Understanding the Claim
📜 Elements Claimant Must Prove
To succeed on a property damage negligence claim, the claimant must prove:
- Duty: You owed a duty of care to the claimant or their property
- Breach: You failed to exercise reasonable care in your work or actions
- Causation: Your breach actually and proximately caused the damage
- Damages: Measurable damage occurred that can be valued
For contractors, the claim may also be based on breach of contract if work was defective or didn't meet specifications.
Measure of Damages in California
| Type of Property | Measure of Damages | Citation |

💡 Betterment / Depreciation
Claimants are not entitled to "betterment" - they shouldn't profit from the damage. If repairs result in property better than before (new roof replacing 15-year-old roof), you may argue for depreciation offset. The goal is restoration to pre-damage condition, not improvement.
Available Defenses
No Causation / Damage Pre-Existed Strong
The damage existed before your work, or was caused by someone/something else. Your work didn't cause the claimed damage.
Evidence needed: Before/after photos, inspection reports, witness statements, evidence of pre-existing conditions, other possible causes
No Negligence / Standard of Care Met Strong
Your work met industry standards and was performed with reasonable care. The damage resulted from unforeseeable circumstances, not negligence.
Evidence needed: Industry standards, licensing, training records, inspection passes, expert opinion on reasonableness of methods
Contractual Limitation of Liability Strong
Your contract contains limitation of liability, indemnification clause, or exclusion of consequential damages that limits recovery.
Evidence needed: Signed contract with limitation provisions, evidence terms were negotiated or prominent
Comparative Fault Moderate
Claimant's own negligence contributed to the damage (improper maintenance, failure to disclose pre-existing issues, interference with work).
Evidence needed: Maintenance records, communications showing claimant's knowledge of issues, evidence of claimant's contributing actions
Third Party Responsible Moderate
Another contractor, the property owner, or third party caused or contributed to the damage.
Evidence needed: Evidence of other parties' work, subcontractor records, timeline showing damage occurred during another party's involvement
Excessive/Unsupported Damages Moderate
Claimed damages are inflated, unsupported by documentation, or include items not caused by your work. Claimant seeking betterment.
Evidence needed: Competing repair estimates, depreciation calculations, evidence claimed damage exceeds actual loss
Statute of Limitations Expired Situational
Property damage claims have 3-year SOL (CCP 338). For construction defects, special rules under CCP 337.1 and 337.15 may apply (4 years from completion for patent defects, 10 years for latent).
Evidence needed: Project completion date, date damage discovered, date claim filed
Failure to Mitigate Situational
Claimant failed to take reasonable steps to prevent additional damage after initial incident (didn't shut off water, didn't cover exposed area, delayed repairs).
Evidence needed: Timeline of events, evidence showing claimant's delay or inaction increased damages
