Home Insurance: What's Actually Covered — and What Isn't

Most people find out what their policy doesn't cover right after they file a claim. Read this first.

Homeowners insurance is one of those things most people buy once, stuff in a filing cabinet, and never look at again until something goes wrong. That's a problem — because the time to understand what your policy covers is not when you're standing in three inches of water or watching a tree sit on your roof.

A standard homeowners policy (the industry calls it an HO-3) covers a lot — but it has specific exclusions that surprise people every single year. Here's the complete picture in plain language.

What a Standard HO-3 Policy Covers

Your Dwelling (the house itself)

This is the main coverage — damage to the physical structure of your home. A standard HO-3 policy covers your dwelling against "all perils" except those specifically excluded. That means it covers fire, smoke, lightning, windstorm, hail, explosion, vandalism, theft, falling objects (like a tree), weight of ice and snow, and damage from burst pipes, among others.

Critical detail: your dwelling coverage should equal the replacement cost — what it would cost to rebuild the house from scratch at today's construction prices — not its market value. These can differ significantly. In high-demand markets, land value inflates market prices. In areas with high construction costs, replacement cost can actually exceed market value.

Other Structures

Detached structures on your property — garage, fence, shed, guesthouse — are typically covered for 10% of your dwelling coverage limit. If your house is insured for $400,000, your detached garage is covered up to about $40,000. If you have a valuable separate structure, you may want to increase this limit specifically.

Personal Property

Your stuff — furniture, clothing, electronics, appliances, sports equipment. Standard policies cover personal property for 50–70% of dwelling coverage, so a $400,000 dwelling policy would cover $200,000–$280,000 worth of contents. Important: most policies default to "actual cash value" for personal property, which means depreciated value. A 5-year-old TV that cost $1,200 might be worth $200 at actual cash value. Ask about "replacement cost value" coverage for your personal property — it costs a bit more but pays you what things actually cost to replace, not what they're worth now.

Loss of Use (Additional Living Expenses)

If your home becomes uninhabitable due to a covered loss, your policy pays for temporary housing — hotel, rental, meals out — while your home is being repaired. This coverage is typically capped at 20% of dwelling coverage or for a defined time period. Don't underestimate this: quality repairs take months, and temporary housing is expensive.

Liability Coverage

If someone is injured on your property and sues you, your homeowners policy covers legal defense and damages up to your liability limit. Standard policies include $100,000–$300,000 in liability coverage. For homeowners with significant assets, an umbrella policy on top of this is worth considering — it adds $1 million or more in liability coverage for very little additional cost.

Medical Payments to Others

If a guest is hurt on your property, this covers minor medical bills ($1,000–$5,000 typically) regardless of fault — without needing to prove liability. It's designed to handle small claims and prevent them from escalating.

What Is NOT Covered (The Big Surprises)

⚠️ These exclusions catch homeowners off guard every year. Know them before you need them.

Floods

Standard homeowners insurance does not cover flood damage. Full stop. Flood damage from storms, overflowing rivers, storm surge, or heavy rainfall requires a separate flood insurance policy — either through the National Flood Insurance Program (NFIP) or a private insurer. If you live in a flood zone, your mortgage lender likely requires flood insurance. If you're not in a designated flood zone, it's still worth considering — about 25% of flood claims come from outside high-risk zones.

Earthquakes

Also not covered under a standard policy. If you live in a seismically active area, you need a separate earthquake policy. California and Pacific Northwest residents especially: this gap can be catastrophic to skip.

Maintenance Issues and Wear

Insurance covers sudden, accidental damage — not gradual deterioration. A burst pipe that ruins your floors is covered. A slow plumbing leak you didn't fix for two years that eventually causes mold is not. Roof damage from a windstorm is covered. A roof that simply aged out and started leaking after 25 years is not. Insurance is not a home warranty.

Mold (Usually)

Mold is one of the most contentious coverage areas. Most policies exclude mold damage unless it's a direct result of a covered peril (like a burst pipe). Mold from chronic humidity, poor ventilation, or deferred maintenance is typically not covered.

Sewer Backup

Water damage from a backed-up sewer or drain is not covered by a standard policy. You can add "water backup" coverage as an endorsement for a modest additional premium — usually $50–$100/year. Given that a sewer backup can cause thousands of dollars in damage, this endorsement is almost always worth adding.

High-Value Items Above Policy Limits

Standard policies cap coverage for specific categories — jewelry, watches, art, firearms, electronics, collectibles — at relatively low sub-limits (often $1,500–$2,500 per category). If you have engagement rings, expensive watches, camera equipment, or other high-value items, you'll need a scheduled personal property endorsement (sometimes called a "rider" or "floater") to cover their full value.

Am I Insured for the Right Amount?

The most common home insurance mistake is being insured for market value instead of replacement cost. These are very different numbers:

Request an updated dwelling replacement cost estimate from your insurer, or use an independent replacement cost calculator, before your next renewal. If your coverage limit hasn’t kept pace with construction inflation, close the gap now — not after a claim.

Extended Replacement Cost endorsement: This valuable add-on pays an additional 25–50% above your dwelling limit if reconstruction costs exceed your coverage amount. Given ongoing construction cost volatility, this endorsement is worth the modest additional premium.

Three Upgrades Worth Adding

  1. Replacement cost value for personal property — covers what things cost to replace, not what they're worth now
  2. Water backup endorsement — covers sewer/drain backup damage (usually $50–$100/yr)
  3. Scheduled personal property rider — for jewelry, art, cameras, or other high-value items

Frequently Asked Questions

Does home insurance cover roof damage?

Yes — for sudden, storm-related damage. A tree falls on your roof in a windstorm: covered. Hail punches through your shingles: covered. A roof that has simply aged past its useful life and is leaking: not covered. Some insurers also depreciate roof claims based on the roof’s age, paying you less than full replacement cost if your roof is 15+ years old. Ask about roof claims handling specifically when shopping.

What’s the difference between a named perils and open perils policy?

Named perils policies cover only the causes of damage specifically listed in the policy (fire, theft, wind, etc.). Open perils (also called “all risk”) policies cover everything except what’s specifically excluded. HO-3 policies use open perils for the dwelling and named perils for personal property. HO-5 — an upgrade available from some insurers — uses open perils for both, providing broader personal property coverage.

Does home insurance cover theft of items outside my home?

Often yes — up to your personal property limits and subject to off-premises sub-limits (typically 10% of your personal property limit). A laptop stolen from your car may be covered under your home insurance. Items stolen from a storage unit may be covered at reduced limits. This is why renters and homeowners insurance can replace dedicated travel insurance for many common personal property situations.

Can I lower my home insurance premium without reducing coverage?

Yes — several strategies:

What is an umbrella policy and do I need one?

An umbrella policy provides additional liability coverage above and beyond what your homeowners and auto policies provide — typically $1 million increments at around $150–$300/year. It kicks in after your underlying liability limits are exhausted. Homeowners with significant assets, pools or trampolines (higher accident risk), teenage drivers, or public-facing professions are the best candidates for umbrella coverage.

How does home insurance work if I have a home-based business?

Standard home insurance provides very limited coverage for business activities at home — typically capping business property at $2,500 and providing no liability coverage for business-related injuries. If you have clients visiting your home, expensive business equipment, or significant business income at risk, you need a home business endorsement or a separate business owner’s policy (BOP).

💡 Bottom line: A standard HO-3 policy is solid coverage — but the exclusions for floods, earthquakes, and maintenance issues are real gaps. Know your policy, add the right endorsements, and make sure your coverage limits reflect what it would actually cost to rebuild today.
