Is this 2nd floor bathroom drain layout UPC compliant? | Terry Love Plumbing Advice & Remodel DIY & Professional Forum

This site is a goldmine of information. Thanks to all who are participating here. I’ve tried to put what I’ve learned to use in this tub, shower and toilet drain layout for a 2nd floor bathroom remodel. Drawing revisions are painless at this point so I want to get a clear idea of what what will fit where before I start ripping things out. If I’m off track please let me know. I'm also switching out the old ABS for cast iron in hopes of minimizing the sound. Any tips are welcome.
