H.R. 6896 — Federal Facilities Protection and Oversight Act of 2025

This section prohibits demolition or substantial alteration of a public building in the District of Columbia without express congressional authority and requires an approved, finalized construction plan for any demolition site. It defines "public building" as a federally owned or used office or storage facility (including grounds and appurtenances) and "substantial alteration" as any change affecting structural integrity, significantly altering historical character, or exceeding section 3307 thresholds (i.e., $1.5 million total expenditure for construction, alteration, or acquisition; $1.5 million average annual rental; or $750,000 for alterations to leased buildings). This section also amends 40 U.S.C. 8722 (governing National Capital Planning Commission review of federal planning and development in the National Capital Region) by (1) expanding review in subsection (b) to include substantial alterations; (2) requiring consideration of architectural integrity in subsection (d), in addition to location; and (3) adding subsection (f) to define substantial alteration consistent with the above.
