  • In the event that a Private Dwelling is demolished on or after September 1, 2004, the tax lot upon which such Private Dwelling was located is not eligible for 421-b benefits for a period of three years commencing upon the date of issuance of the demolition and removal permit for such Private Dwelling;

BENEFITS GRANTED
  • Construction period (“preliminary”) benefits: projects that have received a preliminary certificate of eligibility are eligible for a construction period exemption from taxes (other than assessments for local improvements) upon any increase in assessed valuation over the prior assessed valuation for up to two years;
  • Post-construction period (“final”) benefits: projects that have received a final certificate of eligibility are eligible for an eight year tax exemption (two years full exemption plus a six year phase out).

APPLICATION PROCEDURE:

  • Preliminary benefits: in order to receive construction period benefits, a 421-b application must be filed within ninety days of commencement of new construction or reconstruction and prior to the issuance of a temporary or permanent certificate of occupancy; 
  • Final benefits: in order to receive post-construction period benefits, a 421-b application must be filed within ninety days of the issuance of a certificate of occupancy for new construction and within ninety days of completion of construction for reconstruction; 
  • Timely completion of applications: all documentation required to process the application must be submitted to HPD on or before December 31, 2009; 
  • HPD may waive the filing deadline for an application for final benefits if HPD, in its sole discretion, determines that the property owner reasonably relied upon a representation by the seller of the property that the seller would file or had filed a final application, provided that the property owner provides all documentation required to process the application on or before December 31, 2009;
