4.5 Contract Breach, Warranties & Dispute Resolution

Contract Breach, Warranties & Dispute Resolution

Breach of Contract and Available Remedies

A breach of contract occurs when a party fails to perform an obligation the contract required — a contractor who abandons a job mid-installation, or a homeowner who refuses to pay for completed, conforming work. California recognizes several remedies:

• Damages — money to compensate the injured party, often measured as the reasonable cost to complete or correct the work using another contractor, plus any foreseeable consequential losses.
• Specific performance — a court order compelling the breaching party to complete the promised work, which is rare in construction disputes since courts are reluctant to supervise ongoing performance.
• Rescission — unwinding the contract entirely and restoring both parties to their pre-contract position; this is the remedy tied to a defective HIC discussed in Section 4.1, though even then the contractor may recover the reasonable value of completed work.
• Liquidated damages clauses — a pre-agreed dollar amount, often per day of delay, that substitutes for proving actual damages; these must be a reasonable, good-faith estimate of likely harm at the time of contracting, not a punitive penalty, or a court may refuse to enforce them.

For civil lawsuits, as opposed to a CSLB administrative complaint, the general statute of limitations for breach of a written contract in California is four years under Code of Civil Procedure §337; for an oral contract, it is two years under §339. This is one more reason a fully documented, signed HIC benefits a contractor as much as a homeowner — it defines exactly what was promised and starts a clear, longer limitations clock.

Implied Warranty of Workmanlike Quality

Even without a single word about warranties in the contract, California law implies a warranty of workmanlike quality: that a contractor's work will be performed in a manner consistent with the standards of the trade, free of significant defects, and fit for its intended purpose. A heat pump installed with an undersized refrigerant charge, mismatched equipment tonnage, or ductwork that starves half the house of airflow can breach this implied warranty even if the written contract never used the word warranty.

Express Warranties: Labor vs. Equipment

Two separate warranties typically apply to an HVAC installation:

1. The contractor's labor warranty — the contractor's own promise to correct workmanship issues for a stated period, commonly a year or more, though this is a business decision rather than a fixed statutory minimum for standard remodel or replacement work.
2. The manufacturer's equipment warranty — coverage on parts from the equipment manufacturer, which often requires the homeowner or contractor to register the equipment within a limited window after installation to receive the manufacturer's full parts-coverage term. Terms vary significantly by manufacturer and model, so a contractor should always state the manufacturer's actual published terms rather than a generic promise. A contractor who misrepresents manufacturer warranty terms to a homeowner risks both a contract dispute and a CSLB advertising or misrepresentation complaint.

The Right to Repair Act

Often called SB800, the Right to Repair Act (Civil Code §895 et seq.) applies to new residential construction sold on or after January 1, 2003. It sets detailed functionality standards for building components, including plumbing, mechanical, and HVAC systems, and requires a mandatory pre-litigation notice-and-opportunity-to-repair process before a homeowner can sue the builder over most construction defects. This statute is most relevant to a C-20 contractor working as part of a builder's new-home construction scope. For the far more common scenario of a C-20 contractor replacing or repairing HVAC equipment in an existing home for an individual homeowner, the common-law implied warranty of workmanlike performance described above, rather than the Right to Repair Act, is typically the operative standard.

Arbitration and Mediation Clauses

A residential contract of four units or fewer may include an arbitration clause, but B&P Code §7191 imposes strict formatting rules for it to be enforceable: the clause must carry the heading Arbitration of Disputes, be set in at least 10-point boldface type, or 8-point boldface red print, if printed, or in capital letters if typed, and must clearly notify the homeowner that initialing the clause means giving up the right to a jury trial and, absent a specific carve-out, the right to broad discovery and appeal. A clause that does not meet these formatting requirements may be unenforceable against the homeowner.

CSLB's Complaint, Mediation, and Arbitration Process

When a homeowner files a written complaint against a licensed contractor, the CSLB generally follows this sequence:

1. Intake and jurisdiction review — the CSLB confirms the complaint falls within its authority and notifies both the homeowner and the contractor, encouraging voluntary resolution.
2. Mediation — the CSLB attempts to mediate the dispute; straightforward cases often resolve in 30-60 days, while complex cases can take six months to a year or more.
3. Arbitration programs — the CSLB administers a mandatory arbitration program for disputes involving $25,000 or less in alleged damages, and a voluntary arbitration program for disputes between $25,000 and $50,000, which requires both parties to agree to use it. Arbitration awards are binding, and an unpaid award can be reduced to a civil judgment.
4. Investigation and discipline — if mediation and arbitration do not resolve a complaint involving a probable Contractors License Law violation, the CSLB refers the case to an Investigative Center, which can lead to a citation, accusation, or formal license discipline.

Separately, the CSLB's own disciplinary complaint deadlines under B&P Code §7091 matter for recordkeeping: a complaint alleging a patent, or readily observable, violation must be filed within four years, while a complaint alleging a latent structural defect has a ten-year filing window.
