Carbon Monoxide Detector Requirements for Arkansas Hotels and Short-Term Rentals

Arkansas does not have a standalone statute requiring carbon monoxide alarms in hotels. An earlier residential CO requirement, Arkansas Code § 20-7-138, was repealed by Act 2013, No. 565, effective August 16, 2013. Carbon monoxide detection requirements for hotels and motels now flow exclusively through the Arkansas Fire Prevention Code (AFPC), a three-volume code set adopted and enforced statewide by the Arkansas State Fire Marshal's Office. The AFPC Volume II incorporates the 2021 International Building Code (IBC 2021), which mandates CO detection under Section 915 in Group R-1 occupancies, including hotels and motels, when sleeping units contain a fuel-burning appliance, are served by a fuel-burning forced-air furnace, or are contiguous to an attached private garage. The AFPC applies statewide, including in rural and unincorporated areas where no local building department exists. Residential properties used as short-term rentals are covered by AFPC Volume III, based on the 2021 International Residential Code.

Hotels, motels and other Group R-1 transient occupancies are covered under AFPC Volume II (IBC 2021 §915) when sleeping units contain, are served by, or sit in a building containing a carbon monoxide source. An all-electric hotel with no fuel-burning equipment anywhere in the building and no attached garage falls outside the trigger entirely. Short-term rental operators letting residential-type dwellings answer AFPC Volume III instead, based on the 2021 International Residential Code, whose Section R315 requires alarms in new and altered dwellings with a fuel-burning appliance or an attached garage.

The statewide baseline is a floor rather than a ceiling. Section 101.2.2 confines a local jurisdiction to adopting and enforcing the AFPC and makes the code the only foundation document a city may modify "should they choose to adopt more stringent provisions", so an Arkansas city can require more than Section 915 does provided it builds on the code. Every operator therefore starts from the same statewide text and still has one local document to check.

Section 915.1 of Volume II decides which guest rooms are caught, and it asks four separate questions. A unit holding a fuel-burning appliance or fireplace is caught by 915.1.2. A unit served by a fuel-burning forced-air furnace is caught by 915.1.3, unless a detector sits in the first room or area served by each main duct leaving the furnace and its signal is transmitted automatically to an approved location. A unit merely sitting in a building that contains fuel-burning equipment is caught by 915.1.4, unless there is no communicating opening or a detector is placed between the equipment and the unit or on the ceiling of the room holding it. A unit in a building with an attached private garage is caught by 915.1.5, unless it is more than one storey above or below the garage, has no communicating opening, or reaches the garage only through an open-ended corridor.

CO alarms must be listed under UL 2034. Where CO detection systems are installed, detectors must be listed under UL 2075. Combination CO/smoke alarms are permitted when listed under both UL 217 and UL 2034. Under IBC 2021 §915.4, alarms must receive primary power from building wiring where commercial power is available, with battery backup when primary power is interrupted. Hardwired connection is required with no disconnecting switch other than overcurrent protection. Activation must annunciate at the building alarm control unit and initiate audible and visible alarm notification per NFPA 72.

STR operators offering residential properties are responsible under AFPC Volume III (IRC 2021) for providing CO alarms in qualifying new construction. Operators bear responsibility for both initial installation and for ensuring detectors remain in operational condition throughout each tenancy.

An operator running a hotel that was built years ago should not stop at Volume II, because it answers only part of the question and the fire code answers the rest. Volume I Section 915.1 provides that carbon monoxide detection "shall be installed in existing buildings in accordance with Section 1103.9", and 1103.9 requires it in existing Group I-1, I-2, I-4 and R occupancies on the same conditions Section 915 sets for new work. Section 102.1 applies the construction and design provisions to existing structures "where required in Chapter 11", so the duty does not wait for a permit to be pulled. In practice that turns a retrofit into three decisions rather than one: which rooms meet a trigger, whether battery-only alarms are permitted because the code in force when the building went up required none, and whether a detection system under Section 915.5 is cheaper to run across the property than devices room by room.

A guest room is a sleeping unit, so Section 915.2.2 governs and it is short: carbon monoxide detection is installed in sleeping units. The one exception permits the device outside each separate sleeping area, in the immediate vicinity of the unit, and it opens only where both of two things hold. The unit or its attached bathroom must contain no fuel-burning appliance, and the unit must not be served by a forced-air furnace. A room on a fuel-fired forced-air system fails the second half, so it keeps its detector inside the room even though nothing burns in the room itself. The sentence next to it, Section 915.2.1, places the device outside each separate sleeping area in the immediate vicinity of the bedrooms, and that is the rule for dwelling units rather than for a guest room.

Two things the Arkansas code does not say, both of which this page used to. There is no Section 915.2.6: Section 915.2 runs 915.2.1 to 915.2.3 in Volume I and Volume II alike. And ceiling mounting is not a requirement. It appears once in Section 915, as the second exception to Section 915.1.4, where a detector on the ceiling of the room holding the fuel-burning appliance is one way to avoid putting devices in the units that appliance serves.

Device rules: alarms listed to UL 2034, combination carbon monoxide and smoke alarms to UL 217 and UL 2034, and where a detection system is used instead its detectors are listed to UL 2075 and combination detectors to UL 268 and UL 2075. Primary power comes from the building wiring where that wiring is served from a commercial source, with battery power on interruption and no disconnecting switch other than overcurrent protection.

The Arkansas State Fire Marshal's Office enforces the Arkansas Fire Prevention Code statewide, including in rural and unincorporated areas where no local authority having jurisdiction exists. Local building departments enforce the code within their corporate limits where a building department has been established. Under Section 101.2.2 a local jurisdiction adopts and enforces the AFPC and nothing founded on another document, and the same section leaves it free to adopt more stringent provisions on that foundation, with the State Fire Marshal advising it of anything that falls below the code. The practical effect for a hotel is one uniform floor everywhere in Arkansas and one local document that can raise it.

Arkansas has no standalone hotel CO penalty statute, and it does not need one, because the code carries its own. AFPC Volume I Section 112.4 makes a person who violates a provision of the code guilty of a Class A misdemeanor punishable by a fine of not more than $1,000 or imprisonment not exceeding one year, or both, and each day the violation continues after due notice has been served is a separate offense. That per-day clause is the part worth planning around on a property with many rooms, since the count runs from the date of notice rather than from the inspection. The building code half is quieter: Volume II Section 114.4 says only that a violator "shall be subject to penalties as prescribed by law" and names no figure of its own. Correction orders, stop-work orders and a withheld certificate of occupancy run alongside all of this, and for a hotel mid-refurbishment they usually bite harder than the fine does.
