How to find more details on municipal zoning code?
I have a client who would like to set up a business that stores industrial equipment outdoors (in California). This would be on land that is zoned as industrial and it permits storage, per the municipal zoning laws. But I want to be able to definitively tell my client that he can/can’t store *industrial equipment outdoors*. The code doesn’t go into this much detail and the city officials I’ve communicated with have given their verdict on it but without citing a source.

My client’s purchase of the land depends a lot on what I tell him. I’m wondering where I can find accurate information that can answer his question. Any advice? TIA!
