dwelling unit

[Rewire]

I have a detached garage that has an upper level being converted to a living area with bed and bath. We are on 05 and the inspector says it must be arc fault because it is a bedroom I say its not a dwelling unit (no cooking provision) he says it is being fed from a dwelling unit so it is "attached' am I going to lose ?

You called it a "bed" I think I would have to agree with the inspector
Around here, in a house, if it has a closet it's considered a bed room.

That's minor compaired to the fire ratings and such the GC might have to comply with.

The room over the garage does not fit the definition of dwelling unit. The room could be a family room with a bath, however you need to determine if it is worth the argument. If it were just bedrooms they were worried about then the NEC would require all hotel rooms to be AFCI.

Its not the hill i want to die on, what gets me is the inspectors determination of "attached" because it is being fed both plumbing and electrical from the house.

I would say that the detached garage and living space is accessory to a dwelling unit and therefore IMHO it would need to be AFCI protected.

Chris, this is your opinion, No? I believe it may be the intent but the words are not there to support your claim. Where is the words accessory building used in 210.12?

I find it odd that hotel and motel units, without cooking provisions, are not required to have AFCI

It is my opinion.

I agree that accessory building is not used in 210.12.

Here is my reasoning, The residential building code (IRC) regulates detached accessory structures that are accessory to a dwelling unit. That includes detached garages with living space. So my contention is that this detached accessory structure is an extension of the dwelling unit and therefore part of a dwelling unit.

Keep in mind that in Utah we must use the electrical portion of the IRC for single family dwelling units, and not the NEC.
