The type of home is elevated construction where there is a stairway leading up to the next level. The only exception I was able to find was in the Florida Building Code dealing with split level construction.
Cannot speak to florida
Used to be a smoke alarm was required at the top of the stairs.
Under the IRC code it is now 1. in each bedroom, 2. outside a bedroom or before the first one, 3. on each level.
This is the 2010 Florida code, Not sure what was adopted in 2014, but more than likley read the same.
Sorry cannot cut and paste.
Look at section 314.3::: basicaly says what I said above You can always add more!!
That is the way I read it also
Each sleeping area and outside each sleeping area and on every level of the home
I was at a property the other day and the builder was present, I stated there should be a smoke alarm device on every level of the home and there was not one located on the first level. His response was the house was just constructed and the city building inspector passed the home and did not mention the lack of a smoke alarm there.
Which makes me think there maybe an exception somewhere but the only thino I can find is the split level exception in which this would not apply.
Had a wise Inspector tell me::
"""" if you do not know the code, you cannot enforce it """"
Sad that this simple and been around for awhile item was missed. BY ALL from designer, to builder, to electrician, to inspector.
But you caught it!!!
Unless the split-level exception is met, there should be one on each level. Top of the stairs is usually used since smoke rises with the heat...so top of basement stairs or top of entry stairs (I assume "elevated construction" means one of those houses built a story above the ground). But any logical spot based on path of smoke travel and before occupants would be blocked from escaping can work too.
Rule of thumb: just because an inspector doesn't catch it, doesn't mean it is not required. Did the inspector's boss, the Certified Building Official (the only one who has any authority on accepting exceptions), provide a signed letter of exception on jurisdiction letterhead for this? With a logical explanation of why one less detector is sensible in this case (which can be possible based on individual circumstances)? If not, then it is still required, at a minimum.
Requirements for smoke detection depend on the adopted codes and standards in the jurisdiction where the home is located. As the question was posted to a NFPA site I will assume your locale has adopted NFPA. This being said the NFPA requires the following for smoke detectors:
Where required by other governing laws, codes or standards for a specific type of occupancy, approved single-station smoke and multiple-station smoke alarms shall be installed as follows:
1) In all sleeping rooms and guest rooms.
2) Outside of each separate dwelling unit sleeping room, within 21 feet of any door to a sleeping room, with the distance measured along a path of travel.
3) On every level of a dwelling unit, including basements.
4) On every level of a residential board and care occupancy (small facility), including basements and excluding crawl spaces and unfinished attics.
5) In the living area(s) of a guest suite.
6) In the living areas of a residential board and care occupancy (small facility). [72:22.214.171.124*]
Hope this helps. Just my opinion,
