Currently trying to get final on a project i ve been working on had an inspector out today and would pass me because hes says i need disconnects on the units i ran other units power is this true.

What i have is a 8 unit property all free standing single family dwellings seperate adresses 1 owner. Currently have dwp approval to mount 2 seperate meter sections one on each side of property. Out of those meter sections i ran all sub feeds under units in crawl space and trenched in between using lbs flex and pvc. On units i used just as passage he wants the lbs removed and disconnects installed to kill power passing under units. Never heard of this before. Any help would be greatly appreciated seeing im done with the job.

That's a really strange setup. Normally I would do separate UG services to each dwelling since they aren't attached.

Assuming the 2020 code, it requires a disconnect outside each unit. If you are using the crawl space to run your feeders to other units I have to agree that a disconnect is required on the side of each unit for it as well as for what runs through it.

If you're on 2020 , as stated, yes you need a disconnect.
If you're not on 2020, perhaps he has his own interpretation of readily accessible location 230-70(A)1

If I’m following this correctly, you have a freestanding meter stack with mains, going to 8 separate buildings? You will need a main in each building as they are a separate structure. As others have said, if it is on the 2020 code, you will need a disconnect outside each building. If not, a main in each panel will be sufficient, unless local code requires it outside.

If you ran conductors in the crawl space under a unit I would side with the inspector in requiring a disconnect with overcurrent protection.

All sub feeds are ran individually. Trenched in between units and ran underneath. Permits were pulled in 2019.

It is a meter gang mounted to one of the structures all sub panels do have main breakers and permit was pulled in 2019. Other units sub feeds do pass under multiple units to get to that specifice unit. Ive done this same set up before to save from a huge amount of concrete work and had no problems so im not sure how to proceed

Is this a new build or existing?

Without knowing that and seeing the actual layout of the site I can't comment on the best way to run the feeders.

It also appears that you in California have your own Code (2019) and I have no idea what it says on this subject. I suggest that you get the AHJ to quote the Article and section he's talking about.

California is on the 2017 Code, but Los Angeles has their own codes as well, don't know if that is a factor though.

I interpret his issue being that because the conductors are going THROUGH another unit in the crawl space, then if a fire fighter came and killed the power to that unit, there are still going to be live conductors inside. Had you TRENCHED under the other units or run it in rigid conduit, he may have allowed it.
