Basement built thread. Getting city permit with my awesome drawing :-)

I know you cannot use a single P-trap, except for a kitchen double sink. If you have 2 bathroom sinks, they would each have thier own trap.

As for your vent, there is usually 1 or maybe 2 common vents in a house. All fixtures have to be vented properly. If you are adding something that is not close to the common vent get a licenced plumber to do it.

The AB code does require the permit for plumbing to be pulled by a licenced plumber. Electrcial you can pull & do yourself.
