The Office of Planning has recently proposed the most sweeping changes to the D.C. Zoning Regulations since the 2016 re-write. Proposed amendments include (i) the long-overdue changes to the RA-1 zone; (ii) also long-overdue changes to Alley Lot subdivision and development; (ii) a change in the cumbersome 10-foot rule - to be increased to 16 feet!; and (iv) a 94-page Omnibus Amendment that proposes significant modifications and clarifications to 24 different areas of the Regulations.


Marty Sullivan, a zoning attorney with 25+ years experience in DC zoning, will summarize and explain the proposed changes, and will also provide instruction on how best to participate in the public process to provide the Zoning Commission valuable feedback from the AIA and from individual architects.
