Is it code to tee into existing pipe?

Hi

I am finishing my basement. I wanted to ask if it is ok to tee into an existing pipe on my basement for new bathroom and kitchen like in the drawing?

Existing tees and elbows to first floor are close to bathroom and kitchen.

Red line: new line
Black line: existing pipe

Thanks

Sure, no problem.

But depending on the size of the lines and your water pressure, the usage of the fixtures on the shared lines may cause flow issues between the various fixtures.
