OPINION OF THE COURT
The order of the Appellate Division should be reversed, with costs, and the petition dismissed.
In 1987, petitioner, his parents and brother moved into a two-bedroom Mitchell-Lama apartment in Manhattan. 1 Because petitioner was 14 years old at the time, he was the only member of his family not listed as a tenant of record. Petitioner left the apartment for college at some point in the early 1990s and there *778 is no record of his return to the apartment until 1999, when his name first appeared on the apartment’s annual income report. By February 2000, the tenants of record had vacated the apartment, leaving petitioner as the sole occupant. Because he did not reside in the apartment for two consecutive years prior to 2000, the year the last tenants of record (his parents) vacated, petitioner did not qualify for successor rights to the apartment under the Mitchell-Lama Law, but nevertheless remained.
Respondent East Midtown Plaza Housing Company, Inc., a limited-profit housing company incorporated under the Mitchell-Lama Law, owns and operates the apartment subject to the regulations and supervisory authority of respondent Department of Housing Preservation and Development (HPD). Although petitioner was no longer authorized to reside in the apartment, East Midtown apparently acquiesced in petitioner’s occupancy. 2 Following two successful lawsuits by petitioner against East Midtown in 2001 and 2004, East Midtown initiated eviction proceedings against petitioner in December 2004. Petitioner attempted unsuccessfully to submit an application for successor rights and in July 2005, HPD affirmed the eviction because petitioner could not establish that he qualified for such rights.
In September 2005, East Midtown initiated a holdover proceeding against petitioner in Civil Court. In response, petitioner commenced this CPLR article 78 proceeding seeking to annul HPD’s eviction determination. Supreme Court annulled the determination, holding, among other things, that because of East Midtown’s apparent consent to the tenancy, HPD and East Midtown were estopped from evicting petitioner. The Appellate Division affirmed, and we now reverse.
The Mitchell-Lama Law prescribes strict guidelines for tenant eligibility and succession, to which East Midtown must adhere (see 28 RCNY § 3-02 [p] [8] [ii]). HPD is the supervising governmental agency responsible for administering the Mitchell-Lama program in New York City (see Private Housing Finance Law § 2 [15]; New York City Charter § 1802 [6] [d]). Thus, HPD is statutorily required to enforce the Mitchell-Lama Law and regulations regardless of any actions or acquiescence by East Midtown and the other limited-profit housing companies it supervises.

It is well settled that “estoppel cannot be invoked against a governmental agency to prevent it from discharging its statutory duties”

Notes
. The Mitchell-Lama Law (Private Housing Finance Law article II) was enacted in 1955 to offer private housing companies the incentive to develop low- and moderate-income housing (see

. There is no evidence in the record that HPD knew of petitioner’s purported “tenancy” during the time period in question.
