Mainline Insurance Services is the Chula Vista agency contractors call for workers’ comp — State Fund and private markets, class codes, dual-wage, same-day certs. Licensed brokers at 779 3rd Avenue. Call (619) 420-8600.
Mainline writes workers’ compensation for roofers, concrete, HVAC, electrical, landscaping, and other trades that actually get asked for a certificate. We shop State Fund and private markets instead of dropping every file into one carrier.
The premium is payroll and class codes. Dual-wage thresholds move every September 1 in California. If your hourly rate sits on the wrong side of the line, the audit puts that payroll on the expensive code. We set the file up so that does not surprise you at year-end.

Send the GC’s additional-insured wording to certs@mainline-ins.com. The in-office team issues from Chula Vista.
Hours: Monday–Friday, 8:00 a.m.–5:00 p.m. Pacific.
Get a workers’ comp quoteSeveral CSLB classifications already require a policy even with no payroll — roofing, concrete, HVAC, asbestos, and tree service among them. Anyone with a helper on the job needs it too. Calling that person a 1099 does not decide it for the board or the audit.
California splits many construction class codes by hourly wage. Pay at or above the threshold and you generally get the lower-rated code. Miss it and the audit bills the higher rate. The lines change every September 1.
During business hours we issue from the same office that placed the policy. Email certs@mainline-ins.com with the holder name and the form they want.
