Distances are straight-line, so the drive is longer. Internet and neighborhood figures describe the surrounding town — and the rent benchmark, wildfire rank, and tornado count the wider county — not this park’s own lots. The fair market rent is apartment-style rent (HUD’s area benchmark), not this park’s lot rent. Rent limits are not legal advice.

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.
- Thinking about moving here? What to ask a park before you rent a lot, and what lot rent covers and how it goes up.
