- Developers may use TDR to achieve extra floor area above the base floor area ratio (FAR) in certain Downtown and South Downtown zones and in South Lake Union IC zones in the area shown on Exhibit 23.50.051.A.
- TDR helps Seattle maintain a variable scale of buildings by allowing density to be moved from one site to another.
- Lots where low-income housing is preserved are eligible “housing TDR sites.” In DMC zones with a maximum FAR of 7 or greater, newly constructed housing may also be eligible as a “DMC housing TDR site.”
- Other eligible TDR sites, in certain areas and zones, include those with landmark buildings, contributing structures under SMC 23.66.032, major open space or arts facilities.
- Purchasers (developers) and sellers (owners of certified TDR) can negotiate sales directly. Or the City can purchase TDR and hold it in its “TDR Bank” for later resale.
- All transactions, whether private or through the City, require execution and recording of a TDR Agreement between the owner of the TDR site and the City.
- The TDR Agreement includes covenants that will run with the land (in the case of housing TDR and landmark housing TDR, 50 years of affordable housing primarily affordable to households with incomes up to 50% of median).
- TDR are validly transferred by Statutory Warranty Deed and are recognized by the courts as real property.
