Contractor deposit ??

[Ruth Bayang]

How much of a deposit/percentage is "customary" to give a contractor to rehab a house?

Or do you not give deposits at all? I have a Scope of Work, a Contractor Agreement with spelled out draws and project end date with per diem penalties.. just not sure if a deposit if necessary??

I know states like California have a law that it's $1000 or 10% whichever is less.
