The home is in Tacoma WA. Plans were submitted and approved

Customer Question

The home is in Tacoma WA. Plans were submitted and approved for a major remodel. I remember the planner telling me about 5/8" and 1/2" drywall. I am now at the drywall stage and can't remember what he said. When do I need 5/8" drywall?

for one 5/8 is much more rigid, and a better fire rating ........... and maybe you were going with plaster veneer walls

Customer: replied 1 year ago.
No.
Expert:  Eddie replied 1 year ago.

was it because of custom doors?

Expert:  Eddie replied 1 year ago.

sound proofing?

Customer: replied 1 year ago.
My understanding in perusing IBC, Tacoma Building Codes and multiple web searches is that 5/8 is required on exterior walls and other interior walls under certain conditions. What are those conditions?
Customer: replied 1 year ago.
I know it has something to do with fire rating.
Expert:  Eddie replied 1 year ago.

it must be the fire rating ..............I'm 3000 miles away so codes are a bit different

Expert:  Eddie replied 1 year ago.

do you remember him saying use on ceilings ?

Customer: replied 1 year ago.
According to IBC the only requirement for ceilings to use 5/8" is 24" oc spacing.
Expert:  Eddie replied 1 year ago.

because it is much more rigid like I stated........but I thought for fire rating if it was a two story and not being able to burn through to the roof so fast ..........I only use 5/8 drywall for my house ...............a much nicer job for taping too

Expert:  Eddie replied 1 year ago.

use as many 10 foot boards as you can too ..............less butt seams

Customer: replied 1 year ago.
Do you know when 5/8 fire rated sheet rock is required? The home is 1.5 stories, the floors, ceilings and walls(interior and exterior ) are 1" tongue and groove.

Also, the garage is detached and more than 5' from the house.

I could speculate but you would be much better finding out the specific codes for your town.........you would have to pay for the building code book........... but you would be much better off contacting a local contractor for a free estimate and he will tell you right off
