Federal Mass Timber Procurement Preference

Full Title:
Mass Timber Federal Buildings Act of 2026

Summary#

This bill would require the General Services Administration (GSA) and the Department of Defense to give priority in federal building contracts to projects that use innovative wood products (often called mass timber) made and harvested in the United States. The preference applies to construction, alteration, acquisition, and leases of public buildings, including military installations. The bill also orders a short, formal lifecycle study (cradle-to-gate) of new public buildings that use these wood products and a report to Congress.

  • Main change: Federal contracting officers must prioritize using U.S.-made innovative wood products for public buildings, when achievable.
  • Sourcing rules: The wood must come from U.S. manufacturing facilities and U.S. forestlands from “responsible sources.”
  • Priority for certain sources: Extra preference is given to wood from restoration practices, actions that reduce wildfire risk, and from underserved forest owners (including Tribes and small family forests).
  • Documentation: Agencies must seek documentation to verify the source claims.
  • Study and report: The GSA must complete a cradle-to-gate life-cycle assessment (following ISO standards) and report results to Congress and the public within set time limits.

What it means for you#

  • Federal agencies (GSA and DoD):

    • Must give priority to buildings that use U.S.-sourced innovative wood products, where “achievable.”
    • Must seek documentation proving where the wood came from and how it was produced.
    • Must complete and publish a lifecycle assessment and report to Congress.
  • Contractors and builders:

    • Federal contracts for public buildings may favor bidders who plan to use U.S.-made mass timber and who can verify responsible sourcing.
    • Contractors may need to collect and provide sourcing and certification documents.
  • U.S. mass timber manufacturers and forest owners:

    • Could see increased federal demand if they meet the bill’s sourcing and production rules.
    • Particular advantage if their wood comes from restoration projects, wildfire-risk reduction efforts, or if they are designated underserved forest owners.
  • Military installations:

    • Included in the definition of public buildings, so Defense construction projects are covered.
  • Design and project planning:

    • Federal project teams may change materials choices, designs, and procurement plans to meet the preference.

Expenses#

No publicly available information.

  • The bill text does not include a fiscal note or cost estimate.
  • This could mean additional administrative work for agencies to verify sourcing and prepare the lifecycle assessment.
  • This could mean changes in procurement costs or project timelines if U.S. mass timber supply is limited or more expensive than other materials.
  • The lifecycle assessment and reporting will require staff time and possibly outside technical help, but the bill gives no dollar amounts.

Proponents' View#

  • The bill appears intended to increase use of U.S.-made innovative wood products in federal buildings.
  • Supporters may argue this could boost domestic manufacturing and rural economies by favoring U.S. facilities and forest owners.
  • The bill targets wood from restoration practices and wildfire-risk reduction, which could be presented as supporting healthier forests and community protection.
  • The required lifecycle assessment could be used to measure climate-related impacts (global warming potential) of using mass timber in federal buildings.
  • The bill appears designed to give Tribes and small family forest owners better access to federal demand.

Opponents' View#

  • One concern is that the bill gives agencies broad discretion (“to the maximum extent achievable as determined by the Administrator or the Secretary”), which may reduce predictability for bidders and contractors.
  • The bill does not include guidance on how to resolve limited domestic supply. This could cause higher costs or project delays if U.S. mass timber is not readily available.
  • The term “seek appropriate documentation” is open-ended, so enforcement and verification procedures are unclear.
  • The lifecycle assessment is limited to cradle-to-gate (up to the point the product leaves the factory). This leaves out in-use, maintenance, and disposal impacts, so it may not show the full climate effects of using mass timber.
  • No cost estimates, funding, or staff needs are provided, so the real administrative and implementation costs are unknown.
