TDR Market Information

Just as with other commodity markets like food and oil, the Transfer of Developments or TDR "market," is driven by supply and demand. Landowners of sending sites create the supply of development rights when they choose to put a conservation easement on their property in exchange for TDRs to sell and transfer to other areas. Developers using development rights to increase density at receiving sites create the demand. To see TDRs currently for sale, check out the TDR Exchange.

The market price of TDRs is set by four factors:

  1. The price individual developers are willing to pay for a TDR – that is, an increment of density such as an additional unit/house in their development project. This will vary by location and development project;
  2. The price at which individual rural landowners are willing to sell their transferable development rights;
  3. The amount of TDRs readily available in King County’s Program (i.e. the landowner TDR supply);
  4. The development industry’s interest in buying additional density in King County (i.e. developer TDR demand)

TDR prices have ranged from $8,000 to $30,000.

The most recent sale price was $26,000 per TDR in first quarter 2008

Development rights are most often bought and sold through private party transactions; under limited circumstances they may be purchased from the King County TDR Bank.
