Rent Increase Laws for Mobile Home and Floating Home Parks in Oregon
Do you live in a manufactured home park or a floating home community? Did you recently get a rent increase notice?
Oregon law offers you some protection against unfair rent increases. Park managers must follow strict rules about how and when they can raise rent. This article explains those rules and what you can do if they aren’t followed.
Rent increase limits
The rules that apply to you depend on the age and size of your park:
Parks at least 15 years old with more than 30 spaces
- Your rent can’t go up more than 6% each year.
- Every five years, your manager can ask tenants to approve a one-time 12% increase for major repairs or upgrades. At least 51% of tenants must agree. See the FAQ section for more details.
Parks at least 15 years old with fewer than 30 spaces
- Your rent can’t go up more than 10% per year (sometimes less, because the limit is tied to inflation. You can see the current limit on this government site).
- Every five years, the manager can propose a 12% increase for major repairs or upgrades. At least 51% of tenants must agree. See the FAQs for more details.
Parks less than 15 years old
- Rent can only be raised once per year.
- There’s no limit on the amount.
Notice rules for rent increases
Your park manager must give you written notice before raising your rent. The notice must:
- Be delivered to you by personal delivery, regular USPS mail, or (if your rental agreement allows) posted on your door and mailed, or emailed and mailed.
- Be dated 90 days before the rent increase goes into effect (or 93 days if only sent by mail).
- Include the new rent amount and the date the increase starts.
If your park manager doesn’t follow the law
If you don’t get correct notice or if your rent is raised too much, you can:
- Talk to your park manager. Share this article to educate them about Oregon's laws.
- Ask them to cancel their notice. Ask your landlord to take back the notice. Have them confirm this in writing (text or email).
- Take legal action: If they don’t fix the problem, you can either:
- Sue for three months’ rent in small claims court.
- Use the illegal increase as a defense if they try to evict you.

Frequently Asked Questions
Every five years, your park owner or manager can propose a rent increase of up to 12% for big improvements. But they can’t raise rent unless 51% of tenants approve.
To raise rent by 12%, the manager must:
- Schedule a meeting to discuss the proposal.
- Send written notice at least 30 days before the meeting explaining the improvements.
- Give at least 14 days’ notice of the meeting date and time.
- Allow each space to cast one written vote.
- Get approval from 51% of park tenants.
Here's how to calculate the rent increase percentage:
- Subtract utilities, garbage, and fees from your current monthly payment to find your actual monthly rent.
- Do the same for the new payment.
- Subtract your old rent from your new rent to find the increase.
- Divide the rent increase by your old rent.
- Multiply by 100 to get the percentage.
Example: A tenant lives in a park with 30+ spaces. It’s 30 years old. Park manager proposes increasing tenants' monthly payment from $1,500 to $1,800. Included in tenants’ monthly payment is $100 for utilities and $50 for garbage.
- Current rent: $1,350 ($1,500 - $100 for utilities - $50 for garbage)
- New rent: $1,650 ($1,800 - $100 for utilities - $50 for garbage)
- Rent increase: $300 ($1650 - $1,350).
- Rent increase percentage: 22% ($300 rent increase ÷ $1,350 old rent × 100).
Since this park has more than 30 spaces and is older than 15 years, the 22% increase is illegal (over the 6% limit).
Only once per year. This applies regardless of the age or size of your park.
