BSA §72-21 Variance Application (use or bulk hardship)

A §72-21 variance is BSA relief from Zoning Resolution use or bulk requirements when strict compliance creates an unnecessary hardship unique to the applicant's lot. This is the hardship-based path — it is distinct from BSA §73 special permits (which are discretionary approvals of uses the ZR expressly contemplates in that district with special permit conditions). §72-21 is the harder path; §73 permits have higher historic grant rates.

Process steps

1. 1

   Pre-filing site analysis

   30-60d
   Authority: Applicant + zoning attorney

   Site survey, environmental review scoping, title work. Confirm BBL, district overlays, special purpose districts, FAR as-built vs as-of-right.

2. 2

   Community Board presentation

   30-60d
   Authority: Community Board (advisory)

   Applicant presents to the relevant CB zoning committee. CB advisory vote is non-binding but influences BSA's calculus heavily.

3. 3

   BSA application filing

   14-30d
   Authority: BSA (Bulletin Board)

   Form BSA-15 + supporting affidavits. Application fee, 4 hardship findings (financial + physical + uniqueness + minimum variance), environmental review (CEQR if applicable). BSA assigns a case number (format YYYY-XX-BZ).

4. 4

   BSA pre-hearing review + hearing

   90-180d
   Authority: BSA staff + Commissioners

   Staff review for completeness. Public hearing scheduled (calendar typically 3-6 months out).

5. 5

   BSA decision + resolution

   30-60d
   Authority: BSA Board (5 Commissioners)

   Decision: Grant, Grant with modifications, or Deny. Resolution posted with findings. Commissioners vote 5-0 / 4-1 etc.; supermajority not required.

Common pitfalls

• !Self-imposed hardships are NOT grounds for §72-21 relief.
• !Economic hardship alone is insufficient — must show physical uniqueness of the lot.
• !Variance does NOT transfer if the lot is merged or subdivided — new applicant needs a fresh filing.
