Who should I look for to protect my rights if the property is not grounded?

There are only two wires in the entrance line?

No grounding wire?

If there is really no grounding wire, it has nothing to do with the property, you should find a developer.

Because developers are building houses, it is their responsibility to leak ground wires.

However, it seems that the grounding wire is missing. I have never heard of it. Please check carefully to see if there is really no grounding wire. If there is really no grounding wire, you can report it to the construction Committee and there will be a reward.
