Summary
Jackson County's noise ordinance requires any motor vehicle burglar alarm to shut off within 15 minutes of activation, and treats more than two false activations of the same alarm in a calendar month as a separate violation.
Sounding or permitting the sounding of any exterior burglar or fire alarm or any motor vehicle burglar alarm, shall terminate within fifteen (15) minutes of activation unless an emergency exists. If a false or accidental activation of an alarm occurs more than twice in a calendar month, the owner or person responsible for the alarm shall be in violation of this chapter.

Full Breakdown
Jackson County Code § 5564.d.2 caps how long a motor vehicle burglar alarm may run: it must terminate within 15 minutes of activation unless a real emergency is underway. If the same alarm has more than two false or accidental activations in one calendar month, the owner or responsible person is in violation of Chapter 55. The Sheriff has primary enforcement responsibility for the chapter's noise rules (§ 5566.a). Chapter 55 states it applies countywide, but Kansas City, Independence, Lee's Summit, Blue Springs, Raytown and Grandview each maintain their own separate municipal codes, so residents inside those city limits should check their city's ordinance for alarm rules, not this county provision.
Violations & Fines
A conviction under Chapter 55 (§ 5520) is punishable by a fine up to $1,000, up to one year in the county jail, or both.
