Manufactured Home Construction and Safety Standards; Postponing Effective Date

On September 16, 2024, HUD published the "Manufactured Home Construction and Safety Standards" final rule (MHCSS 4th and 5th Sets) in the Federal Register. The MHCSS 4th and 5th Sets final rule established a March 17, 2025, effective date.
