A single family dwelling unit is a permitted use on any legally created lot or parcel made substandard as to size by the imposition of the initial adoption of the Pitkin County Zoning Resolution of 1955, or the adoption of any relevant amendment thereto subject to compliance with this Land Use Code. Land uses and structures that are accessory to the single family dwelling are permitted. Other uses may be permitted subject to underlying zoning.
(a) "Common ownership" of contiguous substandard size lots or parcels shall cumulate with the exception that:
(b) The aggregate area of the lots or parcels shall be considered as one (1) lot or parcel regardless of diverse times of acquisition by the common owner and whether or not the property was acquired before adoption of this regulation.
(c) If a roadway in public fee ownership that was in place prior to June 2, 1975 provides access to contiguous substandard size lots and separates such lots, the lots shall not cumulate unless the owner has consented.
The Planning Commission may permit the separation of legally platted substandard size lots or parcels that have not been approved by the Board of County Commissioners and that have cumulated pursuant to Sec. 9-20-20, subject to compliance with all of the standards in this section. In the case of multiple, cumulated substandard size lots, the County may limit the number of lots that may be separated and require lot lines to be reconfigured. Where substandard size lots are separated pursuant to this Sec. 9-20-30, and the original substandard would have qualified for a GMQS exemption pursuant to Sec. 6-30 because of the date of their creation, the resulting separated lots shall retain an exemption pursuant to Sec. 6-30 equal to, but not greater than, the exemption that applied to the original lots.
