Is there a console command to rename a building or other marked area? I am going to customize a house using console and put it back onto the xbox (change ownership, add objects, ect.), so I can't use mods.
As far as I can tell, no, none of the place names in the game can be modified (except by changing the locale, which is different). The console commands that affect location are:
SetLocationCleared <id> 1
cow <worldspace> <cell x, cell y>
(The latter two stand for Center on Cell/World.)
None of those provide much control over the properties of a location, just toggling some flags or placing the character.
