For the first time since 1958, Washington, D.C. has taken on new zoning regulations, effective by September 6. According to Washington City Paper, these new regulations came about after nine years and more than 350 meetings.
These new regulations do not totally overhaul the way the District reviewed development proposals. Instead, they revise rules like getting rid of parking requirements for buildings downtown and altering the definition of "fast food" in order to create a more efficient permitting process.
