PARTY WALL

Party Wall – Shared Structural Wall Defined

In plain language: A party wall is a shared wall found between two separate buildings or within a building, such as between two townhomes or apartments. It might be likened to having a roommate, where the dividing wall of your shared room is your responsibility as well as your roommate's. 

Technical definition: Typically referenced on a policy’s declarations, a party wall, or common wall, is a wall shared between two separate properties. This term is common in party wall agreements in property law, specifically when discussing residential units like condominiums and townhomes. The wall can be located on, or stand at the boundary of, two adjacent lots shared by two separate property owners. 

In the bustling world of real estate, owners of semi-detached houses or duplexes often overlook the concept of party walls. Misinterpretations can often lead to disputes between neighbors regarding responsibility and upkeep.

What Is Party Wall in Insurance?

The foundation of understanding a party wall in insurance lies in its core definition - a shared wall between two properties. The wall can be a dividing wall within a property, like in an apartment complex, or a common wall between two separate buildings. 

These walls are vital in insurance due to liability considerations. Damage to them can have repercussions not only for one party but for all parties sharing the wall. Party walls are a noteworthy aspect that should be mentioned on lease agreements and included in the property management's responsibilities. As such, they're often included in both the property law and the building codes as they can affect fire safety too. 

It's also crucial to understand that a party wall differs from a demising wall (also known as a common wall, dividing wall, or a non-structural wall). While a party wall is shared by two properties, a demising wall separates two spaces within the same property, like rooms in an apartment.
