Reading the actual guideline text below — never a general AI guess

I need to be direct with you: the passages shown here don't actually address carbon monoxide detectors in garages. The first source listed is "Carbon Monoxide Detector Requirements," but the excerpt from that document was withheld due to fair-use limits, so we can't tell you what it says. The other passages cover garage door safety, fire separation in converted garages, solar systems, smoke detectors in sleeping areas, and how appraisers classify detached garages—but none of them discuss carbon monoxide detectors specifically.

To get a straight answer on this question, you'd need to see the full text of the Nevada adopted IRC R315 carbon monoxide requirements.

Straight from Carbon Monoxide Detector Requirements (IRC R315), Garage Door Auto-Reverse Safety, Garage Conversions & Attic Stairs, HUD/FHA Single Family Handbook 4000.1, and UAD 3.6 / URAR — nothing added.

UAD 3.6 adoption and FHA guidance on garage conversions

FHA HB 4000.1 (pages 499–500) provides current guidance on treatment of garage conversions in appraisals, with criteria for counting converted space as GLA that do not explicitly require permits—relevant to understanding when to include or exclude unpermitted conversions.

Texas Smoke Detector Requirement for New Construction and Property Transfers

Texas law requires that one- or two-family dwellings with construction commenced after January 1, 2008 must have a working smoke detector, and properties constructed before that date must have one installed before sale or transfer of ownership.
