Adu Construction Inc has held a CSLB class-B licence for 0 years (since 2025). Newer entrant — ADU specialist market has seen rapid licensing growth post-2017.
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: Exempt. This typically means the firm has no W-2 employees and operates with the owner-operator alone (or with subcontractors who carry their own coverage). California requires W-2 employees to be covered. If this builder grows mid-project and hires staff, they must obtain coverage before those employees begin work.
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.
