What homeowners insurance actually covers and what it doesn't

Homeowners insurance has two main parts: the building itself and your belongings inside it. The building coverage pays to rebuild or repair the structure if it burns, gets hit by a storm, or suffers other damage listed in your policy. It does not cover damage from floods or earthquakes — those require separate policies you buy on top of standard homeowners insurance.

The second part, called personal property coverage, pays to replace your furniture, clothes, electronics, and other items if they are stolen or damaged by a covered event. Most policies cover about 50 to 70 percent of your home's rebuilding cost for personal property, though you can increase that if you own expensive items. Homeowners insurance also includes liability coverage, which pays if someone is injured on your property and sues you, or if you accidentally damage someone else's property.

What homeowners insurance does not cover: water damage from backed-up sewers or foundation leaks, damage from poor maintenance, loss from war or civil unrest, and damage to detached structures like sheds or garages (unless you add that coverage). Flood damage is the most common exclusion — even a few inches of water from heavy rain is not covered by a standard policy.

Key Takeaways

  • Standard homeowners insurance covers the building structure and your belongings, but excludes floods and earthquakes, which require separate policies.
  • The amount of coverage you need depends on what it would cost to rebuild your home from the ground up, not what you paid for it.
  • Your deductible — the amount you pay out of pocket before insurance kicks in — directly affects your monthly premium; higher deductibles lower your cost.
  • Discounts for bundling policies, installing security systems, or maintaining a good claims history can reduce your premium by 10 to 25 percent depending on the insurer.
  • You should review your policy once a year and after major home improvements, because coverage amounts may no longer match what your home is actually worth.

How to calculate the coverage amount you actually need

The coverage amount should equal the cost to rebuild your home from scratch, not the market value or what you paid for it. A home worth $400,000 might cost $600,000 to rebuild if construction costs in your area are high, or $350,000 if you live somewhere with lower labor and material costs. The only way to know is to get a professional estimate or use your insurer's online calculator, which asks about square footage, construction type, and local building costs.

Start by contacting two or three insurers and asking them to run a replacement cost estimate for your address. They do this free and it takes about 10 minutes. Write down the number each one gives you — it will vary slightly because insurers use different cost databases. Use the highest number as your coverage amount, because underinsuring means you pay more out of pocket if you have a claim.

If you have made major improvements — a new roof, foundation work, an addition — tell the insurer before they estimate, because those changes affect the rebuilding cost. If you have not updated your coverage in three or more years, ask for a new estimate; construction costs shift and your old number may be too low.

Understanding deductibles and how they affect your premium

Your deductible is the amount you pay toward a claim before the insurance company pays the rest. Common deductibles are $500, $1,000, $2,500, and $5,000. Choosing a higher deductible lowers your monthly premium — sometimes by 15 to 30 percent — but it means you pay more if you file a claim. A $5,000 deductible might save you $30 a month, but if a storm damages your roof for $8,000, you pay $5,000 and insurance pays $3,000.

The right deductible depends on what you can afford to pay out of pocket if something happens. If you have $10,000 in savings and feel find, a $2,500 or $5,000 deductible makes sense because the monthly savings add up. If you have less savings or would struggle to pay a large amount suddenly, stick with $500 or $1,000 even if the premium is higher.

Some insurers also offer a percentage-based deductible for wind or hail damage — for example, 2 percent of your home's coverage amount. On a $400,000 home, that would be an $8,000 deductible just for that type of damage. Ask your insurer whether percentage deductibles explore in your area and whether you can choose a dollar amount instead.

Comparing quotes from different insurers

Do not call one insurer and take their first quote. Get quotes from at least three companies — State Farm, Allstate, GEICO, Progressive, Amica Mutual, and local or regional insurers all operate in most states. Each one prices risk differently, so the same home can cost $800 a year with one company and $1,200 with another.

When you request quotes, give every insurer the exact same information: your home's age, square footage, construction type (wood frame, brick, etc.), roof age, number of bathrooms and bedrooms, and whether you have a security system or smoke detectors. If you change details between quotes, the prices will not be comparable. Ask each insurer for the same coverage amount and deductible so you are comparing apples to apples.

Write down the premium, deductible, coverage limits, and any discounts each insurer mentions. Then look at the total cost over three years — a company with a lower annual premium but fewer discounts might cost more overall than one with a higher premium but bigger savings for bundling or claims-free history. Check each insurer's customer service ratings on the National Association of Insurance Commissioners website (naic.org) before you decide; a cheap policy is not worth it if the company is slow to pay claims.

