1. What is Business Interruption Coverage?

Business Interruption Insurance (BI) compensates for lost income and fixed expenses when a covered event halts operations. It aims to restore your financial position as if no interruption occurred.

  • Replaces lost profit and ongoing costs such as rent, payroll, and utilities.
  • Usually added to property insurance or included in a Business Owners Policy (BOP).
  • May include extra expense coverage for relocation or accelerated reopening.

2. Key Triggers (Fire, Disaster, Supply Chain)

To activate BI coverage, there must be physical damage from a covered peril. In California, triggers include:

  • Fire or smoke damage halting operations.
  • Wildfire and utility shutdowns—covered under civil-authority extensions.
  • Earthquake or flood: excluded by default, add via separate or parametric cover.
  • Supply-chain disruption via contingent BI endorsements.
  • Government closure orders if nearby damage prevents access.


3. How Premiums Are Calculated

Premiums depend on projected income and exposure. Common 2025 rating factors include:

Factor Impact Example
Annual Revenue Higher revenue = higher potential loss. $2M × $1.50/$1K = $3,000 premium.
Business Type Manufacturing > retail > office risk. Auto shop ≈ +30% vs accountant.
Location Wildfire/flood zones rated higher. Ventura > Sacramento.
Indemnity Period 12 vs 24 months = +25–30% cost. Longer = higher premium.
Waiting Period 72h deductible lowers cost. 24h = higher rate.

4. Ways to Reduce Cost

  • Continuity planning: 5–10% discount for documented recovery plans.
  • Layered coverage: Pair property + parametric wildfire/quake policies.
  • Higher deductibles: Extending waiting period reduces cost.
  • Bundling: BI under a BOP is cheaper than standalone.
  • Loss prevention: Fire suppression and backup systems lower risk ratings.

5. Claim Readiness Tips

  • Keep updated financials and expense logs.
  • Store off-site backups of insurance and vendor data.
  • Track extra costs (rentals, overtime) separately for reimbursement.
  • Log downtime accurately to align with waiting-period requirements.
  • Contact your adjuster early to confirm restoration timelines.

Frequently Asked Questions

Is business interruption included automatically?

No. It’s usually an add-on to property or BOP coverage. Always verify your policy’s “Business Income” limit and waiting-period terms.

Does BI insurance cover pandemics?

Generally no — standard policies exclude communicable diseases unless specially endorsed. Some carriers now offer limited parametric pandemic riders.

How long does BI coverage last?

Typically 12 months; optional extensions to 18–24 months are available for complex rebuilds. Longer indemnity periods raise premiums proportionally.

  • Typical 2025 BI cost: $500–$3,000 per $1M revenue in California.
  • Physical loss triggers coverage; pandemics remain excluded.
  • Rates scale with revenue, risk zone, and indemnity period.
