Business interruption insurance: the coverage that saves companies after disaster

I've been insuring Bay Area businesses for over 50 years, and there's one coverage I bring up in almost every commercial review that gets the same reaction: a blank stare followed by "I think I have that... somewhere."

Business interruption insurance. Also called business income coverage. It's the policy that pays your bills when your business can't.

And most small business owners either don't have it, don't understand it, or have it set at a limit that was last reviewed when gas was $3 a gallon.

What business interruption actually covers

Here's the scenario. You own a restaurant on Laurel Street in San Carlos. A kitchen fire breaks out on a Friday night. Nobody's hurt — thank God — but the damage is significant. The health department shuts you down. The contractor says eight months minimum for the rebuild.

Your property insurance covers the physical damage — the walls, the equipment, the build-out. That's the part people understand.

But who pays your rent while you're closed? Who covers your payroll for the staff you want to keep? Who replaces the revenue you're not earning for the next eight months?

That's business interruption insurance. It covers the income you would have earned if the loss hadn't happened, plus the continuing expenses you still have to pay — rent, loan payments, utilities, payroll for key employees, taxes.

Without it, you're writing those checks out of your own pocket. For eight months. While earning nothing.

How it works

Business interruption coverage is typically included in a Business Owners Policy (BOP) or added as an endorsement to a commercial property policy. It kicks in when a covered peril — fire, burst pipe, vandalism, windstorm — causes physical damage to your property that forces you to suspend operations.

The key components:

The restoration period is critical. Most policies pay from the date of the loss until the property is repaired and you've returned to normal operations — or until your coverage limit runs out, whichever comes first.

The mistakes I see over and over

Mistake #1: The limit is too low

This is the most common problem. A business owner set their business income limit five years ago based on revenue at the time. Revenue has grown 40% since then. The limit hasn't.

Or worse — they picked a round number that sounded reasonable without actually calculating their exposure. "$100,000 should be enough." Should it? If your monthly fixed costs are $25,000 and a rebuild takes 8 months, you need $200,000 minimum — and that's before lost profit.

How to set the right limit: Add up your projected annual revenue, subtract expenses that would stop during a closure (like cost of goods sold), and add your fixed continuing expenses. That's your annual business income exposure. Then consider how long a worst-case rebuild would take.

Mistake #2: No coverage for key employees

If you close for six months and your best people find other jobs, what does that cost you when you reopen? Training new staff, lost institutional knowledge, slower ramp-up. Some business interruption policies include coverage for ordinary payroll — the wages of employees you want to retain during the shutdown even though they're not working.

If your policy excludes ordinary payroll, you have a hard choice during a loss: keep paying people with no income, or let them go and start over when you reopen.

Mistake #3: Ignoring the waiting period

Most business interruption policies have a waiting period — typically 72 hours — before coverage kicks in. That means the first three days of lost income are on you. For some businesses, that's manageable. For others — especially restaurants, retail, and service businesses with high daily revenue — three days is significant.

Know your waiting period. Factor it into your planning.

Mistake #4: Assuming all perils are covered

Business interruption only responds when the underlying property coverage responds. If the physical damage was caused by a peril that's excluded from your property policy — flood, earthquake, pandemic — your business interruption coverage won't pay either.

This is a big deal in the Bay Area. If an earthquake damages your building and shuts you down for six months, standard business interruption does nothing. You need separate earthquake business interruption coverage for that.

Same with flood. Surface water shuts down your operation? Standard BI won't cover it unless you have a flood policy with business income coverage.

The Bay Area reality

On the Peninsula, commercial rents are high, construction timelines are long, and permit processes are slow. A rebuild that might take four months in other parts of the country can take eight to twelve months here.

That means your business interruption exposure is bigger than you think. I've seen clients shocked when I walk through the math:

That's not a hypothetical. That's a real scenario for a mid-size Bay Area business. And I've reviewed policies where the business income limit was set at $100,000.

Civil authority and dependent properties

Two additional coverages worth knowing about:

Civil authority coverage — pays when a government order prevents you from accessing your property, even if your property wasn't directly damaged. Example: a fire in the building next door forces an evacuation of your building for two weeks.

Dependent property coverage — pays when damage to a supplier or key customer's property interrupts your business. Example: your sole supplier's warehouse burns down and you can't get materials for three months.

Neither of these is automatic on every policy. Ask your agent whether they're included and at what limits.

When to call your agent

Review your business interruption coverage when:

Any of those is a five-minute conversation that could save you from a six-figure gap.

The bottom line

Business interruption insurance isn't glamorous. Nobody gets excited about it at renewal time. But it's the coverage that determines whether a fire or a disaster is a recoverable setback or the end of your business.

The physical damage gets repaired. Insurance handles that part. The question is: who pays your bills while the repairs are happening?

If you don't have a good answer to that question, send me your current policy. I'll look at the business income limits and tell you — honestly — whether they're enough. Five minutes now could make a half-million-dollar difference later.
