California requires all contractors performing work over $500 (labor and materials combined) to hold a valid license from the Contractors State License Board (CSLB). This is non-negotiable. An unlicensed contractor cannot legally pull permits in California, which means any work they do that requires a permit is automatically unpermitted.
Verify a license directly on the CSLB website at cslb.ca.gov before signing anything. Check that the license is active, that it covers the correct classification for your project (typically B-General Building Contractor for kitchen and bathroom remodels), and that there are no disciplinary actions on file. All YOYO projects are run by CSLB-licensed general contractors. See our about page for licensing details.
A licensed contractor should carry two types of insurance: general liability and workers' compensation. General liability protects your property if the contractor's work causes damage. Workers' compensation protects you from liability if a worker is injured on your property. Ask for insurance certificates directly from the contractor's insurer, not just a verbal confirmation. Verify that the policy limits are adequate for your project size.
Contractors who work with subcontractors (which is standard for kitchen remodels involving multiple trades) should verify that their subcontractors are also insured. Ask explicitly whether the workers on your job will be direct employees or subcontractors, and whether subcontractor insurance is verified.
Any kitchen remodel involving plumbing, electrical, gas, or structural work requires a building permit in California. Your contractor should pull permits as part of their standard process, include permit costs in their proposal, and coordinate all required inspections. A contractor who suggests skipping permits to save time or money is a red flag.
Ask which specific permits will be required for your project, when they will be submitted, and how permit timelines are factored into the project schedule. In cities like Oakland and Long Beach, permits can take 4 to 8 weeks. The contractor should account for this in their timeline estimate, not treat it as an afterthought. Read our full California permit guide for more detail by city.
California law limits down payments on home improvement contracts to 10% of the total contract price or $1,000, whichever is less, for most residential projects. Any contractor asking for more than this upfront is violating state law. Be cautious with any contractor who requests a large initial payment before work begins.
A standard payment schedule ties payments to project milestones: a small deposit at signing, a payment at material delivery or demolition, a mid-project payment at a defined construction milestone, and a final payment at project completion and punch list sign-off. Get this schedule in writing in the contract.
Photos or references from a project similar in scope and budget to yours give you a realistic sense of the contractor's finish quality. A contractor who has done ten full kitchen gut renovations has a different skill base than one who primarily does cosmetic refreshes. Ask specifically for references from projects of comparable complexity to yours, and follow up with at least one past client by phone.
When reviewing photos, pay attention to cabinet installation alignment, countertop seam placement, tile layout at corners, and how trim meets flooring. These details reveal installation quality more reliably than hero shots of completed kitchens.
Ask for a written project schedule before signing. A credible contractor can give you a phase-by-phase timeline showing design finalization, permit submission and expected approval, material ordering and delivery, demolition, construction phases, and final punch list. Ask what factors could realistically extend the timeline, such as cabinet lead times, permit delays, or unforeseen conditions during demolition.
Be skeptical of timelines that seem unusually fast. Cutting corners on permit processing or skipping inspection steps might accelerate the schedule but creates compliance problems that affect you long after the contractor has moved on to the next job. See our detailed kitchen remodel timeline guide for phase-by-phase benchmarks.
A detailed, itemized quote breaks down labor, materials, permits, and any contractor markup separately. This serves two purposes. First, it lets you compare bids apples-to-apples rather than trying to interpret lump-sum numbers from three different contractors. Second, it makes change orders clearer if the project scope shifts, because you can see exactly which line items are being added or modified.
Be wary of quotes that are vague about material specifications. A quote that says "countertops — $4,500" without specifying the material, brand, thickness, and edge profile leaves room for the contractor to install a cheaper product than you discussed. Every material selection should be named specifically in the contract.
Homeowners who ask these questions before signing are far less likely to face mid-project disputes, cost overruns from vague contracts, or post-project problems from unpermitted work. At YOYO, all of our partner contractors answer these questions as part of the standard onboarding process, which is one reason our clients rarely encounter the surprises that are common with unlicensed or under-insured contractors.
