You carrier may have.
WC varies, in CA owners are not required
to have WC for themselves, only on employees.

You really need to shop for Liab.
I was quoted from several hundred a month
to several thousand. I thought I got a good deal until this thread. "275 a year" Now I'm
feeling like I've been ky'd

No matter what, do not work with out the
liab.
Even though your workmanship can be great,
shorts happen.
If a claim was made against a building/home
insurer and it was found that wiring you installed was at fault, that carrier will go
to your ins carrier. If you have no carrier
guess where they go for the money.....
