“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.

LADBS requires permits for: structural changes, electrical work, plumbing changes, HVAC installation, roofing, window/door replacement (structural openings), ADUs, room additions, and any work valued over $500. Cosmetic work like painting, flooring, and cabinet hardware does not require permits.
Homeowners can do their own electrical work on owner-occupied single-family homes with a homeowner electrical permit from LADBS. However, the work must pass inspection. For multi-family, rental, or commercial properties, a licensed C-10 electrician is required.
For cosmetic projects (painting, landscaping, hardware), DIY saves 50-70% vs hiring a contractor. For structural/permitted work, DIY often costs MORE due to code violations, failed inspections, and rework. Average cost to fix unpermitted work in LA: $15,000-$50,000.
LADBS can issue stop-work orders, fines ($940+ per violation), and require retroactive permits (2x normal fee). At resale, unpermitted work must be disclosed and can reduce home value by 15-20%. Home insurance may deny claims related to unpermitted modifications.
Selective demolition (removing cabinets, non-load-bearing drywall, flooring) is a safe DIY task that saves $2,000-$8,000 on a typical remodel. Never demolish load-bearing walls, plumbing/electrical, or anything containing asbestos (common in pre-1980 LA homes) without a licensed professional.
