One sheet rock contractor replacing the sheet rock in a Houston garage that was flooded by Harvey
says there are two sizes, one thicker than the other. Another sheet rock contractor working inside
the house says just use the standard size. Is there a thicker size that should be used in a garage?

After Googling the subject, looks like we should be using Type X which is 5/8 inch compared to the
standard which is 1/2 inch. It is also more fire resistant

Typically you use what code calls for
The 2006 edition of the IRC states the following concerning garage walls
and ceilings:

R309.2 Separation Required
The garage shall be separated from the residence and its attic area by
not less than 1/2-inch (12.7 mm) gypsum board applied to the garage
side. Garages beneath habitable rooms shall be separated from all
habitable rooms above by not less than 5/8-inch (15.9 mm) Type X gypsum
board or equivalent. Where the separation is a floor-ceiling assembly,
the structure supporting the separation shall also be protected by not
less than 1/2-inch (12.7 mm) gypsum board or equivalent. Garages located
less than 3 feet (914 mm) from a dwelling unit on the same lot shall be
protected with not less than 1/2€“inch (12.7 mm) gypsum board applied to
the interior side of exterior walls that are within this area. Openings
in these walls shall be regulated by Section 309.1. This provision does
not apply to garage walls that are perpendicular to the adjacent
dwelling unit wall.

Thanks for the reference. When in doubt, we will use Type X

3/8". 1/2", and 5/8" 5/8" for fire rating between house and garage -
required by some codes.

No more 1/4" sheet rock? :-)

I've always hung 5/8' in the ceiling, then 1/2" horizontal on the
walls. Garages may need the extra fire protection (longer time for
penetration). Ed gave you a good reply.

You mention Houston. A former poster, Heybub, lived in Houston (Harris
County) and implied there were no local building codes. You might see
a strip joint, bar and church built in close proximity to each other.

Simply said. Replace the size you take out... 5/8" or 1/2'.

P.S. Make a "high water mark" as a memory.

Unless of course there are building codes and what was code whenever
isn't code anymore. Building permit? Maybe they don't have those,
but if they do, better find out. There isn't that much difference
in the cost of the drywall, but if you have to do it over, there will be.

The last house we had built in
Ohio had two layers, both 5/8" thich. The layer next to the studs was
a fire brake material. The outer was ordinary drywall.

I've seen sheets of thick plywood at the house entry wall (fire
break), covered with just a 5/8". OP is dealing with Houston, TX. I'm
guessing he will figure out the needs.

There is no zoning in Houston, so you can indeed have an odd mixture of
commercial buildings in close proximity to residential areas and vice
versa. There have been several initiatives to implement zoning, but
every time a referendum has been held, the pro-zoning forces have failed
to muster enough votes to make it happen.

There are local building codes, but building codes are not the same
thing as zoning.

Exactly. The building/electrical/plumbing inspectors have been all over the place making sure that
all repairs meet the current building codes.

I confused myself between building and zoning. Thanks for the
correction.
