Data Center Acoustic Engineering Report Permit Requirement

Current understanding

HB6139 (103rd Legislature) would amend Michigan’s construction code act (1972 PA 230) by adding sec. 10a to require data centers to submit an acoustic engineering report as a prerequisite for obtaining a building permit. The bill is part of a tie-barred data center regulation package (HB6135, HB6137, HB6138, HB6140, HB6141, HB6142) and is currently at the introduced stage. For developers, this would add a new pre-permit engineering deliverable; for local communities, it would create a formal noise-impact record before construction proceeds.

• 2026-06-04 — Businesses: other; moratorium on certain approvals for and operation of any new data centers; provide for. Creates new act. TIE BAR WITH: SB 1019’26: cross-connection with data-center-moratorium: Both bills restrict new data center approvals — one via blanket moratorium, the other via acoustic permitting conditions.

• 2026-06-25 — Public utilities: electric utilities; project labor agreements; require for certain data center contracts. Amends 1939 PA 3 (MCL 460.1 - 460.11) by adding sec. 10kk. TIE BAR WITH: HB 6135’26, HB 6140’26, HB 6137’26, HB 6138’26, HB 6142’26, HB 6139’26: cross-connection with data-center-utility-project-labor-agreements: Companion bills in the HB 6135–6142 data center regulatory package.

• 2026-06-25 — Public employees and officers: other; nondisclosure agreements related to the construction of data centers; prohibit. Creates new act. TIE BAR WITH: HB 6135’26, HB 6141’26, HB 6137’26, HB 6138’26, HB 6142’26, HB 6139’26: cross-connection with public-officer-data-center-nda-prohibition: Both are part of the same coordinated 103rd Legislature package regulating data center development in Michigan — one blocks NDAs by public officials, the other imposes acoustic engineering permit requirements.

• 2026-06-25 — Construction: permits; acoustic engineering report for data center; require to receive building permit. Amends 1972 PA 230 (MCL 125.1501 - 125.1531) by adding sec. 10a. TIE BAR WITH: HB 6135’26, HB 6140’26, HB 6141’26, HB 6137’26, HB 6138’26, HB 6142’26: cross-connection with zoning-data-center-community-benefit: Both are part of the tie-barred 2026 data center regulation package (HB6135–HB6142): the zoning bills subject data centers to community benefit agreements, while HB6139 adds an acoustic engineering report requirement at the building-permit stage.
