Carbon Monoxide Detector Requirements for South Dakota Hotels and Short-Term Rentals
Spearfish deleted the carbon monoxide section. Its building code amendments at Section 150.016 item (4) read, in full, that IRC Chapter 3, Section 315 Carbon Monoxide alarms is hereby deleted, and that is the residential code rather than the one a hotel answers. South Dakota hotel carbon monoxide detector duties come from the state fire safety standards at ARSD 61:15:01:01, which adopt the 2015 International Fire Code, and ARSD 61:15:01:02 deletes Sections 102.5, 103 to 106.4 inclusive and 903.2.6 from it. Section 915 is not on that list, so a Spearfish hotel answers it regardless of what the city did to its residential code.

Key Takeaways
- The edition is the reason there is an answer at all. ARSD 61:15:01:01 adopts the 2015 editions of the International Building Code, Fire Code and Mechanical Code as the rules of the Department of Public Safety under SDCL 34-29B-2, and the 2015 International Fire Code is the edition that introduced Section 915.
- The state's deletions are a short list and easy to check against. ARSD 61:15:01:02 removes Sections 102.5, 103 to 106.4 inclusive and 903.2.6 from the 2015 fire code. Section 915 is absent from that list, and so is Section 1103.9 for existing buildings, so both apply as published.
- Spearfish is the only outright local deletion of a carbon monoxide requirement found in this survey. Section 150.016 item (4) removes the whole section rather than narrowing it, so the model code's trigger, its locations, its interconnection rule and its power source rule go with it.
- South Dakota caps its cities downward rather than upward. SDCL 11-10-12 lets a municipality adopt the 2024 International Residential Code and amend any provision of it at any time, then bars the governing body from requiring a residential sprinkler system or imposing any requirement more stringent than the 2024 IRC. The non-residential side at 11-10-5 is the permissive one: a local ordinance must comply with the 2024 International Building Code, and the governing body may amend, modify or delete any portion of it.
- Both of those sections exempt a specialty resort or vacation home establishment under chapter 34-18 that is built to Group R-3, which is the state writing its Black Hills lodging stock out of the local code question.
- Two local amendments predate the statute that now governs them. Box Elder's are Ordinance 642 of 14 February 2020 and Sioux Falls's amend the 2021 edition, while the ceiling in SDCL 11-10-12 arrived with SL 2022 chapter 35 and was last amended by SL 2026 chapter 59. Both look stricter than the model code the statute now makes the maximum. Neither question is resolved here, so ask the city whether it still enforces its version.
Legal Summary
South Dakota's lodging answer comes from the state fire safety standards. ARSD 61:15:01:01 provides that the standards of fire safety set forth in the International Building Code, International Fire Code and International Mechanical Code, all 2015 editions, "are the rules of the South Dakota Department of Public Safety authorized by SDCL 34-29B-2".
The edition matters more here than in most states. The 2015 International Fire Code is the edition that introduced Section 915, the carbon monoxide provision, so South Dakota's adoption reaches it rather than stopping at an earlier text that never had one.
The state took out a short list, which makes the position easy to check. ARSD 61:15:01:02 reads: "Sections 102.5, 103 to 106.4, inclusive, sections 903.2.6 are deleted from the International Fire Code, 2015 edition." Section 915 is not in it. Section 1103.9, the existing-buildings provision, is not in it either. Both apply as published.
From there the chain is the familiar one. Section 915 requires detection in Group I-1, I-2, I-4 and R occupancies, and IBC 310.2 places transient hotels and motels in Group R-1. An older property is reached through Section 1103.9 on the same conditions, so the duty does not wait for construction work.
Two features of the chapter confirm that lodging sits inside it rather than being argued into it. ARSD 61:15:01:17 writes exits for "new hotels, motels, multifamily residences which house six or more families, and congregate residences" in the chapter's own voice. And the local-variation rule, below, names the chapters a town may depart from and leaves chapter 9 out.
Who Is Covered
A transient hotel or motel is Group R-1 under IBC 310.2, which puts it inside Section 915 as adopted. Short-term rentals reach the same section through the Group R classification their occupancy supports, and the state's own record treats hotels and short-term lettings alike here.
South Dakota is one of the two states in this corpus where the lodging duty exists while the housing duty does not. The record answers no for private homes and no for long-term rentals, and yes for hotels. A private South Dakota house and a long-term rental carry no statewide carbon monoxide requirement; a guest room can. Wyoming is the other, and the cause is the same in both: the duty arrives through a fire code organised by occupancy rather than through a housing statute.
