Legal Question in Business Law in California

You should have a written contract. What does it say about additional charges for this-and-that? To me it seems improper for home-maintenance contractors to ask an owner to leave the property unlocked; in many neighborhoods, this is quite unsafe. I would think the contractor could give you at least some notice by cell phone. Finally, it would be quite unreasonable to sue for a visit made without prior arrangements, and if you are sued, I'd say you would have a good chance of winning, unless this arrangement was set forth in your written contract.
