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.

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.

Frequently Asked Questions

Where does Lafayette require smoke alarms in a home?
Sec. 26-284(b)(2) requires them in each sleeping area, in every room along the escape path from a bedroom to the unit's exit door, and on every story of the dwelling, including basements; split-level units get an exception letting one upper-level alarm cover the adjacent lower level if it's less than a full story below.
Do Lafayette's smoke alarms have to be interconnected?
Yes, when more than one is required in a unit. Sec. 26-284(c) requires them wired or wirelessly linked so that activating one alarm sounds all of them, audibly, in every bedroom with the doors closed.
How long can a smoke alarm stay in service in Lafayette?
Sec. 26-284(f) requires alarms in one- and two-family dwellings to be replaced no more than ten years from the manufacture date marked on the unit, or replaced outright if that date can't be determined.
