Residential Builder License

Residential work sits with a different board and a much lower trigger — $5,000 for a residential builder, covering buildings up to three floors with no more than sixteen units in a single apartment block. A specialty trade has a lower trigger still, at $500, and which credential you get depends on the trade rather than the money: plumbers, electricians and heating and air installers must pass an examination and receive a license at $135 plus $220, while siding installers, masons, drywall installers, carpenters, stucco installers, painters, paperhangers and solar panel installers merely register at $100 with no examination. Renewing late costs $50 for a license or $20 for a registration; reinstatement within three years is $260 or $90. The commercial consequence of getting this wrong is severe and often overlooked: an unlicensed or unregistered residential contractor may not file a mechanics' lien and may not bring any action to enforce its own contract, so an unpaid job simply cannot be sued for.
