That workman from Craigslist who dropped by to install a set of office cabinets for you "off the books" is now more likely to be headed to jail, no matter how happy you are with the quality of his work, thanks to the California legislature:
Gov. Jerry Brown has signed S.B. 315, described by its sponsor, Sen. Ted Lieu (D-Beverly Hills), as a measure “to help curb California’s underground economy.” The measure would step up penalties and enforcement against persons who advertise for, or perform, repair and construction work with a value of $500 or more, counting parts and material as well as labor. ... First offenses are subject to six months in jail and a $5,000 fine, and subsequent offenses are treated yet more harshly.
There’s more. The bill, according to its legislative summary, “would additionally require that the enforcement division, when participating in the activities of the Joint Enforcement Strike Force on the Underground Economy, be granted free access to all places of labor,” at least in business locations. (Yes, “all”; you only thought your property was private.)
A special touch: the customer who ordered the work will now be legally classed as a "victim of crime" entitled to restitution and other benefits, even if the work was done exactly as ordered, and even if (the law is explicit) the customer was fully aware the job was unlicensed.
How could the California legislature have unanimously (as it did) passed a measure curtailing property rights by giving more state inspectors access to places of labor against owners' will? Simple: it was framed as a pro-business measure. Among its backers were the sponsoring Contractors State License Board and such groups as the Air Conditioning and Refrigeration Contractors Association, the electrical contractors, the landscape contractors, the plumbing and heating contractors, and so forth.
The costs of occupational licensure are many. Not least is that it gives established businesses a stake in making government more powerful and invasive.
P.S.: Possibly unrelated, or possibly not: California issued massive fines that closed down a small winery whose owners were allowing volunteers to do some work, in violation of state law; a state spokesman said permitting volunteer labor "isn't fair" to competing wineries with all-professional staff.
