Summary
Madison's Peter Talen Smoke Alarm Ordinance, MGO § 34.907, requires smoke alarms in every bedroom, sleeping area, and within six feet of each bedroom door, on every floor of nearly all residential buildings. Buildings from before 2009 follow this local rule; anything built after 2009 must instead meet IFC section 907.
(1)Smoke Alarms. Buildings built before 2009 shall comply with this section, all buildings built after 2009 shall comply with IFC section 907.(b)Required Installation.1.On August 15, 2009 all residential buildings, except owner-occupied single family homes, shall have smoke alarms in place which meet one of the following requirements:a.A smoke alarm with two (2) independent power sources consisting of a primary source that uses commercial light and power and a secondary source that consists of a non-rechargeable or rechargeable battery.b.A smoke alarm which is powered by a non-replaceable, non-removable battery that is capable of powering the smoke alarm for a minimum of ten years.2.On August 15, 2009 all owners of residential buildings, except owner-occupied single family homes, shall install and maintain a smoke alarm in each bedroom, in every sleeping area and within six (6) feet of each door leading to a bedroom or sleeping area of each unit and on each floor of the building.
Full Breakdown
Sec. 907, titled Fire Alarm and Detection Systems, splits coverage by construction date: buildings built before 2009 comply with the local ordinance, while buildings built after 2009 comply with IFC section 907 instead. For the older stock, as of August 15, 2009, every residential building except owner-occupied single-family homes had to have smoke alarms meeting one of two power standards, a unit with an independent commercial-power primary source plus a battery backup, or a sealed unit with a non-removable battery rated for at least ten years, installed in each bedroom, every sleeping area, within six feet of each door leading to a bedroom or sleeping area, and on each floor.
Owner-occupied single-family homes had until August 15, 2010 to comply with the same placement rules. Properties annexed from the Town of Madison on October 30, 2022 got their own compliance deadlines: multi-unit buildings by July 1, 2023, and owner-occupied single-family homes by December 31, 2023. Maintenance duties are split: owners must replace secondary-power batteries every lease renewal (or per manufacturer schedule, whichever is shorter) and swap out any alarm found inoperable within five days of written tenant notice, while tenants must test and maintain in-unit alarms and cannot tamper with, remove, or disable them.
No smoke alarm may stay in service more than ten years unless the manufacturer specifies otherwise, and owners and tenants must sign a compliance form at each new lease and at least annually thereafter.
Violations & Fines
Tampering with, removing, altering, damaging or otherwise rendering a smoke alarm inoperable violates Sec. 34.907(1)(c)5. Madison's rent-abatement schedule for housing-code violations (item 43, referencing § 34.907) treats a missing required alarm inside a bedroom or sleeping area as a 5-10% rent abatement per affected tenant, rising to 10-25% for a missing alarm within six feet of a bedroom door or on a required floor. Chapter 34's general penalty clause, Sec. 34.01(15)(a), separately backs the fire code with a forfeiture of $10 to $1,000 per day for violations not otherwise specified.
