GSA’s PBS Office of Leasing is pursuing a sole-source lease extension with the incumbent lessor for continued occupancy of currently leased office space, citing only-one-responsible-source authority and GSAR lease-extension procedures. The planned action is a one-year firm lease extension, with the start date and current lease expiration redacted, intended to avoid a holdover and maintain uninterrupted operations. The agency cites documented organizational, financial, or other uncertainties delaying relocation planning and says moving would create unrecoverable move and replication costs. Market research in Oxford, MS found the proposed rental rates within the local market range and fair and reasonable. GSA states no advertisement is required for lease extensions and no systemic barriers to competition were identified.
