Summary
Jackson County requires a building permit before any construction, alteration, or demolition work in the unincorporated area, adopting the 2018 International Building Code with local exemptions for small sheds, low fences, and other minor work.
It shall be unlawful for any person, firm, partnership, or corporation to erect, construct, enlarge, alter, repair, move, improve, remove, convert, demolish, equip, use, occupy, or maintain any building or structure, or cause or permit the same to be done without first obtaining a valid, unrevoked permit from the director of public works, as provided in this chapter, or to violate any other provision of this chapter.
Full Breakdown
Chapter 54 adopts the 2018 International Building Code, Residential Code, and related trade codes for unincorporated Jackson County and for all county-owned property regardless of location. Before erecting, altering, repairing, moving, or demolishing a building or structure, an owner must obtain a permit from the Director of Public Works under Jackson County Code Section 5409; doing the work first is a misdemeanor punishable by up to a year in jail and a $1,000 fine. County Code Section 5409.4 exempts small accessory sheds under 200 square feet, fences under 6 feet, low decks, and similar minor work from permitting. Kansas City, Independence, Lee's Summit, Blue Springs, Raytown, and Grandview enforce their own separate building codes.
Violations & Fines
Working without a permit is a misdemeanor: up to one year in county jail and a $1,000 fine under Section 5409. Premature occupancy adds a separate $500-$1,000 penalty.
