New Single-Family Residence in Los Angeles Achieves Official Passive House Institute Certification! Congratulations to the team for successfully completing certification!

This SB-9 project embraces California's forward-thinking regulations to combat the housing shortage in Los Angeles by introducing additional residential units. Designed to meet the rigorous International Passive House Standard, it ensures superior energy efficiency, exceptional comfort, and outstanding indoor air quality.

The International Passive House Standard represents a globally recognized benchmark for energy-efficient building design. It focuses on principles like airtight construction, high-performance insulation, thermal bridge-free design, optimized ventilation with heat recovery, and the use of high-quality windows. These elements combine to create homes that are not only energy-efficient but also provide unparalleled comfort, reduced utility costs, a smaller environmental footprint, and enhanced acoustic performance.

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. This law establishes a streamlined process to develop two primary residential dwelling units on one eligible single-family zoned parcel, and to split one eligible single-family zoned parcel into two separate parcels of approximately equal size. SB9 also provides more flexible property setbacks and parking standards and extends subdivision approval expirations for eligible parcels
