Bad General Contractor in California — What Are Your Legal Rights?

Common General Contractor Defects in California

When general work fails to meet professional standards, California law allows homeowners to recover the full cost of repair or replacement. Common general defects that support legal claims include:

• Project managed poorly resulting in defective work by multiple subcontractors
• Failure to coordinate trades leading to costly rework
• Subcontractors not paid, resulting in mechanic's liens on your property
• Building code violations across multiple trades
• Failure to obtain required permits for any or all phases of work
• Project abandoned mid-construction leaving the home uninhabitable
• Unauthorized substitution of materials across the entire project
• Overbilling through manipulated change orders

Even if the defect is not yet causing visible damage, it may be creating conditions that will lead to serious problems. An independent inspection by a licensed general professional is the most important step you can take — it establishes that the work is defective by professional standards, not merely your opinion.

General-Specific License Requirements in California

General contractors in California hold a B General Building classification. A B license authorizes work on structures requiring at least two unrelated trades — framing plus electrical, or plumbing plus tile, for example. A general contractor is legally responsible for the work of their subcontractors and cannot disclaim liability by blaming a subcontractor. As of January 1, 2026, under SB 517, general contractors on home improvement projects must disclose which subcontractors will be used.

Verify your contractor's license at cslb.ca.gov before taking any legal action. Check the classification, the effective dates, and any disciplinary history. A contractor who performed general work outside their license classification is functionally unlicensed for that work — and your §7031 disgorgement rights apply.

Your Legal Remedies for Bad General Work

General contractor disputes are often the most complex because they involve multiple trades, multiple potential defects, and the additional issue of unpaid subcontractors. Your legal strategy should address all of these simultaneously. Obtain lien releases from all subcontractors before making final payment. If subcontractors have already placed liens, address those first — a mechanic's lien attorney can help you remove improper liens while you pursue the general contractor.

In most cases, the fastest path to recovery involves three simultaneous actions: (1) a formal demand letter giving the contractor one final opportunity to fix the work, (2) a CSLB complaint establishing an official record of the contractor's misconduct, and (3) a bond claim if the contractor is licensed. If the contractor does not respond appropriately, a civil lawsuit follows.

What to Document Before Taking Any Action

• Photographs and video of all defective work, date-stamped
• Independent inspection report from a licensed general professional
• The original contract, all change orders, and all invoices
• Proof of payment — checks, bank transfers, credit card statements
• All written communications — texts, emails, letters
• Building permits and inspection records — including any failed inspections
• Written bids from replacement contractors to repair the defective work
