A 48-space mobile home park in Halcyon, CA. The park runs its own regulated water system, so it — not a city utility — supplies and is accountable for the water at each lot. Everyday shopping is within a couple of miles.
100% of homes in the area report broadband at 100/20 Mbps or faster — one less worry for remote work. Flood risk looks favorable here: the park sits in zone X, clear of FEMA's special hazard designation.
48 spaces — big enough that billing by spreadsheet starts to show its cracks. There's a county-level rent cap on the books in San Luis Obispo County; whether it covers this address depends on incorporation, which the registry alone can't answer.

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.

How much is lot rent at Ken Mar Gardens?

For scale: HUD's FY 2026 fair market rent for a 2-bedroom rental around San Luis Obispo County is $2,512/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 Ken Mar Gardens?
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.
Where does the water at Ken Mar Gardens come from?
