How permitting works in Illinois
Illinois counties have the authority to regulate construction in unincorporated areas, but the state does not require them to do so for residential buildings. The county's role is highly discretionary; some counties have professional building departments, while others only require permits for high-density commercial projects or flood-plain management.
Strong Home Rule; no mandatory state residential code.
