Building Code Questions
The City is required under State law to adopt the latest edition of the California Building Standards Code. This Code and Title 18 of the Long Beach Municipal Code establishes the uniform building standards for the construction and maintenance of buildings, electrical systems, plumbing systems, mechanical systems, and fire and life safety systems in the City. For additional information regarding the Code adopted by the City and the applicable year it is effective, please visit www.longbeach.gov/lbds/building/plan-review-service/code/.

- On the ceiling or wall outside of each separate sleeping area in the immediate vicinity of bedrooms.
- In each room used for sleeping purposes.
- In each story within a dwelling unit, including basements but not including crawl spaces and uninhabitable attics. In dwellings or dwelling units with split levels and without an intervening door between the adjacent levels, a smoke alarm installed on the upper level shall suffice for the adjacent lower level provided that the lower level is less than one full story below the upper level.
- In enclosed common stiarwells of apartment complexes and other multiple-dwelling complexes.
- In a Group R-3.1 occupancy, in addition to the above, smoke alarms shall be provided throughout the habitable areas of the dwelling unit except kitchens.
