Henry County, Illinois
Colona is a city in Henry County, Illinois. Colona adopts its own zoning, so inside its limits Colona’s rules apply, not the county’s. 7 rules below are quoted from official sources and independently re-checked, most recently on November 2, 2026. Rules for unincorporated land are on the Henry County page.
Construction of a new building inside Colona city limits; the quoted sentence sits in the trailer-coach section, so it is a city permit trigger for new buildings
“unless a permit to do so is obtained as required for the construction of a new building”
Energy-efficient building envelope and mechanical, lighting and power systems inside Colona city limits (International Energy Conservation Code, 2012 edition)
adopted edition: 2012 edition
“the international energy conservation code, 2012 edition, as published by the international code council, be and is hereby adopted as the energy conservation code of the city of colona, in the state of illinois”
“the international residential code, 2012 edition, including appendix chapters c, e, g, i and j (see international residential code section 101.2.1, 2012 edition), as published by the international code council, be and is hereby adopted as the residential code of the city of colona, in the state of illinois”

“title 9 building regulations title 10 mobile homes and mobile home parks title 11 subdivisions title 12 zoning title 13 flood control”
Trailer coaches (vehicles built to be towed or moved on public streets) occupied as a dwelling inside Colona city limits; not a general RV rule
“it shall be unlawful to occupy for sleeping or other residence purposes any trailer coach which has been rendered immobile by the removal of wheels or placing the same on a foundation or on the ground unless such trailer coach in question and location complies with the provisions of this code and other regulations applicable to single-family dwellings.”
Division of land inside Colona city limits under the city's subdivision title
“title 9 building regulations title 10 mobile homes and mobile home parks title 11 subdivisions title 12 zoning title 13 flood control”
New or expanded driveways and walkways connecting a lot to a public street or alley inside Colona city limits
concrete driveway minimum thickness: >= 4 inches (no variance) · concrete driveway maximum width: <= 30 feet (without obtaining a variance)
“no driveway or walkway connecting any lot or tract with a public street or alley upon which such lot abuts shall be constructed unless a permit therefor has been first obtained.”
We looked and could not find an official answer yet. Silence is not permission; ask Colona or Henry County directly.
Each answer was extracted from an official source and independently re-checked against that source by a second reviewer. That is an evidence check, not legal advice. Rules change; confirm with the authority before you buy or build.
Unanswered questions are usually a sign that Colona publishes no rule on the point, not that none exists. Henry County’s page lists the county offices to call.
