1. (1) For housing accommodations which on March 31, 1984 were subject to the City Rent Law, and became vacant after that date, and which are no longer subject to the City Rent Law, and are rented thereafter subject to the RSL, the initial legal regulated rent shall be the rent agreed to by the owner and the tenant and reserved in a lease or provided for in a rental agreement subject to the provisions of this Code, and subject to a tenant's right to a Fair Market Rent Appeal to adjust such rent pursuant to section 2522.3 of this Title.

2. (2) For housing accommodations which on March 31, 1984 were subject to the penalties provided in former section YY51-4.0 of the Administrative Code of the City of New York, and which become vacant thereafter, the initial legal regulated rent for the first rent stabilized tenant shall be the rent established by the DHCR for the prior tenant, increased by the guidelines rate of rent adjustments applicable to the new lease plus such other rent increases as are authorized pursuant to section 2522.4 of this Title, and shall not be subject to a Fair Market Rent Appeal pursuant to section 2522.3 of this Title.

   (b)

3. (1) The initial legal regulated rent for a housing accommodation for which an overcharge complaint or a Fair Market Rent Appeal was filed by a tenant prior to April 1, 1984, and not finally determined prior thereto, shall be the April 1, 1984 rent as subsequently determined by the DHCR. Such determination will be based upon the law or code provision in effect on March 31, 1984.
4. (2) Upon determination of the initial legal regulated rent in paragraph (1) of this subdivision, legal regulated rents subsequent to April 1, 1984 shall be determined in accordance with section 2520.6(e) of this Title.
5. (c) The initial legal regulated rent for a housing accommodation first made subject to the RSL and this Code pursuant to article 7-C of the MDL shall be the rent established by the Loft Board under section 286(4) of the MDL applicable to a lease offered pursuant to MDL section 286(3). Such rent shall not be subject to the proceedings described in section 2522.3 of this Title. Notwithstanding that the rent charged and paid during the first lease term may have been less than such initial legal regulated rent, the owner may request that the next lease rental be the initial legal regulated rent plus the allowable increase established by the Rent Guidelines Board, and such other rent increases as are authorized pursuant to section 2522.4 of this Title.
6. (d) Notwithstanding the provisions of any outstanding lease or other rental agreement, the initial legal regulated rent for a housing accommodation in a multiple dwelling for which a loan is made under the PHFL shall be the initial rent established pursuant to such law. Such rent, whether or not the housing accommodation was previously subject to the RSL, shall not be subject to the proceeding described in section 2522.3 of this Title. Such rent for housing accommodations occupied prior to the granting of the loan made pursuant to the PHFL shall take effect on the date specified in the order establishing the rent. Notwithstanding any other provision of the RSL or this Code, the owner of such housing accommodation shall offer any tenant in occupancy on such effective date or upon initial occupancy a one- or two-year lease at the tenant's option at such rent, which offer shall be made as soon as practicable after such rent is established, whether or not the rent has taken or is then permitted to take effect; and refusal of such tenant to sign such lease, at such rent, and otherwise upon the same terms and conditions as the expiring lease, if any, shall constitute grounds for an action or proceeding to evict and recover possession of the housing accommodation; provided, however, that following the tenant's receipt of the offer of such lease at such rent as lawfully established, a tenant in occupancy on such date shall be allowed 30 days to sign such lease and, if during such 30-day period, such tenant gives the owner written notice of an intention to terminate such tenancy and pays the rent established pursuant to law for such month and for any extended period, the tenant shall not be required to surrender the housing accommodation until 60 days after receipt of such offer. Notwithstanding that the rent charged and paid during the first lease term may have been less than such initial legal regulated rent, the owner may request that the next lease rental be the initial legal regulated rent plus the allowable increase established by the Rent Guidelines Board.
7. (e) Notwithstanding any other provision of this Code, the initial legal regulated rent for a housing accommodation first made subject to the RSL and this Code pursuant to article XIV of the PHFL or section 2429 of article 8 of the Public Authorities Law shall be the rent established pursuant to law which reflects the improvements or rehabilitation and shall be subject to subsequent adjustment by the DHCR. Such rent shall not be subject to the proceedings described in section 2522.3 of this Title. Notwithstanding any other provision of the RSL or this Code: the owner of such housing accommodation shall offer a tenant in occupancy who first became subject to the RSL and this Code on the effective date of such rent a one- or two-year lease at the tenant's option at such rent, which offer shall be made as soon as practicable after such rent is effective; and refusal of such tenant to sign such lease at such rent, and otherwise upon the same terms and conditions as the expiring lease, if any, shall constitute grounds for an action or proceeding to evict and recover possession of the housing accommodation; provided, however, that following tenant's receipt of the offer of such lease at such rent, a tenant in occupancy on such effective date shall be allowed 30 days to sign such lease and, if during such 30-day period, such tenant gives the owner written notice of an intention to terminate such tenancy and pays the rent established pursuant to law while in occupancy, the tenant shall not be required to surrender the housing accommodation until 60 days after receipt of such offer. Notwithstanding that the rent charged and paid during the first lease term may have been less than such initial legal regulated rent, the owner may request that the next lease rental be the initial legal regulated rent plus the allowable increase established by the Rent Guidelines Board.
