Greetings,

I'm looking for some requirements for a detached garage. The rafter space is enclosed by a ceiling.

- Is ventilation required? As described in R806.1. There is none.
- Is access required? As described in R807. There is none.

Thanks,
Michael

Michael:

Because of the continuous roof over the main house and the garage this garage, at least for insurance purposes, is attached. Assuming though that you consider it a detached building due to the lack of contiguous walls, the answers are:

(1) Ventilation is required as per the code sited, but likely is required as well per the roof sheathing and shingle manufacturers. I am not aware of any exceptions regarding "detached" buildings. Some might argue that this is an "accessory structure", but it is not. That is defined as a structure that is incidental to that of the dwelling. Incidental is defined as something of minor consequence. Garages are not incidental structures.

(2) Access is required by the code stated.

Cited and not "sited" . . .

Have another coffee,

I would suspect that location would have much to do regarding attic ventilation?

As Aaron said: that garage is "attached".

Also, Yes. and Yes. to the ventilation and access questions.
