Independence note: UnlimitedDrilling.wiki is an independent record compiled from the Contractors State License Board, Google Business Profile data, and the company’s own pages. It is not the official website of Unlimited Drilling & Foundations Inc. Figures the company publishes about project counts, methods or schedules are attributed to the company. Hours, addresses and license status can change; confirm them with the company at (619) 871-7880 and verify the license at the Contractors State License Board.

The license number and status

Unlimited Drilling & Foundations Inc holds California contractor license 682396.[1] The Contractors State License Board detail page, captured for this wiki on 9 November 2026 at 8:22 p.m. Pacific Time, shows the license as current and active.[1] It is a corporation license, first issued on 20 December 1993, reissued on 25 January 2012, and scheduled to expire on 31 January 2028.[1]

The official company page tells visitors to check the license at CSLB.[2] That is the right habit. A wiki snapshot can go stale the day after it is published if a bond lapses, a qualifier disassociates, or a status changes.

Classifications A and B

The license carries two classifications: A, General Engineering, and B, General Building.[1] CSLB describes Class A as the classification for contractors whose principal business is in connection with fixed works that require specialized engineering knowledge and skill, including (among other things) irrigation, drainage, work on waterways, and related infrastructure.[3] Class B is the classification for contractors whose principal business is in connection with any structure built, being built, or to be built for the support, shelter and enclosure of persons, animals, chattels or movable property, requiring two or more unrelated building trades or crafts.[4]

Those classification descriptions matter because they define the kind of work a contractor is authorized to take as a prime. Foundation repair, caisson drilling, retaining walls and drainage on a hillside can fall under general engineering, general building, or both, depending on the job. A customer should still ask, in writing, which classification the firm is using for a particular contract and whether any specialty classifications (for example, a C-8 concrete or C-53 work that is not on this license) will be needed from another licensee.[5]

Bond and workers’ compensation

CSLB shows a contractor’s bond filed with American Contractors Indemnity Company, bond number 100183039, in the amount of $25,000, effective 1 January 2023.[1][6] A contractor’s bond is a licensing requirement, not a job-completion warranty and not a substitute for a performance bond on a large contract.[6]

Workers’ compensation is listed with the State Compensation Insurance Fund, policy 1429467, effective 1 November 2014 and expiring 1 November 2027, with classification codes 6218 and 6205 displayed without a description on the public page.[1] CSLB notes that it does not verify the accuracy of those classification codes.[1]

The qualifier

Howard Joseph Azar is the qualifying individual and, according to the record, certified that he owns 10 percent or more of the voting interest, so a Bond of Qualifying Individual is not required.[1] The official website names Joe Azar as president.[2] See the people article for how this wiki treats the two names.

Mismatches to read carefully

Two fields on the license do not match the official website exactly. The license address is 9827 River Street, Lakeside, CA 92040; the website and Google listing use 9565 Abbeyfield Road #2602, Santee, CA 92071.[1][7][8] The license phone is listed as (719) 871-7880; the website and Google use (619) 871-7880.[1][7] This wiki reports both and uses the Santee office and the 619 number for the public NAP block, because those are the details the company gives customers.

Questions readers ask

Is the license active?

It was current and active on the CSLB page as of 9 November 2026. Check the live record before hiring.

What does A and B cover?

A is general engineering; B is general building. The official CSLB classification pages define the scope.

Does a $25,000 bond cover a large hillside job?

No. That figure is the licensing bond amount on the record, not a project performance bond.
