Peoria, IL Accessory Structures: Shed Rules (2026)

Peoria classifies storage sheds as accessory structures under Appendix B (Zoning Ordinance), enforced by the Community Development Department's Building Safety Division at 419 Fulton Street Room 203 (309-494-8600, communitydevelopment@peoriagov.org). The Accessory Structure Permit is listed as a standard residential permit at peoriagov.org/269/Permits. Appendix B's residential district provisions typically require sheds to sit in the rear or side yard (not the front yard between the front building line and the street), with minimum side and rear setbacks from property lines, a maximum height typically in the 12-15 foot range, and a cap on the total combined area or footprint of accessory structures on the lot (often expressed as a percentage of lot or rear yard area). Permit submissions include a site plan showing the shed location and dimensions, distances to all property lines and other structures, height and material specifications, and the foundation type. Sheds on permanent foundations may have additional plan review under the IRC as adopted through Chapter 5 (Buildings) of the Code. Sheds may not contain habitable space (no kitchens, sleeping accommodations, or independent bathrooms that would make them an unauthorized second dwelling under the ADU prohibition). Historic District properties face additional Historic Preservation Commission review. HOA-governed properties may impose architectural and material restrictions under the Illinois Common Interest Community Association Act (765 ILCS 160/) that are enforceable separately from the city standards. Confirm the current size threshold below which no permit is required (often around 120-200 sq ft in IL cities) with Building Safety.
