Washer drain and sink in basement
That looks nice. It will meet my UPC code requirements
A couple of comments- The lav can drain into the washer vent above the washer trap(wet venting). That will save a connection on your building drain. If you do that, the washer vent will need to be 2".
You don't have your lines sized- Washer drain= 2", Lav drain= 1.5" Current venting layout= 1.5" Again, I'm using UPC standards
What software did you draw with?