Coverage then turns on the conditions in Section 915 rather than on the building's name. Detection is required where a fuel-burning appliance or fireplace sits in the sleeping unit, where a fuel-burning forced-air furnace serves it, where such an appliance stands elsewhere in the building with a communicating opening to the unit, or where an attached private garage adjoins.
A property meeting none of those is outside the trigger rather than exempt from the code, and the difference shows up at the next renovation. An all-electric motel that adds a propane fireplace to a suite has moved that room into scope on the day the appliance is connected.
Hotels already standing: covered too. The South Dakota requirement reaches an existing hotel and not only one being built.
Operator Responsibilities
Confirm which edition the reviewing office is working from before anything else. South Dakota sits on the 2015 codes at state level, and a property in a municipality running a later edition may be reviewed against different section numbering for the same duty.
Audit each sleeping unit against the four Section 915 conditions and keep the reason beside the answer. The communicating-opening condition catches operators most often, because it turns on how the building connects rather than on what stands inside the guest room.
Treat the existing-building route as live. Section 1103.9 survived the state's deletions, so an older South Dakota hotel carries the requirement without any permit trigger. There is no construction-date cutoff to shelter behind.
Keep the deletion list itself in the compliance file. It runs to three items and it is the fastest way to answer a claim that South Dakota modified the carbon monoxide provisions: Sections 102.5, 103 to 106.4 inclusive, and 903.2.6. Anything else in the 2015 International Fire Code applies as published.
Installation and Technical Requirements
Because Section 915 was adopted without modification, the placement and device language is the model text of the 2015 International Fire Code. Detection belongs in the sleeping units, which for a hotel means the guest rooms rather than a corridor device covering a floor.
The 2015 edition is worth naming when ordering equipment or commissioning a design, since section numbering and some detail shifted in later editions. A specification written against a 2021 or 2024 text may reference provisions that do not exist in the code South Dakota adopted.
Smoke detection sits in the same chapter and is worth separating in the file rather than merging. ARSD 61:15:01:14 carries the smoke detector requirement for lodging establishments in the state's own words, with each sleeping room requiring detectors installed to the manufacturer's instructions. That is a separate duty from Section 915 and satisfying one is not evidence about the other.
A property already running a monitored fire alarm panel has the model code's detection-system route available as an alternative to individual alarms, which moves the compliance record from a box of receipts to a panel log.
Enforcement
The Department of Public Safety owns the standards, since ARSD 61:15:01:01 makes the adopted codes the rules of that department under SDCL 34-29B-2. Inspection and correction run through the state fire marshal's office and local fire officials in the ordinary way.
The provision an operator should read first is the local-variation rule, because it is unusually closed. ARSD 61:15:01:16 provides that "nothing in this chapter prohibits municipalities or local fire officials from adopting alternative requirements for International Fire Code, 2015 edition, chapters 20, 21, 24 to 27, inclusive, 29, 32, and 51, provided that the alternative requirement meets the intent and spirit of the code".
Read that as a closed list rather than as an example. Chapter 9 of the International Fire Code is where Section 915 lives, and chapter 9 is not on it. A South Dakota municipality therefore has no authority under this chapter to write an alternative to the carbon monoxide requirement, in either direction.
That is a stronger guarantee than most states give an operator. In much of the country the state text is a floor and the practical question is what the town added. In South Dakota the town has no room to move on this particular chapter, so a single state-level analysis holds across jurisdictions.
Penalties
No stand-alone statewide fine schedule for carbon monoxide detectors was established for South Dakota in the sources behind this page. Consequences run through fire code enforcement: inspection, written correction requirements, and the permit and occupancy machinery where construction work is involved.
One caution belongs with the penalties summary on this site. It rests on ARSD chapter 67:42, the child care facility rules, and concludes that no standalone fine table exists there. That is correct about chapter 67:42 and beside the point for a hotel, because the lodging duty comes from the fire safety standards in chapter 61:15:01 and not from the child care chapter at all. An operator should not read the child care chapter's silence as the state's silence.
Civil exposure is the larger risk and is unaffected by the absence of a fine table. A guest room meeting one of the Section 915 conditions with no detection is a departure from a code the state adopted in terms, and the adoption rule makes the standard easy to establish.
Where this answer runs out: SDCL 34-29B-2, the rulemaking grant behind the chapter, was not read verbatim, because the South Dakota Legislature serves its statutes through a JavaScript shell that returned no text. Its title is a general grant covering prevention, investigation, training and education, and the adopting rule carries no clause confining it to a class of property, but the statute's own penalty provisions were not reached. Reading SDCL chapter 34-29B end to end would settle it.
