HO-3 Home Insurance Policy: What You Need to Know

An HO-3 policy is the most common form of homeowners insurance in the U.S., and most mortgage lenders require it. The policy covers your home and other structures on an open perils basis: it protects against any cause of damage except what the policy excludes by name. Your belongings get named perils coverage only, so the policy pays out only for the perils it lists.

If a car crashes into your fence, an HO-3 policy covers the structural damage because the dwelling has open perils protection. If a flood damages your belongings and flood isn't a named peril in your policy, you pay for those losses out of pocket.

An HO-5 policy covers both your home and your belongings on an open perils basis. That broader protection comes with a higher premium than a standard HO-3.

Most homeowners with a mortgage need an HO-3 because lenders require it as a loan condition. Homeowners who own their home outright still benefit from an HO-3. It's the baseline coverage level for what's usually a household's largest single asset.

An HO-3 covers your house and other structures against nearly all causes of damage. Personal belongings are covered only for events named in the policy. An HO-3 includes:

HO-3 coverage splits into two types. Your home and other structures get open perils protection; your personal property gets named perils protection. That split decides whether you pay out of pocket after a loss.

The named vs. open perils distinction matters most in gray-area situations. A burst pipe from sudden freezing is a named peril and would be covered, but a slow leak that causes mold over six months may be classified as neglect or maintenance failure, which is excluded under open perils. A windstorm that tears off your roof is covered under open perils for the dwelling, but if rainwater then causes damage to your furniture, that furniture claim goes through named perils coverage, where wind is listed.

Your home's structure has strong protection under an HO-3, but your belongings have gaps. Homeowners with expensive personal property should either add a scheduled personal property rider or consider upgrading to an HO-5 policy.

The average annual cost of an HO-3 policy depends on your coverage limits. For a policy with $250,000 in dwelling coverage, rates average $292 per month or $3,503 per year, based on MoneyGeek's analysis of rate filings from Quadrant Information Services.

When we compared costs across five coverage tiers, one pattern was clear: higher dwelling limits cost less per dollar of protection. At $100,000 in dwelling coverage, you pay $18.48 per $1,000 of coverage. At $1 million, that drops to $10.79 per $1,000. That's a 42% reduction in your per-dollar rate. Homeowners who need $500,000 or more in dwelling coverage get better value per dollar than those at the lower tiers.

Going from $100,000 to $250,000 in dwelling coverage adds $1,655 a year, a 90% cost increase for 150% more coverage. Moving from $250,000 to $500,000 adds $2,436 a year, a 70% cost increase that doubles dwelling coverage and raises liability from $200,000 to $300,000.

For homeowners whose replacement cost falls between tiers, the math favors rounding up: the marginal cost of each additional coverage increment decreases at every step.

The cost of an HO-3 policy varies widely by company. In our analysis, AIG is the cheapest HO-3 provider for $250,000 in dwelling coverage at an average of $91 per month ($1,093 per year). Nationwide averages $279 per month ($3,346 per year) for the same coverage level. Nationwide's rate is more than three times AIG's rate.

That $188 monthly difference between the cheapest and most expensive provider adds up to $2,256 per year for the same $250,000 dwelling coverage. But the cheapest rate isn't always the best value. AIG and CSAA both have limited geographic availability. AIG writes policies primarily through independent agents in select states. CSAA limits membership to certain regions. Amica, at $117 per month, is available in most states and has ranked among the highest insurers for claims satisfaction. The $26 monthly gap between AIG and Amica, $312 per year, buys broader availability and a better claims record.

Homeowners who qualify for AAA membership can access its $143 monthly rate, which includes member-only discounts. American Modern, at $175 per month, specializes in non-standard properties: older homes, vacant properties and homes with unique construction. Other insurers may decline coverage or charge more.

Picking the right coverage level starts with your home's replacement cost, which is what it would cost to rebuild your home from the ground up at today's construction prices. This is not the same as your home's market value or your mortgage balance.

Don't underinsure to save money. If a covered loss exceeds your dwelling limit, you pay the difference. Rebuilding costs have risen sharply in recent years due to labor shortages and material prices, so a home that cost $250,000 to build in 2010 may cost $350,000 or more to rebuild today. Ask your insurer about guaranteed replacement cost or extended replacement cost endorsements, which pay above your dwelling limit if rebuilding costs exceed your coverage.

