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.

Common questions

How many spaces does Sierra Mobile Estates have?

Sierra Mobile Estates has 213 total spaces per the California park registry (as of July 22, 2026).

Is this Sierra Mobile Estates's official website or phone number?

No. This is Sierra Mobile Estates's page in the Lot Sidekick park directory, built from the state registry. We're independent of the park and can't take messages for it. The park office hasn't added a public contact here yet; if you own the park, claiming the page (free) lets you add one.

Where is Sierra Mobile Estates?

17333 Valley Blvd, Fontana, California 92335, in San Bernardino County.

How much is lot rent at Sierra Mobile Estates?

Sierra Mobile Estates doesn't publish its lot rent anywhere we could find, and we won't guess at a figure. Call the park office to ask. 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 Sierra Mobile Estates?

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, Fontana has its own mobilehome space-rent stabilization ordinance, whose stated limit is "100% CPI". The city's ordinance text is the authority — confirm the current figure with them.

Where does the water at Sierra Mobile Estates come from?

Sierra Mobile Estates operates its own public water system, registered with the EPA as CA5510016 ("SIERRA PARK WATER COMPANY INC."). That means the park — not a city utility — supplies and is accountable for the water at each lot. You can look up its monitoring and compliance record by that id in the EPA's Safe Drinking Water Information System.
