There is a whole economy operating out of spare bedrooms in Montgomery County. Federal contractors who went independent after a reorg. Grant writers and proposal consultants in Rockville. Tutors and college-essay coaches in Potomac and Bethesda. Bookkeepers, therapists, IT consultants, general contractors who keep tools in the garage, and a steady stream of Etsy and cottage-food sellers working out of Silver Spring and Gaithersburg kitchens.

Almost all of them have homeowners or renters insurance. Almost none of them have insurance that responds when something goes wrong with the business part.

That gap is not a technicality. It is written into the policy on purpose. Here is what your homeowners policy quietly excludes, and the six places a home-based Montgomery County business is most likely to get caught.

1. Your Business Property Has a Sublimit You've Never Read

A standard Maryland HO-3 covers your personal belongings generously and your business belongings barely. Typical policies cap business personal property at roughly $2,500 while it's at the house, and often just a few hundred dollars once it leaves.

Do the arithmetic on what's actually in the room. A photographer's two bodies and three lenses. A contractor's tools in the garage. A consultant's laptop, monitors, dock and printer. A baker's commercial mixer and racks. A therapist's furnished office. It is remarkably easy to be sitting on $15,000 of business equipment protected by a $2,500 limit — and the sublimit applies the same way whether the cause is a Montgomery County thunderstorm, a burst pipe or a break-in.

2. Business Liability Is Excluded Outright

This is the one that costs real money. The liability section of a homeowners policy contains a business pursuits exclusion. If someone is injured or their property is damaged in connection with your business, the policy is designed not to respond.

Practical version: a client comes to your Rockville house for a meeting, catches a heaved slate on the front walk in February, and breaks a wrist. Because the visit was business-related, your homeowners carrier can deny the claim — and you are personally on the hook for the medical bills and any judgment.

Maryland's pure contributory negligence rule means an injured visitor who was even slightly at fault may recover nothing at all, which sounds like good news for you. It is not a coverage strategy. It is an argument you have to pay a lawyer to make, without a carrier funding the defense.

3. Professional Liability: The Gap Most Consultants Don't Know They Have

If you are paid for advice, analysis, design or a deliverable, your biggest exposure isn't a fire — it's a client who says your work was wrong and cost them money. That's professional liability, also called errors and omissions, and it exists on neither your homeowners policy nor a basic general liability policy.

This matters disproportionately in Montgomery County because of who lives here. If you subcontract to a prime on a federal contract, sit on an advisory retainer, or do regulated work — accounting, IT security, healthcare consulting, real estate, therapy — the contract itself will very often require you to carry E&O and produce a certificate before you can start. Plenty of home-based consultants first learn this the week a contract is ready to sign. We place professional liability through ERGO Next and Tapco, two of the carriers we represent for small-firm E&O.

4. Your Personal Auto Policy Has a Business-Use Problem

Driving to a client meeting is usually fine. Using the car as part of the business generally isn't. Regular deliveries, hauling equipment and materials to job sites, or carrying products for sale can all fall outside a personal auto policy's intended use — and a claim is exactly when the carrier looks closely at what you were doing.

If your work involves a van, a trailer, a magnetic door sign, or a route you drive most days, tell your agent. The fix is often a straightforward endorsement rather than a full commercial auto policy, but only if the conversation happens before the accident.

5. One Helper Can Trigger Workers Compensation

The moment you pay someone to help — an assistant a few hours a week, a part-time crew member, a neighbor's kid who works the busy season — you may be in Maryland's workers compensation system. Owners routinely assume part-time or informal arrangements don't count. Frequently they do.

Getting this wrong is uniquely expensive: an uninsured on-the-job injury can mean paying the claim directly plus penalties. If you have any paid help at all, verify your obligation now. Our Maryland workers compensation guide walks through who is and isn't covered.

6. Client Data Is a Liability You're Storing for Free

A home-based therapist holds clinical records. A bookkeeper holds bank credentials and Social Security numbers. An IT consultant holds administrative access to someone else's network. That data sits on a laptop on a kitchen table behind a consumer router.

Homeowners insurance does nothing here. A breach means notification costs, credit monitoring, regulatory exposure and, for anyone touching health information, HIPAA consequences. Cyber liability is inexpensive at this size and is increasingly written into client contracts alongside E&O.

Don't Forget the County Side

Insurance isn't the only box to tick. Montgomery County regulates home-based businesses through its zoning code, and most home occupations require registration with the Department of Permitting Services, with limits on things like employees on site, customer traffic and signage. Rules differ by zone and change periodically, so confirm current requirements with DPS directly rather than relying on what a neighbor did in 2019.

It's worth doing for its own sake — and an unregistered operation is one more fact a carrier can point at when a claim gets scrutinized.

So What Do You Actually Buy?

For most home-based businesses in Montgomery County, this lands in one of two places.

An in-home business endorsement. An add-on to your existing homeowners policy that raises the business property limit and adds a modest slice of business liability. For a solo, low-revenue operation with no employees, no inventory and no client visits, this is often enough and costs very little.

A business owners policy (BOP). A packaged commercial policy combining property and general liability, with professional liability, cyber and commercial auto added as needed. Once you have employees, foot traffic, meaningful equipment, or contracts demanding certificates of insurance, this is the honest answer. We write small-business packages through Erie among the carriers we represent.

The distinction that actually decides it isn't revenue. It's whether anyone other than you is affected when something goes wrong — an employee, a client on your property, or a client relying on your work.

The Fifteen-Minute Version

If you are running a business from a home in Rockville, Bethesda, Silver Spring, Gaithersburg or anywhere else in Montgomery County, ask yourself four questions: How much business property is under this roof? Does anyone come here for business? Does anyone pay me for judgment or a deliverable? Do I pay anyone to help?

Any yes means your current policy has a hole in it. As an independent agency in Rockville, we can compare an endorsement against a full business policy across the carriers we represent — instead of one captive company's single shelf — and tell you honestly which one your situation calls for. For most home-based businesses that conversation takes about fifteen minutes and ends with a smaller number than people expect.
