Stops any federal agency from carrying out a “covered relocation” until it completes a formal benefit‑cost analysis using OMB’s Circular A‑4 standards, sends an unredacted report of that analysis to its Office of Inspector General (OIG), and publishes a non‑confidential version for the public.

Requires the OIG to review the agency’s analysis and submit a report to specified congressional committees within 90 days of receiving it, including required data, conclusions, and assessments. This adds an independent check and greater transparency before relocations proceed.
