i run into difficulties with opening sizes in house plans
normally i have drawn all my construction plans with
the standard window and door sizes that caused never ever
a problem because the framer on jobsite added all rough opening sizes,
if necessary, mostly 2" or 2.5" wider
i have now moved to another province and all opening sizes in
the plans went wrong -to small- !
is there any regulation to draw additional the rough opening sizes
on plans ?
thank you for any advice
