Can My Business Recover Lost Profits After Property or Equipment Damage in California?

California recognizes that economic losses caused by wrongful conduct can extend beyond the immediate cost of repairing damaged property.

Civil Code section 3333 generally permits compensation for detriment proximately caused by a wrongful act not arising from contract.¹

Where a claim arises from breach of contract, Civil Code section 3300 supplies a different damages framework, generally compensating for losses proximately caused by the breach or that would ordinarily be expected to result from it. Contract damages must also be clearly ascertainable in their nature and origin under Civil Code section 3301.¹

Lost profits may be recoverable under either framework when the applicable legal requirements are satisfied.

The California Supreme Court recognized this principle in Grupe v. Glick (1945) 26 Cal.2d 680, explaining that interruption of an established business can support recovery of profits that otherwise would have been earned when the evidence establishes their occurrence and extent with reasonable certainty. The case involved defective oil re-refining machines and contractual warranty damages; it does not make every property-damage interruption compensable.²

The rule does not make every interruption compensable.

The business must first establish a viable legal claim against the responsible party.

For example, if a transportation company's negligence damages commercial equipment, the resulting interruption may support a property-damage claim that includes properly proven lost profits.

If the alleged loss arises from a contractual relationship, the agreement and applicable contract-damages rules may impose additional limitations.

A financial loss is not, by itself, proof that another party is legally responsible for it.

This is one of the most important distinctions in a business-interruption claim.

Suppose a business cannot operate normally for several weeks.

The owner reviews prior sales and concludes that substantial revenue was lost.

That figure may provide a starting point.

But California generally measures lost business profits by net profits rather than gross revenue.

Judicial Council Civil Jury Instruction CACI No. 3903N directs that lost profits be determined by identifying the gross amount the business would have received but for the defendant's conduct and subtracting the expenses it would have incurred to earn that amount.³

Those expenses may include labor, materials, rent, and other appropriate costs, depending on the facts.

The practical distinction is straightforward.

If a business could not complete an order, it may have lost the customer's payment. But it may also have avoided purchasing materials, paying subcontractors, or incurring other expenses associated with fulfilling that order.

A lost-profits calculation must account for the relevant costs.

Otherwise, a business risks seeking compensation for revenue it never would have retained as profit.

The strongest evidence generally comes from the business's actual financial performance.

Useful records may include:

These documents can help establish the difference between what the business probably would have earned without the interruption and what it actually earned.

Historical performance is particularly useful because it provides a measurable baseline.

But historical revenue alone may not be sufficient.

A business should also consider whether the relevant period involved unusual seasonal demand, an anticipated expansion, customer losses unrelated to the incident, changes in market conditions, or other factors affecting expected profitability.

The objective is to isolate the economic effect of the property damage rather than attribute every unfavorable financial result to the defendant.

The governing standard does not demand an exact reconstruction of a financial future that never occurred.

But it does require more than speculation.

In Sargon Enterprises, Inc. v. University of Southern California (2012) 55 Cal.4th 747, the California Supreme Court examined a substantial lost-profits claim arising from a university's breach of a clinical-testing contract.

The plaintiff's expert projected extraordinary future commercial success by comparing the company to much larger competitors.

The Supreme Court reversed the Court of Appeal and held that the trial court acted within its discretion in excluding the speculative lost-profits opinion.⁴

The decision reinforces two principles.

First, lost profits do not need to be established with mathematical precision.

Second, expert testimony must be grounded in reliable evidence and a rational methodology.

A financial expert cannot transform an unsupported business forecast into recoverable damages simply by presenting a sophisticated calculation.

For businesses considering litigation, the lesson is important:

The credibility of the underlying assumptions often matters more than the complexity of the damages model.

An established business generally has an evidentiary advantage.

Its prior revenue, operating expenses, customer history, and profitability may provide a reasonable basis for estimating what would have occurred without the interruption.

A newer business may not have that record.

California courts distinguish between established businesses and ventures that have not yet demonstrated reliable operating results.

That distinction does not categorically prohibit a new business from recovering lost profits.

But the evidence must still establish the claimed profits with reasonable certainty.

In some circumstances, reliable industry data, comparable business performance, existing customer contracts, or other objective evidence may support the projection.

The weaker the operating history, the more carefully those assumptions must be examined.

The published decision Kids' Universe v. In2Labs (2002) 95 Cal.App.4th 870 is particularly relevant to businesses dealing with property damage.

Kids' Universe operated a retail store in Beverly Hills.

An employee of an upstairs tenant left water running overnight, causing flooding that damaged the store and interrupted its operations.

The resulting damage affected inventory and business activities.

The plaintiffs later pursued a negligence claim seeking anticipated profits from an online retail business they contended they would have launched successfully but for the flooding.

The problem was proof.

Although the plaintiffs believed their planned online venture could have developed into a major commercial operation, the Court of Appeal concluded that the projected profits were too speculative.

The court affirmed summary judgment on the cause of action, whose only claimed damages were the anticipated online-business profits.⁵

The decision did not establish that flooding-related business losses are categorically unrecoverable.

Instead, it illustrates why a business cannot recover speculative profits from an anticipated venture merely because a defendant caused actual physical damage.

There must be a sufficiently reliable connection between the wrongful conduct and the claimed financial result.

Causation is separate from the calculation of damages.

A business may demonstrate that revenue declined after property damage.

But the defendant may argue that the decline resulted from unrelated factors.

For example, sales may already have been falling. A major customer may have canceled its contract for independent reasons. Demand may have weakened across the industry.

