I am wiring an addition on an existing house. Does the code require that I install hardwired smokes in the existing part of the house as well or just in the new addition? The existing part will not be remodeled. Also, what rooms require smokes? Bedrooms, kitchen, livingroom, office, laundry room, hallways.....anything else? What about a walk-in closet located within a master bath? Attached garage, or unfinished attic containing a furnace. Thanks for the information.

Absolute question for your building dept/Fire prevention. This is not covered by the NEC.

In Massachusetts, more than 30% of total sq' or addition of a bedroom. (+-)Entire dwelling must be brought up to code.

In Michigan,whenever there is a building permit,hard wired smokes are required.1 in every bedroom.And 1 in adjacent hallway.And 1 on every level of the house.We are allowed to use battery only smokes,in area's that are not being worked on,if damage must be done for installation.

This may be true. but check into when the house is sold.
This can also trigger an update to current requirements.

Merlin,
I'm from out of town, you could say.

Personally I would like to see smoke detectors in as many rooms as possible, all linked together, because you can't smell when you are asleep.
Having said that, installing a smoke detector in a kitchen is asking for trouble, if someone burns the toast, the whole house gets woken up.

Steam will also set off a smoke detector, because of the vapour, so it is best not to protect laundries with a dryer unless it is vented outside.

A note to installers of stand-alone smoke detectors, I have struck a few dodgy installs as a Fire Officer, by handymen that would negate their effectiveness.
There is a dead-air space that extends 1' from the corner of a ceiling, both horizontally out from a wall and vertically down that wall.
NEVER install a smoke detector in that space, in a fire, smoke never gets near this zone in the earlier stages.
In houses with a stairway, there should be a detector at the top ceiling above that stairway, in the centre of it, not off to one side or anything silly like that.


Let's face it, these days if you're not young, you're old - Red Green grin

We're talking MRC here . Most areas unless local ordance or Insurance company requires older houses not required to have them at all. Unless you can show me otherwise.

I believe you will be putting current code compliant smokes into any area that needs them and gets renovated on a permit in Florida.
I did it as a matter of course in my renovation and when my plan came back from plan review, that entry had a check mark next to it. They also put a check mark on my load calc.
I am not sure if either was really necessary but they did acknowledge it
I can ask the question over on IAEI if you like.
