Is this a code violation

[jetlag]

Can an outside disconnect box be install below a meter socket and wired onto the same lugs on the meter that the s e conductors to the house are on. The main house does not have an outside disconnect . It was the old 3 wire into the house. Someone came later and wired in the outside box to go to a room added on .

So there's fuses or breakers inside the house?

If so, then you'd have a violation of 225.34 if you added a disconnect outside.

The lugs in the meter socket would also have to be rated for more than one conductor.

230.2 says a building shall only be supplied by one service. one service may supply up to six service disconnects(with some exceptions), but these disconnects must be grouped together according to 230.71.

also the lugs in the meter most likely are not designed for more than one conductor.

Only big problem is the grouping as mentioned. Is no easy fix. Even if you add second disc outside you have promlem cause inside is now sub panel and needs 4 wires

The inside panel is a 150a and has breakers for the main house . It is an old meter socket , does it usally indicate inside the socket if lugs are rated for more than one set of conductors ? I know two things they did wrong and that was they parallelled two #6 cu white conductors for each lug on the 100a box. So it seems the main violation is the disconnect outside is not grouped with the disconnect on the inside panel.

Each Service Disconnect must also be labeled "Suitable for use as Service Equipment". What size are the Service Entrance Conductors? Can they handle the combined calculated load served by both panels?

You could also have 310.15(B)(6) problem with the size of the wires going to the 150A and 100A panels. You're supposed to only use 310.16 for those and not 310.15(B)(6) when there are multiple sets. New SEU cable would also be limited to 60C if you have it. I would hope old SEU would be grandfathered. Sounds like you may have individual conductors though.

Im not trying to fix it I just went on service call because the power was out in the add on room . Thats when I found the power came from the outside disconnect. There is only one 20a breaker in the 100 a disconnect. The neutral wire was loose in the box. I was just wondering what the violation was , I knew there had to be code violations.
