Occupancy Classification
A – Assembly (restaurants, theaters, churches) B – Business (offices, banks, outpatient clinics) E – Educational (schools, daycare) F – Factory/Industrial H – High Hazard I – Institutional (hospitals, nursing homes) M – Mercantile (retail stores, markets) R – Residential (hotels, apartments 4+ units) S – Storage (warehouses, parking garages) U – Utility/Miscellaneous
Total Building Square Footage
Gross floor area of the proposed structure
Number of Stories
Project Type
New Construction Addition to Existing Building Alteration / Renovation Change of Occupancy Demolition
Fire Protection System
None Sprinkler System Only Fire Alarm System Only Both Sprinkler & Fire Alarm
Plumbing Fixtures (count)
Total number of plumbing fixtures (toilets, sinks, drains, etc.)
Electrical Service Size (Amps)
No Electrical Permit Needed Up to 200A 201A – 400A 401A – 800A 801A – 1600A 1601A – 3200A Over 3200A
HVAC Units (count)
Number of HVAC units requiring mechanical permit
Expedited Plan Review?
Standard (included in base fee) Expedited (additional 50% surcharge)

#### Formulas Used
Base Building Permit Fee (ICC/OBC tiered valuation schedule):
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
- Ohio State Surcharge of 1% is mandated by Ohio Revised Code §3781.102 and paid to the Ohio Board of Building Standards (OBS).
