California Green Building  Requirements for a house, duplex or an ADU



These are some of the most complete in the U.S.

This is  a good thing.


However, homeowners may encounter requirements that seem daunting when starting to plan a new house or ADU.  

We have worked with these requirements for a long time and can help you navigate them so you get the best value.


It is important to keep in  mind that every couple of years,  there are changes to the Code that require increased measures.  For example, on January 1st, 2023,  a requirement for a battery storage system, connected to new solar panels will go into effect.  

Most of the Green Building Requirements will lead to savings in the long term.  They will also help protect your investment by helping to protect your family from future electrical and water failures.


There is a wide range of standards, such as Passive House, that help organize systems for the best performance. We have learned a lot from these standards and keep them in mind from the very beginning, in order to  provide you with a high performance home that ensures the best value for your investment.

If you’d like to know more, please CONTACT US.  We’ll be happy to help.
