bcr83 – before Jimmy responds, I’ll just make two observations:
1) If your proposed renovations involve changes to the Common Property, then a special resolution would need to pass in order for the Owners Corporation (O/C) to grant consent, but a Special By-Law is only required if the O/C then desires to transfer its obligations to maintain those renovated sections of its common property (floor) to you as the “renovator”, and thereby to all subsequent owners of your Lot; and you agree in writing to that. As I recently mentioned in another post, the rationale for that is that an owner, or more correctly their contractor, may be replacing developer-quality floor tiles (or carpet) with a high-quality / high cost / high maintenance flooring product with acoustic insulation for which the O/C may not want to be responsible.
3) Rather than an O/C having multiple Special By-Laws covering multiple owners’ maintenance responsibilities for changed areas of its Common Property, one generic Special By-Law can cover a multitude of renovation types by any Owner, in which case the Executive Committee or the Strata Manager (if so delegated in their Agency Agreement) can grant consent on behalf of the O/C strictly within the scope and conditions of that Special By-Law; i.e. without the need for a General Meeting.
Over to you Jimmy.
