Re: what's wrong?

[Subject Prev][Subject Next][Thread Prev][Thread Next]
In our area, we've been on the IBC for about 5-6 years and 
residential construction falls under the IRC which generally
doesn't require a soils report or many of the other things
that the IBC requires.

It was kind of weird to get used to having two different codes,
one for commercial and one for residential, but that's the
way that they get used here.

You may want to check the IRC for the soils report requirements
for residential construction.

Has the CBC employed the IRC as a separate document like the ICC has?

Take Care,
