Frequently asked questions
How many licensed general contractors are in San Leandro?
304 active B licenses have a business address in San Leandro (CSLB, September 2026); 46% carry workers' comp and 53% are filed exempt.
Why does my workers' comp audit charge me for subcontractors?
If a sub cannot prove its own workers' comp coverage, carriers typically add that sub's payroll to your policy at audit. Collecting current certificates from every sub is the simplest protection.
