TL;DR
A standard homeowners insurance policy (HO-3) bundles six types of coverage: dwelling, other structures, personal property, loss of use, personal liability, and medical payments. Together, these protect your home's structure, your belongings, your finances if someone is injured on your property, and your living expenses if disaster forces you out. However, the most financially devastating events that homeowners face are often the ones that standard policies exclude entirely: floods, earthquakes, sewer backups, and mold from gradual leaks. Roughly 40% of flood insurance claims come from properties outside designated high-risk zones, and just one inch of floodwater can cause $25,000 in damage. Before you close on a home, review the coverage gap checklist in this guide, secure the right endorsements, and make sure the policy you are required to carry actually protects you against the risks your specific property faces.
Why Homeowners Insurance Matters for Every Homebuyer
If you are buying a home with a mortgage, your lender will require you to carry homeowners insurance before you can close. This is non-negotiable. The policy protects the lender's collateral, but more importantly, it protects you from financial devastation if something goes wrong with the single largest investment most people ever make.
The standard homeowners insurance policy, known as an HO-3, is the most common form written in the United States. According to the National Association of Insurance Commissioners (NAIC), HO-3 policies account for approximately 79% of all homeowners policies nationwide. This policy type provides open-peril coverage for your dwelling (meaning everything is covered unless specifically excluded) and named-peril coverage for personal property.
Premiums have risen sharply in recent years. A May 2025 NAIC study found that the average HO-3 premium increased 11.2% between 2021 and 2022 alone. According to a U.S. Department of the Treasury report released in January 2025, homeowners insurance is becoming more costly and harder to procure for millions of Americans as climate-related events drive losses higher. Understanding exactly what your policy covers, and what it does not, has never been more important.

Find a Top-Performing AgentThe Six Standard Homeowners Insurance Coverage Types Explained
Every standard HO-3 homeowners insurance policy is divided into six coverage components, labeled Coverage A through Coverage F. Each one protects a different aspect of your financial exposure as a homeowner. The Insurance Information Institute (III) identifies these as the foundational elements of any homeowners policy. Here is what each covers, what it does not cover, and how to determine if your limits are adequate.
| Coverage | What It Covers | What It Does NOT Cover |
|---|---|---|
| A: Dwelling | Your home's structure, attached garage, built-in appliances, decks, patios, and permanently installed fixtures. Pays to repair or rebuild after covered perils. | Flood damage, earthquake damage, normal wear and tear, neglected maintenance, pest infestations, and mold from non-covered events. |
| B: Other Structures | Detached structures on your property: fences, sheds, detached garages, pool houses, and playground equipment. Typically set at 10% of dwelling coverage. | Structures used for business purposes, damage from excluded perils (floods, earthquakes), and structures on property you do not own. |
| C: Personal Property | Furniture, clothing, electronics, appliances, and personal belongings, even when stored off-premises (worldwide). Named-peril coverage for 16 specific hazards. | High-value items above sub-limits (jewelry, art, collectibles typically capped at $1,500-$2,500 for theft). Damage from floods, earthquakes, or intentional acts. |
| D: Loss of Use | Additional living expenses (ALE) if your home becomes uninhabitable due to a covered peril: hotel costs, restaurant meals, and other temporary expenses above normal costs. | Expenses from non-covered events. If you voluntarily leave during renovations or if displacement results from flooding or earthquake, ALE does not apply. |
| E: Personal Liability | Legal defense costs and court-awarded damages if you are found legally responsible for bodily injury or property damage to others. Covers incidents on and off your property. Limits typically start at $100,000. | Intentional acts, business-related liability, injuries to household members, motor vehicle incidents, and professional malpractice. |
| F: Medical Payments | Pays minor medical expenses for guests injured on your property regardless of fault (no-fault coverage). Typically $1,000 to $5,000 per person. | Injuries to you or your household members, injuries from intentional acts, and injuries that exceed the medical payments limit (these become liability claims). |
How to Determine the Right Homeowners Insurance Coverage Amounts
The most important number in your policy is your dwelling coverage limit (Coverage A). This should reflect the full cost to rebuild your home at current construction prices, not the purchase price or market value of the property. Your home's market value includes the land underneath it, which will still be there after a disaster. Rebuilding costs depend on local labor rates, material prices, and the complexity of your home's design.
