One additional single-family dwelling unit may be allowed on a property designated to the Pitkin County Historic Register, subject to special review approval pursuant to the criteria in Sec. 2-30-30(h)(2) and the following:
(a) One Additional Single-Family Dwelling Unit and Historic Structure(s) Exempt
- The additional single-family dwelling unit may be exempt from GMQS up to the base maximum size permitted by Table 5-1, subject to special review approval pursuant to the criteria in Sec. 2-30-30(h)(2), unless the Board of County Commissioners determines that a smaller dwelling unit size is necessary to avoid visually overwhelming the historic resource(s) on the property, in which case the lower maximum dwelling unit size established by the Board of County Commissioners shall apply. Only one (1) single-family dwelling unit per parcel as it was configured on June 12, 1978, is permitted in addition to the historic structure(s), regardless of the number of historic structures on the parcel and/or the availability of an exemption pursuant to this Sec. 6-30-60. This exemption for an additional single family dwelling unit shall not be available to properties with existing, non-historic single-family dwelling units. The retention of the historic structure(s) is exempt from GMQS and the minimum lot area per dwelling unit requirement of the underlying zone district.
