Oregon & Washington Tiny Home Dealers vs Builders: Which Is Right For You?
Searching for a tiny home pulls up two very different options. On one side you have tiny home dealers selling factory-built park model RVs from large manufacturers like Cavco and Champion. On the other side you have custom tiny home builders, often a two- or three-person shop hand-framing homes one at a time in a driveway or small fab shop.
Both paths can get you into a great home. They come with very different price points, timelines, certifications, and risk profiles. Here's how they actually compare.
First, A Quick Clarification: Tiny Homes Are Not ADUs
This trips up a lot of first-time buyers, so worth stating up front. Tiny homes and park model RVs are built to ANSI A119.5, the federally recognized park model RV standard. They sit on a chassis, title like an RV, and place on RV-zoned lots, rural properties under programs like Oregon SB 1013, or inside park model communities.
ADUs (accessory dwelling units) are a completely different product. They're built to state residential building code, permanently placed on a foundation on a primary-residence lot, and permitted through the local building department as a second dwelling.
This article is about tiny homes and park model RVs. Different rules, different buyers, different decision.
The "Mobile Dwelling Unit" Use Case: Like an ADU, Without the Baggage
A lot of our buyers come to us looking at a park model RV as the practical alternative to building an ADU. Same goal - add livable space to a property for family, rental income, a home office, or a guest suite. The path is just a lot cleaner.
When you use a park model RV this way - think of it as a Mobile Dwelling Unit - you get the usable space an ADU gives you without most of the paperwork, cost, and long-term tax impact that comes with a permanent structure:
- No foundation required. The unit sets on piers or blocks. No pouring concrete, no frost line engineering, no foundation permit.
- No permanent utility connections required. Standard RV hookups handle water, sewer, and electric. No extending municipal service lines, no trenching for a permanent gas line, no second meter.
- No ADU permit process in most counties. Because it titles as an RV, not as real property, you sidestep the building department gauntlet that ADU projects live in for months.
- No property tax increase on the home itself. Most jurisdictions don't add a titled RV to the assessed value of your land the way a completed ADU raises your tax bill every year going forward.
- Placement in days, not months. An ADU build typically runs six to twelve months minimum. A Mobile Dwelling Unit gets delivered and set in a day.
- Movable. Sell the property, change your mind, upgrade later - you can relocate the unit. An ADU stays where you built it.
Rules vary by county, so always check placement requirements for your property. In most of Oregon and Washington, private property placement is far less restricted than most buyers assume. Oregon SB 1013 in particular has opened up residential use on rural properties in a way the ADU path simply cannot match on cost or speed.
Why Big Tiny Home Manufacturers Don't Sell Direct
The large production facilities that build park model RVs - including Cavco, Champion, Skyline, Athens Park - almost never sell direct to the buyer. There's a reason for that, and it works in the buyer's favor more than most people realize.
A production facility runs on output. They're pulling units off the line every day, managing raw material supply chains, engineering new floor plans, and meeting ANSI A119.5 code requirements. Their entire operation exists to build homes fast and at scale. Selling one unit to one customer, fielding financing questions, arranging delivery to a private lot, coordinating setup, and handling a warranty call two years later - none of that is what a production facility is set up to do.
That's what a tiny home dealer is for.
Dealers exist so manufacturers can focus on building and buyers can work with a real human. Your dealer walks you through floor plans, helps you pick finishes, coordinates delivery, handles placement and permitting questions, lines up financing, and services the home after the sale. The manufacturer ships the product. The dealer gets you into it.
Myth: "Buying From a Store Next to the Production Facility Gets Me a Better Deal"
You'll sometimes see tiny home showrooms located next door to a park model RV production facility. Worth knowing what those actually are: independent dealers, same as us. They are not owned or operated by the manufacturer. They buy inventory from the same production line, negotiate the same wholesale pricing, and handle their own sales, financing, and warranty work.
The only advantage they have is physical proximity - they can walk over and pick up a unit. For you, the buyer, that advantage disappears fast. Transport cost to your site is calculated from the production facility to your lot no matter which dealer sells you the home. Warranty service still routes through a dealer tech. Placement in Oregon or Washington is handled by whoever actually knows the local rules.
Don't let proximity to a factory logo fool you. Every dealer in the country sources from the same production line. What separates them is local expertise, in-house service, and inventory on the ground where you live.
What a Tiny Home Dealer Actually Does For You
A good dealer brings four things to the table that buying direct (if you could even do it) would not:
Lot models you can walk through and fast delivery. At NW Tiny Homes, we keep lot models of every style we sell on display at our Portland, Oregon and Snohomish, Washington locations. You can walk through each one, see finishes in person, feel the space, and know exactly what you're buying before you commit. When we have matching inventory on site, delivery can happen the same week. For custom orders, our build-to-delivery window runs 8 to 12 weeks - dramatically faster than a small custom builder because the manufacturer we work with produces dozens of units per month, not one or two.
Local expertise. A dealer who sells in Oregon and Washington knows which counties allow park model RVs as full-time residences, how Oregon SB 1013 is changing the rules for tiny homes on rural land, which placement permits your lot needs, and what utility hookups are required. A production facility two thousand miles away cannot answer any of that.
