I just saw this book: http://www.wiley.com/WileyCDA/WileyTitl ... d-buy.html
If you look at the sample it seems like it's really great for California because the author clearly shows any differences from 2010 ADA and 2016 CBC. I'm planning to order this one soon. I just wish the sample pages showed more. I'm hoping there are more diagrams.
This looks like it could be a great study aid for the CASP exam or anyone wanting to improve their knowledge of ADA.
