Nominating an owner is the first decision
Shared facilities fail through diffuse responsibility rather than through neglect. Each tenant reasonably declines to fund an area used by others, and the enclosure ends up either uncleaned or cleaned by whichever tenant is most bothered by it, which is an unstable arrangement that collapses when that tenant leaves or loses patience.
The stable structure is common property funding with a single contract. The building manager or owners corporation commissions the work, recovers the cost through outgoings and holds the authority to issue rules. That is not a cleaning decision but it determines whether any cleaning arrangement will survive, which is why it belongs at the front of the planning conversation. Recording that decision in the proposal also means a change of building manager does not reopen a question that was already settled.
