Why This Matters on the Exam
I've been doing this for twenty years. Contract disputes are the biggest headache in this industry—worse than leaks, worse than inspectors, worse than dealing with HOAs.

Master contracts.
What You Must Know

For home improvement work in California, the law is strict. Oral contracts for home improvement over a certain threshold are completely unenforceable. You need writing. Every contract must clearly show who you are (name and license number), what you're doing (scope of work), how much it costs, when you're doing it, and the customer's cancellation rights.
