How to check a limited specialty contractor's license in San Dimas

  2. Re-check the same number on CSLB's Instant License Check the day you sign; our copy is refreshed weekly and 12% of San Dimas listings here already show a suspension.
  3. Match the license holder's name to the name on the written contract and the person you meet. Since 52% of San Dimas limited specialty contractors claim a workers' comp exemption, ask who will actually do the work. Hiring checklist.
