In 2021, Governor Newsom signed into law Senate Bill 9 (SB9) to further address California’s housing shortage. SB9 went into effect January 1, 2022.

SB9 also provides more flexible property setbacks and parking standards and extends subdivision approval expirations for eligible parcels

The Icebox Challenge is a contest and It will be comprised of two small structures (5’x5’ – h: 11’), one built to the Title-24 California Building Code, and the other, built to the PASSIVE HOUSE Standard optimized for the local climate. Each Ice Box contains 500 pounds of ice. The Ice Boxes will be left outside for 7 days (between September 6th & September 13th), and then opened, measuring the amount of ice left in each box. How much ice is left will indicate how well each Ice Box keeps out the summer heat. High-performance buildings are reliable, affordable, comfortable buildings that keep the indoors in and the outdoors out. They stay comfortable and quiet throughout the year, including through summer heat waves, winter storms and power outages.
