DC Construction Lien Guide

District of Columbia mechanics lien law is governed by D.C. Code §§ 40-301.01 through 40-301.13.
If you provide labor, materials, equipment, or professional services that improve private real property in the District of Columbia and are not paid, DC law allows you to secure payment through a mechanics lien, but only if statutory filing, service, and enforcement rules are strictly followed.
Keep in mind that DC Mechanics Lien, Construction Lien, and Notice of Mechanic’s Lien are commonly used interchangeably to describe the same statutory lien right.
