Summary

Oakland's Housing Code requires every smoke and carbon monoxide alarm installed in a residential building to have captive screws or another tamper-resistant method preventing removal, and to be kept in proper working order. A unit missing a required smoke or CO alarm altogether can be declared substandard and a public nuisance.

Where installed in residential buildings or structures, approved devices used to detect the products and components of combustion (smoke alarms) and carbon monoxide (CO detectors) shall have captive screws or other approved method to preclude unauthorized tampering or removal of the device and shall be maintained in proper working order.

Full Breakdown

320 requires that any smoke alarm or carbon monoxide (CO) alarm installed in a residential building or structure have captive screws or another approved method that prevents unauthorized tampering or removal, and be kept in proper working order at all times. 08), which incorporates California Health and Safety Code § 17910 et seq. 340(A)(18) lists 'lack of smoke detector and carbon monoxide alarms' among the conditions that render a residential or non-residential building substandard and a declared public nuisance, alongside missing heat, hot water, and required ventilation.

350, requiring the owner to obtain permits and start repairs within 30 calendar days and finish within 60, with extensions available at the Building Official's discretion. 125. 5, can arrest a violator they reasonably believe committed a misdemeanor Housing Code offense in their presence. A first infraction conviction is punishable by the maximum fine allowed by law; a fourth violation within one year can be charged as a misdemeanor carrying county jail time. A certified judgment for unpaid fines or costs against an owner can be recorded with the Alameda County Clerk-Recorder.

Violations & Fines

Tampering with or removing a required smoke or CO alarm, or letting one fall out of proper working order, is a Housing Code violation under § 15.08.320. Combined with a missing alarm, it can support a finding under § 15.08.340(A)(18) that the unit is substandard and a public nuisance, triggering a 30-day permit deadline and 60-day repair deadline under § 15.08.350. Violations are treated as strict-liability infractions carrying the maximum fine allowed by law; a fourth violation within a year can be charged as a misdemeanor with possible county jail time under § 15.08.110.

Frequently Asked Questions

Does Oakland require carbon monoxide alarms in rental units?
Oakland's Housing Code treats a missing smoke or CO alarm as a substandard condition under § 15.08.340(A)(18), and any alarm that is installed must have captive screws or another tamper-resistant method under § 15.08.320. Together the two sections function as a mandate: landlords who skip or disable a CO alarm risk a public-nuisance declaration against the property.
Can I remove the screws on my CO alarm to swap the battery?
No. Section 15.08.320 requires captive screws or another approved method specifically to prevent unauthorized tampering or removal, not just to block battery access; the device itself must stay mounted and functional at all times. Detaching the alarm from its mount without restoring the tamper-resistant fastening violates the code.
What happens if my Oakland apartment is cited for a missing CO alarm?
The Building Official can find the unit substandard and a public nuisance under § 15.08.340(A)(18) and issue a declaration under § 15.08.350 requiring permits within 30 days and completed repairs within 60. Owners may appeal to a Hearing Officer within the timeframe set under § 15.04.1.125 before the order becomes final.
Can I be arrested for a Housing Code violation in Oakland?
Yes, in limited circumstances. Section 15.08.110 lets the Building Official and designated officers arrest a person under California Penal Code § 836.5 if they reasonably believe the person committed a misdemeanor Housing Code offense in their presence; a fourth infraction conviction within one year can itself be charged as a misdemeanor.
