General Liability Insurance
Understand what general liability insurance is for, from customer injuries to damage to someone else’s property, and what to tell us about your operations.
Protection for everyday business risks
General liability is the policy for claims that your business hurt someone or damaged their property: a customer who trips over a cord in your shop, a crew that cracks a client’s countertop, a delivery that dents a lobby door. It also pays to defend a covered claim.
How much does general liability insurance cost?
General liability starts around $250 a year at the low end of published premium data from national small-business insurers, and the typical California buyer in that data pays about $42 a month, close to $500 a year, as of 2026. Those figures describe sole proprietors and very small firms, most with fewer than five employees, buying the standard $1 million per occurrence and $2 million aggregate limits. Established businesses with staff, larger sales or higher-risk work commonly pay well above that median, and the published spread passes $3,000 a year. Read them as published industry data, not a Mithril1 quote.
Insurers rate this coverage on an exposure base tied to the class of work: gross sales for shops and restaurants, payroll for contractors and floor area for some premises. One published illustration applies a rate of $1.85 per $1,000 of sales to a restaurant selling $1.2 million a year, so 1,200 × $1.85 comes to $2,220 before credits, debits or experience adjustments. Modeled benchmarks run higher than that median: one national rate-comparison site puts California general liability at about $92 a month for a sole proprietor, $190 for one to four employees, $526 for five to nine and $1,445 for 10 to 19.
Your figure goes up with more employees or payroll in riskier classes; construction and contracting reach about $596 a month in that same California data for a crew of one to four. Past claims, limits above $1 million, a lower deductible and the additional insured, waiver of subrogation or primary and noncontributory wording that clients and landlords write into contracts push it higher as well. It comes in lower with a clean claims history, written safety and hiring practices, a higher deductible, a class code that matches the work you actually do, and, for eligible businesses with property to protect, liability packaged into a Business Owner’s Policy.

The general liability savings guide lists the steps a business controls, from class codes to subcontractor certificates.
When a contract asks for more than your general liability limit
Sooner or later, many growing businesses meet a lease, venue agreement or general contractor’s subcontract that names a per-occurrence limit higher than their general liability policy holds. Raising the base limit is one route. Another is a commercial umbrella, which sits above general liability and adds a further layer of limits once the underlying policy is exhausted.
An umbrella usually extends over commercial auto and employer’s liability as well, so one policy can lift several limits at once. Bring the contract wording when you ask, because some agreements expect the umbrella to follow the same additional insured terms as the general liability policy. The certificate of insurance guide explains how both layers appear on a certificate, and checking that before the job starts avoids a second request from the client.
Where customers, clients and contracts meet
Most businesses touch other people every day: a customer browsing your shop, a crew working inside a client’s building, a delivery dropped at someone’s office. That daily contact with the public is why general liability is so often the first policy an owner asks about.
Bring the insurance pages of your leases and client contracts, including any additional insured wording, and see how the contractor guide and the COI guide handle the paperwork that tends to come with them. Having the requirements in hand makes choosing limits much simpler.
Everyday situations this policy is built around
A customer slips on a wet entryway at a Walnut Creek retail shop. A painter’s ladder scratches the lobby floor of an Oakland office building. A product you sold is blamed for damaging someone’s property. These third-party injury and property damage situations are what general liability is designed for, and they show why the policy follows your operations as well as your address.
Many general liability forms also address personal and advertising injury, such as a claim that your marketing used someone else’s material or a complaint about something said in an ad. Ask how the policy you are considering treats it, especially if you advertise heavily or publish content online.
Per-occurrence and aggregate limits
Liability policies usually show two figures. The per-occurrence limit applies to any single claim, while the aggregate limit is the most the policy pays during its term. Leases and client contracts often name both, so read their requirements side by side with any quote you are weighing.
Ask about the deductible, too, and how defense costs relate to the limit. Comparing two quotes fairly means comparing the same limits, the same described operations and the same exclusions, not just the premium at the bottom of the page.
What to have ready for a general liability quote
The fastest conversations start with a clear picture of where your business meets the public, from customers and visitors to other people’s property in your care. Claims about professional advice belong with professional liability, and employee injuries with workers’ compensation. Pull these details together first, or work through our full quote checklist.
A few useful answers
Common questions
How does general liability differ from a BOP?
A BOP bundles general liability with commercial property coverage. General liability by itself does not provide the same property protection.
How can I insure the equipment my business owns?
Ask about commercial property coverage. A Business Owner’s Policy pairs general liability with commercial property coverage in one package.
How much liability coverage should I consider?
Many small businesses start at $1 million per occurrence and $2 million aggregate, the standard limits that many leases and client contracts ask for. A contract can set a higher floor, and our guide to how much general liability insurance you need walks through the choice.
Is general liability the same as commercial insurance?
General liability is one type of commercial insurance. A complete plan often adds commercial property, commercial auto, workers’ compensation or professional liability, chosen around the work you do.
Should I mention work I do at clients' locations?
Yes. The policy describes your business operations, not only your address, so include the services you perform at customer sites and events.
