In order for a building to qualify for area factor increase based on its location, it must touch or have access to which of the following?

For a building to qualify for an area factor increase based on its location, it must touch or have access to a public way. A public way is defined as any street, road, or path that the general public has the right to use, including sidewalks. This access is crucial as it ensures that the building is integrated into the community and facilitates movement and access for occupants and visitors.

Having a building adjacent to a public way indicates that it is situated within a well-connected area, which can enhance its value and utility. The specific criteria for area factor increases often focus on ensuring buildings benefit from the accessibility that public ways provide, thus promoting development in accessible areas.

While options such as a public park or any roadway may seem relevant, only access to a public way directly ties into the regulations regarding area factor increases, making it the correct answer in this context.
