The following is a reminder on Texas HB 1168, which places statewide requirements on landlords of all types of dwellings by January 1, 2013:

• State of Texas: Gov. Rick Perry signed HB 1168 in June 2011. The act establishes requirements for smoke alarms in residential rental units. The bill became effective on September 1, 2011, and applies to residential units occupied or issued a certificate of occupancy issued before this date. Landlords would be required to comply with the changes in the Property Code by January 1, 2013. Some more specifics on the law below.

• Smoke alarms are required to be placed in:

• Every bedroom for a property that holds three or more dwelling units

• Every hallway serving multiple bedrooms and

• Every level of the dwelling unit.

• Smoke alarms are to be battery powered unless another power source was required by local ordinance. A local ordinance could not require property owners to install a hardwired smoke alarm system for a unit that was in compliance with the fire code and built before September 1, 1987, unless:

• The interior of the unit experienced repairs, renovations, or additions that totaled more than $5,000,

• The building alterations required a municipal building permit, and

• Either the renovations resulted in the removal of an interior wall/ceiling or the unit had an alternative access for easy installation (e.g. a crawl space or tiled ceiling).

• The landlord is responsible for initial installation and/or replacement of smoke alarms in these dwelling units defined by HB 1168. The tenant is obligated to inform their landlord if a smoke alarm is in need of replacement and must replace batteries as needed for a unit that was installed in “good working order” at the time the tenant took possession.

NOW IN EFFECT: An amendment to the Houston City Fire Code (Ord. No. 2015-1289) requires that single-station battery-operated smoke alarms be replaced with 10-year battery alarms upon their expiration. The law affects institutional and residential properties.

A bill requiring 10-year smoke alarms in select dwellings has been reintroduced in the State of Washington's House of Representatives. House Bill 2053 would amend the Residential Code of Washington to require newly installed smoke alarms to feature a tamper-resistant, 10-year lithium battery. This provision would apply to homes occupied by persons other than the owner on or after December 31, 1981, and homes built or manufactured after December 31, 1980. The owner or landlord is not required to install a 10-year alarm if the dwelling unit is equipped with a hardwired smoke alarm with battery back-up or a combination smoke and carbon monoxide alarm. Penalty for non-compliance of this bill is subjected to fines upwards of $200.

A new bill (HB 2401) was introduced to the Committee on Local Government on January 16, 2014. Beginning July 1, 2016, all battery-powered smoke alarms must contain a non-replaceable, non-removable battery capable of powering the alarm for a minimum of 10 years. All alarms must also provide a display of the manufacture, date of installation and a hush feature. Exemptions include: control unit, enhanced waking effectiveness, multi-sensing technologies and wireless inter-connection.


In accordance with Madison Ordinance, all rental units are to have smoke alarms installed and maintained in each bedroom, in every sleeping area, and within 6 feet of each door leading to a bedroom or sleeping area, and on each floor of the building.
