The Lot Rent Index: Oregon

The Oregon state registry lists 1,064 licensed manufactured-dwelling parks across 34 counties, holding 63,194 lots between them. Oregon is one of only three registries in this index that reports vacancies: 2,762 of those lots (4.4%) were reported empty. Of the 882 parks FEMA has mapped, 67 (7.6%) sit in a special flood hazard area. For scale, HUD's FY 2026 fair market rent for a two-bedroom rental across those counties runs $1,008 to $1,922/mo — the area apartment benchmark, not lot rent, which usually runs well below it.

Parks and the county rent benchmark

One row per county. Registered parks and lots come from the Oregon registry itself, as of July 19, 2026. HUD FY 2026 2-BR FMR is what HUD estimates a modest two-bedroom rental costs in that county — the figure Section 8 payment standards are set from. It is the area apartment benchmark and it is not lot rent: lot rent buys the ground under a home the resident owns, and it usually runs well below the FMR. The two are side by side here because the gap between them is the thing worth reporting, not because they are the same measure.

Vacancies are what park operators reported to the state, not an occupancy audit.

What the parks themselves look like

Two federal joins the registry does not carry, matched park by park, and the one occupancy figure a handful of registries do collect. Each says exactly what it counted and what it could not.

• Their own drinking water. At least 152 of 1,064 registered parks (14.3%) run their own EPA-regulated community water system: a well or intake, a distribution main, and a meter on every lot. Those parks are water utilities that also rent land. This one is a floor, not a census: a park counts only where the EPA record matched confidently enough to publish, so the real number is higher, never lower.
• Flood exposure. We hold coordinates for 958 of the 1,064 Oregon parks; FEMA returns a flood zone for 882 of them, and 67 of those (7.6%) sit inside a special flood hazard area. A further 5 fall in FEMA's Zone D, which means the hazard is undetermined because no analysis was done; they are left out of the share rather than counted as not-at-risk. Unlike the water count, this share is not a floor: the parks we could not place or FEMA has not analysed could be more exposed than the mapped ones or less, and we have no basis to say which.
• Vacancy. Operators reported 2,762 of 63,194 lots vacant (4.4%). Oregon is one of only three states here that collects this at all. 1 park reports more vacant lots than it has; that row is left out of the figures above rather than guessed at.

Lot rents we could actually find published in Oregon

One park in the state publishes its current lot rent somewhere we could find and check it. That is a sample of published prices, not a rent survey — 1 of 1,064 registered parks. Nobody should average it, us included. It is here because a real, sourced, dated figure is worth more than a modelled one, and because it shows how little of this is public.

Method, in one paragraph

We pull each state's own licensing or registration file, normalize the addresses, geocode what we can, and join the result to three federal datasets: HUD's county Fair Market Rents, EPA's inventory of active community water systems, and FEMA's National Flood Hazard Layer. Nothing is modelled, estimated, or filled in. Where a source is silent, the page says so and shows nothing. Counts come from the registries and can lag real life: a park that closed last month may still be licensed, and a park that opened may not be listed yet. Every figure above recomputes from the snapshots each time the page is served, so the next pull moves the numbers with no edit to the page.
