If you have obtained an owner-builder permit to perform electrical, mechanical, plumbing or gas work, you must perform all work yourself and you cannot subcontract or hire day labor employees. If you are a holder of a building permit, you can subcontract to licensed contractors, use day labor or persons to be paid on an hourly per diem basis for the building trade. However, you will be responsible for all work done by your employees. Anyone contracting (including labor) with you, verbally or in writing, on a fixed fee basis for any work, which is not properly licensed, will be subject to a fine of $500 and / or imprisonment for six months. Additionally, the hiring of an unlicensed contractor could subject you to a $5,000 fine.