The 80% Rule
Most insurers require you to insure your home for at least 80% of its replacement cost. If your coverage falls below this threshold and you file a claim, the insurer may only pay a proportional share of the loss, even for partial damage. For example, if your home costs $400,000 to rebuild but you only carry $280,000 in coverage (70%), your insurer could reduce your payout proportionally. Always insure at 100% of replacement cost to avoid this penalty.
For personal property coverage (Coverage C), policies typically set this at 50% to 75% of your dwelling limit. If your home is insured for $400,000, your personal property coverage may default to $200,000 to $300,000. Create a home inventory to verify whether this amount is sufficient. High-value items like jewelry, fine art, firearms, and collectibles carry sub-limits (often $1,500 to $2,500 for theft) and typically require a separate scheduled personal property endorsement or floater to insure at their full appraised value.
For liability coverage (Coverage E), the III recommends considering limits higher than the standard $100,000 minimum. If you have significant assets, a $300,000 to $500,000 liability limit is more appropriate. Homeowners with substantial net worth should also consider an umbrella liability policy for additional protection.
Replacement Cost vs. Actual Cash Value: A Critical Distinction
How your insurer reimburses you after a claim depends on whether your policy uses replacement cost value (RCV) or actual cash value (ACV). Under RCV, the insurer pays the current cost to repair or replace the damaged item with materials of similar quality, without deducting for depreciation. Under ACV, the insurer subtracts depreciation from the payout, which can leave you with significantly less than what you need to rebuild or replace items.
Most HO-3 policies cover the dwelling and other structures at replacement cost by default, but personal property is often covered at actual cash value unless you pay extra to upgrade to RCV. Consider the difference: a five-year-old roof destroyed by hail might cost $15,000 to replace. Under RCV, you receive $15,000 minus your deductible. Under ACV, the insurer might subtract $5,000 in depreciation, leaving you with just $10,000 minus the deductible. Upgrading your personal property coverage to replacement cost is one of the most valuable policy additions you can make.
Named Perils: What Your Standard Homeowners Policy Covers
An HO-3 homeowners insurance policy provides open-peril coverage for the dwelling itself, meaning any cause of damage is covered unless specifically excluded. However, personal property is protected under a named-peril approach, covering only the 16 specific hazards listed in the policy. Understanding these perils helps you recognize exactly where your protection starts and stops.
The 16 Named Perils in a Standard HO-3 Policy
Property Damage Perils
- Fire or lightning
- Windstorm or hail
- Explosion
- Smoke
- Vandalism or malicious mischief
- Damage from aircraft
- Damage from vehicles
- Volcanic eruption
Additional Named Perils
- Riot or civil commotion
- Theft
- Falling objects
- Weight of ice, snow, or sleet
- Sudden and accidental water discharge (e.g., burst pipe)
- Accidental overflow from appliances
- Sudden electrical current damage
- Freezing of plumbing, HVAC, or sprinkler systems
It is important to note that even these covered perils come with conditions. Water damage from a burst pipe is covered, but only if it is sudden and accidental. A slow leak that develops over weeks or months and causes mold or structural damage is considered a maintenance issue and will be denied. Wind damage from storms is generally covered, but in hurricane-prone states like Florida, Louisiana, and South Carolina, your policy may include a separate, higher hurricane or wind deductible that is calculated as a percentage of your dwelling coverage rather than a flat dollar amount.
Important for Florida, Gulf Coast, and Atlantic Coast Buyers
In hurricane-prone regions, your homeowners insurance deductible for wind and hurricane damage is often 2% to 5% of your dwelling coverage, not the standard $1,000 to $2,500 flat deductible. On a $400,000 home, a 2% hurricane deductible means you are responsible for the first $8,000 of hurricane-related damage. Make sure you understand your wind/hurricane deductible before closing.
Coverage Gaps That Could Ruin You: What Homeowners Insurance Excludes
Standard homeowners insurance was never designed to cover every possible risk. Certain high-cost, region-wide catastrophes and maintenance-related issues are excluded from every standard policy. These exclusions represent the most dangerous gaps in homeowner protection, because many buyers assume they are covered until they file a claim and discover otherwise. The Insurance Information Institute and FEMA both emphasize that understanding these exclusions is essential for every property owner.