8. (f) If a housing accommodation is rehabilitated pursuant to either article XIV of the PHFL or section 2429 of article 8 of the Public Authorities Law, and article XV of the PHFL, the provisions in subdivision (d) of this section shall apply, rather than the provisions of subdivision (e), if HPD elects to establish rents for the housing accommodation pursuant to article XV of the PHFL.
9. (g) The initial legal regulated rent for a housing accommodation constructed pursuant to section 421-a of the Real Property Tax Law shall be the initial adjusted monthly rent charged and paid but not higher than the rent approved by HPD pursuant to such section for the housing accommodation or the lawful rent charged and paid on April 1, 1984, whichever is later.
10. (h) The initial legal regulated rent for housing accommodations subject this Code solely as a condition of receiving or continuing to receive benefits pursuant to section 11-243 (formerly J51-2.5) or 11-244 (formerly J51-5.0) of the Administrative Code, as amended, shall be the rent charged the initial rent-stabilized tenant or the lawful rent charged and paid on April 1, 1984, whichever is later, and shall not be subject to a Fair Market Rent Appeal pursuant to section 2522.3 of this Title. However, as to any housing accommodation which previously received tax benefits pursuant to section 11-243 (formerly J51-2.5) or 11-244 (formerly J51-5.0), was not covered by the provisions of the RSL on June 18, 1985, and was made subject to such law by the provisions of chapters 288 and 289 of the Laws of New York for the year 1985 (as amended), the initial legal regulated rent shall be the rent charged and paid on May 30, 1985, or the maximum rent which could have been charged if the housing accommodation had been continuously subject to the RSL for the entire tenancy of the tenant in occupancy on May 30, 1985, whichever is greater.
11. (i) Notwithstanding the provisions of the RSL or any other provision of this Code, the initial legal regulated rent upon completion of the rehabilitation of a Class B multiple dwelling, Class A multiple dwelling used for single-room occupancy purposes, lodging house or a substantially vacant building intended to be used after rehabilitation for single-room occupancy purposes for which a loan is made for such rehabilitation on or after September 1, 1985, under article VIII or VIII-A of the PHFL, shall be the initial rent established by HPD pursuant to such law. Such rent, whether or not the housing accommodation was previously subject to the RSL, shall not be subject to the proceeding described in section 2522.3 of this Title. Such rent shall take effect on the date specified in the order establishing the rent. Notwithstanding the provisions of the RSL or any other provision of this Code, the owner of such housing accommodation shall offer any tenant in occupancy on such effective date a one- or two-year lease, at the tenant's option, at such rent, which offer shall be made as soon as practicable after such rent is established. Refusal of such tenant to sign such lease at such rent, and otherwise upon the same terms and conditions as the expiring lease, if any, shall constitute grounds for an action or proceeding to evict and recover possession of the housing accommodation; provided, however, that following the tenant's receipt of the offer of such lease at such rent as lawfully established, a tenant in occupancy on such date shall be allowed 30 days to sign such lease and, if during such 30-day period, such tenant gives the owner written notice of an intention to terminate such tenancy and pay the rent established pursuant to law for such month and for any extended period, the tenant shall not be required to surrender the housing accommodation until 60 days after receipt of such lease offer. Notwithstanding that the rent charged and paid during the first lease term may have been less than such initial legal regulated rent, the owner may request that the next lease rental be the initial legal regulated rent plus the allowable increase established by the Rent Guidelines Board, and such other rent increases as are authorized pursuant to section 2522.4 of this Title.
12. (j) For housing accommodations whose rentals were previously regulated under the PHFL, or any other State or Federal law, other than the RSL or the City Rent Law, upon the termination of such regulation, the initial legal regulated rent shall be the rent charged to and paid by the tenant in occupancy on the date such regulation ends. For housing accommodations which are vacant on the date the building first becomes subject to the RSL and this Code, such rent shall be the most recent rent approved by the supervising agency, which shall be subject to all increases permitted by law and this Code, and which shall not be subject to a Fair Market Rent Appeal pursuant to section 2522.3 of this Title.

