Bill Summary · HB 6180

Summary — HB 6180 (Stille‑DeRossett‑Hale Single State Construction Code Act amendment)

Purpose

HB 6180 requires newly constructed residential buildings in Michigan to provide a minimum level of electrical capacity at parking spaces to support future electric vehicle (EV) charging. The goal is to ensure new homes and apartment buildings are "EV‑ready," reducing the need for costly retrofits later.

Key provisions

  • Adds section 13h to 1972 PA 230 (MCL 125.1501–125.1531).
  • Effective for new construction on or after January 1, 2025:
    • Single‑family dwellings: each dedicated parking space must have a minimum of 6 kilowatts (kW) of power capacity available for EV charging.
    • Multifamily dwellings: a minimum of 19 kW of power capacity must be available for every 5 parking spaces (i.e., 19 kW per group of 5 spaces).
  • The Michigan Bureau of Construction Codes is authorized to increase or add requirements beyond these minimum standards.

Notes:
- The bill specifies required available power capacity at parking spaces (capacity to support charging) rather than mandating installation of EV chargers or particular equipment models.
- The bureau may adopt stricter or additional rules through the construction code process.

Who is affected

  • Homebuilders and developers of new single‑family and multifamily residential properties in Michigan starting January 1, 2025.
  • Electrical contractors and local permitting authorities (enforcement through the state construction code framework).
  • Prospective homeowners and multifamily tenants (indirectly, via potential changes in construction cost or availability of EV‑ready parking).
  • Utilities and local electrical infrastructure planners may need to account for increased demand at the building level over time.

Implementation & enforcement

  • The requirement is embedded in the state construction code; compliance would be checked through normal building permit and inspection processes.
  • The Bureau of Construction Codes can promulgate additional or more stringent rules (e.g., conduit, panel capacity, wiring, location of outlets).

Legislative status & timeline (selected)

  • Bill electronically reproduced: 11/26/2024
  • Introduced by Rep. Phil Skaggs: 11/26/2024 (formal referral and committee activity continues into 2025)
  • Formally introduced/recorded: January 22, 2025
  • Public hearing: February 6, 2025
  • Joint committee actions and filings in Feb–Mar 2025; reported favorably out of committee and placed on House calendar (House Calendar No. 47, File No. 31) on March 3, 2025.

Potential impacts and considerations

  • Likely reduces future retrofit costs for EV charging by requiring capacity up front.
  • May increase upfront construction and electrical infrastructure costs (service upgrades, larger panels, conduit) for new residential projects.
  • The Bureau’s authority to strengthen rules could broaden obligations (e.g., specifying conduit, outlet types, or additional capacity).
  • Utility coordination and building design (parking layout, electric service sizing) will become more important for compliance and to meet future EV charging demand.
