Best Floor Joist for Garage with apartment above
I am considering building a 28' X 30' Garage with an apartment above it. I am wanting to build it with no poles in the bottom so the whole garage is open. What is the best thing to use on the ceiling joists which will also be the apartment floor joists. One of my friends that builds said he would recommend the OSB I beam joists. I just wasn't sure if that would be better or if it would be better to put in a beam down the middle. Any opinions on this or maybe how you did yours.
