What it takes to build here — permits, zoning, and septic — scouted from Hamilton County’s own official sources.
Hamilton County's official department list includes no building/zoning or permit office; as a non-home-rule Illinois county there is no statewide residential building-code mandate, and no county building-permit program exists for unincorporated areas (permits are handled within municipalities such as McLeansboro). State overlay (IL): P.A. 103-0510 (2025) exempts new residential construction from its inspection requirement and only sets a code floor for jurisdictions that already have codes; in non-code counties the IRC attaches only via builder-purchaser contracts (815 ILCS 670/15). The Illinois Plumbing Code applies statewide.
