Is that a Code violation? Should we think about constructing a
fireproof/fire-resistant barrier in the roof?

To provide a one-hour fire resistive seperation between the garage
and the dwelling, install drywall (5/8" type X) on the dividing wall
between the garage and house on the garage side extending up to the
roof sheathing, or drywall that same wall up and out on the ceiling
of the garage. Tape the joints.

Btw, openings between the garage and dwelling shall be provided with
a 1-3/8" solid wood or metal clad door installed with a self-closing
device. Openings in one-hour resistive ceilings are permitted if
protected by a UL listed fire door.

Careful, this thread has gone into areas of techincally
correct but unnecessary "requirements" in more than one
post. Best thing to do is get the answer from the
horse's mouth, and begin at the local Code Enforcement
Office. Some things will be grandfathered, some won't,
sometimes IF you work on it you have to upgrade and
maybe something else, or if you sell it then ... and on
and on and on, and I forgot the Homeowner's Insurance
get involved, too if it's not to code. Only your CEO
will know for sure or at least have access to be able
to know for sure.

Pop,

What do you think the "local Code Enforcement Office" uses to
administer and enforce the codes 'locally'? To mention a few, ever
heard of the Uniform Building Code, International Building Code,
International Residential Code?

Among others, I've got all of those code books sitting on my desk for
referral. They *are* the horses mouth and are all or in part adopted
by governmental agencys/building departments/code enforcement
departments nationwide with regards to building codes and their
enforcement of them.

When it comes to the "requirements and technicalities" regarding
housing, zoning, or public nuisance codes, as an ICBO, IBC, and CCEO
certified building, zoning, and code enforcement inspector I believe I
can give it from the horses mouth.

OTH if all I had to offer for advice was "maybe this or maybe that and
call your local inspector" then I would really have nothing to offer
here and I wouldn't.



Pop's statement was on the money.

Not really. Is he wrong to refer the OP to the locals? Of course not.
He should have done that and left it at that. I took his statement to
say that the rest of us were blowing hot air and the OP should just
contact the locals. Because he doesn't know beans about it doesn't mean
others don't. Hell, might as well just refer everyone whoever asks a
question in here to their locals, oh and google.

Different jurisdictions can, and often
will, alter the requirements of any national code to suit their
perceived needs.

You both seem to leave out one important element to that. If a
jurisdiction adopts a code they can alter it to make the code
requirements more stringent. Not less.

Your comment about a layer of 5/8" type X would not
meet the requirement for a one hour fire separation if I recall
correctly. I believe that at least two layers of 5/8" type X is required
to meet the one hour separation. I spent 33 years in the fire fighting
and fire protection field and I don't recall one layer meeting that
requirement. I could be wrong,...it's been a few years, and if I am, I
apologize.

You're talking apples and oranges. 5/8" type X gypsum drywall - of and
by itself has a rating of 40 minutes. IBC 720.2.1.4(2)

This thread refers to a *wall*. A wall comprised of different materials
that combined have a fire resistant 'period'. Granted, walls may be
constructed using different structural members but the *wall* and not
just one element are considered to determine the rating. There are of
course other methods or materials that can used to produce a one-hour
resistance rating. In residential WOOD-framed construction, 5/8 type X
over wood studs is pretty much the standard to meet the requirement. If
you have access to the International Building Code check the tables in
Chapter 7 - 719.1(2)-14 and the material ratings in

No appology necessary.
