Party Wall

Definition and meaning of Party Wall in real estate.

A party wall is a shared wall built on the property boundary line between two separate buildings, such as row houses, townhomes, or condominiums. It serves as a common structural support and fire barrier for both properties.

Two attached homes sharing a single structural wall on the boundary line between them, with each owner responsible for their own side.
A party wall is a shared structural wall sitting on the boundary; it serves both homes and neither owner may remove it unilaterally.

In more detail

The ownership and maintenance of a party wall are typically governed by local building codes and a written party wall agreement. This agreement specifies that neither owner can alter or demolish their side of the wall if it weakens the structure of the adjoining property.

If repairs are needed, both owners generally share the cost of maintaining the wall. Prospective buyers of townhouses should review these agreements to understand their rights, responsibilities, and how disputes over shared structures are resolved.

Frequently asked questions

Can I make changes to a party wall in my home?

You can typically make cosmetic changes, like painting or hanging shelves, on your side of the wall. However, structural modifications, cutting into the wall, or adding extensions require the consent of the neighboring owner and local permits.

What if my neighbor refuses to pay for necessary party wall repairs?

If a neighbor refuses to cover their share of required maintenance, you can review the party wall agreement for dispute resolution clauses or take legal action in civil court to recover the costs.
