Summary
Unincorporated Jackson County adopts the 2018 International Residential Code's Appendix G, which requires a compliant barrier, fencing, walls, or an approved pool cover with self-closing, self-latching gates, around outdoor swimming pools, spas, and hot tubs, enforced by the Public Works building permit process.
2018 International Residential Appendices ... G: Swimming Pools, Spas, and Hot Tubs ... As said publications may be amended, are adopted as the code of Jackson County for regulating the erection, construction, occupancy, equipment, use, height, area, and maintenance of all buildings or structures in the unincorporated area of Jackson County and on all Jackson County-owned real property, without regard to its location within the County.
Full Breakdown
Jackson County Code § 5400 folds the 2018 IRC's Appendix G, Swimming Pools, Spas, and Hot Tubs, into the county building code for the unincorporated area and all county-owned property. Appendix G sets the barrier standard model codes use nationwide: a fence, wall, or other approved barrier at least 48 inches tall, no gaps or footholds letting a 4-inch sphere pass, and any gate self-closing and self-latching with the release on the pool side above a child's reach. A permit from the Public Works building division is required before installation. Kansas City, Independence, Lee's Summit, Blue Springs, Raytown, and Grandview each enforce their own separate building codes, not this one.
Violations & Fines
Building or maintaining a pool without a required permit, or without a compliant Appendix G barrier, violates Chapter 54 and is punishable under § 5409 by up to one year in jail and/or a $1,000 fine, plus a stop-work order.
