How permitting works in Knox County
Illinois has no single statewide residential building code — municipalities (many home-rule) adopt and enforce their own codes. Statewide minimums include the Illinois Plumbing Code (IDPH, licensed plumbers required), the Illinois Energy Conservation Code, and the Illinois Accessibility Code. Zoning, signs, fences, and right-of-way permits are entirely local.
