Wetlands & Conservation

Strict Zoning Overlays
highGreenwich zoning includes FAR limits, impervious surface caps, and setback requirements that often exceed state minimums. Variance applications require ZBA hearings.
90-Day Demolition Delay
moderateStructures over 50 years old are subject to demolition delay, allowing the Historic District Commission time to document or seek preservation alternatives.
