Regulatory framework
The code baseline for Champaign County.
Champaign County Zoning Ordinance as amended through December 18, 2025; Special Flood Hazard Areas Ordinance; and Storm Water Management and Erosion Control Ordinance. The County has not identified an adopted general structural building-code edition for unincorporated areas; its permit review is for zoning, land use, placement, size, height, floodplain, and stormwater compliance. Relevant public-use construction plans must document Illinois Environmental Barriers Act/ADA compliance, and specialized uses such as Tier-2 battery energy storage systems must meet applicable NFPA 855 requirements.
