Lot rent increase calculator
The most you can raise lot rent in 2026, with Oregon's and Washington's park caps applied to your park's size. Caps reset every year.
The 2026 numbers
| Washington | Oregon (2026) | |
|---|---|---|
| Cap for a mobile-home park | 5% flat | 6% if more than 30 spaces; 9.5% if 30 or fewer |
| Notice before increase | Three months, statutory form | 90 days (ORS 90.600) |
| First-year increase allowed? | No, not in first 12 months | Follows state rules; confirm your park |
Each capped state has its own dated page here, with the statute, the agency that publishes the figure, the history, and the notice deadline for a January 1 increase: Oregon's maximum rent increase for 2027 and Washington's rent increase cap for mobile home lots (HB 1217). Oregon's next figure publishes by September 30, 2026; Washington's park cap is a flat 5% that doesn't move.
California and Florida don't cap space rent statewide, but both require 90 days of written notice — so a full quarter of lead time is the safe habit everywhere.

Common questions
How much can I raise lot rent in Oregon in 2026?
For 2026, Oregon's House Bill 3054 caps mobile-home and marina parks with more than 30 spaces at a flat 6% — a figure written into the statute, not recalculated each year. Parks with 30 or fewer spaces follow the standard statewide cap, 9.5% for 2026, which the state recalculates and publishes by September 30 for the following year. Oregon requires 90 days of written notice either way.
How much can I raise rent in a Washington mobile-home community?
A flat 5% a year under House Bill 1217 (effective May 7, 2025). You cannot raise rent at all during a tenant's first 12 months, you must give three months' written notice, and the notice must carry the statutory language — the Washington Department of Commerce publishes a model form for manufactured-home lots.
Is there a rent cap in California or Florida?
Not statewide for mobile-home lots — but both states require 90 days of written notice before a space-rent increase, some California cities add local rent-stabilization ordinances on top, and Florida requires disclosure and offers mediation when an increase leans on comparable-park rents. No cap does not mean no rules.
What happens if I go over the cap?
The increase can be void or challengeable, and in a capped state a defective notice is worse than a smaller raise. A 6% cap on $525 is $31.50 — the most you can charge is $556.50, and rounding up to $560 puts you over the line. This calculator rounds down for exactly that reason.
