Los Angeles has thousands of licensed contractors — and an unknown number of unlicensed ones. The difference between hiring the right contractor and the wrong one can mean the difference between a successful renovation and a construction nightmare: abandoned projects, shoddy workmanship, liens on your property, or work that doesn't pass inspection.
At Archimod, we're a licensed, design-build construction firm in Los Angeles, and we've helped clients who came to us after bad experiences with previous contractors. This guide gives you the tools to evaluate any contractor before you sign a contract.
California law requires all contractors working on projects over $500 to be licensed by the CSLB. You can verify any contractor's license instantly at cslb.ca.gov. Look for an active license, the appropriate license classification for your project (B-General Building Contractor for most renovations), and no disciplinary actions on their record. Never hire an unlicensed contractor — if work is performed without a proper license, permits cannot be pulled, inspections will fail, and your homeowner's insurance may not cover damages.
Ask for a certificate of insurance showing general liability coverage (minimum $1M per occurrence) and workers' compensation insurance. Without workers' comp, you as the homeowner can be held liable if a worker is injured on your property. Verify that the policy is current — some contractors show certificates for expired policies.
Ask for 3–5 references from projects similar in scope and budget to yours, completed within the last 12 months. Call those references. Ask: Did the project come in on budget? Was the timeline met? How was communication? Would you hire them again? References from five years ago or for dramatically different project types are far less useful.
Any reputable Los Angeles contractor should be comfortable navigating the LADBS permitting process. Ask specifically whether they'll pull all required permits for your project and whether their experience includes projects that required structural engineering, Title 24 energy compliance, or fire sprinkler updates. Contractors who suggest skipping permits are a serious red flag.
California law limits the down payment a contractor can request to 10% of the contract price or $1,000, whichever is less, for home improvement contracts. Be wary of any contractor demanding large upfront payments. A reasonable schedule ties payments to construction milestones (framing complete, rough MEP approved, finishes installed, final inspection passed).
Most general contractors subcontract specialty work (electrical, plumbing, HVAC, tile). That's normal and acceptable — but ask how they vet and supervise their subs. Does the same superintendent oversee all subs on-site daily? Are the subs licensed for their trade? The quality of a project depends as much on who installs the work as it does on the GC who manages the job.
Insist on a line-item bid that clearly specifies scope, materials, labor, and exclusions. Vague bids like "kitchen remodel including cabinets and counters, $45,000" leave enormous room for disputes. A professional contractor provides specific material specifications (brand, model, finish) and unit pricing so you can compare bids apples-to-apples.
Every renovation involves unexpected discoveries — old wiring, plumbing issues, structural surprises. Ask how the contractor handles change orders: Are they in writing? Signed before work proceeds? Priced transparently? A contractor with a clear, fair change-order process will handle surprises professionally. One without a process will use change orders as a mechanism to inflate your final bill.
You deserve to know what's happening on your project. Ask about their communication process: Do they provide weekly written updates? A dedicated project manager? Access to a project management app? Regular site walks? Good communication prevents surprises and keeps you in control of your project.
California law provides a 10-year statutory warranty on structural defects and a 4-year warranty on other construction defects. But reputable contractors typically offer their own written warranty above and beyond the minimum. Ask what's covered and for how long.
