Do I need a permit for retaining wall construction in Stamford?

Permit may be required

It depends. Whether retaining wall construction needs a permit in Stamford comes down to the details of your project.

Connecticut exempts only retaining walls not higher than 3 feet, measured from finished grade at the bottom to finished grade at the top, that do not support a surcharge; that is stricter than the 4-foot model IRC figure (CSBC R105.2, Building item 3). Walls with more than 4 feet of grade difference need guards where a walking surface, parking area, or driveway on the high side is within 2 feet of the wall (CSBC R404.4.1 as amended). Work in or near inland wetlands or watercourses may also need a permit from the town's inland wetlands agency (CGS 22a-42a). State law requires notice to the Call Before You Dig clearinghouse before excavating or demolishing (CGS 16-349).
