I've been parsing a few threads related to this and thought that I
would chime in.
Home Inspectors are a joke. They have tried to credential themselves
out of being a joke but they are still a joke.
PE's who have no specific familiarity with residential construction
are somewhat less of a joke but are still a bad joke.
AIA guys are sort of like PE guys, if they do not have a background in
residential. These guys can really be an expensive joke.
"Designers" are the biggest joke of all and they have several subsets,
all of whom have credentialing entities behind them. Some are kitchen
designers, some are just general designers, most of them call
themselves "Interior Designers" and they all suck.
Inspectors are a really, really bad joke. In the old days these jobs
were filled by retired builders and carpenters. That was fine. They
shouldn't have changed it. Now we have young'uns who quote the code
without understanding. I don't like them.
But they have credentials.
