(a) When Allowed. The maximum permitted Gross Floor Area for any building or development on a lot may be increased by transfer to such lot of basic Gross Floor Area that is permitted in the Zoning Control Table for the district in which the lot is located but unbuilt upon an adjacent lot that is occupied by an historical, architectural or aesthetic landmark that has been so designated by the Board of Supervisors pursuant to Article 10 of this Code. For the purposes of this Section, an "adjacent lot" is one that either abuts for a distance not less than 25 feet along a side or rear lot line of the lot to which the basic gross floor area transfer is made (hereinafter referred to as the "transferee lot"), or would so abut for such a distance if not separated solely by a street or an alley.
(b) Amount of TDR Available for Transfer. The maximum TDR available for transfer from a Transfer Lot consists of the difference between (1) the allowable gross floor area permitted on the Transfer Lot by Section 124 and (2) the gross floor area of the development located on the Transfer Lot.
(c) Eligibility of Development Lots and Limitation on Use of TDR on Development Lots. TDR may be used to increase the allowable Gross Floor Area of a development on a Development Lot if the following requirements and restrictions are satisfied:
(1) Transfer of Development Rights shall be limited to the following:
(A) The Transfer Lot and the Development Lot are located in a C-3 Zoning District; or
(B) the Transfer Lot contains a Significant building and is located in the South of Market Extended Preservation District, as set forth in Section 819, and the Development Lot is located in a C-3 District; or
(C) the Transfer Lot is in a P District adjacent to a C-3 District and meets the requirements established in subsection (a)(4) above and the Development Lot is located in a C-3 District; or
(D) the Transfer Lot is located in any C-3 District and contains an individual landmark designated pursuant to Article 10 and the Development Lot is located in any C-3 District.
(2) TDR may not be transferred for use on any lot on which is or has been located a Significant or Contributory building; provided that this restriction shall not apply if the designation of a building is changed to Unrated; nor shall it apply if the Historic Preservation Commission finds that the additional space resulting from the transfer of TDR is essential to make economically feasible the reinforcement of a Significant or Contributory building to meet the standards for seismic loads and forces of the Building Code, in which case TDR may be transferred for that purpose subject to the limitations of this Section and Article 11, including Section 1111.6. Any alteration shall be governed by the requirements of Sections 1111 to 1111.6.
(3) Notwithstanding any other provision of this Section, development on a Development Lot is limited by the provisions of this Code, other than those on floor area ratio, governing the approval of projects, including the requirements relating to height, bulk, setback, sunlight access, and separation between towers, and any limitations imposed pursuant to Section 309 review applicable to the Development Lot. The total allowable gross floor area of a development on a Development Lot may not exceed the limitation imposed by Section 123(c).
(d) Limitations. No transfer of permitted gross floor area shall serve to increase the total gross floor area permitted under this Code on the adjacent lot and the transferee lot taken together, either presently or prospectively. No building permit application shall be approved by the Planning Department at any time, nor shall any building permit be issued by any City department at any time, if the result of such approval or issuance would be to increase the total permitted Gross Floor Area of both such lots taken together above such total as calculated on the basis of the floor area ratio limits prevailing at that time for such lots.
(e) Completed Transfers. Any transfer of permitted Gross Floor Area completed prior to the effective date of this Section shall be effective notwithstanding the location of the transferee lot outside the C-3-O District and notwithstanding the aggregate transfer of more than ½ the gross floor area permitted on the adjacent lot under the basic floor area ratio limit, provided all other conditions of this Section have been met.
(f) Restrictions on Transfer. Any restrictions or limitations imposed upon any lot by virtue of the transfer of Gross Floor Area permitted by this Section shall remain in effect notwithstanding an amendment of this Section which removes authorization for such a transfer.
