Need Info on interior door code

Dec 10, 2007 3 Replies

I am framing for an interior door in my basement. Someone was telling me that Ontario code says there has to be 2 top plates when framing ? I asked around and others didn't seem to think so. It's not a load bearing door at all. Does anyone know for certain if an interior door in a basement has to have 2 top plates ? I only put one.


So call your citys building inspector dept.

It's considered a partition wall. Most codes allow a single top plate for a partition wall.

My 1970 copy (obsolete, I know) of "Canadian Wood-Frame House Construction" put out by CMHC, shows that non-load bearing interior walls only require one piece of 2" framing lumber over a door opening.
