A 14-space mobile home park in Fortuna, CA. It sits in FEMA flood zone AE, a special flood hazard area — worth factoring into insurance and financing. The nearest everyday shopping is a few miles out.
At 14 spaces, this mobilehome park is a fair-sized operation to run water and rent billing across. Humboldt caps mobilehome rent increases in Humboldt County's unincorporated areas — this park may or may not sit inside that boundary, so it's a question for the county.

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 Alton Trailer Park?

For scale: HUD's FY 2026 fair market rent for a 2-bedroom rental around Humboldt County is $1,550/mo — that's apartment-style rent for the area, and lot rent (the ground under a home you own) usually runs well below it.

How much can lot rent go up at Alton Trailer Park?
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.
