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.

How much is lot rent at Williams?
Williams doesn't publish its lot rent anywhere we could find, and we won't guess at a figure. Call the park office to ask. For scale: HUD's FY 2026 fair market rent for a 2-bedroom rental around Mendocino County is $1,713/mo — that's apartment-style rent for the area, and lot rent (the ground under a home you own) usually runs well below it. 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 Williams?
California has no statewide cap on space-rent increases, but the Mobilehome Residency Law requires 90 days' written notice (Civil Code §798.30), and many California cities add local rent-stabilization ordinances — check your city before assuming there's no cap. On top of that, Ukiah has its own mobilehome space-rent stabilization ordinance, whose stated limit is "100% CPI, 5% Cap". The city's ordinance text is the authority — confirm the current figure with them.
