John, i don't know what the fine is for unpermited work. as NORCAL mentioned the CSLB (contractor state license board) does limit what the handyman can charge without a license.
Starting Jan. 1, those caught contracting in California without a license for the first time will face six months in jail or a fine of up to $5,000 because of a new law that will take affect. Right now the offense is only considered a misdemeanor with no set jail time or penalties.
