Estimate commercial building permit fees in Tennessee based on construction valuation, occupancy classification, and local jurisdiction multipliers. Results are estimates only — contact your local building department for exact fees.
Formulas Used
Building Permit Fee (sliding scale on valuation):
- ≤ $25,000 → $25.00 flat minimum
- $25,001 – $50,000 → $25 + $5.00 per $1,000 over $25,000
- $50,001 – $100,000 → $150 + $4.00 per $1,000 over $50,000
- $100,001 – $500,000 → $350 + $3.00 per $1,000 over $100,000
- $500,001 – $1,000,000 → $1,550 + $2.50 per $1,000 over $500,000
- > $1,000,000 → $2,800 + $2.00 per $1,000 over $1,000,000
Adjusted Building Fee = Base Fee × Occupancy Multiplier × Jurisdiction Multiplier × [1 + (Stories − 1) × 0.03]
Plan Review Fee = Adjusted Building Fee × 0.65
Electrical Fee = max($75, $75 + Sq Ft × $0.004) × Jurisdiction Multiplier
Plumbing Fee = max($60, $60 + Sq Ft × $0.003) × Jurisdiction Multiplier
Mechanical Fee = max($65, $65 + Sq Ft × $0.0035) × Jurisdiction Multiplier
Sprinkler Fee = $50 + ⌈Sq Ft ÷ 130⌉ × $0.12 (1 head per 130 sq ft)
State Surcharge = max($5, Adjusted Building Fee × 0.015)
Admin / Technology Fee = Adjusted Building Fee × 0.02
Total = Sum of all applicable fees above
