Set by local rules
Do you need a permit for Retaining Wall in Essex County?
In New York, there is no single statewide rule for a Retaining Wall; whether you need a permit is decided locally in Essex County.
Most jurisdictions exempt a retaining wall up to 4 feet tall (measured from the bottom of the footing) with no surcharge, following the IRC baseline; over 4 feet, or any wall holding back a slope, driveway, or structure (a surcharge), needs a building permit and engineered drawings. Many cities lower the threshold to 3 feet, concrete or masonry walls often need a permit at a lower height, and tiered walls count as one combined wall. Because New York leaves this to local jurisdictions, the reliable answer comes from Essex Building Official. Zoning setbacks apply either way.

Code Compliance & Inspections
Because of severe winter weather in New York, any exterior structures or footings must be set below the local frost line to prevent shifting, as mandated by the NYS Uniform Fire Prevention and Building Code.
