How to insure a home-based business

A home policy is written for a household, and it says so in its definitions. Property used in a business is covered only up to a modest sublimit on the premises and a smaller one away from it; liability arising from business activities is excluded outright, with narrow exceptions; and income lost when the house is uninhabitable is covered for living expenses, not for the business that stopped. A consultant with a laptop may sit comfortably inside those limits. A woodworker with a garage shop, a home baker with a commercial oven, a bookkeeper holding client records or a photographer with a bag of lenses does not, and the gap is discovered at the claim.

The fix is not one product. Depending on what the business owns, who comes to the door and what could go wrong, it ranges from a small endorsement on the home policy to a stand-alone business owners policy. This guide is the sequence for working out which, and it applies to the home-based businesses common across Arizona, Nevada, Utah and Idaho, from Etsy sellers to licensed contractors who run the office from a spare room.

What to gather

The right structure depends on facts you already know but may not have written down.

• The current homeowner or renters declarations page, and the policy form, so you can find the business property sublimit and the business liability exclusion.
• A list of business property kept at home with replacement values: computers, tools, machinery, inventory, samples, cameras, specialised furniture, and anything you take to clients or markets.
• Annual revenue and a rough count of how many clients, customers, deliveries or employees come to the house in a month.
• Whether you hold client property or data: documents, goods left for repair, personal or payment information.
• Any contracts, platform terms, licences or professional bodies that require insurance of a stated kind, and the certificates they ask for.
• Whether you use a vehicle for the business, and whether anyone else drives it for that purpose.

Step one: read what the home policy already does

Find the business property sublimit on the declarations page or in the form's special limits. It is a fixed amount for business property on the residence premises and a lower amount away from it, and it applies per occurrence, not per item. Compare it with the replacement value of the list you made. For many desk-based businesses the sublimit is enough or nearly so; for anything with equipment or stock it is not close.

Then find the liability section's business exclusion. Most forms exclude bodily injury and property damage arising out of a business conducted from the residence, with an exception for certain incidental activities and for some home day care, which varies by carrier. That means a client who trips on the step while collecting an order, or a customer's goods damaged in your care, is not the home policy's problem. Loss of business income, professional errors, employees' injuries, cyber events and vehicles used for business are outside the home policy entirely. Write down which of these apply to you; that list is the specification for what follows.

Step two: choose the structure

There are three broad options, and the size of the exposure list picks between them. The first is a business endorsement on the home policy, sometimes called a home business or incidental business endorsement. It raises the business property sublimit, adds a modest amount of business liability for visitors, and sometimes a little income coverage. It suits a low-traffic, low-inventory business with no employees: a consultant, a tutor, a designer, a part-time seller with limited stock. It is inexpensive and stays on one policy, and it has ceilings that cannot be raised much.

The second is an in-home business policy, a stand-alone policy written for exactly this situation. It carries higher property limits on and off premises, more liability, business income and extra expense, and often money and securities, accounts receivable and valuable papers. It suits a business with equipment or stock worth more than the endorsement will carry, regular customer visits, or a contract that requires a certificate of insurance with named limits.

The third is a business owners policy, which packages commercial property and general liability for a small business and is written on commercial forms. It becomes the right answer once the business has employees, meaningful inventory, a delivery vehicle, or clients who require higher liability limits and additional insured status. A home-based contractor, a caterer, or a maker who sells at markets around the region usually lands here. Whichever option fits, tell the home carrier about the business; a carrier that learns of an undisclosed business at a claim can decline the claim on the home side too.

Step three: close the gaps none of the three covers

Each of the following is a separate policy or endorsement, and each is triggered by a fact on your list.

• Professional liability, also called errors and omissions, if clients rely on your advice, designs, plans, bookkeeping or consulting. Property and general liability policies do not respond to a client's financial loss from your mistake.
• Workers compensation, if you have employees, including part-time help. Each of the four states sets the threshold at which it becomes compulsory, and the rules on family members and contractors differ; the mechanism is in the state's law, and the analysis confirms where you fall.
• Commercial auto, or at minimum a business-use endorsement on the personal auto policy, if a vehicle carries stock, tools or clients. A personal auto policy can exclude business use, particularly deliveries.
• Cyber liability, if you hold customer payment or personal information or run the business through online platforms. A small policy covers notification, restoration and third-party claims.
• Inland marine or a tools and equipment floater, for property that travels: a photographer's kit, a contractor's tools, market stock. It covers the property wherever it is, which no home policy does above the off-premises sublimit.
• Product liability, folded into general liability on a business owners policy, if you make or sell physical goods, especially food, cosmetics or anything for children.

Step four: check the home itself

A business changes the house as a risk. A commercial oven, a kiln, a spray booth or a stock of solvent in the garage affects the fire picture and can be a reason for the home carrier to add conditions or decline at renewal if it was not told. Zoning and HOA rules in many Arizona and Nevada subdivisions restrict customer traffic and signage, and a business operating in breach of them can complicate a liability claim. If a structure on the property is used mainly for the business, such as a converted shed or a detached studio, the home policy's other-structures coverage may exclude it, and it needs to be scheduled or moved to the business policy.

For a renter, the same logic applies with the landlord's consent as an extra step. The lease often prohibits business use or requires notice, and the landlord may ask for a certificate naming them as additional insured on the business liability policy.

Common mistakes

These are the reasons home-business claims are denied or underpaid.

• Assuming the home policy covers business property at its full contents limit. The sublimit governs.
• Not telling the home carrier about the business, which puts the household's own coverage at risk as well as the business's.
• Buying an endorsement when the property list already exceeds what it can carry.
• Treating a client's certificate request as paperwork rather than as a specification of the limits and the additional insured status the contract requires.
• Running deliveries in a personal car on a personal policy.
• Forgetting that a claim on the home policy for business property, even within the sublimit, is still a claim on the home policy and rates it.
• Keeping the only copy of client records and the inventory on a computer in the house.

A worked example

Suppose a jeweller in Tucson makes pieces in a converted spare room and sells at weekend markets and online. Her home policy has a $2,500 business property sublimit on premises and $500 away, and excludes business liability. Her tools and stock at home come to $18,000; she carries $4,000 of stock to markets; she has no employees, and around twenty customers a year collect in person. The endorsement cannot carry the property, so she is quoted an in-home business policy at say $900 a year with $25,000 of business property on premises, $5,000 off premises, $500,000 of liability including products, and $10,000 of business income. She adds a $300 a year cyber policy because she stores customer addresses and processes cards through a platform, and tells the home carrier about the workshop, which adds nothing to the home premium. A year later a market tent collapses and destroys $3,200 of stock; the off-premises limit pays it less a $250 deductible. Under the home policy alone the same loss would have paid $500 at most, and a customer's cut hand at her front door would have paid nothing. Figures are illustrative.

How to use this

Bring us the home declarations page and the list of business property, visitors and contracts, and we say which of the three structures fits, price it against the carriers we represent in Arizona, Nevada, Utah and Idaho, and list the separate policies your particular business needs from the gap section. If the business is small enough that the home policy's sublimits genuinely cover it, we say so and recommend only that the carrier be told.
