A 137-space mobile home park in Derby, NY. County records put it on 83.2 acres, built in 1960.
With 137 spaces and none reported vacant, turnover here looks slow rather than fast. Grocery, pharmacy, and clinic access here is middling — not next door, not a long haul, 2–9 miles. Zone X on FEMA's map keeps this park outside the special flood hazard area, for whatever that's worth against a map that gets redrawn.

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: New York requires water and utility charges in a manufactured home park to be reasonably related to the actual cost of service, not a profit center (RPL §233(g)). Check the math free with the water submeter calculator.
- 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 Triton Valley Estates-Derby?
Triton Valley Estates-Derby 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 Erie County is $1,343/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 Triton Valley Estates-Derby?
New York requires at least 90 days' written notice before a lot-rent increase, and any increase above 3% can be challenged in court as unjustified — with a 6% ceiling absent court-approved hardship relief (Real Property Law §§233(g), 233-b).

Park value estimate
The New York State assessment roll puts this park at $6.5M — about $48,000 per space. The median across 23 other assessed parks in the county is $30,000 per space, so this one sits in the top quarter of the county.
These are county assessments for tax purposes, not a market appraisal and not an asking price. A park's real value turns on its rent roll, its expenses and its utilities — none of which are in a public record.
