Key Takeaways

A standard homeowners policy typically covers your dwelling, other structures, personal property, liability, and additional living expenses.
Flood and earthquake damage are almost universally excluded from standard policies and require separate coverage.
Personal property is usually insured at actual cash value unless you upgrade to replacement cost coverage.
High-value items like jewelry, art, and collectibles often have sub-limits and may need a scheduled endorsement.
Routine wear and tear and maintenance-related damage are never covered by homeowners insurance.
Always read your declarations page and policy exclusions carefully before assuming a loss is covered.

Homeowners Insurance

Homeowners insurance is a property insurance policy that protects your home, the structures on your property, your personal belongings, and your financial liability if someone is injured on your premises. Most US mortgage lenders require it as a condition of your loan. A standard policy bundles several types of coverage under one contract, though the specific terms vary by insurer and state.

The most common policy form in the US is the HO-3, which covers the dwelling on an open-perils basis (all causes of loss except those specifically excluded) and personal property on a named-perils basis (only the causes listed in the policy).

What a Standard Policy Actually Covers

A typical HO-3 homeowners policy is organized into six main coverage categories. Understanding each one helps you know exactly what protection you're paying for.

  • Dwelling (Coverage A): Pays to repair or rebuild your home's structure — walls, roof, foundation, and built-in appliances — if damaged by a covered peril such as fire, windstorm, or vandalism.
  • Other Structures (Coverage B): Covers detached garages, fences, sheds, and similar structures. Usually capped at 10% of your dwelling limit.
  • Personal Property (Coverage C): Reimburses you for furniture, electronics, clothing, and other belongings damaged or stolen. Coverage is often on an actual cash value basis, which factors in depreciation — upgrading to replacement cost coverage closes that gap.
  • Loss of Use (Coverage D): Covers hotel stays, restaurant meals, and other additional living expenses if a covered loss forces you temporarily out of your home.
  • Personal Liability (Coverage E): Protects you if someone is injured on your property or if you accidentally damage someone else's property. It also covers legal defense costs.
  • Medical Payments (Coverage F): Pays limited medical bills for guests injured at your home, regardless of who is at fault — typically between $1,000 and $5,000.

Review Your Coverage Limits Annually

Construction costs and home values shift over time, and a dwelling limit that was adequate several years ago may fall short today. Review your policy limits each year at renewal and consider asking your insurer about an inflation guard endorsement, which automatically adjusts your dwelling coverage to keep pace with rising rebuild costs.

Common Exclusions You Should Know

Homeowners insurance exclusions are where many owners are caught off guard. The following are among the most significant gaps in a standard policy.

Actual Cash Value vs. Replacement Cost

These two valuation methods produce very different claim payouts. Actual cash value (ACV) deducts depreciation from the item's original cost — a five-year-old laptop might be reimbursed at a fraction of what a new one costs. Replacement cost value (RCV) pays what a comparable new item costs today. Check your policy declarations page to confirm which method applies to your personal property coverage.

  • Flood damage: Water from rising rivers, storm surge, or heavy surface runoff is excluded from standard policies. The NFIP and some private insurers offer standalone flood policies.
  • Earthquakes and earth movement: Ground shifting, sinkholes, and seismic events require a separate earthquake endorsement or policy — particularly important in high-risk states like California and Oregon.
  • Maintenance and wear and tear: Damage from neglected upkeep — a rotting roof, gradual pipe corrosion, pest infestation — is considered a maintenance issue, not an insurable loss.
  • Sewer backup: Unless you add a sewer or water backup endorsement, damage from a backed-up drain or sump pump is typically excluded.
  • High-value personal property: Standard policies impose sub-limits on jewelry, fine art, firearms, and collectibles — often as low as $1,500 for theft of jewelry. A scheduled personal property endorsement can provide fuller coverage.

Homeowners insurance also differs significantly from a home warranty. For a side-by-side comparison, see home warranty vs. homeowners insurance.

Add-On Options and Endorsements Worth Considering

Most insurers allow you to customize a standard policy with endorsements (also called riders or floaters) that fill specific gaps. Common options include:

  • Replacement cost on personal property: Pays what it costs to buy a comparable new item today, rather than depreciated value.
  • Extended or guaranteed replacement cost on the dwelling: Provides a cushion above your policy limit if rebuild costs spike after a widespread disaster.
  • Flood insurance: Required separately; available through the NFIP or private carriers depending on your location.
  • Earthquake endorsement: Often available as a policy add-on in seismically active regions.
  • Water backup coverage: Adds protection for sewer line backups and sump pump failures.
  • Scheduled personal property: Insures high-value individual items at their appraised value.
  • Home business endorsement: Extends limited coverage to business equipment and liability for home-based workers.

Coverage B for detached garages, fences, and sheds is typically set at 10% of the dwelling coverage amount in a standard HO-3 policy.

Deciding which endorsements make sense depends on your home's location, age, and contents.
