What do I need to know about insuring a garage in Ottawa — is my homeowner's policy enough?

Garage insurance is one of those topics that most Ottawa homeowners do not think about until something goes wrong, and by then it is too late to discover that their coverage has gaps. The good news is that your existing homeowner's insurance policy does cover your garage in most situations — but the details matter, and there are several scenarios common to Ottawa where standard coverage may fall short.

A standard homeowner's insurance policy in Ontario covers your attached garage as part of the dwelling and your detached garage as an outbuilding or other structure, typically at 10 percent of your dwelling coverage limit. So if your home is insured for $500,000, your detached garage is covered for up to $50,000 under most policies. For many Ottawa homeowners with a basic single-car detached garage, this is adequate. But if you have built or are planning to build a larger detached garage — a two-car or three-car structure, a garage with a finished loft, or a garage with workshop space and significant equipment — $50,000 may not come close to the replacement cost. A quality two-car detached garage in Ottawa costs $55,000 to $85,000 to build, and a garage with a finished upper floor can exceed $120,000. If your outbuilding coverage limit is lower than the replacement cost, you are underinsured and would have to cover the difference out of pocket after a total loss.

The fix is straightforward: contact your insurance provider and increase your outbuilding coverage to match the actual replacement cost of your garage. This typically costs an additional $50 to $200 per year in premium depending on the value increase, which is trivial compared to the tens of thousands of dollars in exposure you are eliminating. Provide your insurer with the construction cost or an appraisal value so they can set the limit appropriately.

Contents coverage is the second area where homeowners get caught. Your homeowner's policy covers personal property stored in the garage, but there are often sublimits on specific categories. Tools and equipment may be capped at $5,000 to $10,000 under a standard policy, which is quickly exceeded if you have a well-equipped workshop with a table saw, planer, drill press, compressor, and hand tools. Motorized vehicles (ATVs, snowmobiles, motorcycles, riding mowers) are typically excluded or severely limited under homeowner's policies — they need separate policies or specific endorsements. If you store a boat, trailer, or recreational vehicle in your garage, verify that your policy covers them at their current value while in storage.

For homeowners who operate any kind of business from their garage — even a small side business doing woodworking, automotive repair, or contracting — standard homeowner's insurance almost certainly excludes coverage for business use. If a client visits your garage workshop and is injured, or if your business equipment is damaged in a fire, your homeowner's policy may deny the claim entirely because the garage is being used for commercial purposes. You need either a home-based business endorsement added to your homeowner's policy ($100 to $400 per year) or a separate commercial general liability policy ($500 to $1,500 per year for a small home-based operation).

Liability coverage extends from your homeowner's policy to your garage, meaning if someone is injured in or around your garage — a neighbour helping with a project, a delivery person tripping on your driveway, a child injured by equipment — your liability coverage applies. Most Ontario homeowner's policies include $1 million to $2 million in liability coverage, which is generally adequate. However, if you regularly have people in your garage for any purpose, review your liability limit and consider an umbrella policy ($200 to $400 per year for $1 million additional coverage) for extra protection.

Two Ottawa-specific insurance considerations worth noting. First, if your garage is in a flood-prone area (parts of Constance Bay, Cumberland, Britannia, or near the Rideau River), standard homeowner's insurance does not cover overland flood damage. You need a separate overland water endorsement if available from your insurer, or specific flood insurance. Second, if you are building a new garage, inform your insurer before construction begins. Your policy needs to cover the structure during the construction phase, and the builder should carry their own commercial general liability and WSIB coverage to protect you from liability for construction-related injuries or damage.

When you build, renovate, or significantly upgrade a garage, call your insurance provider and update your policy. The cost of proper coverage is minimal compared to the financial risk of being underinsured. Ottawa Garages can help you find qualified contractors who carry proper insurance and WSIB coverage for your project.
