Green Building Program

Community Development Agency

Green Building is a whole systems approach to construction and building operations that minimizes the large impact that our built environment has on our environment. Green building also provides many benefits to the homeowner including long term value, reduced energy and water use, reduced maintenance, and a more comfortable and healthy indoor environment.

For more information on Marin County's Green Building Program or for green building technical assistance on any building project in Marin, contact Alice Zanmiller, via or email by phone to (415) 473-2797.

Electric Vehicles Requirements & Resources

As of April 12, 2018, builders are required to provide the following levels of electric vehicle (EV) infrastructure. The new requirements are designed to accelerate installation of EV charging stations in order to meet growing demand in Marin County.

Single Family and Two Family Residential Projects

Project Type
Requirement
  • New single family or two family residential
  • Single family or two-family residential, demolition and rebuild
  • Single family or two-family residential additions and remodels that modify the main electrical service panel
  • Comply with CALGreen Measure A4.106.8.1: For one- and two-family dwellings and townhouses with attached private garages, install a dedicated 208/240-volt branch circuit, include an overcurrent protective device rated at 40 amperes minimum per dwelling unit for future EV charging.

Multifamily and Nonresidential Projects

 Project Type
Parking Spaces
Requirements
  • New multifamily developments (greater than two units)
  • Multifamily demolition and rebuild
  • New nonresidential construction
  • Nonresidential demolition and rebuild
 2-10 on-site parking spaces
  • Build 2 parking spaces to be EV Ready
  • Build remaining parking spaces to be EV Capable
 10 or more on-site parking spaces
  • Build 10% of parking spaces to be EV Ready
  • Build remaining parking spaces to be EV Capable
  • Multifamily residential additions and remodels
  • Nonresidential additions and remodels
 Project building or modifying on-site parking spaces
  • If more than 25% of the parking lot surface is modified, add circuit to all parking spaces
  • Where existing electrical service will not be upgraded in the existing project scope, designate capacity for EV Capable parking spaces to the maximum extent that does not require upgrade to existing electrical service
 Projects modifying the electrical service panel
  • If the service panel is modified, add designated electrical electrical capacity for 20% of onsite parking spaces to be EV Capable


Definition & Details

  • EV Capable refers to a parking space with conduit installed and allocated 208/240V 40-amp panel capacity for future EV charging stations.
  • EV Ready refers to a parking space that has allocated 208/240V 40-amp panel capacity, conduit, wiring, receptacle, and over protection devices, with an endpoint near to the parking space.

For projects where requirements for EV Capable spaces exceed 20% of parking spaces, please note that electrical service panelboard(s) shall have sufficient space to install 40-ampere dedicated branch circuit and overcurrent protective device per EV Space up to a minimum of 20% of the total number of EV Spaces. If more than 20% of spaces have EV charging infrastructure installed, a load management software may be used to distribute electrical capacity among those spaces, rather than requiring dedicated electrical capacity for every space.
