, Part 2.5) applies statewide, with local amendments common in larger cities.
- Energy code
- California Energy Code (Title 24, Part 6) is one of the strictest in the US. New homes generally require solar PV, and all-electric readiness rules apply.
- Climate zone
- IECC climate zone 2–6. Insulation, windows and HVAC are sized to match.
- Typical frost depth
- 0–12 in (coast/valleys), 18–36 in (mountains). Footings must extend below the local frost line (confirm with your building department).
- Foundations
- Raised or pier foundations where flood zones apply; slab inland.
- Who can draw the plans
- Single-family homes can generally be designed by a non-licensed home designer. A licensed engineer's stamp is often required for structural items, engineered foundations or special hazard zones, or when the local building official asks for it.
- Engineer stamp
- If your jurisdiction requires sealed drawings, add our California Engineer Stamp / Permit-Ready package ($1,500).
California-specific rules & hazards
- CALGreen (Title 24, Part 11) green-building requirements apply to all new homes.
- Wildland-Urban Interface areas (Fire Hazard Severity Zones) require Chapter 7A ignition-resistant construction.
- Seismic design is required statewide, and plans often need engineered lateral (shear wall) calculations.
- Coastal Commission permits may apply within the coastal zone.
- Seismic bracing, shear walls and hold-downs
- Wildfire-resistant materials and defensible-space detailing
- Flood-zone elevation and coastal foundation requirements
Summary for planning only. Codes, editions and local amendments change, so always confirm current requirements with the building department that will issue your permit. Our designers check your jurisdiction before drawing.
