McHenry County, IL Public Conduct: Loitering Rules (2026)

McHenry County's Building Use Ordinance, adopted under 55 ILCS 5/5-1005 and 55 ILCS 5/5-1015, governs conduct at every County-controlled building and its grounds. 110. 040(G) makes it unlawful to loiter, initiate disorderly conduct, or engage in any conduct that creates a nuisance, reasonably obstructs entrances, foyers, lobbies, corridors, offices, elevators, stairways, or parking lots, impedes county employees' official duties, or keeps the public from conducting business in a timely manner. The same section separately bars destroying county property, throwing objects at county buildings, climbing on buildings, camping on the grounds, and erecting tents or signs without authorization, so loitering sits alongside a broader list of building-use prohibitions rather than standing as a standalone park or sidewalk rule.

150 assigns enforcement to the McHenry County Sheriff across every county-controlled facility. 00 for any violation of the ordinance, and specifies that the county fine does not replace or excuse any other applicable state or local law covering the same property. Because the ordinance reaches "County controlled property" broadly, it applies to courthouse grounds, the county administration complex in Woodstock, and other county facilities, not to sidewalks or private business property outside county control.
