Add SINK in laundry room- HELP!

[mad05cmad05c]

Hello! I am Building a home but builder will not rough-in my laundry room sink pipes. So I must wait until the home is finished (remove drywall) in order to add pipes. Any ideas on how I can add a laundry room sink?

http://media.iccsafe.org/news/icc-enews/2018v15n13/2018SC-IPC802.pdf describes a possibility for getting your drain line for the new laundry sink. As I read it, the 2018 change was to allow it in apartments, and this was available for houses in earlier versions.

Any chance the builder could put a santee into the standpipe, and call it a cleanout with a screw-on cap?
