The first thing to understand before planning a condo renovation is the relevant policies of your condo board. Your board may or may not have policies that affect cosmetic decisions or material selections, but most likely it will have policies about what days and times renovations can take place, when materials may be brought into the building, which elevator can be used and so on.
Not checking on these logistical details in advance can cause massive headaches later when trying to schedule deliveries or tradespeople. Your board may require a permit or approval to begin any form of work.
Policies such as these are in place to keep your neighbors happy, so overall they are a positive thing. However, they can slow down a renovation process, so you should give yourself a long timeline. Discuss a projected timeline with a knowledgeable board member and your designer or contractor, and then add at least two months to the timeline so your expectations stay realistic.
