What are walls constructed along the property line and shared by adjoining buildings called?

The term for walls constructed along the property line and shared by adjoining buildings is known as party walls. These walls are typically used in structures that are built closely together, such as in urban settings where properties are adjacent. A party wall serves as a common dividing structure, providing necessary support for both buildings while also adhering to building codes and regulations regarding property lines and shared structures.

Party walls are important in terms of fire safety and structural stability, as they can also act as fire walls when they are designed to prevent the spread of fire from one building to another. However, their primary characteristic is that they are jointly owned by the property owners of the adjoining buildings. Thus, the legal implications of maintenance and modifications can become relevant in situations involving party walls.

The other terms refer to different types of walls: fire walls are constructed to resist fire spread, load-bearing walls support structural elements above them, and partition walls divide interior spaces but do not bear loads or serve as shared structures.
