COVID 19 Update:

In response to COVID-19, City Planning allows project applications that qualify under the Housing Crisis Act of 2019 to submit an optional vesting preliminary application electronically. This shift to accepting forms electronically has shortened the turnaround time, allowing applicants to file remotely without requiring an appointment.

Email with Section I of the Preliminary Zoning Assessment (PZA) form complete with attached architectural plans to initiate the PZA review. Separately, the optional vesting Preliminary Application should be submitted through the Department’s Online Application System.
