Oregon Tiny Home Laws: A 2025 Placement Guide

Understanding Oregon's Two Tiny Home Paths: RV vs. House

Oregon has long been a trailblazer for the tiny living movement, a place where misty forests and rugged coastlines inspire a simpler, more intentional way of life. If you're dreaming of parking your own cozy haven here, you're in the right place. But before you pick out your shiplap, it's crucial to understand the legal landscape. The rules for where you can place a tiny home in Oregon are evolving rapidly, and in 2025, they're clearer and more accommodating than ever before—if you know which path to follow.

In the eyes of Oregon law, tiny homes fall into two distinct categories, and this distinction is the key to everything:

1. Tiny Homes on a Foundation: These are legally considered houses or Accessory Dwelling Units (ADUs). They are built on-site, are permanent structures, and must comply with state and local building codes, like the Oregon Residential Specialty Code.
2. Tiny Homes on Wheels (THOWs): These are legally classified as Recreational Vehicles (RVs). They are built on a chassis, have wheels, are registered with the DMV, and must meet RV safety standards (like ANSI or NFPA), not building codes.

This guide focuses exclusively on the second category: Tiny Homes on Wheels (THOWs). Why? Because recent landmark legislation has opened up exciting new opportunities for placing these mobile dwellings on private land, transforming them from weekend campers into legitimate, full-time residences.

The Game-Changer for Rural Living: SB 1013 Explained

For years, the biggest hurdle for THOW owners was the lack of legal long-term parking spots outside of RV parks. That all changed with the passage of Oregon Senate Bill 1013. This groundbreaking law, which came into effect in 2024, authorizes counties to permit a THOW as a legal, rentable dwelling on rural residential properties. It’s the single most important piece of legislation for understanding Oregon tiny home laws in 2025.

What is SB 1013?

At its core, SB 1013 is an enabling act. It doesn't force any county to change its rules, but it gives them the official green light to do so. The law allows property owners in specific rural zones to site one RV (which includes your beautiful THOW) on their land as a long-term residence for a tenant. It’s designed to help ease the rural housing shortage by creating a safe, legal pathway for a new type of housing.

The SB 1013 Checklist: Can You Place a THOW on Your Rural Land?

If a county has "opted-in" to SB 1013, you can likely place a THOW there if you can check all the following boxes:

• Correct Zoning: The property must be zoned for Rural Residential use (e.g., RR-5, RR-10). This is a critical distinction. These rules do not apply to land zoned for farming or forestry.
• Existing Primary Home: The property must already have a primary single-family dwelling on it. You can't place a THOW on a vacant piece of rural residential land.
• One THOW Limit: Only one THOW is permitted per property.
• Utility Connections: The property owner is required to provide approved hookups for water, electricity, and sewage disposal (like a connection to the existing septic system, if capacity allows).
• No Short-Term Rentals: The THOW cannot be used as a vacation rental or Airbnb. It is strictly for long-term residential tenancy.
• Proper Certification: Your tiny home must be legally titled and registered as an RV with the DMV.

Which Counties Have Adopted SB 1013?

As of 2025, several forward-thinking counties have embraced SB 1013, creating legal havens for tiny living. This is where you’ll find some of the best places for tiny homes in Oregon. The most prominent include:

• Deschutes County: A popular choice, Deschutes County requires properties to be at least two acres and mandates a 20-foot defensible space around the THOW for wildfire safety.
• Lane County: Home to Eugene, Lane County has adopted the rule but with one major caveat: RVs under this ordinance are not permitted in mapped floodplains due to conflicting state and federal regulations.
• Clackamas County: This county allows THOWs as "second dwellings" in both rural residential zones and some urban low-density residential zones outside of city limits.

Always check with the specific county's planning department for their exact ordinance, as local interpretations and requirements can vary.

Portland's Unique Rules: Urban Tiny Living Made Easy

While SB 1013 is revolutionizing rural living, the City of Portland has its own set of uniquely permissive rules for urban dwellers. If you’re looking into Portland Oregon tiny house rules, you’ll be pleasantly surprised. Portland's zoning code allows for one "Occupied Recreational Vehicle" on most residential lots that already contain a house.

This isn't a temporary or emergency measure; it's a permanent, legal-by-right allowance. Here’s what you need to know:

• Placement is Key: A towable THOW must generally be parked behind the front line of the main house on a compliant parking pad (which can be gravel or paved).
• Utility Connections are Mandatory: You can't just run an extension cord across the lawn. The city requires a legal electrical connection (like a dedicated 20-amp or larger GFCI outlet) and an approved sewer connection, which can often be made to the main house's sewer cleanout.
• It Remains a Vehicle: The THOW must keep its wheels and maintain its DMV registration. It is explicitly treated as a vehicle, not a building, so you don't need building permits for the home itself—only for the utility hookups.

This progressive policy makes Portland one of the easiest cities in the nation to legally live in a THOW in a backyard setting.

What About Farm Land? A Quick Note on EFU Zones

It's vital to understand that the permissions granted under SB 1013 for Rural Residential land do not apply to land zoned as Exclusive Farm Use (EFU). Oregon law fiercely protects its farmland, and placing any non-farm-related dwelling on it is highly restricted. Living in a THOW on EFU land is only possible if it qualifies as a "farm help dwelling" or "agricultural labor housing," both of which come with strict requirements tied to the farm's income or labor needs. For a detailed breakdown of these complex rules, please read our dedicated guide: Tiny Homes on Oregon Farm Land: EFU Rules.

The 'Medical Hardship' Permit: A Statewide Option

Before SB 1013, the primary way to legally live in a THOW on private land was through a "medical hardship" permit. This option still exists in nearly every county across Oregon and serves as a crucial pathway in areas that haven't yet adopted the newer, more flexible laws.

Here’s how it works:

• Purpose: A medical hardship permit allows for a temporary second dwelling (often an RV or manufactured home) for a person who requires care or who is providing care to a resident of the main home.
• Requirement: You must provide a physician's certification of the medical need.
• It's Temporary: This is not a permanent solution. Permits are typically valid for one or two years and must be renewed. Once the hardship ends, the dwelling must be removed.

While more restrictive, this can be a viable temporary solution for families needing to keep a loved one close.

Next Steps: Finding the Right Spot to Place a THOW in Oregon

Navigating tiny home on wheels Oregon regulations is easier in 2025 than ever before. Your path to legal tiny living depends almost entirely on your desired location and zoning.

To recap, your three main legal pathways are:

1. Rural Residential Land: If you're looking at property in an unincorporated area, check if it's zoned Rural Residential and if the county has adopted SB 1013. This is your best bet for a permanent, legal THOW placement.
2. City of Portland: If urban living is your style, finding a backyard spot in Portland is a straightforward and legal option, provided you follow the city's placement and utility rules.
3. Medical Hardship: In any county, this temporary permit can provide a solution for families with specific caregiving needs.

The golden rule is to always call the local city or county planning department before buying land or making a move. Confirm the zoning and the specific local ordinances. With a little due diligence, you can confidently find the perfect piece of land for your tiny life.
