Question: What is required for me to replace the balcony light with a ceiling fan/light?
Answer: This sounds like a renovation that will require approval.
Without knowing the details of your building this sounds like a renovation that may impact the common property to some extent or require approval via your by-laws.
In that case you can make an improvement application to the Committee of your site. They can approve applications of this nature up to $3000. If you ask your body corporate manager they may have a relevant form you can use to do this.
Because it is a balcony fan there may be some consideration to the appearance of the lot. More probably the committee will need to see that you are engaging a licensed contractor and that the work can be done safely.
