For years now, the PNW has been ahead of the curve when it comes to reimagining basements and backyards. What used to be extra storage or unused space is now being transformed into something that adds both value and income potential. And the question that keeps bubbling up? Airbnb or ADU. Both can make sense, but the path you choose depends on what kind of commitment you’re ready for. Let’s take a closer look.
The allure of short-term rentals
There’s no denying the draw of Airbnb. In Portland, the average host earns about $2,400 per month with a steady occupancy rate of around 70% (AirDNA, 2024). In Vancouver and Southwest Washington, where nightly rates run a little higher, hosts average closer to $30,000 annually. For many, that extra cash is hard to ignore.
But it’s not as simple as snapping photos and listing your space. Portland, for instance, requires a Type A or Type B permit, inspections, and compliance with safety codes. And here’s the kicker: only about 22% of Portland’s active short-term rentals are actually permitted (City of Portland, 2023). Add in the upkeep, fresh linens, guest communication, surprise midnight requests, and you quickly realize hosting is as much a lifestyle as it is an income stream.
Some neighborhoods are also starting to raise eyebrows at the flood of Airbnbs. Concerns about affordability and keeping a more localized culture in tact have made short-term rentals a hot-button issue, while ADUs often feel like a quieter solution, adding density without the disruption to more permanent housing solutions
The staying power of ADUs
On the other side of the coin are accessory dwelling units (ADUs). Portland has been leading the charge here for over a decade, with permits for ADUs jumping from a handful in 2009 to more than 1,300 in a single year by 2016 (Portland Bureau of Planning & Sustainability). Today, a long-term ADU rental can bring in an average of $1,300–$1,700 per month, depending on location (Oregon Home Builders Association & Apartment List, 2024).
Clark County homeowners now have even more flexibility thanks to Washington’s HB 1337, which requires cities to allow up to two ADUs per lot in most urban areas. It’s a big shift, especially in a market where demand for rental housing remains strong and vacancy rates low.
Choosing your lane
In the end, it’s less about the square footage you’ve got and more about how you want to live with it. Airbnb can feel like a whirlwind, guests coming and going, a little extra sparkle in your bank account, and the occasional late-night message about where to find the wine opener. ADUs, on the other hand, are the steady drumbeat of one tenant, one lease, and rent that shows up on the same day each month.
Neighbors notice the difference too. Short-term rentals bring energy but sometimes raise questions about affordability and neighborhood feel. ADUs tend to blend in, adding housing without a fuss, often welcomed as part of the fabric of the block.
There’s no universal right answer. The “best” choice is the one that matches your bandwidth, your appetite for management, and your vision for the home you’re shaping. Around the PNW, basements, garages, and backyards are quietly becoming a bigger piece of the housing puzzle sometimes as cozy guest suites, sometimes as long-term homes. The opportunity is there either way.
Pro-tip: Every basement, backyard, and block tells a different story here in the PNW. What makes sense in Portland might look different in Vancouver or Beaverton, and that’s where we come in. We’re here to help you sort through the zoning quirks, crunch the numbers, and figure out whether short-term sparkle or ADU staying power is the right fit for your space.
