For residents
- Water billing: Illinois bars charging residents again for common-area water the utility already bills separately, and where common-area use isn’t separately metered, caps what residents can be billed at 80% of the total utility bill (765 ILCS 745/6.2). Check the math free with the water submeter calculator.
- Paying rent: ask the park office how they take payment. Parks that run on Lot Sidekick hand residents clear, itemized rent and water bills.
