Summary
Evanston requires any vehicle burglar alarm to shut itself off within four minutes of activation and prevents it from re-triggering without being manually reset, under City Code Section 9-5-20(A)(4)(a). An alarm that runs longer, or that re-arms itself automatically, is treated as prohibited noise, and police can tow the offending vehicle to the City pound and bill the registered owner for the cost.
4.Vehicular Noise:a.Motor Vehicle Alarms: The use of a continuous, audible signal device which acts as a vehicle burglar alarm, when such device is not limited in operation to four (4) minutes after activation, and is capable of further activation without being reset to become active again. ... c.Police Authority to Abate: In addition to the general penalty provided in Section 1-4-1 of this Code, any violation of this Subsection (A)4. will automatically give the Evanston Police Department the authority to take reasonable measures to abate the noise or tow the vehicle to a City vehicle pound, and impose towing charges which shall be paid by the registered owner of the vehicle.d.Owner's Responsibility: Owners who violate this Subsection (A)4. shall assume the risk of any damage which may be caused by efforts of the City to abate the nuisance.

Full Breakdown
" In plain terms, an alarm has to cut itself off within four minutes and cannot simply retrigger on its own; if it does either, the device itself violates the ordinance regardless of how the vehicle came to be alarmed in the first place. The City backs that standard with real enforcement teeth: Subsection (A)(4)(c), "Police Authority to Abate," lets the Evanston Police Department "take reasonable measures to abate the noise or tow the vehicle to a City vehicle pound," with towing charges billed to the registered owner, on top of the general penalty in Section 1-4-1 of the Code.
Subsection (A)(4)(d) then puts the financial risk squarely on the owner: anyone who violates the alarm rule "shall assume the risk of any damage which may be caused by efforts of the City to abate the nuisance," meaning the City isn't liable if abating a runaway alarm, up to and including a tow, damages the vehicle. The alarm rule sits inside the broader Vehicles subsection of the noise ordinance, alongside separate bans on unmuffled exhaust, defective or overloaded vehicles that rattle or grind, and excessive horn use.
Violations & Fines
A vehicle alarm that runs past four minutes or re-triggers without a manual reset is enforced through the City's general noise-violation penalty in Section 1-4-1, and the Evanston Police Department is separately authorized under Subsection (A)(4)(c) to abate the noise directly or tow the vehicle to the City pound, with the registered owner billed for towing and assuming the risk of any resulting damage under Subsection (A)(4)(d).
