HO-5 vs. HO-3 Homeowners Policies. What’s The Difference?

October 18th, 2017


Note: This discussion applies only to Insurance Services Office (ISO) coverage forms. These are used by most insurance companies in Maine. Some insurers (Allstate, State Farm, Travelers and more) use their own proprietary forms. If you have a quote or a policy from those companies, ask an agent to explain the coverage you’re buying.


All Maine homeowners policies are not created equal. In fact, if your policy is properly written, there may not be another like it. Common insurance policy forms have important differences, even though they look very similar.

HO3 vs. HO5

One key example is the difference between ISO HO-3 and HO-5 homeowners forms. The HO-3 was the most popular coverage form for decades. It covers a broad scope of building damages, but more limited coverage for your personal belongings.

A quick chart:




Open Perils – Covers any cause of loss unless excluded.

Named Perils –
Covers only damage from specified causes.



The HO-3 covers personal property against 16 named perils:

  1. Theft
  2. Fire or Lightning
  3. Freezing
  4. Windstorm or Hail
  5. Accidental Discharge or Overflow of Water from Plumbing
  6. Vehicles
  7. Smoke
  8. Weight of Ice, Snow, or Sleet
  9. Vandalism or Malicious Mischief
  10. Sudden & Accidental Tearing Apart, Cracking, Burning, or Bulging
  11. Sudden & Accidental Damage from Artificially Generated Electric Current
  12. Falling Objects
  13. Volcanic Eruption
  14. Riot or Civil Commotion
  15. Aircraft Damage
  16. Explosion

Why Buy HO-5 Instead of HO-3?

The open perils HO-5 form shifts the burden of proof from you to the insurance company. You’re not required to prove that the damage to your personal property was caused by one of the 16 named perils. It’s covered, unless it’s specifically excluded. Believe it or not, insurance adjusters like this, too. It removes a lot of the uncertainty and headache out of proving coverage.

What does an HO-5 Cover that an HO-3 Doesn’t?

Because the coverage is so broad, there are almost no limits to the ways your property could be damaged. Here are a few:

  • On a hot August day, a freak thunderstorm hits while you’re at work. Rain blows through an open window, damaging your home entertainment system.
  • At a dinner party, a guest spills a glass of red wine on your oriental carpet, damaging it.
  • A skunk finds its way through your open patio door. You startle it, and it sprays inside your home. All of your upholstered furniture must be deodorized.

Admittedly, these are not common claims. But clients often call insurance agents to report damage that’s NOT covered. Wouldn’t it be good to put the odds in your favor?


How Much Does It Cost?

The cost to upgrade from HO-3 to HO-5 varies by insurer. Believe it or not, sometimes, the HO-5 with one insurer may cost LESS than the HO-3 with another.  Often, insurers only offer HO-5 coverage for preferred properties and clients. That means you may qualify for very good pricing to begin with, which could save you money from your current HO-3 policy. If you qualify for both forms, the HO-5 is the preferred option.
