History

1960s-1970s: Federal Historic Preservation Framework

The National Historic Preservation Act of 1966 established the federal framework for historic preservation that influenced the development of local preservation programs including the eventual creation of the District of Columbia Historic Preservation Office. Early preservation efforts in DC focused on major landmarks and federal properties, with limited attention to neighborhood-scale historic resources and community-driven preservation initiatives. The Georgetown Historic District designation in 1967 demonstrated the potential for local historic preservation while highlighting the need for more comprehensive preservation planning and administration.

1978: DC Historic Preservation Act

The District of Columbia Historic Preservation Act was enacted in 1978, establishing the legal framework for local historic preservation including creation of the Historic Preservation Review Board and designation of historic landmarks and districts. This landmark legislation provided the District with comprehensive preservation authority including design review powers, landmark designation procedures, and enforcement mechanisms for protecting historic properties. The Act balanced preservation goals with property owner rights and development needs through a structured review process and clear designation criteria.

1980s-1990s: Program Development and Implementation

The Historic Preservation Office was formally established within the DC government structure with professional staff including historians, architectural historians, and preservation planners responsible for implementing the preservation program. Early years focused on surveying historic resources, establishing designation criteria, and developing review procedures for proposed alterations to historic properties. The office began building relationships with community organizations, property owners, and development professionals to promote preservation-friendly development practices.
