Actually it is level 50.

Requirements to buy a House

Character with level 50 in 1 of the classes.
Second Lieutenant in 1 of the Grand Companies.

Each character that met the requirements can purchase 1 unowned plot of any size, within any Ward.

So technically Sensu, the level requirement is 50 and there is a long quest chain involved which is your Grand Company quests.

What they should have done was limited the housing to 1 house per SE account per server.
