HUD Smoke Alarm and Carbon Monoxide Alarm Requirements for Section 8 Landlords (HQS and NSPIRE)

Smoke and carbon monoxide (CO) alarm problems can fail a voucher unit fast. Under NSPIRE, a missing, blocked or dead alarm is a life-threatening deficiency with a 24-hour fix window. This guide covers the federal alarm rules for Housing Choice Voucher (Section 8) units in the Dayton area: where alarms go, what changed in December 2024, and what to check before the inspector arrives.

It is written by ATK Inspections, an independent HQS/NSPIRE inspector in Dayton. We are not a housing authority or HUD. Your housing agency (PHA) makes the official call on your unit.

Which rules apply right now

Voucher programs are moving from Housing Quality Standards (HQS) to NSPIRE. Under HUD Notice PIH 2026-18 (issued July 15, 2026), PHAs may keep using “HQS as previously defined” until February 1, 2027, the NSPIRE compliance date for the HCV, PBV and Mod Rehab programs. HUD encourages PHAs to switch sooner.

The alarm rules don't wait for that date. PIH 2026-18 says that whether a PHA has implemented NSPIRE or still uses HQS, it must comply with all carbon monoxide and smoke alarm requirements. HUD also points out that forms HUD-52580 and HUD-52580-A don't include the current alarm requirements, so PHAs still using those forms have to add them to their inspections. Ask your PHA which standard and which alarm protocol it uses for your unit.

Smoke alarms under HQS (as previously defined)

The HQS rule at 24 CFR 982.401(n) requires:

At least one battery-operated or hard-wired smoke detector, in proper operating condition, on each level of the unit, including basements but not crawl spaces or unfinished attics.
Installation in line with NFPA 74 or its successor standards (HUD now points to NFPA 72).
If a hearing-impaired person lives in the unit, smoke detectors with an alarm system designed for hearing-impaired persons.

Smoke alarms under NSPIRE

HUD's NSPIRE Smoke Alarm standard (V3.0, published 08/11/23) asks for more locations. The unit needs at least one battery-operated or hard-wired smoke detector, in proper working condition:

On each level of the unit.
Inside each bedroom.
Within 21 feet of any door to a bedroom, measured along a path of travel.
On the living-area side of a door, when a detector outside a bedroom is separated from an adjacent living area by that door.

The standard's placement guidance:

Mount high on a wall or ceiling. On a ceiling, keep it more than 4 inches from the wall. On a wall, the top edge should be no closer than 4 inches and no farther than 12 inches from the ceiling.
Keep it at least 10 feet from a cooking appliance.
Keep it away from windows, doors or ducts where drafts might interfere.
Don't paint it or put stickers or decorations on it.

NSPIRE lists three smoke alarm deficiencies: not installed where required, obstructed (covered by something like a plastic bag, shower cap, zip tie, paint or tape), and no audio or visual alarm when tested. The inspector presses the test button. If there is no test button, the inspector asks for a smoke alarm maintenance certificate. A combination smoke/CO alarm is checked under both standards.

The hardwired or sealed 10-year battery rule

PIH 2026-18 reminds PHAs that they must comply with the Federal Fire Safety Act of 1992 and keep smoke alarm standards current with NFPA 72. It adds that changes from the Consolidated Appropriations Act, 2023 took effect on December 29, 2024, requiring smoke alarms to be either hardwired or sealed, 10-year battery devices. HUD says NSPIRE will be updated to reflect these mandates. PHAs still on HQS may keep their own protocols as long as they fully comply with all smoke alarm requirements.

In practice, a basic alarm with a replaceable battery is the one to look at first. Ask your PHA how it is checking for this requirement on your inspections.

