Business & LicensingQuestion 624 of 1605

Under the CSLB's classification rules, a C-specialty contractor may take a prime contract that involves work outside its classification only if:

a.The work outside the specialty is incidental and supplemental to the performance of the contract in the licensed specialty
b.The contractor obtains a temporary cross-classification permit from CSLB
c.The owner signs a written waiver acknowledging the contractor is unlicensed for that trade
d.The added work is less than $5,000

Explanation

Bus. & Prof. Code §7059 and CCR Title 16 §831 allow a specialty (C-) contractor to perform work outside its classification only when that work is 'incidental and supplemental' to the work in the contractor's licensed classification. There is no $5,000 carve-out, no 'temporary cross-classification permit,' and an owner waiver cannot legalize unlicensed work — §7031 still denies compensation to an unlicensed contractor for work requiring a license. The 'incidental and supplemental' test is fact-specific and frequently litigated.

Law Reference: Bus. & Prof. Code §7059
