The 2013 California Green Building Standards Code (“CALGreen”) became effective throughout the state on January 1, 2014. CALGreen creates uniform regulations for new residential and non-residential California buildings that are intended to reduce construction waste, make buildings more efficient in the use of materials and energy, and reduce environmental impacts during and after construction.
Residential buildings subject to CALGreen include multi-family residences, and 1-and 2-family dwellings that have 3 or fewer stories. Non-residential buildings subject to the Code include buildings used for retail, office, motels, hotels, and medical services.
The 2013 CAL Green now applies non-residential addition and alteration projects with or without sleeping accommodations and meeting the following criteria:
- The permit application is submitted on or after January 1, 2014
- The floor area for the addition (if any) exceeds 1,000 square feet
- The permit valuation for the alteration (if any) exceeds $200,000
The 2013 CAL Green also applies residential addition and alteration where the addition or alteration increases the building’s conditioned area, volume or size.
