The 24-Hour List, in Plain Words

NSPIRE sorts every deficiency by how much harm it can do. The top tier is called life-threatening — and when an inspector cites one, the correction clock is 24 hours from notice, in every HUD program. Here is that list the way a super would say it:

Smoke alarm missing or not working. An alarm that isn't there, or doesn't sound when tested, in a unit or a required common-area spot.

Carbon monoxide alarm missing, blocked, or not working. Wherever a CO alarm is required — near fuel-burning appliances and fireplaces — it has to be installed, uncovered, and sound when tested.

Blocked exit. A door, hallway, fire escape, or bedroom rescue window blocked so people can't get out fast in a fire.

Exposed electrical conductors. Live wiring you can touch — open panels, missing covers on energized parts, dangling conductors.

Water touching electrical parts. A leak, standing water, or wet conditions in contact with wiring, outlets, or panels.

Gas or fuel leak — or a damaged, missing gas shutoff. Any smell-of-gas condition, a leaking fuel line, or a gas shutoff valve that is damaged, missing, or not installed.

No working heat in heating season. Between October 1 and March 31: the permanent heat source isn't working, or the unit is below 64°F inside.

Unvented fuel-burning space heater. A gas, oil, or kerosene space heater with no vent to the outside.

Blocked, disconnected, or failing flue or chimney. The exhaust path for a furnace or water heater blocked, misaligned, or missing — or a chimney damaged enough that it may not safely carry smoke and gases out.

Dryer exhaust detached, missing, or clogged. A dryer transition duct that's off or gone, or an exhaust run with restricted airflow.

Fire extinguisher missing, damaged, or out of date. Where extinguishers are provided: missing or damaged, the gauge reading over- or under-charged, or a service tag missing, unreadable, or expired.

Sprinkler heads blocked, painted, corroded, or damaged. Anything stored within 18 inches of a sprinkler head, or a head that can't spray the way it was built to.

A fire door that's gone entirely. A required fire-labeled door missing altogether is life-threatening; a fire door that won't close and latch is severe — and on the multifamily clock, also 24 hours.

Extremely heavy mold growth inside the unit. Mold-like growth at the highest level HUD's standard describes — not a spot on grout, a wall of it.

The unit's only toilet missing or not working. One toilet in the unit and it doesn't flush or can't be used — that's a 24-hour item.

This is the plain-words version of the most common life-threatening items — HUD's standards book is the complete, official list, with the exact definition of each deficiency. Read it at HUD's NSPIRE Standards page. And see Correction Timelines for what happens with the other severity levels.
