When you own two or more rating units, they might be treated as one unit for rating purposes. This happens if you own them yourself, or with someone else, and they are used together as a single unit. They also need to be next to each other, or only separated by things like a road or a river.

You will be treated as owning one unit if all these conditions are met. The law says that the rating units must be used jointly and be close to each other. This is how the law decides whether to treat your rating units as one or separate units for rating.
