Answers from the rulebook for Calvert City

Calvert City’s own rules

  • Local zoningPresent (with conditions)

    Land inside Calvert City city limits. Calvert City administers its own zoning ordinance (the Calvert City zoning ordinance) through its Planning Commission and zoning administrator; this is not a county rule.

    • A zoning compliance certificate from Calvert City is required for new construction, alteration, moved or enlarged structures, or a change of use before the building permit application, per the Marshall County and Calvert City pages.
    • Marshall County's own page states the county has no zoning regulations, so this claim does not extend to the unincorporated county.
    • The ordinance text itself could not be opened on the official site in this research pass (the calvertcity.com ordinance PDF returned 404); district and use details are not stated here.
    “marshall county does not have zoning regulations; however, the cities of benton and calvert city do have zoning requirements that must be adhered to during the permitting and construction process.”
  • Permit feesPublished (with conditions)

    • The fee is shown on the form dated rev 3/2022 and the form does not state an effective date.
    • Only the zoning compliance fee is published; building permit and other fees were not located on official pages.

    zoning administrator fee, residential: 15 USD (zoning compliance certificate only) · zoning administrator fee, commercial: 25 USD (zoning compliance certificate only)

    • Application goes to the Calvert City Planning Commission and zoning administrator at 861 E 5th Avenue, Calvert City; the form lists 270-395-7138.
    • The Marshall County page says a zoning permit or letter of compliance must be produced for the building permit application; the county building permit steps were not found on official pages.

Unanswered questions are usually a sign that Calvert City publishes no rule on the point, not that none exists. Marshall County’s page lists the county offices to call.