Flood Damage: The Most Dangerous Homeowners Insurance Gap
Flooding is the most common and costly natural disaster in the United States, and it is completely excluded from every standard homeowners insurance policy. This exclusion catches homeowners off guard because many do not realize that water from heavy rain pooling on their property, storm surge, river overflow, or rapid snowmelt are all classified as "flood" events that their policy will not cover.
According to FEMA, roughly 40% of National Flood Insurance Program (NFIP) claims come from properties located outside designated high-risk flood zones. The agency also reports that just one inch of floodwater in a typical home causes approximately $25,000 in damage. The average NFIP flood claim pays out approximately $68,000.
Flood insurance must be purchased as a separate policy through the National Flood Insurance Program or a private insurer. NFIP policies are available to anyone living in one of the more than 22,600 participating communities. The median annual cost for an NFIP policy is approximately $786. If your property is in a Special Flood Hazard Area and you have a federally backed mortgage, your lender will require flood insurance. But even if your home is in a moderate- or low-risk zone, the data strongly suggests you should consider purchasing coverage.
NFIP Coverage Limits
The National Flood Insurance Program caps coverage at $250,000 for the dwelling structure and $100,000 for contents. If your home's replacement cost exceeds these limits, consider supplementing with a private flood insurance policy, which often offers higher limits and additional features like coverage for temporary living expenses (which the NFIP does not provide).
Earthquake and Earth Movement Damage
Standard homeowners policies exclude all damage caused by earth movement, including earthquakes, landslides, sinkholes, and soil settlement. This affects homeowners well beyond California's fault lines. Seismic activity occurs in 45 states, and sinkhole risk is significant in Florida, Texas, Alabama, Missouri, Kentucky, Tennessee, and Pennsylvania.
Earthquake coverage is available as a separate policy or an endorsement to your homeowners policy. In California, the California Earthquake Authority (CEA) provides most residential earthquake coverage. Premiums vary widely based on your home's age, construction type, soil conditions, and proximity to known faults. In some sinkhole-prone states like Florida, insurers are required to make catastrophic ground cover collapse coverage available.
Sewer Backup and Sump Pump Failure
When a municipal sewer line backs up into your home or your sump pump fails during a storm, the resulting damage to flooring, walls, furniture, and personal belongings can easily reach $10,000 to $20,000. Standard homeowners insurance excludes this type of damage entirely, and flood insurance does not cover it either (unless the backup is a direct result of a covered flood event).
The good news: sewer backup endorsements are widely available and relatively inexpensive, typically adding $40 to $100 per year to your premium. This is one of the highest-value endorsements you can add to your policy, especially if your home has a basement, is connected to an older sewer system, or is in an area with mature trees whose roots can infiltrate sewer lines.
Mold Damage and Remediation Costs
Mold is covered only when it is a direct result of a covered peril. If a pipe bursts suddenly and mold develops from the water damage, your claim will likely include mold remediation. However, if mold grows due to high humidity, poor ventilation, gradual plumbing leaks, or deferred maintenance, the damage is excluded. Professional mold remediation can cost $1,500 to $30,000 depending on the extent of the problem.
Many policies now include a mold sub-limit (often $5,000 to $10,000) even for covered events. If you live in a humid climate or an older home, ask your insurer about a mold endorsement that provides higher limits.
Other Critical Homeowners Insurance Exclusions
| Exclusion | Why It Matters | Solution |
|---|---|---|
| Ordinance or Law | If your older home is damaged and must be rebuilt to current building codes, the additional cost is not covered under a standard policy. | Add an ordinance or law endorsement, especially for pre-1980 homes. |
| Service Line Coverage | Damage to underground utility lines (water, sewer, electrical) running from the street to your home is your responsibility, not the utility company's. | Add a service line endorsement (typically $50-$100/year). |
| Home Business | Standard policies provide little to no coverage for business equipment, inventory, or liability related to home-based businesses. | Add a home business endorsement or purchase a separate business owner's policy. |
| Dog Breed Restrictions | Certain dog breeds may void your liability coverage entirely or exclude bite-related claims. | Disclose all pets when purchasing. Consider a separate animal liability policy if your breed is restricted. |
| Trampoline/Pool Liability | These "attractive nuisances" may not be covered, and some insurers will cancel your policy if you install them without notification. | Notify your insurer, increase liability limits, and install required safety features (fences, covers). |

How to Reduce Homeowners Insurance Premiums Without Sacrificing Coverage
With premiums climbing year after year, homeowners are justifiably looking for ways to reduce costs. The key is to lower your premium without creating dangerous coverage gaps. Here are proven strategies, ranked by their typical impact on your annual premium.
