The problem you will run into with leasing, especially if it's a multi unit spot or the owner has multi properties, you are responsible for maintenance. There for you will prob have a fire inspection unless you are leasing out something like a single unit on someones personal property. Most of the time owners will have them do all the properties at once or they will want to see all of the units at 1 location at the same time if they are out there. I have never lived in cali so I'm not sure on the fire inspectors in that area and how they roll so might not be how it jives there. If there is a bunch of grows around where you are it's a safe bet they are going to show up. Fire marshals, at least where I have been in commercial spots, are pretty savvy at this point. Hell we got called on one for not having glass in the hoods of MH fixtures and checking all the ballasts for UL just to give you an example. IE if they see a bunch of A/C's or minisplits they are coming by.
So now you have to make the decision if you want to get a spot like that and not do something super perm that can be taken down for inspection, and if that is the case all the wiring ect will have to be up to code, or go for the ideal spot which is gonna take some time. Trust me everyone and their dog I know are always looking for spots like that and we scoop them as soon as we find them even if we don't need them at the time. It takes time to find spots like that and usually takes some kind of relationship with the owner through you or a friend if you are looking to lease/rent.
This is something you need local help on to get a good idea cause it could be totally different from state to state and area to area.
