General liability is the first commercial policy most Maryland businesses buy, and it is usually bought under pressure: a general contractor in Clarksburg will not let your crew on site without a certificate, a Bethesda landlord will not hand over keys until the lease insurance clause is satisfied, the Maryland Home Improvement Commission wants proof of coverage before it issues your license, or a new client in Rockville sends over a master agreement with an insurance schedule on page nine. The policy itself is straightforward. It pays when someone outside your company says your business injured them or damaged their property, and it pays the lawyers whether or not the claim has merit.
What is less straightforward is matching the policy to what the other party actually asked for. Limits, additional insured endorsements, waivers, primary wording and completed operations coverage are where certificates get rejected and start dates slip. Terrapin has been placing general liability for Montgomery County businesses since 2011, from one-person contractors in Germantown to multi-location operations along I-270, and we read the contract before we quote so the paper matches the requirement the first time.

What general liability insurance covers: premises, operations, products and completed work
A commercial general liability policy responds to claims from third parties, meaning people and businesses other than you and your employees. The standard form breaks the coverage into a few buckets.
- Premises liability. A customer slips on a wet floor in your Silver Spring showroom, a delivery driver trips on your loading dock, a visitor is hurt in your Gaithersburg office. The policy pays their medical bills and damages and defends you.
- Operations liability. Injury or damage you cause while working away from your premises. A painter’s ladder goes through a client’s window; a landscaper’s mower throws a stone into a parked car.
- Products liability. Something you sell, manufacture or distribute injures someone or damages property after it leaves your hands.
- Completed operations. Work you finished months ago fails and causes damage: a deck you built collapses, a plumbing connection leaks into the unit below. For contractors this is often the largest exposure on the policy.
- Personal and advertising injury. Libel, slander, copyright infringement in your advertising, wrongful eviction and similar non-physical offenses.
- Medical payments. A small no-fault limit that pays a visitor’s medical bills quickly, before anyone argues about liability.
Who needs general liability insurance in Maryland
Maryland does not have a general statute requiring GL the way it requires workers compensation, but in practice the requirement comes from the people you do business with.
- Home improvement contractors. The Maryland Home Improvement Commission requires proof of general liability insurance to issue and renew an MHIC license. Remodelers, roofers, painters, deck builders, flooring installers and handymen in Montgomery County all run into this.
- Commercial tenants. Nearly every commercial lease in Rockville, Bethesda or Silver Spring requires the tenant to carry GL naming the landlord and often the property manager as additional insureds, with specified limits.
- Subcontractors. General contractors require a certificate before you start and usually want additional insured status, a waiver of subrogation and primary wording.
- Service businesses with client contracts. Consultants, IT firms, cleaning companies and staffing agencies routinely find GL in the insurance schedule of a master service agreement, including federal subcontracts across the DC metro.
- Anyone with foot traffic. Retailers, restaurants, salons, gyms and medical offices carry GL because a single premises injury claim can exceed years of profit.
- Vendors and event participants. Farmers markets, festivals and county facilities commonly require a certificate from each vendor.
What general liability insurance does not cover
The most expensive misunderstandings happen when a business assumes GL is a catch-all. It is not. These exposures are excluded and need their own policies.
- Professional errors and omissions. If a client says your advice, design, code or report cost them money, that is a professional liability claim. GL excludes it outright. See professional liability insurance.
- Injuries to your own employees. GL carves out employee injuries entirely; that is what workers compensation is for.
- Vehicles. Anything arising from the use of an auto is excluded. Your truck, your employee’s car on a work errand, a rented van all belong on a commercial auto policy.
- Your own property. GL pays for damage to other people’s property. Your tools, inventory, equipment and building need commercial property coverage or a BOP.
- Your own faulty work. If you have to tear out and redo a job, the policy does not pay for the redo; it pays for the resulting damage to other property.
- Data breaches, intentional acts, pollution, and employment disputes. Each is excluded or sharply limited and is addressed by cyber, EPLI or specialty forms.
General liability limits: why 1M/2M is the most commonly requested
A GL policy carries several limits, and contracts specify them in a particular order. The per-occurrence limit is the most the policy pays for any one incident. The general aggregate is the most it pays for all incidents in a policy year. There is a separate products-completed operations aggregate, plus sublimits for personal and advertising injury, damage to rented premises and medical payments.
The combination you will see most often in Maryland leases, subcontract agreements and vendor contracts is $1,000,000 per occurrence with a $2,000,000 general aggregate, commonly written as 1M/2M. It is the standard carriers’ default structure, so it is what contract drafters reach for. Some contracts, especially with larger general contractors, government entities and institutional landlords, ask for more, which is usually solved with a commercial umbrella rather than a higher primary limit. Smaller limits exist and cost less, but if a contract requires 1M/2M and you carry 500K/1M, the certificate will be rejected and you will be buying the upgrade mid-term anyway. We quote the limit your contracts require and show you the cost of the next step up.
Additional insureds, waivers of subrogation and primary wording
These three phrases appear in almost every insurance clause a Montgomery County business signs, and they are the reason certificates get bounced.
An additional insured endorsement extends your coverage to the other party, typically a landlord or general contractor, for claims arising out of your work or your use of their premises. Contracts often name the specific endorsement forms they want, and may require that the status apply to both ongoing operations and completed operations. Some carriers include blanket additional insured wording that applies automatically when a written contract requires it; others charge per endorsement. A waiver of subrogation means your carrier agrees not to pursue the other party to recover what it paid on your claim, even if they were partly at fault. Primary and non-contributory wording says your policy pays first and does not ask the other party’s insurer to share.
None of these are created by a certificate. They have to be on the policy. When you send us a lease or subcontract, we check the clause against the policy forms before we bind, and we tell you which carriers include the wording at no charge.
Certificates of insurance: turnaround and what we need from you
Once your GL is in force, certificates are an ongoing service, not a one-time event. A typical contractor in Germantown or Gaithersburg might need a dozen a year as new jobs start; a consultant might need one per client. Routine certificates showing your limits and policy dates go out the same business day, usually within an hour or two of the request. Certificates that require adding a new additional insured or confirming specific endorsement forms can take a little longer because the policy may need an endorsement issued first, though carriers with blanket wording make this nearly instant.
To issue quickly we need the exact legal name and mailing address of the certificate holder, whether they need to be an additional insured or just a holder, the project address or description if applicable, and a copy of the insurance requirements if the contract has them. Send the clause, not a summary; the details matter. We also set up recurring holders so your landlord and standing clients receive updated certificates automatically at renewal.

Which carriers write general liability for Maryland businesses
No single carrier is right for every business, which is the whole argument for an independent agency. Erie Insurance is a strong fit for established small and mid-size Maryland businesses, contractors, retailers and offices, usually through its ErieSecure Business package, and is consistently ranked at the top of J.D. Power claims studies. MGT writes BOPs, standalone GL and packages across professional services, retail, food service and contractor classes. ERGO Next is a digital-first market that quotes standalone GL quickly for consultants, contractors and self-employed professionals in MD, DC and VA. Travelers and Chubb come into play for larger, more complex or professional accounts. When a risk falls outside the admitted market, we have wholesale access through FirstChoice, RT Specialty, AmWins, CRC and Burns & Wilcox. See the full carrier list.
