The good news is that most tiny homes are completely legal in most areas of Oregon! From building to zoning code, county and city differences, and small home communities, we’ll explore everything you’ll want to know about tiny living in Oregon so that you can stop dreaming and start doing! 

Are Tiny Houses Legal in Oregon?

Yes! Tiny homes are legal in Oregon!

The state of Oregon has adopted the Oregon Residential Speciality Code (ORSC), which includes a small home specialty code. The Small Home Speciality Code requires that the 2018 International Residential Code (IRC), including but not limited to its Tiny Home Appendix Q, be used for the design and construction of tiny homes. The Small Home Speciality Code defines a smaller home as a single-family residence that is 400 sq ft or smaller. 

Furthermore, the state of Oregon differentiates (and regulates accordingly) between three types of tiny homes. These are permanent tiny homes, temporary tiny homes, and transitional tiny homes. Permanent tiny homes are attached to an approved permanent foundation, temporary tiny homes are built on chassis or frames that can have wheels, and transitional tiny homes are living facilities for people without shelter. Each categorized tiny home has its own regulatory path that tiny home builders, developers, and consumers should be aware of. 

Permanent tiny homes must meet Oregon’s state building code. The Oregon Residential Specialty Code (ORSC) permits one loft per tiny home smaller than 600 sq ft. A ladder is permitted for a loft, and an automatic fire sprinkler system is required. Permits are required for permanent tiny homes. Builders, electricians, and plumbers who work on an ORSC tiny home must be licensed by the state. 

Tiny homes on wheels, such as the Zook Cabin Park Model tiny homes, are classified as temporary dwellings in Oregon, are usually attached to a frame or chassis, and can be mobile. In most areas of Oregon, temporary tiny homes may not be permanently affixed to land for use as a permanent dwelling unless located in a mobile home park. Temporary tiny homes are most frequently regulated by individual counties and cities and not by the state of Oregon. However, tiny homes that are designed for regular movement on public highways are subject to the Federal Motor Vehicle Safety Standards and are limited to a maximum width of 8.5 ft.

Are Park Models the Same Things As Tiny Homes?

In some areas, park models are considered the same as tiny homes, but usually, the distinction between tiny homes and park models depends on the specific area’s regulation definition. So, you might be asking yourself, What is a Park Model Home? 

In general, a park model is a type of tiny home or recreational vehicle that is designed for long-term placement and residential use, usually in a mobile home park or campground. Park models are typically less than 400 sq ft, registered as an RV, mounted on wheels, use a single trailer chassis as their foundation, and have a seal of inspection from the RVIA. In most areas, park model homes are classified as recreational vehicles. Keep in mind that park model homes are not meant to be used for permanent housing. 

On the other hand, a permanent tiny home is usually a home that is 400 square feet or less and is on a permanent foundation. Because of this difference, some municipalities will allow tiny homes but not park models since they are on wheels. Read more about this distinction with our complete article about the differences between park model homes and tiny homes here.

These differences are important to understand because park model-style tiny homes are most frequently regulated as recreational vehicles (RVs) in the state of Oregon, making it difficult to live permanently in a park-model tiny home throughout Oregon. However, tiny houses on a permanent foundation are regulated differently and allow Oregon tiny home enthusiasts a straightforward path toward tiny living!

Frequently Asked Questions About Oregon Tiny House Laws

Can I Put a Tiny House on My Property in Oregon?

Yes. In most, but not all, places in Oregon, you can place a tiny home on your property. If the tiny home is placed on a property that already has a home, then this secondary home is known as an accessory dwelling unit, or ADU. Most, but not all, counties in Oregon allow tiny homes to be used as ADUs. Additionally, only some places, such as Portland, allow tiny homes on wheels for use as secondary residences on a property. Check your local county or city building and zoning code to determine if a small house is allowed on your property in Oregon. 

What is the Small Home Specialty Code in Oregon?

Oregon’s small home specialty code is a set of regulations with the Oregon Residential Specialty Code, which applies specifically to single-family homes that are 400 sq ft or less in size. This code is based on the International Residential Code’s Appendix Q. It requires tiny homes to meet certain regulations, such as having heat detectors, fire sprinklers, and utility connections. Check the code for a complete list of all the rules your Oregon tiny home should follow. 

How Much Does it Cost to Build a Tiny House in Oregon?

Tiny houses in Oregon can cost from under $8,000 to over $100,000 to build, depending on the size and amenities you desire in your tiny home! Of course, you will need land to place your tiny home on as well, and, in most places, you will need to pay for a permit for your home. These and other additions will add to the cost of your tiny home in Oregon.

Where Can I Park My Tiny Home in Oregon?

There are a number of places you can park your tiny home in Oregon. RV parks or tiny house communities are great options for your tiny home, especially if they are RVIA-certified buildings. These locations are usually only intended for short-term rentals. In most places, you can place or park your tiny home on your property and on your property that already has a primary residence on it. There may be other places you can place or park your tiny home, but as regulations differ by county and city, it’s always a good idea to check in with your local laws to determine where you can place your tiny home!

How Much Land Do You Need for a Tiny House in Oregon?

How much land you need for a tiny house in Oregon depends on the type of tiny home you are building, local regulations, and your personal preference. There is no statewide minimum land size requirement to park a tiny house on wheels, but check your local zoning ordinance to confirm that it is true in your county! For a permanent tiny home or a tiny home on a foundation, the minimum lot size will depend on your designated zoning district. Tiny houses, like all residences, must follow setback laws as well as utility requirements and thus must have enough land for all regulations to be followed. 

Does a Tiny Home Add Value to Property?

Yes! Tiny homes do add value to a property! Permanent tiny homes can increase the value of your property. This value depends on the structure’s quality and the land’s potential appreciation. Additionally, tiny houses can generate income when used as vacation rentals, such as Airbnbs. This option might be lucrative in a state like Oregon, known for its stunning natural beauty and thriving tourism industry.
