For residents
- Water billing: if your park submeters water, California bills it at the utility's rate with combined service and admin fees capped (AB 604) — no markup on the water itself. Check the math free with the water submeter calculator, or read the California water-billing guide.
- Paying rent: ask the park office how they take payment. Parks that run on Lot Sidekick hand residents clear, itemized rent and water bills.
