For residents
- Water billing: New York requires water and utility charges in a manufactured home park to be reasonably related to the actual cost of service, not a profit center (RPL §233(g)). 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.
