A point has been raised about exclusive use of the balconies or if the balconies may be part of the lot property. A view of the Strata Plan can confirm if the balconies are part of the lot property and a view of the By-laws regarding the exclusive rights of use. If either applies the lot owner that has the exclusive use or owns the balcony they can use it as they like and you and the other occupants would be trespassing if you enter without invitation or good reason to be on the property (eg, putting out a fire).
The car parking issue seems petty, I think you are referring to a motor bike, not a push bike? In short all lots would normally have an allocated car space unless it is an old scheme. Without further info I think you should keep the peace and park in the space now provided.
I have never heard of an OC being able to request or have an Owner or tenant sign a damage waiver, issues of lot Owners being responsible for upkeep etc is normally a term of a specific by-law.
If it is a real concern you may be able to get advice from the OFT however it’s the luck of the draw to whether you will get the right advice, depending on who answers the phone, and they wont give advice in writing. The other option is asking a strata Lawyer.
Hope this helps.
