What Is a Business Owner's Policy (BOP)? A California Guide
A business owner's policy (BOP) is a package policy that bundles commercial property, business income and general liability into a single contract for small and mid-sized businesses. The California Department of Insurance describes it as "a combination commercial policy that covers property, general liability and business interruption," designed for small "main street" businesses like hardware stores, barbershops, accountants' offices and small apartment buildings.
For a business that qualifies, a BOP is usually the simplest way to put the core coverage in place. It isn't complete coverage, though. It leaves out workers' comp, commercial auto and professional liability, and qualifying depends on the carrier. If you're putting together small business insurance for the first time, this guide explains what a BOP includes, who qualifies, what it leaves out and when a different structure works better.
What a BOP bundles
Most BOPs are built on, or modeled after, the Insurance Services Office (ISO) Businessowners Coverage Form, BP 00 03. ISO calls it "a self-contained package policy offering broad property and liability coverage designed for small and midsize 'Main Street' businesses." Carriers can use the ISO form or file their own, so treat the details below as the typical starting point and check your own policy wording.
Section I: Property
Building, if you own it, and business personal property: furniture, equipment, inventory, tenant improvements.
Business income. Under ISO's form, this covers the actual loss of income during the period of restoration that occurs within 12 consecutive months after the physical loss. It's included in addition to the property limits. See our guide to business income insurance.
Extended business income. Up to an additional 60 days of income coverage after you reopen, under ISO's standard form.
Extra expense. The extra cost of staying open or reopening faster.
Built-in additional coverages. ISO's form includes items such as debris removal, civil authority, forgery or alteration (up to $2,500), money orders and counterfeit money (up to $1,000), increased cost of construction (up to $10,000 per building), electronic data (a $10,000 aggregate), and valuable papers and accounts receivable (up to $10,000 each on premises).
ISO's BOP settles most property losses on a replacement cost basis, subject to an 80% insurance-to-value requirement that can be waived by endorsement. For how property coverage works in more detail, read what commercial property insurance covers.
Section II: Liability
ISO says the BOP's liability section is designed to cover sums you become legally obligated to pay because of bodily injury, property damage, or personal and advertising injury. Defense costs are paid outside the limits. In practice it does the same job as a standalone general liability insurance policy.
Standard ISO BOP liability details:
Feature | ISO standard BOP |
Basic liability limit | $300,000 per occurrence, increasable to $500,000, $1M or $2M |
General aggregate | Twice the per-occurrence limit |
Products-completed operations aggregate | Separate, also twice the per-occurrence limit |
Medical expenses | $5,000 per person, increasable to $10,000 |
Damage to premises rented to you | $50,000, higher available |
Defense costs | Outside the limits |
Carriers that use their own forms set their own limit options, so check the declarations page rather than assuming.
Deductibles
ISO's base property deductible is $500, with optional fixed deductibles from $250 up to $10,000. Those apply per occurrence and separately at each location that sustains damage. The deductible you choose is one of the easiest levers on price. Our guide on how to lower your premium covers the trade-off.

Who qualifies for a BOP
Eligibility is set by each carrier. Size, revenue and class of business all matter, and a business one carrier declines can be a routine BOP for another. The CDI notes that BOPs are written under "strict underwriting guidelines including maximum allowable square footage."
As a reference point, here is how ISO's standard program sets eligibility:
Business type | ISO standard eligibility (as of Feb 2025) |
Most eligible classes | Up to 35,000 sq ft total floor area and $6,000,000 annual gross sales per location |
Offices | Up to 100,000 sq ft and 6 stories |
Contractors | Payroll no more than $300,000 a year; no exterior work above 3 stories; subcontracted work no more than 10% of gross sales; no renting equipment to others |
Retail | On-site repair allowed; off-site repair up to 25% of total annual sales |
Internet retailers | No more than 10% direct sales; no direct importing of products for retail sale |
Processing and service | No more than 25% of gross sales from off-premises operations |
Restaurants | Generally up to 7,500 sq ft, seating caps by type, and limits on alcohol as a share of sales |
Wholesale and distribution | No more than 25% of sales from retail, and no more than 25% of floor area open to the public |
Apartments | No square-foot limit |
ISO's eligible categories include apartments, auto service, offices (including medical offices), retail and internet retail, light manufacturing, hotels and motels, processing and service businesses, restaurants, self-storage, wholesale and distribution, and contractors.
Carriers then add their own rules. Some decline certain trades outright. Others cap the number of employees, the building's age, its construction type or its wildfire exposure. In California, wildfire exposure and building age are common reasons a BOP application gets declined, so it helps to have more than one carrier to try.
What a BOP does not cover
This is where owners get caught. A BOP is a property-and-liability package. Several major exposures sit outside it entirely.
Workers' compensation
A BOP does not cover injuries to your own employees. In California, Labor Code §3700 requires every employer to secure workers' compensation, either through an authorized insurer or a certificate of consent to self-insure. That is a separate policy. Our workers' comp guide covers how it works.
Commercial auto
Vehicles your business owns are not covered by the BOP. Personal auto policies don't fill the gap reliably either. The CDI has said that "personal automobile policies do not typically provide coverage for vehicles used for commercial purposes." Read when you need commercial auto insurance.
