In order to implement the Pitkin County Comprehensive Plan, the development potential from certain lands is sometimes permitted to be transferred to lands elsewhere in the County, under certain conditions. In some circumstances, transferred development rights (TDRs) may be used to create a development right on a parcel that does not have one, and in other cases transferred development rights may be used to expand the size of a house above the base floor area permitted, but within the limits on maximum house size established in Table 5-1. The descriptions of each zone district in this Chapter 3 include information on (a) whether TDRs may be transferred from the district, (b) whether TDRs may be transferred into the district, or within the district, and (c) the purposes for which purchased TDRs may be used in various zone districts. The procedures for transferring development rights are set forth in Chapter 2.