High-Impact Strategies (10%-30% Savings Potential)
Shop Around and Compare Quotes
Premiums for the same home can vary by hundreds of dollars between insurers. Get quotes from at least three companies with identical coverage limits and deductibles for an accurate comparison. Independent insurance agents can access multiple carriers and often find rates that direct-to-consumer companies cannot match.
Bundle Your Policies
Purchasing your homeowners and auto insurance from the same carrier typically saves 10% to 25%, and some insurers offer up to 30% for multi-policy bundles. Adding an umbrella policy to the bundle can yield even greater savings. Before bundling, compare the bundled price against the total cost of separate best-rate policies to confirm you are actually saving money.
Raise Your Deductible
Increasing your deductible from $500 to $1,000 can lower your premium by approximately 25%, according to the Insurance Information Institute. Going from $1,000 to $2,500 can yield an additional 12% reduction. Make sure you have the higher deductible amount readily available in savings before making this change.
Medium-Impact Strategies (5%-15% Savings Potential)
Improve Your Home's Risk Profile
Installing safety and security features can earn meaningful discounts. Monitored burglar and fire alarm systems can reduce premiums by 15% to 20%. Deadbolt locks, smoke detectors, and water leak detection systems can each contribute an additional 2% to 5%. Impact-resistant roofing and storm shutters earn discounts in hurricane-prone regions.
Maintain Strong Credit
In most states, insurers use credit-based insurance scores as a factor in setting premiums. Homeowners with excellent credit pay significantly less than those with poor credit. Pay bills on time, keep credit utilization low, and check your credit reports regularly for errors. Note that California, Hawaii, Maryland, and Massachusetts prohibit insurers from using credit scores to set homeowners insurance rates.
Stay Claims-Free
Filing a claim can raise your premium by 6% or more, even for minor incidents. If the repair cost is close to your deductible, pay out of pocket. Maintaining a claims-free history for three to five years qualifies you for additional discounts at most carriers.
Additional Savings Opportunities
- Loyalty discounts: Staying with the same insurer for 3 to 5 years may earn a 5% discount; 6+ years can yield up to 10%.
- Retiree discounts: Homeowners 55 and older who are retired may qualify for up to 10% off.
- New home discounts: Recently built homes often qualify for lower rates due to updated wiring, plumbing, and building codes.
- Paperless and autopay discounts: Opting into electronic billing and automatic payments saves 2% to 5% with many carriers.
- Annual review: Review your policy every year. Remove coverage for items you no longer own, adjust other structures coverage if you have a small lot with minimal outbuildings, and confirm your dwelling limit matches current replacement costs.
Do Not Cut Coverage to Save Money
Reducing your dwelling coverage below 80% of replacement cost triggers a coinsurance penalty. Dropping liability below $100,000 leaves you personally exposed to lawsuits. Eliminating endorsements for real risks (like sewer backup) saves $50 to $100 a year but leaves you liable for $10,000+ in uncovered damage. Cut your premium through deductibles, discounts, and shopping around, never by reducing the coverage you actually need.
Getting Homeowners Insurance Before Closing: A Buyer's Timeline
Your lender will require proof of homeowners insurance before your closing date. Failing to secure a policy in time can delay or derail your closing entirely. Here is the timeline you should follow.
Weeks 3-4 Before Closing: Start Shopping
Begin gathering quotes as soon as your home inspection is complete. Use the inspection report to identify features that affect insurance (roof age, electrical system type, plumbing material, and the presence of a basement or pool). Get quotes from at least three insurers with identical coverage levels.
Weeks 2-3 Before Closing: Select and Bind Your Policy
Choose your insurer, select your coverage limits, and bind the policy. Your insurer will issue a binder as proof of insurance. Make sure the policy effective date aligns with your closing date, not the day after. Provide the binder to your lender and title company.
Week 1 Before Closing: Confirm and Verify
Verify that your lender has received the insurance binder and that the coverage amounts meet their requirements. Confirm that the first year's premium will be paid at closing (it is typically included in your closing costs) and that ongoing premiums are set up through your escrow account.
