re: New Residential Construction Must-Haves/Nice to Haves

Poorly designed sewer cleanouts can cause a lot of grief within a few years.

Make sure you've got cleanouts on outside walls that feed into the bottom sections of any 90-degree turns in your interior sewer lines, outside wall cleanouts near the kitchen sink, laundry and any back bathrooms if possible, and a bi-directional main cleanout (2 caps) near your foundation, between the house and septic or city sewer.
