Do I need a permit for addition or structural alteration in Aurora?
Yes. In Illinois, addition or structural alteration generally requires a permit, and Aurora is no exception.
Additions and structural alterations require a permit in essentially all Illinois jurisdictions. Illinois has no statewide residential building code for this work, so the permit threshold is set by your municipality or county. The statewide codes that took effect on 1 January 2025 apply to commercial, public and state-funded buildings. Many local codes require zoning review for lot coverage and setbacks, and properties in a mapped flood zone face additional elevation requirements. A residential addition or structural alteration requires a plan-reviewed permit under the Aurora Enabling Code, the city's amended ICC I-Series codes, and Aurora offers design-development pre-review meetings to walk through requirements before you apply. The project must meet Aurora zoning setbacks and lot-coverage limits, a plat of survey is generally expected, and homes in a historic or Foxwalk district may also need a Certificate of Appropriateness. General and trade contractors generally must be registered with the Aurora Building and Permits Division, and the permit is filed, paid and inspected through the city's eTRAKiT online portal.