Local Override Warning
South Dakota's local layer is narrower than the usual formula suggests for a hotel, and the narrowness is written down. ARSD 61:15:01:16 lists the International Fire Code chapters a municipality or local fire official may adopt alternative requirements for: 20, 21, 24 to 27 inclusive, 29, 32 and 51. Chapter 9, which carries Section 915, is absent. For a hotel the local question is therefore which edition the town enforces for construction work and whether it has a building code of its own that changes numbering or review practice, rather than what the town added to the alarm rule.
A whole house let by the night is in a different world, and this is where the state gets interesting. That property is a residential structure under the International Residential Code, and SDCL 11-10-12 lets a municipality adopt the 2024 edition and amend any provision of it, while forbidding the governing body to require a sprinkler system in a residential structure or to impose any requirement more stringent than that edition. A South Dakota city may change its residential code freely in one direction only, and that direction is down. Both 11-10-5 and 11-10-6 then carve out something else a host should know: any specialty resort or vacation home establishment under chapter 34-18 built to Group R-3 is exempt from the local code question altogether, which is the legislature writing much of the Black Hills lodging stock out of it.
Spearfish is what that permission looks like when a city uses it. Its building code amendments at Section 150.016 item (4) read, in full: "IRC Chapter 3, Section 315 Carbon Monoxide alarms is hereby deleted." The whole section goes, and with it the model trigger, the locations, the interconnection rule and the power source rule. Nothing was narrowed and nothing was put in its place. This is the only outright local deletion of a carbon monoxide requirement found anywhere in this survey, and it lands in a Black Hills visitor town. The assumption underneath every national guide, that the model code sets a floor and local rules only build upward from it, does not hold in Spearfish. What it does not mean is that nothing applies there: state licensing of lodging, the fire code as it reaches buildings that are not residential structures, and any rental agreement all sit outside the residential code. It does mean that an owner in Spearfish cannot point at Section R315 and call it the local requirement. One wrinkle belongs to the city rather than to a reader: the ordinance deletes "Chapter 3, Section 315", and carbon monoxide alarms are R315 in the 2018 and 2021 editions while the 2024 edition renumbered them to R311 and gave R315 to sleeping lofts, so the same words remove the alarm rule under the older editions and the sleeping loft rule under the newer one. Ask Spearfish which edition it adopts.
Three other cities go the other way and two of them have a timing problem. Box Elder writes the tightest placement distance in this dataset: its amendment to Section R315.3 puts the alarm outside each separate sleeping area within five feet of the entrance, and within five feet of a future sleeping area as drawn on the approved plans, so an unfinished basement with a bedroom on the drawings gets its alarm at construction rather than when somebody frames the room. Section 6-240 rewrites R315.2.2 so that permitted alterations, repairs or additions over $5,000 in a dwelling unit bring interconnected alarms wherever fuel-burning appliances exist, and the companion smoke amendment at Section 6-239 defines immediate vicinity as an adjacent hallway or open space no more than ten feet from the bedroom door and within line of sight of it. Sioux Falls made one qualifier do the work. Its amendment to R315.2.2 triggers on permitted work valued over $1,000 and then exempts mechanical work only where it is "not fuel fired", so the exemption survives for the air conditioner and dies for the boiler, which is the distinction a carbon monoxide rule ought to draw and almost never does. Both ordinances predate the ceiling: Box Elder's is Ordinance 642 of 14 February 2020 and Sioux Falls amended the 2021 edition, while the cap in SDCL 11-10-12 arrived with SL 2022 chapter 35. Both look stricter than the model code the statute now makes the maximum. The tension is stated here and not resolved, so ask the city whether it still enforces the provision before relying on it.
Brookings avoids the problem by using a different instrument. Section 22-436 requires all registered rental units to carry carbon monoxide alarms, at a minimum outside each separate sleeping area in the immediate vicinity of the bedrooms, in dwelling units with fuel-fired appliances or attached garages, and adds one sentence putting a duty on the person in the room: the occupant shall not disable any required carbon monoxide alarm. That is a registered rental standard rather than an amendment to the residential code, so the cap in 11-10-12 does not reach it, and "at a minimum" leaves the city room to ask for more at inspection without amending anything. A host whose unit is on the Brookings register answers to it whatever the construction code says.
The negatives and the gaps, because a count settles nothing here. Nine municipalities were examined on 11 August 2026. Aberdeen and Sturgis carry nothing. Custer's single hit caps carbon monoxide at twenty-five parts per million at the property line in its industrial performance standards, and Custer answers twelve times for short-term rentals and never once for a detector. Deadwood and Pierre are not clean results at all: their Municode clients answer zero for every control including "building" and "fire", the unpublished-edition shape, and neither is on a second host. Rapid City, the second largest city in the state, is on none of the seven hosts this survey uses. Every other South Dakota municipality went unsearched.
