A common area is defined as a real estate asset that is usable by all members of the community, and is owned in common by all owners. At least one sub-definition is limited common area, meaning that the element is useful for some, but not all, owners. It is also owned by all owners and is maintained by the association using funds paid in assessments by all owners.

Examples: atomic number, number of isotopes, atomic weight, density, position in the periodic table, hardness, electrical conductivity, thermal conductivity, color, odor, crystallographic system etc.
Everything depends on the variables involved in the situation. For example:Is the area a common area, or a limited common area reserved for the use of owners, but not all owners?Has the owner been restricted from access to community amenities for cause, such as non-payment of assessments?Who issued the notice of trespass, the association or the local police?Read your governing documents to confirm your right as an owner to be present in the common area. As well, understand the position of the trespass notice issuer.
Typically, in a condominium, the owner owns 'from the paint in' or some other dividing line: studs, wallboard, etc. The association owns everything else. The boundary is defined in your CC&Rs. What you are describing -- a shared stairwell -- sounds like a limited common area that is owned by the association. It is a common area that is available for use by fewer than all owners. The liability may belong to the association. However, if you participated in any way in the stranger's accident, you may indeed, be liable.
Generally, real estate assets in condominium communities are designated as common area, limited common area, or private. Your governing documents give you the boundary definitions for your community and its ownership guidlines. A radiator valve may have its own designation -- partial common element -- which requires a definition within the governing documents. Otherwise, your association attorney can define this term for you.

Your answer is available in your governing documents, where you will find the definition of what is owned in common.