There is one partial fix inside the BOP. ISO offers a hired auto and non-owned auto liability endorsement, which covers liability when employees use rented cars or their own vehicles on company business. It does not cover vehicles you own. See hired and non-owned auto.
Professional liability
The standard BOP excludes professional services, meaning claims that your advice, design, or professional work caused someone a financial loss. ISO offers professional liability endorsements for a short list of classes, including barbers and beauty salons, pharmacists, veterinarians, opticians and printers. Most professionals need a separate E&O policy. The difference is explained in general liability vs professional liability.
Other common gaps
Earthquake and flood. Under ISO's program both are available only by endorsement, and whether a carrier offers them on a BOP varies.
The BOP has limited electronic data coverage. A data breach or ransomware event needs real cyber insurance.
Employment claims. Wrongful termination, harassment and discrimination claims fall under employment practices liability (EPLI), not the BOP.
Liquor liability. Excluded unless endorsed. Restaurants and bars should ask specifically.
Equipment breakdown. In ISO's program it's an optional coverage, not automatic.
Common BOP endorsements
ISO's program lists a long menu of endorsements. These are the ones California small businesses ask about most:
Endorsement | What it does (typically) | Who usually needs it |
Hired and non-owned auto liability | Liability for rented and employee-owned vehicles used on business | Any business whose staff drive for errands, sales calls or deliveries |
Additional insured (several versions) | Extends liability coverage to a landlord, client or general contractor | Tenants, contractors, vendors |
Waiver of subrogation | Waives the carrier's right to recover from a party you've contracted with | Anyone signing leases or service contracts that require it |
Primary and noncontributory | Makes your coverage respond first for an additional insured | Contractors and vendors with contract requirements |
Equipment breakdown | Mechanical or electrical breakdown of equipment | Restaurants, offices with server rooms, manufacturers |
Spoilage | Perishable stock lost to refrigeration breakdown | Food service, grocery, florists |
Employee dishonesty | Theft by your own employees | Any business handling cash or inventory |
Ordinance or law | Code-upgrade costs and the value of undamaged portions that must be demolished | Owners of older buildings |
Contractors' installation, tools and equipment | Tools and materials in transit or at job sites | Trades contractors |
Liquor liability | Removes or narrows the liquor exclusion | Restaurants, caterers, event venues |
Contracts drive many of these. Before you sign a lease or a service agreement, send the insurance section to your agent so the endorsements are in place before the certificate is requested.
When a BOP doesn't fit
A BOP is designed for a specific profile. It's usually the wrong tool when:
You're too big. You're above the carrier's square-footage, revenue or payroll limits. Separate commercial property and general liability policies, often written together as a commercial package, give more room.
Your class is excluded. Higher-hazard trades, many manufacturers, bars with heavy liquor sales, and some contractors fall outside BOP programs.
You don't own much property. Consultants and other service businesses with little equipment may only need general liability plus professional liability. See BOP vs general liability for the side-by-side comparison.
You need higher limits than the BOP allows. Large contracts may require limits or terms that a BOP can't carry. An umbrella can sometimes bridge this.
Your property is hard to place. Buildings in high wildfire-risk areas, older construction, or vacant property may be declined by BOP carriers and need specialty or surplus lines markets.
You work from home. A home-based business may be better served by a homeowners endorsement or a small BOP depending on size. Read home-based business insurance.
How BOP premiums are set
Carriers price a BOP based on the business class, location, building construction and age, the property limits you choose, your revenue or payroll, deductibles, claims history and any endorsements. We don't publish average BOP prices. They vary too much by class and location to be meaningful, and the only reliable number is a quote on your actual exposures. Our guide on how to lower your premium covers the factors you can control.
FAQs
What does a business owner's policy cover?
A BOP typically bundles commercial property (building and business personal property), business income and extra expense, and general liability for bodily injury, property damage and personal and advertising injury. Exact coverage depends on the carrier's form, so read your policy wording.
What is not covered by a BOP?
Standard BOPs do not include workers' compensation, commercial auto for vehicles you own, professional liability (with narrow exceptions), cyber, employment practices liability, earthquake or flood. Each needs its own policy or endorsement.
Who is eligible for a business owner's policy?
Each carrier sets its own rules. Under ISO's standard program, most eligible businesses are limited to 35,000 square feet and $6 million in annual gross sales per location, with special rules for contractors, restaurants, offices and others.
Is a BOP required in California?
No California law requires a BOP. Workers' comp is required for employers under Labor Code §3700. Landlords, lenders and clients often require property and liability coverage by contract, and a BOP is a common way to meet that.
Is a BOP cheaper than buying general liability and property separately?
Often, for businesses that qualify, because the carrier packages the coverage. That isn't guaranteed, and a BOP's limits and terms may not suit every business. Comparing both structures is worth doing.
Can I add hired and non-owned auto to a BOP?
Usually yes. ISO's program includes a hired auto and non-owned auto liability endorsement, and most carriers offer something similar. It does not cover vehicles your business owns.
