I was told that I could not do the work myself but I didn't say the magic
words "owner/builder permit".
I will call back using this phrase and see what happens.

You can probably find out everything you need online if you live in a county
that owns a computer. I was able to download all my permit applications and all
the rules.
It will be something like "community development" or "building services" on the
county/city web site.
