Summary
Stamford treats retaining walls as a permitted yard obstruction, but any wall over 8 feet must be terraced into stepped sections rather than built as one tall face.
Retaining Walls; Retaining Walls exceeding eight feet (8') in height shall be terraced with at
least three foot (3') wide planted steps between the vertical elements. No vertical element shall exceed a height of eight feet (8').

Full Breakdown
Under the Zoning Regulations' Permitted Obstructions definition, retaining walls are allowed in required yards, but a retaining wall exceeding eight feet in height must be terraced, with planted steps at least three feet wide between vertical sections, and no single vertical element may exceed eight feet. The Regulations separately define a retaining wall as a structure that holds back earth, soil, or water and resists the lateral pressure of the material behind it. Property owners planning a wall taller than 8 feet should design it in stepped tiers from the outset: the Zoning Enforcement Officer reviews Permitted Obstructions for compliance with these Regulations, current through the May 31, 2026 amendments.
Violations & Fines
Building a retaining wall over 8 feet as a single unterraced face, or with vertical steps taller than 8 feet or planted step terraces narrower than 3 feet, is a zoning violation subject to enforcement by the Zoning Enforcement Officer.
