For contractors, insurance isn't just about protection—it's about compliance and getting hired. Most commercial and residential clients won't let you walk onto a job site without a "COI" (Certificate of Insurance).
What Happens If You Work Without Insurance?
Working uninsured is a massive risk. You face:
- Contract Rejection: Large developers and savvy homeowners will skip your bid.
- Personal Liability: You are personally responsible for any damage your team or tools cause to a client's home.
- State Fines: States like CA and NY have strict mandates for contractors.
