All buildings – especially those of a “renovatable” age should have a comprehensive renovations by-law which states, among other things, that there has to be a written agreement on hours of work, noisy work, delivery of materials and disposal of rubbish.
Builders will do whatever it takes to save money. The unit owner will go a long with this. That’s why ECs and Owners Corps have to think about these things and act on them before their blocks are turned into building sites.
