“CSLB license verification is non-negotiable before signing any construction contract in California. Go to CSLB.ca.gov, search by license number, and verify: the license is current and active, the license type matches the scope of work (B-General, C-specialty trade), the insurance and bonding are current, and there are no disciplinary actions. Takes 5 minutes. Do it every time.”
Request a payment bond on any project over $50,000. A payment bond ensures that subcontractors and material suppliers are paid even if the general contractor defaults. Without a payment bond, you can be required to pay twice for the same work if the GC fails to pay their subs. Payment bonds cost 1–2% of the contract amount — the cheapest insurance available.

What is contractor retention in California?
Retention is a percentage of each progress payment (typically 5-10%) that the homeowner withholds until the project is complete and all punch list items are resolved. It incentivizes the contractor to finish the job properly. California Business and Professions Code Section 7159 governs payment schedules and retention for home improvement contracts.
Selecting the right contractor for California contractor retention law homeowner in Los Angeles is critical to a successful project. Here are key factors to evaluate:
Licensing: Verify the contractor holds an active California General Contractor B-license through the CSLB website. Check for disciplinary actions and bond status. NP Line Design holds License #1105249 with zero complaints.
Insurance: Require proof of general liability ($1M minimum) and workers' compensation. Uninsured contractors expose you to personal liability for on-site injuries.
Portfolio: Review completed projects similar to your scope. Ask for references from recent clients in your neighborhood. Visit an active jobsite if possible.
Written proposals: Get detailed proposals (not just estimates) with fixed pricing, scope of work, materials specification, timeline, and payment schedule. Never pay more than 10% upfront (California law limits deposits to $1,000 or 10%).

Design-Build Portfolio
Retention is a percentage of each progress payment (typically 5-10%) that the homeowner withholds until the project is complete and all punch list items are resolved. It incentivizes the contractor to finish the job properly. California Business and Professions Code Section 7159 governs payment schedules and retention for home improvement contracts.
California law limits contractor deposits to $1,000 or 10% of the contract price, whichever is less. Any contractor demanding more is violating BPC Section 7159. Progress payments should be tied to completed and inspected milestones, not calendar dates. Never pay for work not yet performed.
Release retention after: all work is complete per the contract scope, all punch list items are resolved, all LADBS inspections have passed including final, the contractor provides unconditional lien waivers from all subcontractors, a Notice of Completion has been filed (starting the 30-day lien period), and you are satisfied with the workmanship.
Steps: 1) Document issues in writing with photos, 2) Send certified letter requesting completion within a reasonable time (10-15 days), 3) If unresponsive, file a complaint with CSLB (they mediate disputes), 4) Use the retention funds to hire another contractor for punch list work, 5) File in small claims court for damages. California CSLB contractor bonds provide an additional recovery avenue.
NP Line Design follows California law strictly: no more than $1,000 or 10% at signing. Progress payments are tied to completion milestones (framing, rough MEP, finish, etc.). We provide a detailed payment schedule in every contract with milestone descriptions. Final payment is due after final inspection and punch list completion. We welcome retention holdbacks as they align our interests.
