Where does NSPIRE require smoke alarms?

Following the 2018 IRC placement requirements: inside every bedroom, outside each sleeping area (like a hallway serving bedrooms), and on every level of the unit including basements. Hallway-only coverage that passed HQS for years fails NSPIRE.

When are carbon monoxide alarms required under NSPIRE?

Per the 2018 IFC: when the unit has a fuel-burning appliance (gas furnace, gas range, gas water heater, fireplace) or an attached garage. All-electric units with no attached garage generally don't require CO alarms — but check state and local law, which can be stricter.

Are smoke alarm problems really a 24-hour fix?

Yes. Every smoke alarm and CO alarm deficiency in the published standards is classified life-threatening — missing, obstructed, or failing to sound when tested — which means a 24-hour correction clock once cited. At $15–40 per sealed 10-year alarm, this is the cheapest 24-hour risk you can eliminate in advance.

Smoke Alarms & CO Detectors Under NSPIRE

Every alarm deficiency in the standard is life-threatening — a 24-hour repair clock — and the placement rules are stricter than what passed HQS. This is the highest-stakes, cheapest-to-fix category in the entire inspection.

What inspectors actually check

Placement (2018 IRC)

Inside every bedroom, outside each sleeping area, every level including basements. The bedroom rule is the one older rentals miss — hallway-only coverage fails.

The test button

Inspectors press it. No audio or visual alarm = life-threatening citation, same as a missing alarm. Obstructed alarms (painted over, covered, blocked) are cited too.

CO alarms (2018 IFC)

Required with any fuel-burning appliance or an attached garage — proper location, working, unobstructed. All-electric with no garage? Generally not required federally; state law may differ.

The practical fix: sealed 10-year lithium alarms ($15–40 each) in every required location, dated photos of each one after install. No battery swaps for a decade, and your photo log answers any citation dispute.

Every citable alarm deficiency

Smoke and CO alarm standards — 6 citable deficiencies, 6 life-threatening. From the published HUD NSPIRE standards (v2026.07).
