Answers from the rulebook for Colona

Colona’s own rules

    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

    • Construction may proceed once the permit is obtained, so status is conditional.
    • Contractors doing business in the city must register and show license and insurance/bonding proof and pay a $50 annual registration fee (9-1-10(a)-(b)).
    • The general building permit section (9-1-1 Adopted Codes, 9-1-4 Building Inspector, 9-1-5 Permit Fees) was not retrieved; fee and application rules are not confirmed here.
    “unless a permit to do so is obtained as required for the construction of a new building”

    • Only the code table of contents was opened; the Title 12 zoning text itself was not retrieved, so district rules and administration are not verified here.
    • The table of contents places Title 12 under the city's own code, so this claim does not rely on county zoning.
    “title 9 building regulations title 10 mobile homes and mobile home parks title 11 subdivisions title 12 zoning title 13 flood control”
  • Living in an RVLimited

    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

    • A trailer coach rendered immobile by removing wheels or placing it on a foundation or the ground may be occupied only if it and its location comply with the code and rules for single-family dwellings (9-1-9(d)).
    • Converting a trailer coach to permanent attachment needs a permit (9-1-9(c)).
    “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.”
  • Subdividing landRegulated (with conditions)

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.
