Global Modular Inc has held a CSLB class-B (General Building) licence for 22 years (since 2004). Long-tenured contractor by California standards — most ADU specialist firms are post-2017 entrants drawn into the market by SB 1069 and AB 2299.
Business structure: Corporation. Corporate-form contractors carry separate liability protection from the owner's personal assets. Verify the corporation is in good standing with the California Secretary of State's business search before signing.
Contractor's bond posted: $25,000 — the California statutory minimum for class-B contractors. Standard for the industry.
Workers' compensation coverage: Leasing Firm, Temp Agency, etc.
A California class-B (General Building) contractor licence authorises the holder to take on building projects requiring at least two unrelated trades — framing + electrical, or concrete + plumbing + framing, etc. Almost all ADU work qualifies because an ADU is by definition a complete dwelling and requires multiple trades. A single-trade contractor (class C-10 electrical, C-36 plumbing, etc.) cannot prime an ADU project as general; they must subcontract under a B-licensed prime, or the homeowner must act as their own owner-builder.
This is a necessary condition, not a sufficient one. ADU construction has specific code requirements (Title 24 energy compliance, fire sprinklers in most jurisdictions, soils reports on sloped lots, accessibility provisions for JADUs) that not every B-licensed contractor has experience with. Ask for at least three completed ADU project references before committing.
