Once a home improvement job at your rental tops $500 total, California law requires a written contract with a license number, itemized pricing, and cancellation rights. A handshake doesn't cover it.
If you hired a contractor for a $600 repair on a handshake, you already have a legal problem, and it isn't the contractor's alone. Under California Business and Professions Code Section 7159, once the aggregate contract price for labor, services, and materials exceeds $500, the deal has to be in writing. A verbal agreement past that line isn't just informal. It's noncompliant.
Five hundred dollars doesn't buy much home improvement work these days. A water heater swap, a section of fence, a bathroom fan replacement, most jobs an owner without a management company calls in clear that threshold without anyone noticing. And the number in the statute isn't a soft guideline. It's the trigger for a specific written contract requirement under Section 7159, and it applies to the total job cost, materials included, not just labor. If you got a verbal quote for "around $400" and the final bill landed at $650, you were already past the point where a written contract should have existed before work started.
I wrote about checking a contractor's CSLB license before you hire them a while back, because that's the first thing to confirm. This is the next step. A licensed contractor and a legal contract are two different boxes to check, and skipping the second one leaves you exposed even when the person doing the work is fully licensed.
Section 7159 isn't a loose formality. It spells out specific required contents, and if your paperwork is missing them, it isn't a compliant contract even if both sides signed something. The requirements include:
This is the piece that catches even careful owners off guard. Under Section 7159, the deposit a contractor can legally collect upfront is capped: "THE DOWNPAYMENT MAY NOT EXCEED $1,000 OR 10 PERCENT OF THE CONTRACT PRICE, WHICHEVER IS LESS." On a $600 repair, that means the legal maximum down payment is $60, not a flat $200 "to get started," which is the kind of number I hear owners mention without questioning it.
It's also worth knowing the mirror image of this rule: a contractor collecting payment for work not yet completed is not just bad practice, it's against the law. Progress payments are supposed to track actual progress, itemized and dated, not loaded up front against future promises.
None of this means you need a lawyer standing by for every repair call. It means that once a job at your property is going to run past $500 total, you should expect a written contract before anyone touches a wrench, and you should actually read it for the pieces above: license number, itemized schedule, the mechanics lien warning, and a down payment that doesn't exceed the lesser of $1,000 or 10 percent. A contractor who resists putting any of that in writing is telling you something about how they operate, regardless of how the work itself turns out.
When Schofield manages a property, this paperwork is standardized before a vendor ever starts a job, so it's one less thing an owner has to track personally. Managing the property yourself doesn't mean you can't get the same protection. It means the checking is on you.
Does the $500 threshold include materials, or just labor?
Both. The statute counts "the aggregate contract price specified in one or more improvement contracts, including all labor, services, and materials to be furnished by the contractor." A job with cheap labor but a pricier fixture or part can cross the $500 line on materials alone.
What if I already paid a contractor more than 10 percent upfront?
That's a sign the contract terms weren't compliant, and it's worth raising with the contractor directly, in writing, before the job goes further. It doesn't undo the payment, but it's useful to document for your own records, and it should inform whether you keep working with that contractor.
Can a contractor split one job into smaller contracts to dodge the $500 rule?
The statute looks at the aggregate price across "one or more improvement contracts" tied to the same work, which is meant to close exactly that gap. If a single project gets carved into pieces that each land just under $500 with no real reason for the split, that's worth questioning.
