What it takes to build here — permits, zoning, and septic — scouted from Clark County’s own official sources.
The county's official departments and permits pages list no building department or building permit; only highway-related permits (truck, utility, culvert) are issued, consistent with Illinois non-home-rule rural counties not requiring county building permits. 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.
