Summary

In the City of Lawrence, Section 704.6.1 of the amended property maintenance code requires existing Group I-1 and R occupancies, meaning most existing residential buildings, to have single-station smoke alarms installed under detailed placement rules, with an exception where fire alarm-connected detectors substitute for standalone alarms.

[F] 704.6.1. Where required. Existing Group I-1 and R occupancies shall be provided with single-station smoke alarms in accordance with sections 704.6.1.1 through 704.6.1.4. Interconnection and power sources shall be in accordance with sections 704.6.2 and 704.6.3. ... Exception: 1.Where smoke detectors connected to a fire alarm system have been installed as a substitute for smoke alarms.

Full Breakdown

Sections 9-730 through 9-736 rewrite the International Property Maintenance Code's smoke and carbon monoxide alarm rules for existing buildings in Lawrence. 3, except where smoke detectors connected to a fire alarm system have been installed as a substitute. 4, alarms must be at least three feet from a bathroom door or opening if that bathroom has a tub or shower. 2 requires interconnection so activation of one alarm triggers every alarm in the unit, audible in every bedroom over background noise with doors closed, though listed wireless alarms satisfy that requirement without physical wiring.

7 requires alarms to be tested and maintained per manufacturer's instructions and replaced once they stop functioning. Sections 9-735 and 9-736 extend the mandate to carbon monoxide alarms: any dwelling with a fuel-fired appliance or an attached garage that opens directly into the dwelling must have a carbon monoxide alarm outside each sleeping area, or inside a bedroom if a fuel-burning appliance sits within that bedroom or its attached bathroom, and a combination alarm may substitute for a standalone unit.

Violations & Fines

A failure to maintain required smoke or carbon monoxide alarms is enforced as a property maintenance code violation under Section 106.4: conviction carries a fine of $100.00 to $500.00, a jail term of five days to three months, or both, with each day the deficiency continues after notice a separate offense. The code official may instead pursue abatement under Section 106.5, ordering the owner to correct the deficiency.

Frequently Asked Questions

Does my older rental house in Lawrence need smoke alarms?
Yes. Section 704.6.1 requires existing Group I-1 and R occupancies, which includes existing residential buildings, to have single-station smoke alarms installed per the placement rules in Sections 704.6.1.1 through 704.6.1.4, unless smoke detectors wired to a fire alarm system are already installed as a substitute.
How close to my stove can a smoke alarm be installed?
It depends on the alarm type: ionization alarms need at least 20 feet of horizontal clearance from a permanently installed cooking appliance, or ten feet if the alarm has a silencing switch, while photoelectric alarms only need six feet, per Section 704.6.1.3.
Do I need a carbon monoxide alarm in my Lawrence house?
Yes, if the dwelling has a fuel-fired appliance or an attached garage that opens directly into the living space. Section 705.1 requires a carbon monoxide alarm outside each sleeping area under those conditions, and a combination smoke/CO alarm can satisfy the requirement.
Can I use wireless alarms instead of wiring them together?
Yes. Section 704.6.2 requires alarms to be interconnected so one activation triggers all of them, but it specifically says physical interconnection is not required where listed wireless alarms are installed and all alarms sound upon activation of one.