Flood Insurance Has a 30-Day Waiting Period
If you need flood insurance (either because your lender requires it or because your property faces flood risk), note that NFIP policies have a 30-day waiting period before coverage takes effect. The exception is when the policy is required as part of a mortgage closing, in which case it can take effect immediately. Start your flood insurance application as early as possible in the purchase process.
If you are evaluating a home inspection report, pay close attention to findings that affect insurability. Outdated electrical panels (Federal Pacific, Zinsco), polybutylene plumbing, wood-burning stoves without proper clearances, and roofs older than 20 years can all make it harder to obtain affordable coverage or may result in exclusions on your policy.

Find the Perfect Realtor®Homeowners Insurance Frequently Asked Questions
What does homeowners insurance cover?
A standard HO-3 homeowners insurance policy covers six areas: dwelling (Coverage A), other structures (Coverage B), personal property (Coverage C), loss of use (Coverage D), personal liability (Coverage E), and medical payments (Coverage F). The dwelling is covered on an open-peril basis, meaning all causes of damage are covered unless specifically excluded. Personal property is covered for 16 named perils including fire, theft, windstorm, and vandalism.
Does homeowners insurance cover flood damage?
No. Flood damage is excluded from every standard homeowners insurance policy. To protect against flooding, you must purchase a separate flood insurance policy through the National Flood Insurance Program (NFIP) or a private insurer. This is true regardless of whether your home is in a designated flood zone. According to FEMA, approximately 40% of NFIP claims come from properties outside high-risk flood areas.
Is earthquake coverage included in homeowners insurance?
No. Standard homeowners policies exclude damage from earthquakes and other earth movement events, including landslides, sinkholes, and soil settlement. Earthquake coverage must be purchased as a separate policy or added as an endorsement to your existing policy. In California, most residential earthquake coverage is provided through the California Earthquake Authority (CEA).
How much homeowners insurance do I need?
Your dwelling coverage should equal 100% of your home's replacement cost, which is the cost to rebuild the structure at current construction prices. This is different from your home's purchase price or market value. Most insurers require a minimum of 80% of replacement cost to avoid coinsurance penalties. Personal property coverage should cover the total value of your belongings, and liability coverage should be at least $100,000 but ideally $300,000 or more if you have significant assets.
What is the difference between replacement cost and actual cash value?
Replacement cost value (RCV) pays the current cost to repair or replace damaged property with similar materials and quality, without deducting for depreciation. Actual cash value (ACV) deducts depreciation based on the age and condition of the item, resulting in a lower payout. Most HO-3 policies cover the dwelling at replacement cost but cover personal property at actual cash value by default. Upgrading personal property to replacement cost coverage is one of the most valuable additions you can make to your policy.
Does homeowners insurance cover mold?
Mold is covered only when it results directly from a covered peril, such as water damage from a sudden pipe burst. Mold caused by humidity, poor ventilation, gradual leaks, or deferred maintenance is excluded. Many policies also impose mold sub-limits of $5,000 to $10,000 even for covered events. If you live in a humid climate or an older home, a mold endorsement can increase these limits for an additional premium.
How can I lower my homeowners insurance premium?
The most effective strategies include shopping around and comparing quotes from multiple insurers, bundling home and auto policies (10% to 25% savings), raising your deductible (switching from $500 to $1,000 can save approximately 25%), installing security systems and safety features (5% to 20% savings), maintaining strong credit, and staying claims-free. Review your policy annually to ensure you are not paying for unnecessary coverage or missing available discounts.
When do I need homeowners insurance for closing?
Your lender will require proof of homeowners insurance, typically in the form of an insurance binder, before closing. Start shopping for insurance 3 to 4 weeks before your closing date. Select and bind your policy 2 to 3 weeks before closing and provide the binder to your lender and title company. If you also need flood insurance, begin that process even earlier, as NFIP policies normally have a 30-day waiting period (waived when required for mortgage closings).
Homeowners insurance is one of the most important financial protections you will purchase as a property owner, but it only works if you understand exactly what it covers and what it does not. Use the coverage gap checklist in this guide to identify your specific risks, secure the right endorsements, and avoid the devastating surprise of a denied claim. Work with an experienced insurance agent, ask detailed questions about exclusions, and review your policy annually as your home, your belongings, and your risks evolve.
