What Your Homeowners Insurance Does Not Cover

The Gaps Most Homeowners Do Not Know About

Most homeowners assume their insurance covers just about everything that could go wrong with their house. It does not. A standard homeowners policy (the most common type is called an HO-3) covers a long list of events -- fire, theft, windstorms, hail, lightning, falling objects, and more. But the exclusions are where people get caught off guard, usually at the worst possible time: when they file a claim and find out it is not covered.

Understanding what your policy does not cover is just as important as knowing what it does. Here are the most common gaps.

Flooding

This is the big one. Standard homeowners insurance does not cover flood damage. It does not matter whether the flood comes from a river, a storm surge, heavy rain overwhelming a drainage system, or a nearby creek that overflows -- none of it is covered under a standard policy. This catches a lot of people off guard because they assume "water damage" is covered. Your policy does cover sudden water damage from things like a burst pipe or an overflowing washing machine. But rising water from outside the home is a flood, and that requires a separate flood insurance policy.

Flood insurance is available through the National Flood Insurance Program (NFIP) and some private insurers. Even if you do not live in a designated high-risk flood zone, the coverage may be worth considering. According to FEMA, more than 40% of flood claims come from properties outside of high-risk areas. Policies typically have a 30-day waiting period before coverage takes effect, so you cannot buy one when a storm is already in the forecast.

Sewer and Drain Backup

If your sewer line backs up and sends water or waste into your basement, a standard homeowners policy typically does not cover the damage. This is a separate endorsement (an add-on to your existing policy) that usually costs $40-$75 per year. Given that sewer backups are one of the most common causes of basement damage in the United States, this is one of the most practical add-ons available. Ask your insurance agent if you do not already have it.

Earthquakes and Earth Movement

Standard policies exclude damage from earthquakes, landslides, mudslides, sinkholes, and other earth movement. If you live in a seismically active area, separate earthquake insurance is available. In California, the California Earthquake Authority (CEA) is the most common source. Earthquake policies typically have higher deductibles (often 10-20% of the dwelling coverage) than standard homeowners policies.

Mold

Mold coverage is limited or excluded in most standard policies. If mold results from a covered event -- like water damage from a burst pipe that you addressed promptly -- some policies will cover it, often with a cap (commonly $5,000 to $10,000). But mold caused by ongoing humidity, poor ventilation, slow leaks, or flooding is generally excluded. Given that mold remediation can easily cost $10,000 to $30,000 or more, this is a meaningful gap.

Wear and Tear, Maintenance, and Neglect

Insurance covers sudden and accidental damage. It does not cover damage that results from failing to maintain your home. If your roof leaks because it is 25 years old and worn out, that is not covered. If a tree falls on your roof during a storm, that is covered. The distinction is important: the cause of the damage determines coverage, not just the damage itself. Similarly, termite damage, pest infestations, and rot from long-term moisture issues are considered maintenance problems, not insurable events.

Home Business Equipment and Liability

If you run any kind of business from home -- whether it is a side job, a craft business, or a home office for your full-time work -- your standard homeowners policy may not cover business equipment, inventory, or liability related to business activities. A client who trips on your front step while visiting your home office may not be covered under your homeowners liability. Depending on the nature of your business, you may need a home business endorsement or a separate business policy.

How to Check Your Own Policy

Pull out your declarations page (the summary of your policy that lists your coverages and limits) and read the exclusions section. If you do not have a copy handy, call your insurance agent and ask them to walk you through what is and is not covered. Ask specifically about flood, sewer backup, mold, and any other risks relevant to your property. A 15-minute phone call could save you from a devastating surprise down the road.
