If a development meets the milestones listed by DHCD pursuant to subsection 6404.3(c), the developer shall request a tax abatement certification and provide any outstanding information, documents, or attachments, including a copy of the certificate of occupancy if not previously provided.
Within thirty (30) business days after receiving a complete request for tax abatement certification:
An approved tax abatement shall begin in the tax year immediately following the tax year during which the certificate of occupancy was issued for the final housing unit counted toward satisfying the affordability requirement of the Act and shall continue for a period of thirty (30) tax years; provided that the abatement is not earlier terminated;
Notwithstanding section 6405.3, DHCD may approve a tax abatement to continue for forty (40) tax years after the tax year during which the certificate of occupancy is issued for the final housing unit counted toward satisfying the affordability requirement of the Act if the developer provided in its application information showing a need for a tax abatement of forty (40) tax years for the development and DHCD determines that it is in the interests of the District to award a tax abatement of forty (40) tax years for the development.
