BLM Building Codes and Standards updated 03/15/2025

Federal Law. The Public Buildings Amendments of 1988, 40 U.S.C. 3312 (formerly section 21 of the Public Buildings Act of 1959, 40 U.S.C. 619), require that each building constructed or altered by GSA or any other federal agency shall, to the maximum extent feasible, be in compliance with one of the nationally recognized model building codes and with other applicable nationally recognized codes.

Nationally Recognized Codes. For all design and construction work performed on federal buildings by BLM or those functions under BLM’s construction authority, BLM has adopted the technical requirements of the following nationally recognized codes and standards referred to in this subsection (including any and all accumulative supplements). The technical requirements of these nationally recognized codes and standards will supplement other BLM requirements mandated by Federal Laws and Executive Orders, as well as other BLM criteria noted within this document that has been established to meet our customers’ needs and their unique requirements.

State and Local Codes. BLM recognizes that the national model building codes are typically the foundation of state and local building codes. State and local codes also represent important regional interests and conditions.

Legally, however, buildings built on federal property are exempt from state and local building codes. Local building permits and approvals are not required as BLM is the Authority Having Jurisdiction (AHJ). Notwithstanding, it is BLM’s policy to comply with state and local building codes to the maximum extent practicable. Should a conflict exist between state and local codes and the BLM adopted nationally recognized codes, the BLM requirement shall prevail. All code conflicts shall be brought to the attention of the BLM National Operations CenterBranch of Architecture and Engineering (NOC AE Branch) for resolution.

The BLM National Operations Center - Branch of Architecture and Engineering is charged with providing A/E technical assistance and direction for the BLM. The BLM NOC A/E Branch requires the following nationally recognized codes and standards be incorporated into all BLM projects (where applicable):
