Answers from the rulebook for Smithfield

Rules another office applies inside Smithfield

Smithfield does not set these itself; the county, a health district or the state does, and they apply to every address inside its limits.

  • Local zoningPresent

    Land inside the incorporated city of Smithfield. Zoning here is the Henry County Zoning Ordinance, a county-administered joint ordinance covering the county and its incorporated cities, not a Smithfield-only city ordinance. Its official zoning map is certified for Smithfield.

    • Smithfield does not appear to have a separate city zoning ordinance in the sources found.
    • The ordinance's adoption by the Smithfield city council is asserted only by a third-party permit site and is not confirmed on an official page.
    • Parcel-level zone for a given Smithfield lot was not checked against the official zoning map.
    • The same ordinance also governs unincorporated Henry County; this claim does not answer for unincorporated land alone.
    “this is to certify that this is official zoning map for henry county and the cities of eminence, new castle, campbellsburg, pleasureville and smithfield kentucky”
  • Zoning districtsPublished

    Zoning districts that apply inside the incorporated city of Smithfield under the Henry County Zoning Ordinance

    • The district map was not opened; the district for a given Smithfield parcel is unverified.
    • Overlay districts (including Small Lot Residential, SLR) modify the principal district for the items they address.
    “henry county is divided into eleven principle districts as shown on the zoning map.”
  • Minimum lot sizeDistrict specific (with conditions)

    Lots inside the Small Lot Residential (SLR) overlay district within the incorporated city of Smithfield, where there is no public sewer

    • Applies only where no public sewer is available; the overlay exists to keep small lots without sewer service legal.
    • Overlay regulations take precedence only for the items the overlay addresses; other principal-district rules still apply.
    • Overlay districts may only be changed through actions initiated by the planning commission.

    minimum lot area with no public sewer: >= 10000 square feet (applies only in the SLR overlay where no public sewer is available)

    “in the slr overlay district, the minimum lot area with no public sewer shall be 10,000 square feet.”
  • Living in an RVLimited

    Recreational vehicle parks (not individual RV occupancy on private lots) inside Smithfield city, where the zone is R-3, B-2 or A-3 on the official map

    • RV parks may be permitted only as a conditional use approved by the planning commission.
    • The park must meet the listed criteria, including that it will not be detrimental to the health, safety or general welfare of persons in adjacent areas.
    • Individual RV occupancy on private land is not addressed in the sections read.

    minimum RV park size: >= 5 acres · minimum lot area per RV space: >= 2500 square feet (20% of lots may be as small as 1,200 square feet, but these may be used by tent campers only)

    “recreational vehicle parks may be permitted as conditional use in r-3, b-2 and/or a-3 districts provided they meet the following criteria, and provided further that they are approved by the commission”

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