I like the way you think. These are exactly the things I worry about--and more.I don't know anything about CA law, but I have to wonder: What is this contractor providing you that a handyman does not? Does he have his own employees and will the work be performed by an employee as opposed to a mystery subcontractor? If so, let the contract state that the work will be performed by an employee of the contractor. Liens are only part of the story. What if the laborer places his/ her ladder in a rabbit hole and takes a tumble? That could mean a lot more than a $400 lien. Has the contractor provided a some additional clauses in the contract that that inure to your benefit, i.e. that the contractor is fully responsible for the means and methods of the work, that he will provide equipment and supplies, that he carriers workers' compensation coverage for the employee performing the work, that he will have you named as an additional insured on his (liability) policy, that there will be no workers' exclusions on said liability policy, that he will defend and indemnify you against any claims arising in full or in part out of the work to the fullest extent of the law, etc.?
I required an indemnification/ insurance clause, etc. by the neighbor's tree contractor before I would agree to permit him to remove limbs from one of my trees. And when my real estate broker tried to slip a defense and indemnification clause to its benefit into the RE contract - I had that clause removed before I would sign the contract.
In this case, the attached notice may just be putting you on notice of existing local laws, as opposed to altering your rights but, I don't know this.
Very cool you got the real estate broker to change the contract to your liking. I might need some tips on that in the next year or so.
Are you sure you don't play a lawyer on TV?
