For California apartments, smoke alarms should be checked at move-in/when a new tenancy starts, whenever a tenant reports a problem, and as part of regular property inspections or maintenance visits. Many landlords also check them annually or semi-annually and document the date, unit, alarm locations, condition, and any battery/replacement work completed.
California law generally makes the owner responsible for testing and maintaining required smoke alarms, and the tenant is responsible for notifying the owner/manager if they become aware an alarm is not working. If you need to enter the unit to inspect, test, repair, or replace alarms, provide proper written notice unless it is an emergency. In California, 24 hours’ written notice is generally presumed reasonable for entry, absent other facts.
It is also a good idea to check carbon monoxide alarms at the same time, remind tenants not to remove batteries or disable alarms, and keep written records/photos showing compliance.
