About each permit

Certificate of Use and Occupancy

County Code Sec. 8-119 governs certificates of use and occupancy for buildings in unincorporated DuPage County. The fee for a single-unit commercial or industrial building is $200 up to 10,000 square feet and $300 over 10,000 square feet (not charged for commercial electrical work), and a multi-unit commercial or industrial building pays $100 per unit, per the Building & Zoning Schedule of Fees attached to Ordinance DC-O-0014-25, adopted by the County Board on March 25, 2025 and effective May 1, 2025 (County Code Sec. 8-114.3:1). A business inside a city or village deals with that municipality for occupancy instead.

Commercial Building Permit (with Plumbing and Electrical)

In unincorporated DuPage County, Building & Zoning issues building permits; 55 ILCS 5/5-1063 limits county building rules to buildings outside cities, villages and incorporated towns, so inside a municipality the city or village issues them. Figures are per the Building & Zoning Schedule of Fees attached to Ordinance DC-O-0014-25, adopted by the County Board on March 25, 2025 and effective May 1, 2025 (County Code Sec. 8-114.3:1). The industrial and commercial permit fee is $30.00 per $1,000 of construction cost, minimum $150, with remodeling at a $200 minimum; the schedule values new work per square foot by use group (Assembly $80, Business $75, Educational $75, Mercantile $65, Institutional supervised $65, Residential hotels $70, Factory and Industrial $50, Storage $45). A non-refundable application fee of $500 for new commercial buildings and additions or $150 for other commercial work is credited toward the permit. Commercial plan review runs from $150 to $485 by floor area plus $80 per additional 1,000 square feet. Commercial plumbing has a $100 minimum plus $15 per fixture, and commercial electrical a $100 minimum. Commercial drainage review (first review) is $80, $140 or $365 for up to 500, 1,500 or 4,999 square feet of disturbance, and the schedule adds a $200 administrative fee for processing unincorporated stormwater applications. Where work starts without a permit the normal fee is doubled.

Sign Permit

A business sign in unincorporated DuPage County needs a Building & Zoning sign permit. Advertising, business and portable signs cost $2.00 per square foot per face with a $100 minimum, and a sign with electrical work costs $50 more, per the Building & Zoning Schedule of Fees attached to Ordinance DC-O-0014-25, adopted by the County Board on March 25, 2025 and effective May 1, 2025 (County Code Sec. 8-114.3:1). A sign that needs a zoning variation pays the separate Zoning Board of Appeals fee. A business inside a city or village applies to that municipality instead.

Zoning Board of Appeals – Variation, Conditional Use and Rezoning

In unincorporated DuPage County, zoning relief goes through the Zoning Board of Appeals. Fees are per the Building & Zoning Schedule of Fees attached to Ordinance DC-O-0014-25, adopted by the County Board on March 25, 2025 and effective May 1, 2025 (County Code Sec. 8-114.3:1), and higher "violation" amounts apply where the petition follows a violation. For non-residential property a conditional use is $2,500 ($3,750 after a violation), a principal variation $1,500 ($2,250), and a sign variation $1,500 ($2,250). A day care home conditional use is $300 ($450) and a group day care home $500 ($750). Non-residential rezoning runs from $2,500 for less than 2 acres to $10,000 for 21 acres or more, an appeal is $1,500, and a planned development is $3,000 plus $100 per commercial building. A continuation may be charged at half the application fee and an additional appearance at $200. County zoning covers areas outside municipalities that have their own zoning ordinances (55 ILCS 5/5-12001).
