BuildingPermitCost How DuPage County calculates your permit fee
The county charges a building permit fee using a fee table based on project value, with a $50.00 minimum. Plan review is a separate charge: its own fee table. Electrical, plumbing and mechanical work gets its own permits.

Single family / townhomes, new construction and additions
| Project value | Fee |
|---|---|
| Over $0 | $10.00 per $1,000 or fraction |
Single family / townhomes, remodeling

Industrial and commercial, remodeling
| Project value | Fee |
|---|---|
| Over $0 | $30.00 per $1,000 or fraction |
What counts as project value
Higher of your bid or the valuation table. Valuation comes from the county's cost schedule (e.g. single-family new construction $90 per sq ft of all areas within outside walls; decks/patios $10/sq ft; accessory structures $10 or $30/sq ft); if the applicant's valuation is higher, the higher figure prevails. Remodeling is based on cost of construction.
Worked example: a $350,000 new home
- Building permit fee: $0.00 for the first $0.00 + $10.00 × 350 per $1,000.00 over = $3,500.00
- Plan review fee: table value for 2,400 sq ft: $235.00 = $235.00
- Total before trade permits: $3,735.00.
