I’m not convinced by the “everybody’s in the same boat” argument. Even though everyone is inconvenienced more or less equally, at the end of the day the lot owners will also own improved common property. The tenants will be exactly where they started.
Everybody isn’t in the same boat. The landlord will pay for the improved common property through OC levies or sinking fund contributions and, true, they will benefit from the improvements to their property. The tenants will however enjoy the common property improvements with no change to rent, at least until the next review. It would be the same as if the landlord chose to install a new air conditioner (a lot improvement) during a tenancy causing a disruption to the property for a day. Agreeing to disagree, I contend that the tenants won’t be exactly where they started, but rather renting a (slightly) better property with no change to rent.
My mild confusion with the original poster was it appeared from the tone that the problem was for someone else (anybody else) to solve. Sometimes stuff just happens and we need to deal with it.
