Effective January 1, 2011 the California Building Standards Commission released mandatory California Green Building Standard Code (CAL Green Building Code).
For the past couple of years cities have been creating their own version of green building codes. The purpose of CAL Green Building Code is to establish a standarization of green building codes and practice throughout municipalicies across California thus provide less design headaches, less construction mix ups, and faster approvals. The new code is applied to new construction both residential and commercial buildings, except certain residential residential buildings.

As a Realtor in the San Gabriel Valley area, I'm thrilled that this has finally come into law so that building and design industry can build homes that are more energy efficient, use less waste, and more water efficient. For years it has been a voluntary practice but now it is mandatory. I have two types of clients who react to this change. One is fearful, a builder that I know. He knew the code was coming so he quickly pulled the permit before the deadline. He was fearful that it would be more costly for redo and redraw everything that he had. He thinks green materials would be more costly and most of his subs don't understand. Another client of mine was hopeful, he was very optomistic about the new code. Because he was building with the same standards 3 years before. He went to green building classes, attended seminars on how to improve his skills of building a better home. New constructions is almost non-exsistent in this market, but because of this new code it's setting the standard, I feel that I now have hope for greener homes. There's still many toxic mortgages and inventories of homes in the market. The real estate market is still going through a cleansing before it can grow. I'm excited that new homes this year and forward will be greener homes!