Discounts that actually reduce your cost

Most insurers offer a discount for bundling homeowners and auto insurance — usually 10 to 25 percent off each policy. This is often the single largest discount available. If you currently have auto insurance elsewhere, getting a quote for both policies bundled with one company usually saves money even if that company's base rate is slightly higher.

Other common discounts include: installing a security system or deadbolt locks (5 to 10 percent), being claims-free for three to five years (5 to 15 percent), paying your premium in full rather than monthly (1 to 5 percent), being a homeowner for a certain number of years (5 to 10 percent), and retiring or working from home (5 percent). Some insurers also discount if your home was built recently or has a newer roof or electrical system.

Ask each insurer to list every discount you might be may be able to access for, not just the ones they mention first. Some companies do not advertise certain discounts prominently. If you are considering a security system mainly for the insurance discount, calculate whether the discount will pay back the cost of installation within a few years — sometimes it does not.

When to add extra coverage beyond the standard policy

Standard homeowners insurance has limits on certain items. Jewelry, cash, and collectibles are usually covered for only $1,500 to $2,500 total, even if you own much more. If you have an engagement ring worth $5,000, a coin collection, or expensive art, you need to add a rider or endorsement — a separate coverage that protects those specific items for their full value.

You also need separate flood insurance if you live in a flood zone or even just in an area where flooding is possible. The National Flood Insurance Program (NFIP) sells flood policies through private insurers, and some private companies now offer flood coverage too. Flood insurance has a 30-day waiting period, so if you wait until a storm is forecast, you cannot buy it in time. If your mortgage lender requires it, you must have it before closing.

Earthquake insurance is optional in most states but essential if you live in a seismic zone like California, Washington, or parts of the Midwest. It is sold as a separate policy and covers damage from earthquakes that standard homeowners insurance excludes. Umbrella liability coverage — typically $1 million — is worth considering if you have significant assets or if someone could be seriously injured on your property; it costs $150 to $300 a year and covers claims that exceed your homeowners liability limit.

How to review and update your policy each year

Set a reminder to review your homeowners insurance once a year, ideally around the time your policy renews. Check whether your coverage amount still matches what it would cost to rebuild your home — if you have not updated it in three years, get a new estimate. Check whether your deductible still makes sense given your current savings and financial situation. If you have paid off your mortgage, you may be able to lower your coverage slightly, though most people keep it the same.

After any major home improvement — a new roof, foundation repair, addition, or expensive renovation — tell your insurer when ready. These changes increase your home's rebuilding cost and your coverage should increase too. If you do not report them, you may be underinsured and pay more out of pocket in a claim. Some improvements also may have access to you for new discounts, like a discount for a new roof.

If your premium increases significantly at renewal, get new quotes from other insurers before you accept it. Insurers sometimes raise rates for reasons unrelated to your home or claims history — they may have had losses in your area or changed their pricing model. Shopping around every few years, even if you are happy with your current insurer, often saves money because new customers sometimes get better rates than long-term ones.

Frequently Asked Questions

What happens if I am underinsured and have a major claim?

If your coverage amount is less than the actual rebuilding cost, the insurance company will pay up to your coverage limit, and you pay the rest out of pocket. For example, if your home costs $500,000 to rebuild but you only have $350,000 in coverage, insurance pays $350,000 and you owe $150,000. This is why getting an accurate estimate of rebuilding cost is critical.

Do I need homeowners insurance if I own my home outright?

No law requires it if you do not have a mortgage, but it is strongly recommended. Without it, you pay for all repairs and rebuilding yourself — a house fire or major storm could cost hundreds of thousands of dollars. Most people cannot absorb that cost, so homeowners insurance is essential even if a lender does not require it.

Can I lower my premium by increasing my deductible to $10,000?

Some insurers offer deductibles that high, and it will lower your premium, but only choose this if you have at least $10,000 in savings you can access quickly. If a pipe bursts and causes $12,000 in damage, you would pay $10,000 and insurance pays $2,000 — you need to be able to afford that when ready.

What should I do if my insurer denies a claim?

Read the denial letter carefully to understand the reason — it may be that the damage is not covered under your policy, or that you did not follow the claims process correctly. You can file a complaint with your state's Department of Insurance if you believe the denial was unfair. Some states also have an independent review process where a third party reviews the claim.

How often should I shop around for a new insurer?

Every two to three years is reasonable, or whenever your premium increases significantly at renewal. Getting quotes takes about an hour total and can save you hundreds of dollars a year. Even if you stay with your current insurer, the quotes show you what the market rate is and give you leverage to negotiate a lower rate.
