unique building id

i have a building layer that needs periodic updating.  i want to create a unique, unchanging building id for each building.  i thought i would create a field "BLDG-ID" and field calculate the object id + 1.  once i have done that on my initial building layer snapshot, is there a method/idea/script to automatically assign a bldg id based on the highest number within "BLDG-ID" +1, when i digitize a new building?  reason i ask is because object id's can change depending on how the layer gets moved around from database to database.  thoughts?
