DC Preservation League

What DC Preservation League does

DC Preservation League (DCPL) is a 501(c)(3) nonprofit organization founded in 1971 in Washington, DC to preserve, protect, and enhance the city's historic buildings, neighborhoods, and cultural landscape. Originally incorporated as "Don't Tear It Down" to save the Old Post Office on Pennsylvania Avenue, the organization adopted its current name in 1984 after the building's grand reopening, broadening scope to a multi-faceted preservation mission. Over its 50+ year history, DCPL has sponsored more than 160 historic landmark nominations and serves Washington DC's eight wards alongside a network of more than 30 residential historic districts.

DCPL's core products are advocacy, education, and digital resource platforms rather than commercial software. Flagship digital products include the DC Historic Sites interactive app and website (covering 800+ individual landmarks and 70+ historic districts), HistoryQuest DC (an ArcGIS-powered map covering approximately 127,000 extant buildings), the Don't Tear It Down Story Map chronicling the organization's founding, and the Legacy Businesses Program mapping 120+ DC businesses operating 20+ years. Educational offerings comprise 30+ programs annually - tours, lectures, panel discussions, and workshops - and the Preservation Initiatives Grant Program channels matching funding to individuals and nonprofits for preservation planning, research, and bricks-and-mortar work. Internal operations are lean: a professional staff of 5 (Executive Director, Director of Development, Community Outreach and Grants Manager) plus 100+ volunteers across committees covering Landmarks, Government Affairs, Project Review, Education, and Development.

Revenue derives from five streams: individual memberships ($65-$500), business memberships ($1,000-$25,000+), tax-deductible donations, federal grants (primarily National Park Service), and the Preservation Initiatives Grant Program. Business goes through a community-led GTM motion centered on volunteer engagement, public testimony before DC regulatory bodies, coalition litigation, and digital outreach. Recent strategic posture has shifted toward high-profile public interest litigation, including federal lawsuits against the Trump administration over East Potomac Park, the Kennedy Center, and the White House Ballroom.