Carbon monoxide alarms

Section 101 of Division Q of the Consolidated Appropriations Act, 2021 requires CO alarms or detectors in HUD-assisted housing, including HCV and PBV units, installed in a way that meets or exceeds Chapters 9 and 11 of the 2018 International Fire Code (IFC). HUD Notice PIH 2022-01 told PHAs and owners that HUD would enforce the requirement, which applies to housing with fuel-burning appliances or an attached garage. Per PIH 2026-18, it took effect and became an inspectable item on December 27, 2022.

HUD's NSPIRE Carbon Monoxide Alarm standard (V3.0, 08/11/23) treats a CO alarm as missing or misplaced in any of these situations:

Fuel-burning appliance or fireplace in the unit: no CO alarm in the immediate vicinity of each bedroom or inside each bedroom.
Fuel-burning appliance or fireplace in a bedroom or its attached bathroom, or adjacent spaces that combustion gases can flow from: no CO alarm in each bedroom.
Forced-air furnace located elsewhere serving the unit: no CO alarm near or inside each bedroom, or in the room with the first duct register (with signals sent to an approved location).
Fuel-burning appliance or fireplace elsewhere in the building: no CO alarm in an approved location between it and the unit, or on the ceiling of the room that contains it, or near or inside the bedrooms when there are communicating openings.
Attached private garage one story or less above or below the unit or bedroom, with no natural ventilation or (if enclosed) no vehicle exhaust ventilation: no CO alarm near or inside each bedroom.

A CO alarm that is obstructed, or that doesn't alarm when tested, is also a deficiency. If a fuel-burning appliance is in an attic, the standard treats the attic as a mechanical room. NSPIRE also notes that its inspection is not a replacement for a code inspection and that all IFC Section 915 and 1103 requirements still apply.

Why alarm problems fail fast

Every smoke alarm and CO alarm deficiency in the NSPIRE standards is rated Life-Threatening, with a 24-hour correction timeframe and an HCV Fail. Under PIH 2026-18, life-threatening deficiencies must be corrected within 24 hours after the owner is notified of the results. If a deficiency isn't corrected in time, the PHA must start HAP contract enforcement, which can include withholding or abatement of assistance payments.

Landlord alarm checklist before the inspection

☐ A working smoke alarm on every level, including the basement.
☐ A smoke alarm inside each bedroom and within 21 feet (path of travel) of every bedroom door.
☐ An extra smoke alarm on the living-area side of any door that separates the hallway alarm from a living area.
☐ Alarms mounted high, at least 10 feet from the range, away from drafts, and not painted, stickered or covered.
☐ Smoke alarms that are hardwired or sealed 10-year battery units.
☐ Every alarm tested with its test button. Keep a maintenance certificate for any alarm without one.
☐ A list of every fuel-burning appliance and fireplace in the unit and building, and whether there is an attached garage.
☐ CO alarms placed to match each NSPIRE situation above, tested and unobstructed.
☐ Your PHA's answer on which standard (HQS or NSPIRE) and which alarm protocol it uses.

Frequently asked questions

Do smoke and CO alarm rules apply if my PHA still uses HQS?

Yes. HUD Notice PIH 2026-18 says PHAs must comply with all carbon monoxide and smoke alarm requirements whether they have implemented NSPIRE or still use HQS as previously defined.

Does NSPIRE require a smoke alarm in every bedroom?

Yes. HUD's NSPIRE Smoke Alarm standard lists inside each bedroom, on each level, and within 21 feet of any bedroom door as required locations.

When is a carbon monoxide alarm required?

When the unit or building has a fuel-burning appliance or fireplace, is served by a forced-air furnace located elsewhere, or sits one story or less from an attached private garage without the ventilation described in the standard. Locations depend on the situation.

How fast do I have to fix an alarm deficiency?

NSPIRE rates smoke and CO alarm deficiencies as life-threatening, and PIH 2026-18 requires life-threatening deficiencies to be corrected within 24 hours after the owner is notified.

Do I still need to check local codes?

Yes. HUD's CO standard says the NSPIRE inspection isn't a replacement for a code inspection. Check with your city or county for any local requirements.
