A contractor was hired for remodeling in California
The contractor didn't test hazardous material in the condo before starting the work.
If the condo is contaminated. Whose shall fulfill the bill?
Hopefully you hired a licensed contractor. The contractor should have insurance coverage. You should inquire to your contractor if they have liability insurance and also put them on notice of a possible claim... and while you are at it ask them if there is a possibility that your condo has asbestos and why didn't they safeguard against this.
Yes, you have potential liability if your contractor contaminated the neighbor's property.
How old is your building?
Were any tests done for asbestos before the work started?
To protect yourself you might want to hire an Industrial Hygenist or testing company to inspect your property and make sure it is not contaminated!
