If it is on YOUR deed, without any easement, then it is YOUR property, not common property. Common property is property owned by the community or at least which can be used by any member of the community (e.g. roads, sidewalks). Anything which is owned solely you and which you have the right to generally exclude people from (e.g. your yard, your front walk, your home) is not common property. The terms says it all: common property has common ownership and/or use.
