Hiring a California foundation contractor
At a glance: California’s contractor board tells consumers to verify a license before hiring.[1] For Unlimited Drilling & Foundations Inc, that record is license 682396, which was current and active when this page was compiled.[2]
Check the license first
The Contractors State License Board tells California consumers to hire licensed contractors and to verify the license before signing a contract.[1] For this company, the number to check is 682396. Confirm that the license is still current and active, that the classifications cover the work, and that the business name on the contract matches the license.[2]
Get the agreement in writing
Home-improvement work in California is subject to contract rules that, among other things, call for a written agreement on work above a low dollar threshold.[1] The contract should describe the scope, the method, the price or the way the price will be determined, the approximate start and substantial-completion dates, and any allowance for engineering or unforeseen conditions. It should also say who pulls the permit.
Bonds are not a full safety net
The $25,000 contractor’s bond on this license is a licensing requirement.[2][3] It is not automatically a completion guarantee for a large hillside project. If a job is large enough to warrant a performance or payment bond, that has to be negotiated in the contract.[3]
How this company fits the checklist
The firm publishes a license-check link, names a president, and holds A and B classifications that are relevant to general engineering and general building work.[4][2] It also claims in-house performance and a long project history, which a customer can ask it to document.[5] This wiki does not turn those claims into a recommendation. It is a reference, not a referral service.
Insurance, permits and change orders
Besides the license check, owners commonly ask for a certificate of insurance and for written confirmation of who pulls the permit. The CSLB snapshot for this license shows a workers’ compensation policy with State Fund, but that snapshot is dated 9 November 2026 and is not a substitute for a current certificate sent to the owner or the owner’s agent.[2] Auto and general-liability certificates are not transcribed here, because they were not on the license-detail page used for the original-data article.
Change orders are where hillside jobs often grow. Unforeseen utilities, deeper refusal, extra shoring, or a revised engineer’s detail should be priced in writing before the work proceeds, not only described in a conversation. The company’s published cost drivers — size, time and extra equipment or materials — are a reminder that those extras are normal points of negotiation, not automatically a surprise attack.[6]
This wiki is not a referral and does not score contractors. The checklist on this page is the Board’s consumer advice plus the public facts about license 682396.[1][2]
