Home insurance across all states: how coverage works and what shapes your premium
Last reviewed September 3, 20265 min readBy the Goodsurance editorial team Reviewed by the Goodsurance editorial team
Homeowners insurance pays to repair or rebuild your home after a covered loss, replaces personal belongings, and protects you financially if someone is injured on your property. No federal law requires it, but virtually every mortgage lender does, which makes it a practical necessity for most owners regardless of state.
What a standard homeowners policy covers
A standard policy (commonly referred to in the industry as an HO-3 form) bundles four core protections:
Dwelling coverage pays to repair or rebuild the physical structure of your home and attached features such as a garage, up to your chosen coverage limit.
Personal property coverage reimburses you for belongings damaged or stolen, whether inside the home or away from it. Some policies pay actual cash value, which accounts for depreciation; others pay replacement cost, which typically costs more in premium but pays out more after a loss.
Liability coverage steps in if you or a household member causes bodily injury or property damage to someone else and that person pursues a claim or lawsuit.
Additional living expenses (ALE) cover temporary housing and extra day-to-day costs while your home is being repaired after a covered event.
HO-3 policies cover the dwelling itself against all risks except those specifically excluded, while personal property coverage typically applies only to a named list of perils. Reading both the coverage section and the exclusions section of any policy you are considering is the only way to understand what you are actually buying.
- Pays what your item was worth at the time of loss, after depreciation
- Lower premium cost
- Payout may not cover the full cost to replace the item today
- Pays what it costs to buy a similar new item today
- Higher premium cost
- Pays out more after a loss
How state law shapes your policy
Each state's department of insurance sets the rules under which carriers write policies, file and justify rate changes, and handle consumer complaints. This means the same underlying product can differ meaningfully from one state to the next in terms of required disclosures, claims-handling timelines, and which exclusions a carrier is permitted to apply.
States facing elevated catastrophe risk show the most visible regulatory differences. Several coastal and wildfire-prone states maintain insurers of last resort, often called FAIR Plans, for homeowners who cannot obtain coverage through the standard private market due to hurricane, wildfire, or other catastrophe exposure. These plans serve as a safety net but typically offer narrower coverage than a competitive market policy.
Your state's department of insurance is the authoritative place to look up which carriers are licensed to operate in your state, check complaint ratios for any company you are evaluating, and verify that the policy form being offered has been filed and approved. The National Association of Insurance Commissioners (NAIC) maintains a directory of all state insurance regulatory offices at naic.org.
What drives your premium
Because no federal pricing standard governs homeowners insurance, premiums vary widely across and within states. Underwriters weigh several factors when setting a rate:
- Location and catastrophe exposure. Proximity to a coastline, a wildfire-prone area, or a flood zone raises the statistical probability of a large loss, which pushes the premium up.
- Construction age, materials, and condition. An aging roof or outdated electrical system signals higher risk. Newer construction with fire-resistant materials and updated systems typically rates more favorably.
- Coverage amount and deductible. Higher dwelling limits mean a larger potential payout; a higher deductible shifts more of the first-loss cost to you and reduces the premium accordingly.
- Claims history. Your personal claims history and the claims history attached to the property itself both factor into underwriting decisions.
- Credit-based insurance score. Most states allow insurers to use a version of your credit history as a rating factor. A handful of states, including California, Maryland, and Massachusetts, restrict or prohibit this practice.
The NAIC's 2024 homeowners property insurance market dynamics report documents meaningful regional variation in average premiums, with the Southeast running considerably higher than the Northeast. That gap reflects regional differences in storm frequency, construction costs, and claims severity rather than any single carrier's pricing decision.
The Southeast pays considerably more than the Northeast, driven by storm risk and local claims costs
Gaps every homeowner should know about
Standard homeowners policies exclude two of the most financially serious events a homeowner can face: floods and earthquakes.
Flood coverage is sold separately from a standard homeowners policy. The federal National Flood Insurance Program (NFIP), administered by FEMA, offers flood policies to homeowners in participating communities. Private flood insurance options also exist in many states and may offer higher limits or broader coverage terms than the NFIP. FEMA's flood map service center (msc.fema.gov) lets you look up your property's current flood zone designation, which directly affects both your risk and your eligibility for subsidized NFIP rates.
Earthquake coverage is typically available as a separate policy or an endorsement. In California, the California Earthquake Authority functions as the primary source of residential earthquake insurance, offered through participating insurers.
Other exclusions that catch homeowners off guard include sewer or water backup, ordinance or law coverage (which pays the added cost of bringing a rebuilt structure up to current building codes), and damage from gradual deterioration. Endorsements exist for most of these gaps, and comparing what each carrier charges for them can be as important as comparing the base premium.
What your standard policy covers and what it leaves out
Covers
- Physical damage to your home from most sudden events
- Belongings damaged or stolen inside or outside your home
- Liability if someone is injured on your property
- Temporary housing costs while your home is being repaired
Does not cover
- Flood damage (requires a separate policy)
- Earthquake damage (requires a separate policy or endorsement)
- Sewer or water backup
- Gradual deterioration and wear
Endorsements and separate policies can fill these gaps. Compare what each carrier charges for them.
How to shop across all states
Shopping for homeowners insurance is an exercise in comparing like for like. Requesting quotes with identical dwelling coverage limits, the same deductible, and the same set of endorsements is the only way to make premiums directly comparable. A policy that appears cheaper on a summary sheet may carry a separate wind or hail deductible that applies independently from the main deductible.
