What would your question be?

Based on utility are costs benefiting differently to users: i.e.; owners living on the 5th floor need the lift more than those living on the second floor. They will contribute more to the lift. Other costs like paying someone to put the bins out on the sidewalk are shared based on millièmes.
All this should be clearly itemized in the réglement de copropriété which must have been handed to you when you signed the deeds of purchase.

Unless specified differently in the règlement de copropriété, these type of costs would more likely be shared by tantième (or millième) as one suppose access to these equipments is open to all co-owners or residents (even if some of them choose not to use them).

The law does permit it only if there is a unanimous vote of all co-owners (not only those present or represented at the general assembly) in favor of changing the "règlement de copropriété". It is seldom done because: 1) it is a rather expensive procedure for the copropriété as it involves quite hefty notaire and surveyor fees. 2) it is often next to impossible to obtain the required unanimity on such matters 3) because material restraints - like specific locks - need be installed to ensure that only authorized (read paying) co-owners would be able to use or benefit directly or indirectly from these facilities - which often proves technically difficult, or against safety regulations, or simply annoying for all other users...
