Alaska Carbon Monoxide Detector Law: Every Home

Q: Where does Alaska say the alarm goes?

The code prints the spot: installed and maintained according to manufacturers' recommendations. Alaska is one of 20 states that put a location in writing rather than leaving it to the manufacturer's instructions.

Q: What is the penalty in Alaska?

A violation, as that term is defined in AS 11.81.900. The code puts it this way: "(c) A person who violates AS 18.70.095 , as that section relates to carbon monoxide detection devices, is guilty of a violation. In this subsection, "violation" has the meaning given in AS 11.81.900 ."

The short answer

Alaska requires an alarm in every home, including one already lived in.

Alaska requires a carbon monoxide device in every qualifying dwelling unit in the state, meaning one with a combustion appliance, an attached garage or carport, or a parking space next to it, and the duty runs continuously rather than waiting on a sale, a permit or a new tenancy.

In Alaska the duty attaches to the dwelling itself, so it is on a house that was built, sold and lived in long before the section passed. The trigger the code names is none: the duty is continuous and applies to every qualifying dwelling unit in the state.

The section itself

Alaska Stat. 18.70.095(a), and what it attaches to

The sentence below is the whole of it. Everything that separates Alaska from the state across the river sits inside that sentence and inside the clause that conditions it, which is why it is reproduced rather than summarised.

A requirement and the event it waits for are two different facts, and a roundup that carries the first without the second is how the same state gets described as strict and as lax in the same week. Both are on the card, with the citation, the title the code gives the section and the link the sentence was read from.

The section

Smoke and carbon monoxide detection devices

Alaska Stat. 18.70.095(a)

(a) Smoke detection devices shall be installed and maintained in all dwelling units in the state, and carbon monoxide detection devices shall be installed and maintained in all qualifying dwelling units in the state. The smoke detection devices must be of a type and shall be installed in a manner approved by the state fire marshal. The carbon monoxide detection devices must have an alarm and shall be installed and maintained according to manufacturers' recommendations.

The section speaks to the dwelling rather than to something happening to it, which makes it the only shape that reaches a house nobody is building, selling or renting.

Why this state is unusual

Alaska is one of 10 states whose duty follows the dwelling

In the other 25 states that require an alarm, the requirement waits: for a sale, for a permit, for a first build, for a lease. A house standing in one of those states, owned by the same person for twenty years, can sit outside its state’s carbon monoxide section entirely. That is not true here.

Where the code says to put it

Alaska writes the location into the code

Alaska writes the spot into the code: installed and maintained according to manufacturers' recommendations.

The rule is quoted below in the code's own words. Nationally 20 states print one and 5 of those reach every storey rather than the sleeping floor alone, and no two of the 20 are quite the same sentence.

Where the code puts it

installed and maintained according to manufacturers' recommendations

The carbon monoxide detection devices must have an alarm and shall be installed and maintained according to manufacturers' recommendations.

In a rented home

What Alaska puts on a landlord and what it puts on a tenant

Alaska splits the job: the landlord puts the alarm in and the tenant keeps it working. The landlord provides working devices at each occupancy and repairs them once told, and the tenant keeps them working and does not disable them.

The split matters because the two halves are enforced differently: an installation duty runs against the owner and a maintenance duty commonly runs against whoever is living there. Where the section names no party, the card says so rather than filling the silence with the commonest answer. 28 states of the fifty reach a tenancy at all.

the landlord provides working devices at each occupancy and repairs them once told, and the tenant keeps them working and does not disable them.

(b) In a dwelling unit occupied under the terms of a rental agreement or under a month-to-month tenancy, (1) at the time of each occupancy, the landlord shall provide smoke detection devices and, if the dwelling unit is a qualifying dwelling unit, carbon monoxide detection devices; the devices must be in working condition, and, after notification of any deficiencies by the tenant, the landlord shall be responsible for repair or replacement; and (2) the tenant shall keep the devices in working condition by keeping charged batteries in battery-operated devices, if possible, by testing the devices periodically, if possible, and by refraining from permanently disabling the devices.

What counts as an alarm

Alaska names no alarm standard in the section

Alaska names no alarm standard in the section, which leaves approval to the code the building is inspected under.

38 states of the fifty name a standard and 16 say in writing that a combination smoke and carbon monoxide alarm satisfies the requirement. Where a state named none, approval belongs to the code the building is inspected under, which is a local reading rather than a state one.

What the code provides

Alaska writes the consequence into the section

Alaska writes the consequence into the code: a violation, as that term is defined in AS 11.81.900.

It is quoted on the card above in the sentence it was read from. What a penalty clause says and what an enforcement body does with it are different questions, and only the first is on this page. Nationally 19 states print something inside the section; the rest send a reader to a general enforcement provision.

How Alaska compares

The same question in the other forty nine

42 states require a carbon monoxide alarm in a home and 8 have no statewide section for one. Of the 42, 10 reach a home already lived in, 25 wait for a sale, a permit or a first build, and 28 reach a rented home.

The bar splits the fifty by what their section touches, and the table beneath it puts them in alphabetical order for finding a particular one. Neither order tracks how cold a state gets.

Ohio is one of ten states whose carbon monoxide section attaches to the dwelling itself, so it reaches these houses as they stand. In most of the country the same section would wait for one of them to be sold, altered under permit or rebuilt. “Queen City Avenue, South Fairmount, Cincinnati, OH (28224745388)”, Warren LeMay, CC0

Alaska carbon monoxide alarm questions

Does Alaska require a carbon monoxide detector?

Does the Alaska requirement apply to an older house?

Yes. Alaska is one of ten states whose section speaks to the dwelling rather than to a sale, a permit or a new build, so the age of the house does not change the answer. The section reads: "(a) Smoke detection devices shall be installed and maintained in all dwelling units in the state, and carbon monoxide detection devices shall be installed and maintained in all qualifying dwelling units in the state. The smoke detection devices must be of a type and shall be installed in a manner approved by the state fire marshal. The carbon monoxide detection devices must have an alarm and shall be installed and maintained according to manufacturers' recommendations."
