Subject: Carbon Monoxide Detectors in HUD-Assisted Housing
Purpose: The Offices issuing this notice are doing so to:
• Remind owners, managers, and agents of certain HUD-assisted housing to have
operational carbon monoxide (CO) detectors, where specified, as required by the state or
local law, code, or other regulation. The programs covered are the Public Housing,
Section 8 Project-Based Rental Assistance, Housing Choice Voucher (tenant-based or
project-based), Section 202 (Supportive Housing for the Elderly), Section 811
(Supportive Housing for Persons with Disabilities), and tribal programs administered by
the Office of Native American Programs (ONAP).
• Strongly encourage owners, managers, and agents of housing covered by the HUD
assistance programs above, located in areas where state or local law, code or other
regulations do not require CO detectors, to have operational CO detectors (1) in units that
have fuel-fired/burning appliance(s) and/or an attached garage, and (2) in bedrooms that
contain a fireplace or a fuel-fired or burning appliance.
Background: This notice is being issued as part of the Secretary’s efforts to support decent,
safe and sanitary housing in HUD’s low income housing assistance programs. CO poisoning is a
serious issue in housing across the nation. As the Environmental Protection Agency (EPA) notes:
Carbon monoxide is an odorless, colorless and toxic gas. Because it is impossible to
see, taste or smell the toxic fumes, CO can kill you before you are aware it is in your
home. The effects of CO exposure can vary greatly from person to person depending
on age, overall health and the concentration and length of exposure.1

Each year, there are over 11,000 CO exposure cases reported to poison control centers2 and
more than 400 deaths due to CO poisoning.3 CO death rates are highest for men, non-
Hispanic blacks, and the elderly.
Implementation: Because CO is undetectable through sight, smell, sound, or touch, a
device – a CO detector – is necessary to determine the presence of high and dangerous
concentrations of CO in a residence. The detectors are typically installed outside of
sleeping areas in units with fuel-fired/burning appliance(s), and/or an attached garage, and
installed in bedrooms that contain a fireplace or fuel-fired or burning appliance.
Often, a combination smoke detector–CO detector device can be used instead of installing
two devices; HUD encourages using combination detectors where they are not prohibited
by state or local requirements. Similarly, it is efficient to replace a smoke detector already
required to be in a unit covered by this notice 4 with a combination detector when the smoke
detector’s sensor dies, if this has not been done beforehand. Owners should also consider
installing a hard-wired detector with a battery backup even where it is not required by local
law.
On March 25, 2019, the Office of Public and Indian Housing’s Real Estate Assessment Center
(REAC) issued an Inspector Notice that establishes guidance to all UPCS inspectors who
conduct physical inspections of HUD-assisted and insured properties about performing a data
collection process to determine the prevalence of CO detection systems at HUD properties
subject to UPCS inspection.5 That REAC Notice also applies to HUD assisted and insured
properties subject to UPCS inspection, and other projects involving properties inspected under
the REAC physical inspection protocol.
Although not subject to UPCS inspection, HUD strongly encourages Indian tribes and tribally
designated housing entities (TDHE) receiving assistance under ONAP programs to include
functional CO detectors (either stand-alone or combination smoke detectors-CO detectors) as
part of their tribal housing quality standards, and to have their inspectors routinely check for
their prevalence and that the detectors are operational.
HUD anticipates issuing further guidance and instructions on this important public health
issue. In addition, HUD will pursue rulemaking for the Housing Choice Voucher, Multifamily
and Public Housing Programs to add a requirement for functioning carbon monoxide detectors
in units with fuel-fired/burning appliance(s), and/or an attached garage.

Housing Notice H 2019-05 (also issued as PIH 2019-06 and OLHCHH 2019-01) addresses carbon monoxide detector requirements in several HUD-assisted housing programs, including Public Housing, Section 8, Housing Choice Voucher, Section 202, Section 811, and tribal programs. Where state or local law already mandates CO detectors, covered properties are required to have operational devices in place. Where no such local mandate exists, the notice strongly encourages owners to install operational CO detectors in units with fuel-fired appliances or attached garages, and in bedrooms containing fireplaces or fuel-burning appliances.
Plain English — not legal advice.
Owners, managers, and agents of properties covered by Housing Notice H 2019-05 generally ensure that operational CO detectors are installed wherever state or local law requires them, and document compliance as part of routine property management. In jurisdictions without a local CO detector mandate, compliant operators typically install detectors proactively in units with fuel-fired appliances, attached garages, or bedrooms with fireplaces, consistent with the notice's strong encouragement. HUD also recommends considering combination smoke-CO detector devices and hard-wired units with battery backup, and notes that REAC inspectors conducting UPCS inspections will be collecting data on the prevalence of CO detection systems at covered properties.
General guidance for property managers — not legal advice for your specific situation. Consult an attorney for advice on your case.
Tenants living in HUD-assisted housing covered by Housing Notice H 2019-05—including Public Housing, Section 8, Housing Choice Voucher, and other listed programs—have an interest in knowing whether their unit contains an operational CO detector, particularly if it has fuel-fired appliances, an attached garage, or a bedroom fireplace. If a CO detector appears to be absent or non-functional in a covered unit, tenants may raise this concern with their property manager, contact the relevant HUD field office, or reach out to a local tenant-rights organization for guidance on available options. Tenants in tribal housing programs are also covered by this notice's encouragement that tribal housing quality standards include routine CO detector inspections.
General guidance for tenants — not legal advice for your specific situation. Consult a tenant-rights organization or attorney for advice on your case.
