Key Takeaways

  • DP-1 (Basic Form) provides named perils coverage only — the most limited and least expensive dwelling form
  • DP-2 (Broad Form) covers more named perils than DP-1 and includes theft coverage — moderate protection and cost
  • DP-3 (Special Form) provides open perils coverage for the dwelling and named perils for personal property — most comprehensive
  • As you move from DP-1 to DP-3, coverage expands and premiums increase proportionally
  • DP-3 is similar to HO-3 in coverage structure — open perils on building, named perils on contents

Dwelling Policy Forms (DP-1, DP-2, DP-3)

The Insurance Services Office (ISO) developed three standardized dwelling policy forms, each offering different levels of protection. Understanding the differences is heavily tested on the P&C exam.

The Three Dwelling Forms at a Glance

DP-2Broad FormNamed Perils (more)Named PerilsModerateRentals, seasonal homes
DP-3Special FormOpen PerilsNamed PerilsHighestMaximum landlord protection

DP-1: Basic Form

The Most Limited Coverage

Covered Perils (Named Perils Only)

The DP-1 covers these specific perils:

  • Fire or lightning
  • Internal explosion
  • Windstorm or hail (exterior damage only)
  • Explosion
  • Riot or civil commotion
  • Aircraft
  • Vehicles
  • Smoke
  • Volcanic eruption

Key Limitations

  • NO theft coverage — Major gap in protection
  • Pays losses on Actual Cash Value (ACV) basis only
  • Limited water damage coverage
  • No coverage for falling objects, ice/snow/sleet weight

When to Use DP-1

  • Vacant properties needing minimal coverage
  • Very low-value structures
  • Properties requiring only basic fire protection
  • Budget-conscious coverage

Exam Tip: DP-1 does NOT cover theft. This is a key distinction from DP-2 and DP-3.


DP-2: Broad Form

Enhanced Named Perils Coverage

Covered Perils (Expanded List)

DP-2 includes all DP-1 perils PLUS:

  • Theft — Major addition from DP-1
  • Falling objects
  • Weight of ice, snow, or sleet
  • Accidental discharge of water or steam
  • Freezing of plumbing, heating, or AC
  • Sudden and accidental damage from electrical current
  • Volcanic eruption damage

Key Features

  • Broader peril coverage than DP-1
  • Theft coverage included
  • ACV or Replacement Cost available (with endorsement)
  • Good balance of coverage and cost

When to Use DP-2

  • Rental properties
  • Seasonal/vacation homes
  • Secondary residences
  • Properties needing theft coverage but not full open perils

DP-3: Special Form

The Most Comprehensive Dwelling Policy

Exam Tips

  1. DP-1 does NOT cover theft — Most frequently tested difference
  2. DP-3 = Open perils on building, Named perils on contents
  3. None of the DP forms include liability — That requires an endorsement or separate policy
  4. The progression DP-1 → DP-2 → DP-3 means MORE coverage and MORE cost
