Answers from the rulebook for Charlack

Charlack’s own rules

  • Building code adoptedPartial

    Charlack city occupancy (minimum housing) inspections of dwellings inside city limits

    • The page says the inspection uses local and county ordinances and the BOCA code; it does not cite a dated adoption ordinance or an edition of the BOCA code.
    • Whether Charlack adopts a construction code for new building is not established here; eCode360 Chapter 500 (building regulations) was not opened.
    “the city performs a “minimum” housing inspection using local, county ordinances and the boca code.”
  • InspectionsRequired

    Dwellings inside Charlack city limits that are sold or rented, and any dwelling before a person moves in (city occupancy/housing inspection)

    • Triggered by sale or rental of the home and by moving a person into a dwelling; the page does not describe inspections for owner-occupied dwellings that are neither sold nor newly occupied.
    • The inspection is a city 'minimum' housing inspection; it does not replace the buyer's or tenant's own inspections.
    • The city may file municipal court charges, condemn the dwelling, or seek injunctive relief if a person is moved in before passing inspection.
    “no person may be moved into a dwelling before passing an inspection.”
  • Certificate of occupancyRequired

    Dwellings inside Charlack city limits: an occupancy permit is required before residents move in (city's Ordinance 505.070 as summarized by the city)

    • Occupancy without a permit is an ordinance code violation subject to fines under the city's municipal code.
    • The city page cites Ordinance 505.070; the ordinance text itself was not opened because eCode360 chapter pages were not reachable.
    “prior to moving in, residents are required to obtain an occupancy permit.”
  • Driveway accessLimited

    Driveway surface condition checked in Charlack city occupancy inspections; this is not a driveway access, curb-cut or driveway-approval permit

    • Applies to the occupancy inspection checklist only.
    • eCode360 Chapter 535 (sidewalks and driveway approaches) was not opened, so any driveway-approach permit requirement is not established.
    “all driveways shall be concrete or asphalt.”
  • Permit feesPublished (with conditions)

    Charlack city occupancy permit and occupancy inspection fees for dwellings inside city limits

    • Fees as stated on the city's House Inspection Checklist page; the ordinance text (505.070) and a full fee schedule were not located.
    • Reinspections are subject to additional fees; the page does not state the reinspection amount beyond the $10.00 per additional attempt.

    occupancy permit one-time fee: 20 USD · occupancy inspection initial cost: 50 USD · additional occupancy inspection attempt fee: 10 USD (for each attempt after a failed or incomplete first attempt)

    “the initial cost of inspection is $50.00. if the inspection cannot be completed or fails the first attempt an additional $10.00 will be required for each attempt that follows.”

    • The inspector may refuse an inspection if the dwelling is not ready (for example a cleaning crew present or work under way).

    • Process for construction building permits is not described on this page.
