HO-3 vs HOB Home Insurance in Texas | Coverage Differences

An HO-3 and a traditional Texas HOB policy can both provide broad "open-peril" coverage on the home itself, but they are not identical policies. The covered losses, exclusions, water provisions, contents coverage, endorsements, and claim settlement terms can differ.

That means you should not assume an HOB is automatically better than every HO-3 — or that every HO-3 provides the same protection.

TWFG Elkhalil Insurance helps homeowners compare Houston homeowners insurance options by looking at the actual policy form, deductibles, roof settlement, water coverage, and endorsements rather than the premium alone.

What is an HOB homeowners policy in Texas?

The HOB is a traditional Texas homeowners policy form that has historically been widely used for owner-occupied homes.

TDI describes the HOB as providing:

• Open-peril coverage for the building, meaning covered unless a cause of loss is specifically excluded
• Named-peril coverage for personal property
• Liability protection
• Additional coverage subject to the policy's terms and exclusions

Texas also historically had HOA and HOC policy forms, with HOB positioned as the broader middle form and HOC as the broadest traditional Texas form.

What is an HO-3 homeowners policy?

HO-3 is a homeowners form developed by ISO, a national insurance advisory organization.

TDI's current residential reporting rules recognize the ISO HO 00 03 as the Homeowners 3 – Special Form.

Like the traditional HOB, an HO-3 generally uses:

• Open-peril coverage for the dwelling
• Named-peril coverage for personal property
• Personal liability coverage
• Additional coverages and exclusions defined by the policy and endorsements

However, the exact HO-3 offered by a Texas carrier may include endorsements or company-specific changes.

HO-3 vs. HOB at a glance

What does "open peril" mean?

Open-peril coverage means the dwelling is generally covered for direct physical loss unless the cause of loss is specifically excluded or limited by the policy.

TDI uses the phrase "all risk" in some older educational materials, but "open peril" is often clearer because no homeowners policy literally covers every possible loss.

Common exclusions can include:

• Flood
• Earth movement
• Wear and tear
• Maintenance-related damage
• Insects or vermin
• Certain mold or fungus losses
• Continuous or repeated leakage depending on the form
• Other policy-specific exclusions

What does "named peril" mean for personal property?

Named-peril coverage means personal property is generally covered only when the loss is caused by a peril specifically listed in the policy.

Examples commonly found in homeowners forms can include:

• Fire
• Lightning
• Windstorm
• Hail
• Theft
• Vandalism
• Falling objects
• Certain sudden water losses
• Other listed causes of loss

The exact list depends on the form.

Is an HOB broader than an HO-3?

Historically, the traditional Texas HOB was broader than the ISO HO-3 in several specific areas.

TDI performed side-by-side comparisons when ISO homeowners forms entered the Texas market and identified both restrictions and enhancements in the ISO HO-3 compared with the traditional HOB.

That is important because the answer is not simply:

"HOB is always better."

There were areas where the HO-3 was narrower and areas where it provided different or enhanced protection.

Modern carrier endorsements make the comparison even more policy-specific.

One of the biggest differences to compare: water coverage

Water damage is one of the most important areas to examine when comparing Texas homeowners policies.

TDI's historical comparison between ISO HO-3 and HOB identified differences in water-related provisions.

Today, individual carriers can also modify water coverage through endorsements.

Ask how the policy treats:

• Sudden plumbing leaks
• Burst pipes
• Accidental discharge of water
• Repeated leakage or seepage
• Water backup
• Foundation-related water damage
• Mold resulting from a covered water loss

Does HO-3 cover foundation damage?

Do not assume foundation coverage based solely on the HO-3 label.

Foundation movement, settling, cracking, and earth movement can be excluded or limited.

Some Texas carriers may offer endorsements that provide certain foundation-related coverage connected to covered plumbing losses, while others may not.

The same caution applies to HOB policies: the current policy language and endorsements control.

Which policy is better for water leaks?

The policy with broader applicable water provisions is better for that specific exposure — regardless of whether the label says HO-3 or HOB.

Compare:

• Sudden discharge coverage
• Long-term leakage limitations
• Foundation provisions
• Water backup
• Mold limits
• Resulting damage language

Our guide on what homeowners insurance covers in Texas provides broader context on common covered losses.

