A standard homeowners policy (HO-3) isn't one coverage — it's six coverages bundled into a single policy. Understanding each one tells you exactly when you're protected and when you're not.
Coverage A: Dwelling (Your Home's Structure)
This is the core of your policy. It covers physical damage to your home's structure: walls, roof, foundation, attached garage, built-in appliances, and permanently installed fixtures.
What triggers Coverage A:
- Fire and smoke damage
- Lightning strikes
- Wind and hailstorm damage
- Explosion
- Vandalism
- Falling objects (tree through roof)
- Weight of ice, snow, or sleet
- Accidental water overflow (burst pipe, not flood)
- Riot or civil commotion
Coverage amount: Should equal your home's replacement cost — what it would cost to rebuild from scratch at current construction prices. This is often different from market value. A home worth $400,000 on the market might cost $350,000 to rebuild, or $550,000 in a high-labor-cost area.
Coverage B: Other Structures
Covers structures on your property that aren't attached to your main house:
- Detached garage, workshop, or carport
- Fence, retaining walls, driveway
- Swimming pool, hot tub, gazebo
- Shed, barn, or guest house
Standard amount: 10% of your dwelling coverage. If you have $300,000 in Coverage A, you have $30,000 for other structures. If you have a large detached garage or guest house, you may need to increase this limit.
Note: Structures used for business purposes on your property (a shop, rental unit) may not be fully covered under Coverage B.
Coverage C: Personal Property (Your Belongings)
This covers your stuff — everything that's not attached to the house:
- Furniture, electronics, clothing, appliances
- Kitchen items, tools, sports equipment
- Items in storage units or away from home
- Your belongings while traveling
Standard amount: 50–70% of dwelling coverage. On a $300,000 policy, that's $150,000–$210,000 in personal property coverage.
Critical Sub-Limits to Know
Even within Coverage C, certain categories have built-in dollar caps:
- Jewelry: $1,500 per item/$2,500 total (for theft) — engagement rings worth $8,000 are NOT fully covered without a floater
- Cash and currency: $200 limit
- Securities and financial instruments: $1,000–$2,500
- Firearms and accessories: $2,500
- Silverware: $2,500
- Electronics and computers: Usually no sub-limit but covered perils apply
- Artwork and collectibles: May have limits or exclusions — requires scheduled endorsement for high-value pieces
For items above these limits, you need a personal articles floater or scheduled endorsement.
Replacement Cost vs. Actual Cash Value
How your personal property claim gets paid is critically important. Check your policy:
- Replacement Cost Value (RCV): Pays what it costs to buy a new equivalent item today. Your 3-year-old $1,500 laptop gets replaced with a current $1,200 model — you get $1,200.
- Actual Cash Value (ACV): Pays replacement cost minus depreciation. That laptop might be worth $400 under ACV. You get $400 — not enough to buy a new one.
Always upgrade to replacement cost for personal property. The additional premium is usually $30–$60/year.
Coverage D: Additional Living Expenses (ALE)
If a covered loss makes your home temporarily uninhabitable, ALE pays for:
- Hotel or temporary rental costs
- Restaurant meals above your normal food budget
- Laundry, storage, and pet boarding
- Extra commuting costs
Why it matters: A major house fire can leave you displaced for 6–18 months during reconstruction. Hotel costs alone run $3,000–$5,000/month in most markets. ALE typically covers 20–30% of your dwelling coverage — make sure that's enough for your area.
Coverage E: Personal Liability
If someone is injured on your property or you accidentally damage someone else's property, liability coverage pays for:
- The injured party's medical bills and lost wages
- Your legal defense costs if they sue you
- Any judgment or settlement — up to your limit
- Damage you or your family members cause to others' property
Standard coverage: $100,000 — but this is often too low. A serious slip-and-fall lawsuit or dog bite injury can easily exceed $100,000. Consider $300,000 or $500,000 for minimal additional premium. If your net worth exceeds $500,000, add a personal umbrella policy.
Coverage F: Medical Payments to Others
This "good neighbor" coverage pays for minor medical bills of guests injured on your property, regardless of who was at fault. If a friend trips on your porch and needs stitches, Medical Payments handles their ER bill without requiring a formal liability claim.
- Standard limit: $1,000–$5,000 per person
- Why it matters: Keeps small incidents from becoming liability claims, which affect your premiums
What Homeowners Insurance Does NOT Cover
This is where most homeowners get surprised. Standard HO-3 policies specifically exclude:
Floods
The #1 most misunderstood exclusion. Damage from rising water, storm surge, overflowing rivers, or heavy rain accumulation is NOT covered by homeowners insurance. You need a separate flood policy through the National Flood Insurance Program (NFIP) or a private flood carrier. Over 25% of flood claims come from properties outside high-risk flood zones.
Earthquakes
Earthquake damage is excluded in standard policies. You need a separate earthquake endorsement or policy. Critical in California, the Pacific Northwest, the New Madrid Seismic Zone (MO, IL, TN, AR), and parts of Alaska.
Sewer Backup
When your sewer or drain backs up into your home, standard policies don't cover the damage. A sewer backup endorsement costs only $40–$100/year and covers $10,000–$25,000 in cleanup and damage. Worth adding to every policy.
Mold from Neglect
Mold that results from a covered sudden water loss (burst pipe) is typically covered. Mold that develops because you ignored a slow leak for months is not — that's a maintenance issue, not an insured event.
Normal Wear and Tear
Insurance covers sudden, accidental events — not gradual deterioration. Your 25-year-old roof that finally fails from age isn't covered. Your HVAC system that dies from old age isn't covered. These are maintenance issues.
Pest Damage
Termites, carpenter ants, rodents, birds — all excluded. Pest control and resulting damage repair is your responsibility. Termite damage alone causes $5 billion in U.S. property damage annually, none of it covered by homeowners insurance.
Home-Based Business Liability
If a client visits your home office and injures themselves, or if your business activities cause property damage, standard homeowners liability doesn't cover it. Business liability requires a separate endorsement or business policy.
Coverage Gaps to Address Now
The most important gaps to plug in your current policy:
- Flood insurance: Even if you're not in a flood zone — climate change is shifting flood risk maps
- Sewer backup endorsement: $40–$100/year, protects against disgusting and expensive damage
- Jewelry/valuables floater: If you have jewelry, art, or collectibles worth more than policy sub-limits
- Identity theft coverage: Many insurers offer this as an endorsement
- Higher liability limits: Standard $100K is rarely enough — go to $300K+

Bottom line: Your homeowners policy provides strong protection for fire, wind, theft, and liability — but it has real gaps. Flood, earthquake, sewer backup, and home business liability are the most commonly missed exclusions. Review your policy annually, plug the gaps with endorsements, and make sure your coverage limits reflect current replacement costs.
