BGA's are One Tier Density Level. 

Setup the BGA rules in 'Tools > Options > Terminals > Collapsing BGA'

You define all the settings per Ball Diameter. You can also add additional ball diameters.
  • Ball Diameter
  • Pad Size Reduction (Adj. +/-)
  • Tolerance (Pad Var +)
  • Pad Size Rounding
  • Solder Mask +/-
  • Paste Mask +/-
  • Courtyard Excess +

When I change density levels from "N" to "L" would I expect to see a change in Courtyard excess for BGA devices?

I see in Options\Terminals\SM Grid Array and BGA...that:

"Grid array settings are not subject to Density Level Rules.
