The only thing I can think of that might be useful here would be a general bylaw that specified what people should do when renovating. Perhaps, off the top of my head, that the EC be notified when renovations are planned, something about tradespeople with access to the common property, reasonable limits on disturbance to other residents and some sort of statement to be given about any potential impact on common property-say plumbing connections or whatever. I can think the OC might have an interest in various ways in renovations but they would all be about the conduct at the time and general to any renovations rather than specific to each one requiring a new by-law.