Does HOB automatically have replacement-cost roof coverage?

No.

Do not assume roof replacement cost from the policy-form name alone.

Modern policies can include endorsements that change roof settlement to:

• Replacement cost
• Actual cash value
• A roof payment schedule
• Another policy-specific settlement method

The same is true for HO-3 policies.

See our replacement cost vs. actual cash value roof coverage guide .

Can an HO-3 actually be broader than an HOB?

In certain areas, yes.

A modern HO-3 with strong endorsements can provide broader protection in some areas than another policy labeled HOB.

Likewise, an HOB with favorable provisions may be broader in important areas than a more restrictive HO-3.

This is why comparing form names alone can be misleading.

Example: Two policies that look similar but are not

Consider these hypothetical Houston quotes:

In this hypothetical example, simply choosing the HOB because it sounds broader would miss several important differences.

The example is illustrative only and is not intended to represent every HO-3 or HOB policy.

Another example: The HOB could still be the stronger option

Now reverse the situation:

In this example, the HOB costs more but may offer substantially stronger protection.

Again, the point is that the actual coverage wins — not the label.

Are all HO-3 policies the same?

No.

This is extremely important in Texas.

TDI's current statistical plan recognizes ISO HO-3 as one form but also recognizes independently filed homeowners forms.

Carriers can file their own forms and endorsements with TDI, which means two companies can offer policies that are both marketed as homeowners coverage while containing different exclusions or enhancements.

TDI notes that policy-form filings and supporting information are available for public inspection. :contentReference[oaicite:1]{index=1}

Are all HOB policies the same?

Not necessarily.

The traditional Texas HOB is a specific historical form, but companies may use endorsements or independently filed versions that modify coverage.

The declarations page, base policy form, and endorsements should all be reviewed together.

What does Texas use today: HOB or HO-3?

Texas allows multiple homeowners forms in the market.

TDI's current residential statistical plan recognizes the traditional Texas forms, ISO forms such as HO-2, HO-3, HO-5, and multiple categories for independently filed homeowners policies. :contentReference[oaicite:2]{index=2}

So there is not one single statewide homeowners policy that every Texas company must sell.

Should you pay more for an HOB?

Only if the additional premium buys meaningful coverage you value.

For example, suppose:

• HO-3 premium: $4,000
• HOB premium: $4,500

The $500 difference is impossible to evaluate without knowing whether the policies differ in:

• Wind and hail deductible
• Roof settlement
• Water coverage
• Foundation provisions
• Personal property settlement
• Liability limits
• Endorsements
• Exclusions

Which matters more: HOB vs. HO-3 or the deductible?

Both matter.

A broad policy with a very high deductible can still create significant out-of-pocket exposure.

For example, on a $500,000 home:

• 1% deductible = $5,000
• 2% deductible = $10,000
• 3% deductible = $15,000
• 5% deductible = $25,000

Compare the form and the deductible together.

See our Houston wind and hail deductible guide .

What should you compare on an HO-3 vs. HOB quote?

Use this checklist:

1. Dwelling coverage
2. Wind and hail deductible
3. Other deductibles
4. Roof settlement
5. Sudden water damage
6. Repeated leakage or seepage
7. Foundation-related provisions
8. Water backup
9. Personal property settlement
10. Liability limits
11. Replacement-cost provisions
12. Endorsements
13. Exclusions
14. Annual premium

Which Houston carriers may use different homeowners forms?

Policy forms vary by carrier, program, eligibility, and current availability.

Depending on the property, TWFG Elkhalil Insurance may compare homeowners options from markets such as:

• Travelers
• Mercury
• SageSure programs
• Homeowners of America
• Chubb
• Other available Texas homeowners insurance markets

The goal is not to force every home into one form. It is to compare the coverage that is actually available for the property.

Why use an independent insurance agency for an HO-3 vs. HOB comparison?

An independent insurance agency can compare available policies from multiple markets rather than showing only one carrier's form.

TWFG Elkhalil Insurance helps Houston homeowners compare:

• Policy forms
• Premiums
• Deductibles
• Roof settlement
• Water coverage
• Replacement-cost provisions
• Liability
• Endorsements
• Exclusions

That makes the comparison more useful than simply asking whether "HOB" or "HO-3" sounds better.
