Summary
Oakland gives car alarms a hard fifteen-minute limit. Municipal Code § 8.18.010(C)(7) makes it an excessive-and-annoying-noise violation to let any exterior burglar or fire alarm, including a motor vehicle burglar alarm, keep sounding for more than fifteen minutes after it activates, and the same clock applies to alarms on buildings, not just cars.
Burglar or Fire Alarm. Sounding of any exterior burglar or fire alarm or any motor vehicle burglar alarm which is not terminated within fifteen (15) minutes of activation;

Full Breakdown
010(C)(7) is one of eleven specific acts the chapter labels excessive and annoying noise. It reaches 'any exterior burglar or fire alarm or any motor vehicle burglar alarm which is not terminated within fifteen (15) minutes of activation,' so the same fifteen-minute cutoff governs a car alarm in a driveway and a burglar alarm on a storefront. ; that testing rule is distinct from the fifteen-minute activation limit that applies once an alarm goes off and does not stop. Enforcement of the fifteen-minute rule follows the chapter's general procedure: subsection (D) requires an investigating official to issue a written or verbal warning to the person responsible before any citation issues, and the conduct becomes a violation only if the alarm noise persists more than fifteen minutes after that warning or recurs within a week.
16. Subsection (F) counts each day an alarm continues sounding beyond the limit as a separate offense, and subsection (C)(5) confirms the rule does not apply to alarms occurring for genuine emergency purposes.
Violations & Fines
An alarm that runs past the fifteen-minute mark exposes the responsible party to a written or verbal warning first under Section 8.18.010(D); an occurrence that continues past fifteen minutes after that warning, or recurs within a week, becomes an infraction under Chapter 1.28 with civil penalties or administrative citations available under Chapters 1.08, 1.12, and 1.16. Because each day counts as a separate offense under subsection (F), a repeatedly malfunctioning alarm system can generate a new citation every time it happens.
