A party wall is a fire resistant wall that separates two connected domiciles. Any changes to the party wall need to fit the fire code. The regulations can be very specific in the area so check the local regulations. It is best to see if there are laws that set out the rules which apply to party walls. In England there is a long legal history so the regulations have been codified. How a notice has to be served to the other party who shares the wall and other things are spelled out.
