Requirements for doorway in Brick and Cinder block


For my addition, I am adding a half bath which the door will lead into the garage and the bath will be framed out in a section of the garage.

The garage wall is brick on the outside and cinder block.

What are the restrictions considering I will cut through this to create a door way?

Bracing?

How about the door? Does it have to be fire retardant?

On the other side of the studs, there will be insulation that are exposed to the open garage. Just plywood covering this?

The code guy in my town said this-not too sure what this means:

must be 1 hr. wall double 5/8 drywall[1 layer on inside and 1 on outside] . doorway in brick wall would requre lentil or beam.Wood in concrete contact at floor should be pressure treated or decay resistant . any penetrations have to be sealed and fire resistant.

The exposed studs have to be covered with 5/8 drywall. That's what he means by inside and out.

The lentil or beam is like a header that's designed for brick. It's either metal or stone that supports the brick above.

If you poke a hole(penetration), you have to seal it.

Your block wall portions have a fire rating high enough (probably 2 hours or better) so they do not have to becover for fire purposes.

The door should have a fire label on it.

Always enjoy your input....

(FWIW - I feel you're the go-to-guy for all concrete related questions - not saying that any other input has no merit)
