I'm assuming it's not a qualified improvement since that refers to improvements made inside the building?
The reason that's an incorrect assumption is because the sign is an improvement to "the property" which is not restricted to just being inside or a part of the structure on that property.
Which option would I select to depreciate over 30 years or less if possible?
Bottom line is, since that sign is not something utilized in the production of income on a recurring basis, it's a property improvement. So it gets depreciated over 39 years via GDS. If you're already using ADS on your other "like kind" assets (the building) then it's 31.5 years. For ADS you have to select the option for other asset type in the program and enter it that way in order to get 31.5 years.
But for ADS this won't work at all in the program because in the processing of checking this out in the program for you, ADS is incorrectly giving me 40 years to depreciate when it should be 31.5.
@GabiU flagging you on this.
