It's rare that the pairs *don't leave the building in a lateral
to the loop. Once you're into the metro, you're usually okay, but
yes, you need to check.

Most buildings only have 1 zero manhole so it's not feasible
to get a second diversified lateral and it doesnt make sense
to lease a second lateral on the same pathway.