In-house warranty and service. This is where NW Tiny Homes does it differently than most dealers. At a typical tiny home dealer, warranty work routes back to the manufacturer's service team. That means you wait on their regional tech's schedule, their availability, and their queue of calls from dealers across multiple states. We don't do that. We run our own in-house warranty team - real people, based locally, who know every unit we've sold. When something needs a fix, we handle it directly on our schedule, not the manufacturer's. Faster response, tighter quality control, and accountability that lives under our roof. See how our warranty process works here.
Financing. Dealers have standing relationships with lenders that specialize in park model RVs. Buyers walking into their local credit union cold for a tiny home loan often hit a wall. We do this every week.
Where Custom Tiny Home Builders Still Make Sense
Not every buyer should go the dealer route. Custom tiny home builders have real strengths for the right person.
A small shop building one or two homes a month can build almost anything you ask for. Unusual floor plan, specific reclaimed materials, off-grid solar setup tuned to your exact site, a trailer chassis built for rough terrain, a pet-specific layout - that's their wheelhouse. If your vision is specific and no production floor plan comes close, a custom builder will get you there.
A Note on Certification: ANSI A119.5 vs NOAH
This is where first-time buyers get tripped up. Park model RVs from major manufacturers are certified to ANSI A119.5, the federally recognized national park model RV standard covering structural, electrical, plumbing, and fire safety. It's accepted in all 50 states by RV parks, insurance carriers, lenders, and state and local jurisdictions. Every unit we sell ships with this certification.
Most smaller custom builders don't certify to ANSI A119.5. The more reputable ones certify through NOAH (National Organization of Alternative Housing), a third-party inspection service that inspects tiny homes on wheels at multiple build stages - foundation, framing, electrical, plumbing, and final. A NOAH seal is legitimate and it does help with insurance and financing at some lenders.
That said, NOAH is not ANSI A119.5. It's accepted in fewer jurisdictions, some RV parks and communities only take ANSI A119.5 or RVIA-stamped units, and plenty of small builders carry no certification at all. If you go the custom builder route, ask directly: What certification does this home carry? Who inspected it? Can I see the stamp? Don't guess.
The Trade-Offs
- Lead times of six to twelve months, sometimes longer
- Build prices typically 30 to 60 percent higher than a comparable factory-built unit
- A small-shop warranty that depends on the builder still being in business in five years
- Unpredictable timelines when the builder's one employee gets sick or lumber orders run late
- Less financing flexibility (many lenders won't finance one-off custom or non-ANSI builds)
For buyers who need exactly what a production facility doesn't offer, those trade-offs are worth it. For most buyers, they are not.
Why a Park Model RV from a Dealer Wins for Most Buyers
If you're looking at a tiny home as a primary residence, a vacation property, a rental unit, or a Mobile Dwelling Unit on family land, a park model RV from a dealer is usually the stronger choice. Here's the honest reasoning.
Large production facilities build park model RVs in controlled environments with engineered plans, quality checks at every station, and ANSI A119.5 certification stamped on every unit. The framing is tighter, insulation is consistent, and plumbing and electrical systems pass third-party inspection before the home leaves the line. A small builder in a driveway cannot match that consistency, no matter how skilled.
You also get known numbers on the front end:
- Locked price at signing
- Same-week delivery on in-stock units, 8 to 12 weeks on custom orders
- ANSI A119.5 certification accepted in all 50 states
- Manufacturer warranty backed by a company that has built homes for decades
- In-house warranty team at NW Tiny Homes for faster local service
- Financing programs designed specifically for park model RVs
- Proven floor plans that thousands of owners have lived in and refined
The price gap is not small. A 399-square-foot park model from our lot often lands in the same range a custom builder would charge for a 240-square-foot tiny home on wheels. More space, faster delivery, stronger warranty, nationwide certification, lower risk.
Quick Comparison: Dealer vs Custom Builder
| Tiny Home Dealer (NW Tiny Homes) | Custom Tiny Home Builder | |
|---|---|---|
| Timeline | Same week (in-stock) / 8 to 12 weeks (custom) | 6 to 12+ months |
| Price | Locked, lower per sq ft | 30 to 60% higher |
| Customization | Floor plan and finish options | Nearly unlimited |
| Certification | ANSI A119.5 - federal, all 50 states | NOAH, ANSI A119.5, or uncertified |
| Warranty | In-house warranty team (NW Tiny Homes) | Depends on builder's longevity |
| Financing | Specialized lenders in-house | Often a DIY process |
| Lot models to walk through | Yes, Portland and Snohomish | Rarely |
The Bottom Line
Custom tiny home builders have a place. If you have the time, the budget, a specific vision no production floor plan can match, and a plan for certification and placement, hire one. You'll get exactly what you want.
For everyone else, a dealer selling factory-built, ANSI A119.5 park model RVs is the faster, cheaper, lower-risk path. You get a finished home ready to move into, a manufacturer warranty behind it, nationwide certification, and a local in-house team that services what we sell.