The cost of an HO-3 policy varies, but there are ways to lower your premium without giving up important coverage.

• Bundle your home and auto policies. Most insurers give 10% to 25% off when you combine home and auto policies. On a $3,503 annual HO-3 premium, a 15% bundling discount saves roughly $525 per year. This is the single largest discount available to most homeowners.
• Raise your deductible. Moving from a $1,000 deductible to a $2,500 deductible usually lowers your annual premium by 10% to 15%. On the average $3,503 HO-3 policy, that's $350 to $525 in annual savings. But this trade-off only works if you can cover $2,500 out of pocket when you file a claim. Homeowners in hail-prone or storm-prone areas who file small claims regularly may find the savings don't offset the higher out-of-pocket cost.
• Add safety features. Security systems, smoke detectors, deadbolt locks and storm shutters can each reduce your premium by 2% to 10%. Some insurers offer specific programs for connected home devices. Ask about smart home or protective device credits by name.
• Stay claims-free. Filing fewer claims signals lower risk to your insurer. Many companies offer claims-free discounts of 5% to 20% after three to five years without a claim. Before filing a small claim, compare the payout to the potential premium increase. A $1,500 claim that raises your rate by $300 per year for three to five years costs more than it pays.
• Shop around every two to three years. Our data shows the cheapest insurer for one homeowner profile isn't the cheapest for another. Rate competitiveness changes as insurers adjust their underwriting models. Comparing quotes from at least three companies is the most reliable way to get the cheapest home insurance for your needs.

HO-3 is the most common type of homeowners insurance, but other policy forms provide different levels of protection. Here's how they compare:

The most common decision point for homeowners is HO-3 vs. HO-5. An HO-3 covers your home on an open perils basis but limits personal property to named perils. An HO-5 extends open perils coverage to your belongings, too. You're covered for damage from any cause unless the policy excludes it by name.

HO-5 policies cost 5% to 15% more than an equivalent HO-3. That premium closes gaps that catch homeowners off guard, like accidental damage to electronics or a mysteriously missing item. If you own expensive personal property and want fewer exclusions, price out the HO-5 upgrade before you buy.

An HO-3 policy is the standard homeowners insurance required by most mortgage lenders, covering your home on an open perils basis and your belongings for named perils. The average cost is $3,503 per year for $250,000 in dwelling coverage, but rates range from $1,093 (AIG) to over $3,346 (Nationwide) for the same protection level.

Start by estimating your home's replacement cost (not its market value) and choose a dwelling limit that covers at least 80% of that figure. Compare quotes from at least three insurers, because our data shows the spread between cheapest and most expensive provider is $2,256 per year. Ask about bundling, claims-free and protective device discounts by name. And review your policy's exclusions for flood, earthquake and high-value item sub-limits. These are the gaps that cost homeowners the most when a claim occurs.

Here are common questions about HO-3 homeowners insurance policies, including what they cover, how they compare to other types and when you might need extra protection.

MoneyGeek evaluated homeowners insurance companies using premium data and analysis from Quadrant Information Services. We based our insights on thousands of rate filings from insurers across the U.S., allowing us to provide accurate comparisons grounded in real-world pricing.

We used a sample homeowner profile with a good credit score (769 to 792), a wood-frame house built in 2000 and a composite shingle roof for consistency. Standard quotes reflected $250,000 in dwelling coverage, $125,000 in personal property, $200,000 in liability and a $1,000 deductible.
We also analyzed policies with $1 million in dwelling coverage, $500,000 in personal property and $1 million in liability to assess coverage options for higher-value homes. All rates reflect the annual premium divided by 12 for monthly figures, rounded to the nearest whole dollar per MoneyGeek's editorial standards.

Our analysis focused on comparing rates at identical coverage levels across insurers to give homeowners an apples-to-apples view of pricing. We calculated per-dollar coverage costs at each tier to identify where homeowners get the best value, and we reviewed the geographic availability and specialization of each insurer to flag limitations that affect who can access the cheapest rates.
