S 3740

Specifies electric vehicle parking space calculation is rounded up if it includes fraction of a whole number and rounded-up parking spaces cannot reduce overall parking supply by more than 10 percent.

2026-2027 Regular Session Introduced by Raj Mukherji and 1 co-sponsor

Clarifies how EV parking credits are calculated, rounded up (without exceeding a 10% total reduction) and integrated early in planning for multifamily and larger parking projects.

Bill Summary · S 3740

Overview

Senate Bill S. 3740 (2026) from New Jersey seeks to clarify and refine how electric vehicle (EV) parking space credits are calculated and applied in the planning process. It addresses rounding rules for fractional EV parking credits, ensures the credits do not erode total parking supply by more than 10%, and specifies when credits are considered in project reviews, particularly for redevelopment or master-plan developments.

Purpose and intent

  • Provide clearer, more predictable rules for EV parking space credits.
  • Ensure rounding of fractional EV parking credit scenarios does not push the total credit beyond the statutory 10% reduction cap.
  • Integrate EV parking credits into early planning stages (concept plan review) to align with redevelopment or master-plan planning processes.

Key provisions and changes

  1. EV parking space calculations and rounding (amends P.L.2021, c.171, C.40:55D-66.20):

    • When EV Make-Ready or EV supply equipment (EVSE) credits produce a fraction of a parking space, round up to the next whole parking space.
    • The rounding up must not cause the total credit to exceed the 10% maximum reduction in required parking spaces.
    • Affected scenarios include:
      • New multifamily developments (five or more units) including condominiums, cooperatives, mutual housing corporations, or mixed-use developments.
      • Parking lots/garages not covered under the multifamily subsection.
    • Credits counting: parking spaces equipped with EVSE or Make-Ready infrastructure installed under prior laws (2020 acts) count toward the current EVSE requirement.

  2. Make-Ready and EVSE requirements by project size (subsections a and b):

    • Multifamily developments must progress Make-Ready spaces and EVSE installations in thirds over six years, with at least one-third of the original Make-Ready spaces installed within three years and another third within six years.
    • Ensures at least 5% of EVSE installations are accessible to people with disabilities during rollout.
    • For parking lots/garages, Make-Ready spaces required scale with the number of off-street parking spaces (ranging from one space for 50 or fewer total spaces to a percentage-based requirement for more than 150 spaces).
    • Provision allowing substitution of Make-Ready spaces with EVSE installations to meet the requirements.

  3. Accessibility and construction code alignment:

    • Standards for accessible Make-Ready spaces and progression to accessible EVSE spaces align with the most recent International Building Code/Residential Code, subject to adjustments by the state Commissioner of Community Affairs.

  4. Exclusions and implementation:

    • Retailers with 25 or fewer off-street spaces and single-family homes are exempt from providing EVSE Make-Ready spaces.
    • The Site Improvement Advisory Board must advise on incorporating these EV requirements into statewide site improvement standards and the State Uniform Construction Code within specified timelines (90 days after enactment).

  5. Application and credits:

    • EV parking credits apply to the concept plan review stage when assessing consistency with redevelopment plans or master plans; credits are not itself a zoning variance.

Affected parties and scope

  • Developers and owners of multifamily residential projects (including condominiums, cooperatives, and mixed-use developments) and parking facilities undergoing site plan review.
  • Local land use boards reviewing site plans for multifamily dwellings and parking facilities.
  • Retailers with limited off-street parking and single-family home developers (exempt).
  • State and local planning/building officials, including the Department of Community Affairs and the State Uniform Construction Code officials.
  • EV charging infrastructure providers and electric utility funding programs collaborating with project developers.

Procedural and timeline aspects

  • Effective date: immediate upon enactment.
  • Multifamily projects: phased implementation over six years (one-third within three years; final third within six years from certificate of occupancy).
  • The advisory board has a 90-day deadline after enactment to propose changes to statewide standards and construction code to reflect these provisions.
  • Credits must be rounded up for fractional calculations, but only to the extent they do not violate the 10% maximum reduction in required parking.

Potential impact

  • Increased predictability in EV parking credits and clearer rounding rules.
  • Encourages earlier integration of EV infrastructure in planning (concept-stage considerations).
  • Gradual expansion of EV readiness in multifamily and larger parking facilities without compromising overall parking supply.
  • Supports accessibility goals by ensuring a portion of EVSE is accessible during rollout.

Note: The bill clarifies interaction with existing EV provisions and ties to prior EV-related statutory frameworks.
