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.

How much is lot rent at Shamrock Senior MH Community?
Shamrock Senior MH Community 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 Shamrock Senior MH Community?
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, Windsor has its own mobilehome space-rent stabilization ordinance, whose stated limit is "100% CPI, 6% Cap". The city's ordinance text is the authority — confirm the current figure with them.
Where does the water at Shamrock Senior MH Community come from?
Shamrock Senior MH Community operates its own public water system, registered with the EPA as CA4900723 ("SHAMROCK MOBILE HOME PARK"). 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.
