Ohio Commercial Building Permit Cost Estimator

Estimate the cost of a commercial building permit in Ohio based on your project's construction valuation, occupancy classification, and scope of work. Fees are based on Ohio Building Code (OBC) guidelines and typical municipal fee schedules.

Total estimated cost of construction including labor and materials
Gross floor area of the proposed structure
Total number of plumbing fixtures (toilets, sinks, drains, etc.)
Number of HVAC units requiring mechanical permit

Formulas Used

Base Building Permit Fee (ICC/OBC tiered valuation schedule):

  • ≤ $2,000 valuation → $50.00 flat
  • $2,001 – $25,000 → $50 + $8.00 per $1,000 above $2,000
  • $25,001 – $50,000 → $234 + $6.00 per $1,000 above $25,000
  • $50,001 – $100,000 → $384 + $4.50 per $1,000 above $50,000
  • $100,001 – $500,000 → $609 + $3.50 per $1,000 above $100,000
  • $500,001 – $1,000,000 → $2,009 + $3.00 per $1,000 above $500,000
  • > $1,000,000 → $3,509 + $2.00 per $1,000 above $1,000,000

Adjusted Base Fee = Base Fee × Occupancy Multiplier × Project Type Multiplier

Multi-Story Surcharge = Adjusted Base Fee × (Stories − 2) × 3% (for stories > 2)

Plan Review Fee = Adjusted Base Fee × 65% (standard) or × 97.5% (expedited)

Fire – Sprinkler = max($150, Sq Ft × $0.15)

Fire – Alarm = $250 + Sq Ft × $0.05

Plumbing = $35 + (Fixtures × $8.00)

Electrical = Tiered flat fee by service size + Sq Ft × $0.02

Mechanical = $50 + (HVAC Units × $25.00)

Ohio State Surcharge = Subtotal × 1% (ORC §3781.102)

Total = Subtotal + Ohio State Surcharge (minimum $75)

Assumptions & References

  • Fee schedule based on the ICC Building Valuation Data table adopted by most Ohio jurisdictions (Columbus, Cleveland, Cincinnati, etc.).
  • Occupancy multipliers reflect relative plan review complexity per Ohio Building Code (OBC) Chapter 3.
  • Plan review fee of 65% of permit fee is standard across most Ohio municipalities; expedited review adds a 50% surcharge to the plan review fee.
  • Ohio State Surcharge of 1% is mandated by Ohio Revised Code §3781.102 and paid to the Ohio Board of Building Standards (OBS).
  • Fire protection fees based on typical Ohio AHJ (Authority Having Jurisdiction) schedules.
  • Plumbing fees: $35 base + $8/fixture per Ohio Plumbing Code permit schedule.
  • Electrical fees based on service amperage tiers per NEC adoption in Ohio.
  • Mechanical fees: $50 base + $25/unit per Ohio Mechanical Code permit schedule.
  • Multi-story surcharge reflects increased structural and egress review requirements per OBC Chapter 5.
  • Demolition permits are estimated at 30% of equivalent new construction permit fee.
  • This tool does not include zoning fees, impact fees, tap-in fees, or third-party inspection fees, which vary significantly by jurisdiction.
