Retaining Wall Guides for NYC Owners
NYC Retaining Walls is a licensed and insured retaining wall contractor for all five boroughs, and these retaining wall guides for NYC answer the questions owners actually ask before they call anyone: what a wall costs here, when it needs a DOB permit, what Local Law 37 requires, who pays for a wall on a lot line, and whether a leaning wall is dangerous. Every number is sourced, prices are adjusted to NYC with the RSMeans city index, and code citations point to the rule itself.
