Summary
Story County doesn't mandate carbon monoxide detectors in homes, but County Code Section 64.07(1) requires any aquatic facility, such as a public pool, spa or waterslide, with fuel-burning appliances to install UL 2075-listed detectors with local alarms in the appliance room and every adjacent room, replaced at least every two years.
64.07 FACILITY REQUIREMENTS. 1. CARBON MONOXIDE DETECTORS. An aquatic facility utilizing fuel burning appliances shall have carbon monoxide detectors with local alarming, certified, listed, and labeled in accordance with UL 2075, in the room with the appliance and all rooms that are immediately adjacent to the space containing fuel burning appliances or vents carrying the products of combustion. Date of installation shall be labeled and visible without removal of detector. Carbon monoxide detector shall be replaced every 2 years or before if required by manufacturer's recommendations.
Full Breakdown
Chapter 64 regulates aquatic facilities in Story County under authority the Board of Health adopted alongside Iowa Administrative Code 641-15, Swimming Pools and Spas. 07(1) sets the county's only carbon monoxide detector mandate: an aquatic facility that uses fuel-burning appliances, water heaters or boilers for example, must install carbon monoxide detectors with local alarming in the room housing the appliance and in every room immediately adjacent to it or to any vent carrying the appliance's combustion products. The detectors must be UL 2075-certified, listed, and labeled, and the installation date must be labeled on the device and visible without removing it, so an inspector can confirm it is current.
The code also sets a replacement clock: detectors must be swapped out every two years, or sooner if the manufacturer's instructions call for it. This requirement sits inside the facility-requirements section of the aquatic facility chapter, which also covers matters such as designating a contact person for the Inspection Agency and posted signage. 07(1) applies specifically to aquatic facilities with fuel-burning appliances, and residential CO alarm rules elsewhere in Iowa run through the fire and building codes adopted at the city or state level, not through this county health chapter.
Violations & Fines
Aquatic facility inspections are carried out by the Inspection Agency designated under Iowa Code Chapters 28E and 1351 (Section 64.04). A violation found during an inspection, including a missing or non-compliant carbon monoxide detector, triggers a written Corrective Action Plan under Section 64.06(5) listing the remediation steps and a completion date. Repeated violations or an uncorrected imminent health hazard can be logged as a serious deficiency under Section 64.06(10), bringing closer scrutiny from the Inspection Agency.
