OK, Harold; thank you for the LV stuff, & the Home Improvement Contractor Registration Act.
Guys:
Enforcement of the UCC (think of it as the overall building code) is the responsibility of the CO (Construction Official) The CO, and the 'Sub-Codes' (Elec.,Plumb., Bldg., Fire all have the authority to impose monetary fines for working without required permits.
As to someone working without a license (Elec/Plumb/Fire/Locksmiths/B&F Alarm) they are fined or jailed by the various Boards of Examiners.
Everyone falls under the two (2) DCA's, Dept of Consumer Affairs, or Dept of Community Affairs. Ultamately, back to the State Attorney General, who is 'in-charge' of the whole enchalada.
Working without a permit is a max of $2000 now, up from the max of $500, written and collected by the Construction Official.
