Besides for the code specified locations for UL rated fan boxes in a ceiling ie. bedrooms, kitchens, yada yada. Is it permisable to use 1900 boxes in the remainder of the locations ie. hallways, and closets?

Re: Ceiling boxes
Yes, as a rule of thumb, wherever a fan won't fit you can use a regular box.
Do you have a local code that requires fan boxes?
I'm not aware of an NEC requirement but I still think it's a good idea to install fan boxes in all locations but closets and hallways.

Re: Ceiling boxes
And if the fan is heaver than 70# we are not allowed to use a box as support. See 422.18(B) and the exception.
The NEC only requires a fan rated box where a fan is directly supported from the box. "Sole Support"
We don't use the box as the sole means of support as we run long screws into the truss or made structural member behind the box.

Re: Ceiling boxes
You don't have to use fan boxes anywhere unless you are planning to install a fan.

Re: Ceiling boxes
I know of inspectors that enforce this non-existant rule.
Yes, I know that. I was talking about a requirement to install them in places that a fan is likely to be installed, like a bedroom. As Scott said, that requirement doesn't exsist.

Re: Ceiling boxes
Just to add, I usually install fan boxes
anyway because everybody knows what happens when you don't. However as pointed out the NEC does not mandate them unless a fan is going in.

Re: Ceiling boxes
Take a look at them plastic L shaped ones.The fan will be held by 2 screws into the truss or wood holding the box.Fast ,cheap and complies to code.Rather spend the money where there is any chance of a heavy light or a fan.Changing them out later is rough.

Jim those fan master boxes have draw backs when used for luminare installations,First is the mounting bar for regular fixtures are sized for an 8/32 and those boxes come with a 2 in. #10.Also is there is no room for a fixture nipple.The box mounting hole is dead center of the box and flush with the bracket mounting holes.We use common plastic boxes for the tract homes and the higher end homes get 1 1/2 deep octagon.Unless it is a really obvious that a really heavy fixture will be installed then we use the octagon with a 2x12 above it and all thread with fender washers that extend through the box,these support the fixture

Re: Ceiling boxes
wow...i know nec does not require them..but I assumed that other city's did, it's like old hat in Chicago. We are required under CEC to install UL rated fan boxes everywhere, except baths, hallways, and closets. Dosen't matter what you're hanging on em.

Re: Ceiling boxes
I would check local and state codes and see if they say which or where fan rated boxes need to be.
The Wisconsin state electrical code supercedes NEC and requires all ceiling boxes for luminaires in habitable rooms to be fan rated.
For smoke detector devices, you could use a standard ceiling box, or even a single gang plastic rough box (smoke detectors are considered devices).
Closets you can't install a paddle fan.
Hallways, foyers and stairways... check local and state codes again.