Your state's department of insurance publishes complaint index data showing whether a carrier generates more or fewer complaints than the market average for its size. A persistently high complaint index is worth taking seriously, particularly for claims handling. Licensing status is also verifiable through the same department, which confirms that a company you are considering is authorized to write coverage in your state.
Coverage needs also shift over time. A renovation that adds square footage, a finished basement, or a new detached structure can all affect whether your current dwelling limit still accurately reflects the cost to rebuild. Reviewing your coverage annually, or after any significant change to the property, keeps your policy aligned with what it is meant to protect.

What is collision coverage on a car insurance policy?
Collision coverage is the part of a car insurance policy that pays for damage to your own car after a crash.
It applies when your car hits another vehicle or an object, and when your car flips over. You choose a deductible, which is the share of the repair bill you pay before the insurer pays the rest. Collision is optional in most cases, but a lender or a leasing company often requires it while you still owe money on the car.
Do I need collision coverage if my car is paid off?
It depends.
Once the loan is paid off, no lender can require collision coverage, so the choice is yours. Ask yourself one question: if your car were wrecked tomorrow, could you replace it out of pocket without hurting your household? If the answer is no, collision still does real work. If the car is old and worth little, the claim payment may be small, since collision pays based on what the car is worth, not what a new one costs.
What does comprehensive car insurance cover?
Comprehensive covers damage to your car that does not come from a crash with another vehicle or an object.
Think of it as protection from events you cannot steer around. That includes theft, fire, hail, falling tree limbs, flooding, vandalism, and hitting an animal on the road. Broken glass usually falls here too. You pick a deductible, which is the part of the bill you pay before the insurer pays the rest. Comprehensive is optional unless a lender requires it.
Does comprehensive insurance cover a cracked windshield?
Yes.
Glass damage is usually handled under comprehensive, not collision, because a rock or road debris is not a crash. If a stone chips your windshield on the highway, that is a comprehensive claim. Your deductible still applies, which is the share of the bill you pay first. Some states require insurers to offer glass coverage with a lower deductible or none at all, and those rules vary by state. Fixing a small chip early usually costs less than a full replacement.
What happens if a deer runs into my car?
Hitting an animal is normally a comprehensive claim, not a collision claim, even though it feels like a crash.
Comprehensive covers the damage the animal caused to your car, minus your deductible. There is an odd twist: if you swerve to miss the deer and hit a tree or a ditch instead, that becomes a collision claim, because you struck an object. Report the incident to your insurer either way, and take photos of the damage before any repairs begin.
What is the difference between comprehensive and collision insurance?
Both pay for damage to your own car, but they split the world in two.
Collision handles crashes: hitting another vehicle, hitting an object like a pole or a guardrail, or rolling your car over. Comprehensive handles almost everything else: theft, fire, hail, flooding, vandalism, falling branches, and hitting an animal. Each one carries its own deductible, which is the part of the bill you pay before the insurer pays. You can buy them together or, in many cases, separately.
Is a stolen car covered by collision insurance?
No.
Theft falls under comprehensive coverage, not collision. Collision only pays when your car strikes another vehicle or an object, or when it rolls over. If your car is stolen and never found, comprehensive pays what the car was worth at the time it was taken, minus your deductible. If it is recovered with damage, comprehensive covers the repairs. File a police report first, since insurers ask for the report number when they open a theft claim.
Can I buy comprehensive without collision?
It depends on the insurer and on whether you owe money on the car.
Many insurers will sell comprehensive alone, since it covers theft, fire, and weather damage while the car sits parked. Buying collision alone is far less common. If a lender or a leasing company holds the title, it usually requires both, and that rule sits in your loan or lease contract, not in state law. Ask your insurer which pairings it allows before you drop a coverage.
What does an HO-6 condo insurance policy cover?
An HO-6 is the policy written for a condo owner.
It covers the parts of the home you own and the association does not: interior walls, flooring, cabinets, fixtures, and built in features, depending on how your association documents split things. It also covers your belongings, your liability if someone is hurt in your unit, and a place to stay if a covered loss makes your unit unlivable. Many policies add loss assessment coverage for your share of a building claim.
Do I need condo insurance if the building already has a master policy?
Yes.
In almost every case you still need your own policy. The master policy the association buys covers the building shell and shared areas like hallways, the roof, and the lobby. It does not cover what is inside your unit, your belongings, or your personal liability. Read your association bylaws to see where the master policy stops, since the dividing line differs from building to building. An HO-6 policy fills that space. Lenders usually require one before they will finance a condo.
What is loss assessment coverage on a condo policy?
When a covered loss hits the shared parts of a condo building and the master policy does not pay all of it, the association can bill each owner a share.
That bill is called an assessment. Loss assessment coverage is the piece of your HO-6 policy that helps pay your share. It applies to assessments tied to a covered loss, not to routine repairs or normal upkeep. Coverage amounts and rules vary by policy, so check your declarations page.
Does collision coverage pay if I hit a tree?
Yes.
Collision coverage pays to fix or replace your car when it crashes into an object or another vehicle. A tree counts as an object. It also applies if you hit a fence, a pole, or a guardrail, or if your car rolls over. You still pay your deductible first, which is the part of the repair bill you cover. Collision pays for your car damage even when the crash is your fault. It does not pay for the other driver's car.
