What insurance should a startup review before signing a lease?

For a California quote, list owned or leased business buildings, business property, and property of others separately from CGL. Compare the lease’s insurance wording with that inventory.

Ask how the quote lists locations, tenant improvements, equipment, inventory, and others’ property, including values and deductibles.¹

If the lease asks for a certificate, additional-insured status, or policy change, ask which document or endorsement reflects it and whether the policy needs an amendment. Confirm timing before relying on it.¹
