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.

Is this Sunny Hill's official website or phone number?
No. This is Sunny Hill's page in the Lot Sidekick park directory, built from the state registry. We're independent of the park and can't take messages for it. The park office hasn't added a public contact here yet; if you own the park, claiming the page (free) lets you add one.

How much is lot rent at Sunny Hill?
Sunny Hill doesn't publish its lot rent anywhere we could find, and we won't guess at a figure. Call the park office to ask. If you run this park, you can add your real lot rent to this page for free.
How much can lot rent go up at Sunny Hill?
Illinois sets no statewide cap on lot-rent increases, and state law bars cities from setting a local one (50 ILCS 825) — but every increase needs 90 days' written notice, and a resident whose new rent would top 45% of household income can defer paying the increase for up to a year while listing their home for sale (765 ILCS 745/6, 745/6.4).
