Licensed for this work
Structural work on a house — shoring, lifting, tying into framing — is B General Building work. (§7057)
Licensed, with a condition
A C-8 Concrete license covers forming and placing concrete, including foundations. If the job also involves lifting or shoring the structure or altering framing, that part is B work. Ask who handles the structural side.
D-30 covers pile driving and pressure foundation jacking specifically — underpinning and levelling, not a full rebuild.
Looks like it should cover this — but doesn’t
A B-2 may not make structural alterations to load-bearing walls or partitions, and is limited to improvements to an existing structure. (§7057.5)
Basis: B&P Code §7057; B&P Code §7057.5; B&P Code §7058. A California contractor may only contract for work within their classification (B&P Code §7059), with an exception for work incidental and supplemental to their own trade (16 CCR §831). This page reads the classification rules; it is not legal advice and says nothing about quality of work. Confirm with CSLB before signing.
