The size of the perimeter a deed controls can be found on the table below. The following are the perimeter options.

;Destroy roads and floorboards : Allows non-citizens to turn roads and floorboards into dirt tiles.
;Build roads and floorboards : Allows non-citizens to [[pave]].
;Build houses : Allows non-citizens to plan and build [[house]]s. Is probably the permission for repairing houses, too.
;Allow allies to do all of the above : Allows [[Settlement#Allies_and_wars|allies]] to perform any of the actions listed above.
