Better Building

We are committed to better building practices that put our community’s health first while saving energy and money with innovative and thoughtful methods. Buildings are responsible for 30% of the nation’s greenhouse gas emissions, and we are happy to be part of the effort to change that.

Green Building Codes & Standards

  • As part of the adoption of the 2019 California Building Codes (Effective January 1, 2020), the City of Walnut Creek adopted an amendment on 11/19/19 to the CALGreen code that  requires a minimum number of electric vehicle chargers to be installed in the following types of new construction development projects: new multi-family, new commercial, and new hotels and motels. The transportation sector is the City's largest source of greenhouse gas emissions, and a broader network of EV chargers will help residents and visitors transition to driving zero emission vehicles. Read the ordinance here.

  • 2016 California Green Building Standards Code (Effective January 1, 2017) 

  • 2016 Title 24 Energy Code (Effective January 1, 2017)

  • Construction and Debris Recycling Ordinance [PDF]. In order to help meet the state-required 50% reduction in landfill waste, the City of Walnut Creek has initiated a construction and demolition materials recycling program.

  • Water Conserving Plumbing Fixture Requirement. Beginning in January 2014, properties built on or before January 1, 1994, are required by the state to replace noncompliant plumbing fixtures with water-conserving plumbing fixtures when adding, altering, or improving a property.

Resources for Zero Net Energy Buildings (ZNEs)

  • Buildings are major emitters of greenhouse gases and zero net energy (ZNE) buildings are an innovative approach in construction and design that reduces energy use and greenhouse gas emissions. A ZNE building produces as much energy as it consumes through clean, renewable resources over the course of a year. When committing to a high-efficiency building, ZNE offers benefits such as increasing occupants' comfort and potentially higher resale values.

  • Energy Upgrade California is offers resources on zero net energy buildings. California has set goals for new residential construction to be ZNE in 2020 and new commercial construction to be ZNE in 2030.

  • For a general introduction and guidelines to ZNE, check out the following resources:


  • Build It Green is a nonprofit organization whose mission is to promote building green.

  • LEED (Leadership in Energy & Environmental Design) is a green building certification program through the U.S. Green Building Council that recognizes best-in-class building strategies and practices.

  • The Bay Area Regional Energy Network's Codes and Standards program is a joint effort of Bay Area cities and counties to achieve full compliance with the California Energy Code and provides resources on energy and green building codes.
