Summary
Lafayette's PMC requires smoke alarms in every sleeping area, every room along the escape path from a bedroom, and every story of a dwelling, including the basement, under Sec. 26-284(b). Alarms in a unit must be interconnected so one activates them all, and each must be powered from the building's wiring with battery backup.
(b)Single- and multiple-station smoke alarms. Single- and multiple-station smoke alarms shall be installed in existing Group 1-1 and R occupancies in accordance with [section] 26-284(b)(1) through 26-284(d).(2)Single- or multiple-station smoke alarms shall be installed in all of the following locations in Group R-1:a.In sleeping areas.b.In every room in the path of the means of egress from the sleeping area to the door leading from the sleeping unit.c.In each story within the sleeping unit, including basements. For sleeping 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.

Full Breakdown
Sec. 26-284(b) applies the smoke alarm mandate to existing Group I-1 (institutional) and Group R (residential) occupancies. For Group R-1 units it lists three specific locations: in the sleeping area itself, in every room a person would pass through escaping from the sleeping area to the unit's exit door, and in each story of the sleeping unit including basements, with a narrow allowance for split-level units where one alarm can cover both levels if the lower level sits less than a full story below. Sec.
26-284(c) requires that where more than one alarm is required in a unit, they must be interconnected so activation of one sounds all of them, loud enough to be heard in every bedroom over background noise with doors closed; wireless interconnected alarms satisfy this without physical wiring. Sec. 26-284(d) requires primary power from the building's commercial wiring with battery backup, prohibits a disconnecting switch other than normal overcurrent protection, and Sec. 26-284(f) caps a smoke alarm's service life at ten years from its manufacture date in one- and two-family dwellings, after which it must be replaced. Placement is also restricted near cooking appliances and bathrooms to cut false alarms, per Sec. 26-284(b)(4)-(5).
Violations & Fines
Missing, disconnected, or expired smoke alarms are a PMC violation the building official can cite during a Sec. 26-257 inspection; correction orders follow the same enforcement path as other PMC life-safety defects, through chapter 26, article XVI's administrative hearing process if the owner doesn't fix it.
