In the Metro Denver area, lower level finished areas that are 60% above grade in bi-level and split-level homes are treated as above grade GLA. That's what I was taught as a trainee (60% above grade) and it conforms to the MLS practice.
When it comes to county assessors, most treat this space as above grade -- although Arapahoe County does not.
To me, the 60% rule of thumb makes sense -- if a standard 44" high egress window is at grade, then this type of lower level is effectively above grade. This rule applies to split levels, but not ranches and two stories; in those types, it is considered garden level basement.
The most important thing is to be consistent between the subject and comps -- if you treat it as GLA or basement in the subject, do the same in the comps. Either way, a comment as to what the space is and why it was considered one way or another will clarify the issue in the report.
