Southworth Construction LLC operates out of Temecula in Riverside County and carries CSLB license #1042704, classification B — General Building. At the time this listing was compiled, the license was active with no suspension recorded.
This classification covers projects that cross trade lines — additions, second stories, ADUs, structural alterations, whole-house renovations and post-loss reconstruction. A general contractor can perform or subcontract the individual trades, but the permit and the schedule sit with them.
Working in southwest Riverside County: A lot of newer neighborhoods here sit under HOA architectural review, which adds an approval step before exterior work can start.
Before you hire any general contractor: On a project of any size, ask for the payment schedule in writing before work starts. California caps the down payment on home improvement contracts at $1,000 or 10% of the contract price, whichever is less — progress payments after that should track completed work, not the calendar.
License status can change at any time. Confirm license #1042704 is current, and check bond and workers’ compensation coverage, using the CSLB license lookup before signing a contract or paying a deposit.
