Delaware Dwelling and Commercial Property Insurance

Dwelling policies provide coverage for rental properties and homes not eligible for homeowners insurance. Commercial property insurance protects business buildings, contents, and operations from property losses.

Dwelling Policies

Purpose of Dwelling Policies

Dwelling policies cover:

  • Rental properties (landlord owns, doesn't occupy)
  • Vacant or unoccupied homes
  • Homes under renovation
  • Properties not eligible for homeowners policies
  • Seasonal homes (in some cases)

NOT for:

  • Owner-occupied primary residences (use homeowners policy)
  • More than 4 family units (use commercial property insurance)

Coinsurance in Commercial Property

Coinsurance Requirement

Purpose:

  • Encourages policyholders to insure to adequate limits
  • Penalties for underinsurance
  • Ensures fair premium distribution

Common Coinsurance Percentages:

  • 80%: Most common for commercial property
  • 90% or 100%: Higher coinsurance = lower premiums

Coinsurance Formula

If property is underinsured (below coinsurance requirement):

Insurance Payment=Amount of Insurance CarriedAmount of Insurance Required×Loss Amount\text{Insurance Payment} = \frac{\text{Amount of Insurance Carried}}{\text{Amount of Insurance Required}} \times \text{Loss Amount}

Where: \text{Amount Required} = \text{Property Value} \times \text{Coinsurance %}

Coinsurance Example

Scenario:

  • Building value: $1,000,000
  • Coinsurance requirement: 80%
  • Insurance carried: $600,000
  • Loss: $200,000

Required Insurance:

  • $1,000,000 × 80% = $800,000

Coinsurance Penalty Applies (insured only $600,000, needed $800,000):

Payment Calculation:

  • $600,000 (carried) ÷ $800,000 (required) × $200,000 (loss) = $150,000 paid
  • Policyholder receives $150,000, not full $200,000

Coinsurance Penalty:

  • Underinsurance penalty: $50,000

Exam Tip: Coinsurance penalizes underinsurance in commercial property. If you don't carry insurance equal to the coinsurance percentage of the property value, you become a co-insurer and share in the loss. Always insure to at least the coinsurance requirement to avoid penalties.
