For residents
- Water billing: if your park bills water by submeter, Oregon caps the usage rate at your utility's rate (ORS 90.572), and your bill should show both meter reads and that rate. Check the math free with the water submeter calculator, or read the Oregon 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.
