Act of Independent Ownership: Re-register houses

I understand that some owners must re-register their houses at the tapu office this year.
Many English people on an internet forum do not understand who must do it:

Which buildings does this apply to?
Does it include detached (mustakil)houses?
Does it include semi-detached (ikiz)?
Does it include summer houses in kooperatif sitesi?
Which documents must we take to the tapu mudur?
How much does it cost?

I look forward to any information,
Best wishes.
