Is this a labor law violation in Calif?

[Alfred Bell]

I'm thinking about getting an owner/builder worker's comp insurance policy so that I can engage a few guys to do a condo remodel for me. I want them covered with workers comp to avoid any liability lawsuit if anyone gets injured.

I don't want to do the payroll thing (FICA, FUCA, SS, Medicare, unemployment, etc. etc.). I will just notify them in writing that they are responsible for their own taxes, and pay them weekly, and then at the end of the job (which will only take 3-4 weeks) I will 1099 them.

Is this acceptable or would I be violating some labor, payroll or employment law?

Thanks in advance for any assistance,
Alfred
