Because:
– it’s a one-off, once the windows are done and paid for, there is no need for anything else to be on the records
– the only element you want binding here is the owners being responsible for payment of the relevant windows
– I have assumed that the OC would continue to be responsible for the windows going forward, as per section 62
– the reason the agreement would bind successors is to provide for any sale/transfer of properties before all the windows are done, and someone saying it doesn’t apply to them apropos payment
– what’s the point of having a by-law, once all the windows are done and paid for? You wouldn’t need it then, would you?
