What counts as project value

ICC Building Valuation Data table. Construction cost comes from ICC Building Valuation Data by construction type/occupancy and square footage. For one- and two-family dwellings the county prints: unheated sq ft x $31.50 + heated sq ft x $165.67 = construction cost. Commercial shell buildings use 80% of ICC valuation; contract price may be considered only under special circumstances.

Worked example: a $350,000 new home

  1. Building permit fee: $450.00 for the first $75,000.00 + $6.00 × 275 per $1,000.00 over = $2,100.00
  2. Technology fee: fixed = $15.00
  3. Site plan review fee: fixed = $100.00
  4. Certificate of Occupancy / Letter of Completion: fixed = $50.00
  5. Total before trade permits: $2,265.00.
