The provisions of this chapter do not require any changes or improvements to be made to lawfully existing structures. However, when an improvement is made to any existing structure, the provisions of § 82-34 shall apply.

kind to an existing structure to an extent or amount of 50% or more

The above activity shall also address the requirements of 34 Pa.
