Monument Realty is a privately held, Washington, D.C.–based real estate developer and operator founded in 1998 by Michael J. Darby. Over more than two decades, the firm has focused on urban infill and transit-oriented projects across the District and the broader D.C.–Maryland–Virginia (DMV) region. Its integrated platform spans site acquisition, entitlements, development, leasing, and selective investment sales, with activity concentrated in multifamily, mixed-use retail, office, hotel, and, more recently, life science. Notable developments and holdings have clustered around high-growth D.C. submarkets such as Capitol Riverfront/Navy Yard, NoMa/Union Market, and the CBD, as well as close-in suburbs including Bethesda and Gaithersburg, Maryland, and Ashburn, Virginia.
