Is construction with aircrete permitted at all in California?

  • Some older sources (2009, 2012) say that California is the only state where Autoclaved Aerated Concrete (AAC) is not permitted. And since Domegaia's "aircrete" is non-autoclaved I imagine it is even less likely to be permitted. Does anyone have any info on this? or leads to where one should research? Would there be regulation variances between counties? (I'm in Nevada County)

  • In some locations, you can build a "storage shed" as long as its under a certain size and has not been plumbed in when its inspected.

  • So true @HandyDan. Maintaining healthy positive neighbor relations is extremely important for those of us striding to be less dependent on governments. We force government to step in and make everything "legal" when we can't get along as a community.

  • Unless your going to sell the house, I say the only building inspector you have to worry about is your neighbor...

  • It's more like sidestepping the code. Cellular concrete is in the building code and legal. However, when you make your own blocks it's doesn't apply. You could buy a pallet of the real thing and get code approval then use your own product...

  • Just got word back. That was fast! (Thanks KL)

    "Nothing has changed since this article was published, to our understanding. If you build a structure that is less than 120 square feet, it should meet the California code as an acceptable storage space/shed."

    For many people this is an acceptable size. I am building a space that is about 400 sq ft so I need to switch technologies.

  • To Evanflow: I just registered for a workshop in Santa Cruz and realized I should confirm that aircrete is legal in California and in Nevada County, where I also live. If I don't get an answer from the Domegaia folks soon I'm going to check with the county and post their reply here. (If it's not allowed I will need to cancel, and it would be a good idea for Domegaia to update the SC workshop web page to include this important information.)

    To Pronaia: the fire resistance of aircrete is one of the things that attracted me to it as well.

  • My California community suffered great losses in a fire last year. We also would like to know the possibility of rebuilding with Aircrete. Do you know of any approved structures already built in California?
