Aurora, Illinois Building Permits
Plan Aurora, Illinois building permits with local guidance on costs, review timelines, zoning, code requirements, inspections and stamped plans.
Wind
ASCE 7 basic wind speed: typically 115 mph ultimate 3-second gust for Risk Category II buildings in the Aurora area; final wind design depends on exposure category, risk category, height, and the adopted code edition.
Snow Load
Ground snow load: commonly about 25 psf in northeastern Illinois, with roof design adjusted for drifting, roof geometry, exposure, thermal condition, and unbalanced snow loading.
Flood
Aurora uses FEMA Flood Insurance Rate Maps and local floodplain regulations. Floodplain concerns occur along the Fox River, Indian Creek, Blackberry Creek, and other drainageways. Projects in Special Flood Hazard Areas may require floodplain development permits, elevation data, compensatory storage, and flood-resistant materials or elevated utilities.
Earthquake
Seismic risk is relatively low in the Aurora area; many ordinary structures are designed as Seismic Design Category A or B depending on site class and risk category. Commercial, essential, or unusual structures require ASCE 7 site-specific seismic design confirmation.
Wildfire
Wildfire risk is generally low in urban and suburban Aurora. The city generally relies on standard building and fire code provisions, fire separation, roof covering, exterior wall, and fire access requirements rather than special wildland-urban interface construction standards.

Approval Timeline
Simple residential permits may be issued over the counter or within about 3 to 10 business days when the application is complete. Residential additions, garages, decks with structural complexity, and new single-family homes commonly take 2 to 4 weeks for initial review. Commercial tenant build-outs, restaurants, industrial work, mixed-use projects, and new commercial buildings often take 3 to 6 weeks or longer depending on fire review, engineering, stormwater, zoning, and resubmittal cycles.
Common Requirements
Typical Aurora submittals include a completed permit application, contractor registration, project valuation, property address and owner information, site plan or plat of survey, construction drawings, floor plans, elevations, framing details, foundation details, structural calculations when required, energy code compliance forms, truss drawings, mechanical/electrical/plumbing layouts for trade work, fire suppression or alarm drawings when applicable, and product specifications for items such as windows, doors, roofing, or decks. Exterior work must show setbacks, easements, lot coverage, drainage impacts, and utility conflicts.
Zoning Information
Aurora zoning regulates land use, setbacks, height, lot coverage, parking, signs, accessory structures, home occupations, and planned developments. The city includes residential, business, office/research, industrial, downtown, and special zoning districts, with additional standards for historic areas, floodplains, corridors, and planned development approvals. Because Aurora spans multiple counties, site-specific zoning, subdivision, stormwater, and county-related records should be confirmed early in the design process.
Permit Costs
Aurora permit fees vary by work type, valuation, square footage, and required inspections. Small residential permits such as fences, sheds, roofing, and water heaters are often in the tens to low hundreds of dollars. Decks, remodels, garages, and additions commonly range from a few hundred dollars to more than $1,000 depending on scope. New homes and commercial projects are usually calculated by valuation or square footage and can range from several thousand dollars upward, with separate fees for plan review, fire review, engineering, impact fees, or reinspection when applicable.
Engineering Requirements
Stamped plans or calculations from an Illinois-licensed design professional are typically required for new commercial buildings, commercial alterations, changes of occupancy, structural modifications, beams, columns, foundations, retaining walls, large decks, unusual framing, fire-damaged structures, and engineered systems such as trusses or precast components. Residential projects may need engineered details for long-span beams, point loads, underpinning, foundation modifications, tall retaining walls, or work outside prescriptive IRC limits.
Local Code Adoption
Aurora enforces locally adopted International Codes with city amendments, commonly including the International Building Code and International Residential Code, along with the Illinois Plumbing Code, Illinois Accessibility Code, Illinois Energy Conservation Code, adopted electrical code, fire code, and local ordinances. Applicants should verify the current adopted IBC/IRC edition with the City of Aurora Building & Permits Division before final design because local code editions and amendments can change by ordinance.
Typical Projects
Common Aurora permit projects include single-family additions, decks, fences, sheds, basement finishes, garage construction, kitchen and bath remodels, roof and siding replacements, solar panels, new homes, commercial tenant build-outs, restaurants, warehouse and industrial improvements, fire alarm and sprinkler work, and downtown or corridor redevelopment projects.