A proper damages analysis should consider those possibilities.

The business should be prepared to establish how the damaged property affected operations and why that operational disruption caused a measurable loss of profits.

That may require showing that:

The evidence should support a causal explanation rather than merely show that the damage and lost revenue occurred during the same period.

Potentially, because the two categories compensate for different losses.

Repair or replacement costs concern the damaged property.

Lost profits concern earnings the business would otherwise have retained from operations.

For example, repairing damaged commercial equipment may restore the physical asset without compensating the company for profitable work it could not perform during the interruption.

California law permits recovery of different categories of compensable economic harm when the relevant requirements are met.

But the damages must not overlap.

The analysis may also involve loss-of-use damages.

For certain personal property, CACI No. 3903M measures loss of use by reference to the reasonable cost of renting comparable property for the time reasonably necessary to repair or replace it.³

For real property, CACI No. 3903G addresses compensable loss of use through a reasonable rental-value measure.³

Those categories should be distinguished from lost profits.

A claimant should not assume it can recover multiple overlapping measures for the same period and economic injury.

The damages must be organized so that each component compensates for a distinct, legally recoverable loss.

California law expects an injured party to take reasonable steps to avoid unnecessary additional damage.

This is commonly called mitigation of damages.

CACI No. 3931 addresses mitigation in property-damage cases.³

A defendant may seek to reduce damages by proving that the plaintiff could have avoided particular losses through reasonable efforts or expenditures.

Reasonableness is evaluated in light of the circumstances confronting the injured party at the time.

The law does not necessarily require a business to take extraordinary risks or incur disproportionate expenses.

Reasonable mitigation efforts might include renting temporary equipment, moving operations to another location, outsourcing part of the work, or arranging emergency repairs.

Whether those measures were practical depends on their availability, cost, timing, and effect on operations.

Reasonable expenses incurred to reduce the harm may themselves be compensable in appropriate circumstances.

The key is to document both the measures considered and the steps actually taken.

Insurance coverage and third-party liability are separate questions.

A commercial property policy may provide coverage for damaged equipment, inventory, or a building.

Business-interruption coverage may also exist, depending on the policy.

The California Department of Insurance explains that business-interruption insurance is optional coverage and generally depends on a covered cause of loss, applicable policy conditions, and the nature of the interruption. CDI states that coverage typically requires direct physical property loss leading to interruption; the actual policy terms, exclusions, limits, deductibles, and restoration provisions matter.⁶

Not every commercial property policy includes it.

And the availability of business-interruption insurance does not automatically determine the scope of a negligence claim against the responsible third party.

A business may therefore need to analyze two distinct avenues of recovery:

First-party insurance: What benefits does the business's own policy provide?

Third-party liability: What damages can the business establish against the person or company legally responsible for the loss?

Those avenues may involve different standards, evidence, exclusions, and procedural requirements.

Any insurance payments, settlement agreements, releases, and potential subrogation rights should be reviewed to avoid overlooking their effect on the remaining claims.

The compensable period is not necessarily identical to the time required to complete physical repairs.

Repairs may finish before the business can fully resume operations.

Alternatively, the business may be able to resume profitable work using substitute equipment or another facility before repairs are complete.

The relevant period depends on causation, reasonable mitigation, and the evidence.

A business should therefore document the dates of the incident, operational interruption, mitigation measures, repair or replacement, and restoration of business capacity.

Claims for losses extending substantially beyond physical restoration generally require particular attention.

The longer the claimed interruption, the more important it becomes to distinguish losses caused by the original event from later market conditions, business decisions, or unrelated developments.

There is no universal recovery period applicable to every California business-interruption damages claim.

The filing deadline depends on the underlying legal theory.

For ordinary injury to real property, Code of Civil Procedure section 338(b) generally provides a three-year limitations period.⁷

Section 338(c)(1) generally provides three years for injury to goods or other personal property.⁷

A claim founded on a written contract may instead be governed by the general four-year limitations period in section 337.⁸

Those are general rules, not an exhaustive statement of every applicable deadline.

Other statutes, contractual provisions, government-claim requirements, accrual rules, and exceptions may affect a particular claim.

Importantly, a claimed loss of profits does not necessarily create an independent limitations period separate from the underlying legal cause of action.

A business should identify the applicable claim and deadline before allowing negotiations or insurance discussions to continue indefinitely.

Preserving the physical evidence is only part of preparing the claim.

The financial record matters just as much.

Document the damage, the affected equipment or facility, the condition of the property before the incident, and the steps required to restore operations.

At the same time, preserve contemporaneous financial records that explain how the business was performing before the interruption.

Maintain separate records of repair expenses, replacement equipment, mitigation costs, canceled orders, delayed work, and the dates on which business operations were restricted.

If the claim is substantial, an independent financial expert may be useful to evaluate the claimed lost profits and distinguish them from unrelated financial changes.

The objective is to create a reliable record of what happened—not to construct an optimistic forecast after the dispute begins.

When another party damages business property, the cost of repair may represent only part of the economic harm.

California law recognizes that an established business may lose profits when its operations are wrongfully interrupted.

But recovery is not automatic.

A legally supportable claim generally requires proof of the responsible party's liability, the interruption caused by that conduct, and profits that would have been earned with reasonable certainty.

The strongest analysis connects the physical damage to a measurable interruption, the interruption to identifiable business losses, and those losses to reliable financial evidence.

That connection is what distinguishes a credible lost-profits claim from a speculative one.
