and see what they have to say. Being in CA, you have regional considerations to deal with.
For example, my sister lives in Southern CA. I was out there one summer and while I was there I installed a new hot water heater. I did so with out any trouble. Later she found out that she was in violation because the installer, which was me, did not include four straps around the tank to secure it to a studded wall. An earthquake issue. I did not know. Local issues must be addressed and an outsider does not know them.
