Formula & Fee Components
Total Permit Cost = Adjusted Permit Fee + Plan Check Fee + SMIP Fees + CALGreen Fee + Energy Review + Story Surcharge + Fire Review + Accessibility Fee + Tech Surcharge + State Surcharge
- Adjusted Permit Fee = Base Fee (ICC tiered table) × Occupancy Multiplier × Jurisdiction Multiplier × Project Type Modifier
- Base Fee (ICC Tiered Table):
- ≤ $2,000: $69.25 flat
- $2,001–$25,000: $69.25 + $14.00 per $1,000 over $2,000
- $25,001–$50,000: $391.25 + $10.10 per $1,000 over $25,000
- $50,001–$100,000: $643.75 + $7.00 per $1,000 over $50,000
- $100,001–$500,000: $993.75 + $5.60 per $1,000 over $100,000
- $500,001–$1,000,000: $3,233.75 + $4.75 per $1,000 over $500,000
- > $1,000,000: $5,608.75 + $3.65 per $1,000 over $1,000,000
- Plan Check Fee: 65% of adjusted permit fee (85% for I/H occupancies; 50% for tenant improvements)
- SMIP Seismic Fee: 0.013% of valuation (California Geological Survey)
- Local SMIP Fee: 0.010% of valuation
- CALGreen Surcharge: $0.10–$0.21/sq ft depending on jurisdiction (Title 24 Part 11)
- Title 24 Energy Review: $350–$2,800 tiered by square footage
- Multi-Story Surcharge: 3% of adjusted permit fee per story above 2
- Fire & Life Safety Review: 18–25% of adjusted permit fee (A, E, H, I, R occupancies only)
- Accessibility Review: $0.05/sq ft (min $200) for new/addition; $0.03/sq ft (min $150) for TI
- Technology Surcharge: 3–5% of adjusted permit fee

Assumptions & References
- Base fee table derived from the ICC Building Valuation Data fee schedule, widely adopted by California jurisdictions (International Code Council).
- Occupancy classifications per California Building Code (CBC) 2022, Chapter 3.
- Plan check fee at 65% of building permit fee per standard California municipal practice (e.g., City of Los Angeles, City of San Diego fee schedules).
- SMIP fee of 0.013% per California Geological Survey Strong Motion Instrumentation Program fee schedule (commercial occupancies).
- CALGreen surcharge per Title 24, Part 11 (CALGreen) and local green building program fees.
- Title 24 Part 6 energy compliance review fees based on typical California jurisdiction schedules.
- Fire & Life Safety review fees based on California Fire Code (CFC 2022) and local fire department fee schedules.
- Accessibility review per CBC Chapter 11B (California accessibility standards, stricter than federal ADA).
- State surcharge represents combined levies from the Building Standards Commission (BSCC), Housing & Community Development (HCD), and Division of the State Architect (DSA).
- Jurisdiction multipliers reflect documented fee differentials: large California cities typically charge 25–40% more than small jurisdictions due to higher labor costs and administrative overhead.
- This estimator does not include: utility connection fees, school impact fees (Education Code §17620), traffic impact fees, sewer/water capacity fees, or soils/geotechnical review fees.
- Actual fees must be confirmed with the local Authority Having Jurisdiction (AHJ) prior to permit application.
