🏗 What Is Buildings Declared Value (BDV)?

“Buildings Declared Value” is the value that you declare (often when taking out a policy) representing what it would cost to rebuild the structure of your home (or building), including things like:

  • Fitted kitchens, bathrooms, and permanent fixtures
  • Demolition, debris removal, site clearance
  • Architect, engineering or planning fees
  • Costs associated with current construction standards

It does not include the value of the land, or the market value of the property. It’s strictly replacement cost of the structure. (Deacon)


⚠️ Why Does BDV Matter?

Using the correct BDV in your policy is very important because:

  • If your declared value is set too low, you can be underinsured. That means in a total loss, you might not receive enough money to rebuild.
  • Many policies have “index link” or inflationary adjustments to BDV, helping the value keep up with material costs and labor increases over time. (Deacon)
  • Claims can be reduced proportionally if the declared value is significantly under what is actually needed. (Some policies may have “average clause” provisions.)

🔍 Is “BDV Insurance” a Product?

If someone refers to “BDV insurance,” they might mean:

  • A policy that requires you to declare the building replacement value (BDV) explicitly.
  • Or ensuring the “sum insured” or coverage limit is based on BDV (sometimes called “day one replacement cost” or “full rebuild cost”).

It’s not usually a separate kind of insurance by itself—it’s more about how the insurer values your building for coverage.


âś… Bottom Line

  • BDV (Buildings Declared Value) refers to the value assigned to the home’s structure for rebuilding purposes—not the land or resale value.
  • Making sure your BDV is accurate is crucial to avoid being underinsured.
  • If you see “BDV insurance,” clarify with your agent whether it means your policy uses declared value as the basis for dwelling coverage.
