Explanation of the Distribution:

  • Ground Floor: Does not contribute to elevator expenses as it typically does not use it. However, it participates with a very small share of stair expenses.
  • 1st and 2nd Floors: Pay an increasing percentage for the elevator and stairs as they use them more frequently compared to lower floors.
  • 3rd and 4th Floors: These floors pay a higher share because elevator usage is more frequent, and stairs have a greater impact on residents living on higher floors.

The percentages provided are examples and can be adjusted based on the specific rules of the condominium regulations.
