Our grant-funded units are full. Are additional victims who request our grant-funded transitional housing services reported as “Not Served” because we do not have any additional units to provide?

Yes.  These additional victims/survivors are reported as not served in q.20 because they requested grant-funded services that you are unable to provide due to all of your units being occupied.  Report these victims in q.21 as not served due to lack of available housing.  Report the reason “program reached capacity” in q.22.
