133AA: Buildings to which this subpart applies
or “This part of the law tells you which buildings have special rules for earthquakes, and which ones don't.”
You could also call this:

“A building that could collapse and hurt people or damage property during a moderate earthquake”

You might be wondering what an earthquake-prone building is. It’s a building or part of a building that could be dangerous during an earthquake. Here’s what you need to know:

A building is considered earthquake-prone if it meets two conditions. First, it would be pushed beyond its limits in a moderate earthquake. Second, if it were to fall down, it could hurt or kill people nearby or damage other property.

The local council, called a territorial authority, decides if a building is earthquake-prone. They look at things like how the building was built, what condition it’s in, and what kind of ground it’s on. If you want to know more about how they make this decision, you can check section 133AK.

Some words used here, like “ultimate capacity” and “moderate earthquake”, have special meanings. These meanings are explained in separate rules called regulations.

Remember, keeping buildings safe from earthquakes is important to protect people and property in New Zealand.