13. (k) Notwithstanding any other provision of this Code, except as provided in paragraph (2) of this subdivision, governmental agencies or public benefit corporations may enter into an agreement with the DHCR, which shall be incorporated into an order of the DHCR, setting forth the conditions under which:

    1. (1) projects receiving assistance or financing from such agencies may register higher and lower initial legal rents for units subject to occupancy and rent restrictions by such agencies, which rents may then be adjusted pursuant to the RSL and this Code, and shall not be subject to the proceedings described in section 2522.3 of this Title; or

    2. (2) projects whose rentals were previously regulated under the PHFL or any other State or Federal law, other than the RSL or the City Rent Law, upon the date when such regulation ends, may register higher and lower initial legal rents for units which have been subject to occupancy and rent restrictions pursuant to such laws, which rents may then be adjusted pursuant to the RSL and this Code, and shall not be subject to the proceedings described in section 2522.3 of this Title. Where the DHCR was the agency regulating rentals pursuant to the PHFL, such terms and conditions shall be incorporated into an order of the DHCR.

       Such agreement or order shall also set forth the conditions under which the higher and lower legal regulated rents may be charged, with due consideration of equities as set forth in section 2522.7 of this Title. No further agreements shall be entered into pursuant to this subdivision on or after January 1, 2000.

       (l)

    3. (1) Notwithstanding any other provisions of this code, the initial legal regulated rent shall be established pursuant to paragraph (2) of this subdivision for housing accommodations located in properties that were or continue to be owned by housing development fund companies (HDFC’s) created pursuant to article XI of the Private Housing Finance Law (whether such an HDFC was for rental housing, a mutual company, or subject to cooperative or condominium ownership or had otherwise previously been subject to this code) where such property has been conveyed pursuant to a judgment of foreclosure or pursuant to a stipulation of settlement in a foreclosure action (whichever occurs first).

    4. (2) The initial legal regulated rent shall be the highest of:

       1. (i) maintenance or carrying charges, common charges, or rent in effect immediately prior to such conveyance;
       2. (ii) any minimum standard rent established by either HPD or DHCR as the respective supervising agency of an HDFC that was in effect immediately prior to such conveyance, even if such minimum standard rents had not been implemented for the specific building or housing accommodation; or
       3. (iii) the rent specifically set by HPD or DHCR as the respective supervising agency of an HDFC where such HDFC or a successor HDFC continues to own the building.
