Portland's ASTR Permit Paper Trail: The Exact Documents You Need Before You List

Portland enforces one of the most structured short-term rental permit systems in the Pacific Northwest — and the city is not shy about using it. Hosts who list on Airbnb or VRBO without a valid Accessory Short-Term Rental (ASTR) permit risk platform delisting, permit denial, and referral to the city's Revenue Division for transient lodging tax violations. The city maintains a public Short-Term Rental Registry at PortlandMaps.com, and platforms cross-reference that registry to verify permit numbers. If your number doesn't appear — or doesn't match exactly — you can be removed from the platform without warning.

Understanding what Portland requires before you submit your application is the difference between a smooth approval and weeks of back-and-forth with the Bureau of Development Services. This guide walks you through the permit types, the documents you'll need, the application process, and what happens if you skip any of it. For specific fees and current processing timelines, verify directly at portland.gov/ppd/astr-permits.

Portland's Two-Track ASTR Permit System: Type A and Type B

Portland divides short-term rental permits into two categories based on the scope of your operation. A short-term rental (STR) in Portland is defined as a residential property — or portion of one — rented for fewer than 30 consecutive days. Before you gather a single document, you need to know which permit type applies to your situation, because each track has different requirements and a different approval path.

Type A ASTR Permits apply to hosts renting one or two bedrooms within their primary residence. This is the standard permit for hosts who live in the home and rent out spare rooms or a portion of the dwelling. Type A is administered directly through the Bureau of Development Services (BDS) and is the more common permit type for individual hosts.

Type B Conditional Use applies to more complex situations — typically where the rental involves a greater portion of the property or does not fit neatly within the Type A definition. Type B requires a conditional use review, which is a more formal land use process with its own documentation standards and timelines.

If you are unsure which category fits your property, contact the Bureau of Development Services at 1900 SW 4th Ave. In-person services are currently available on Tuesdays and Thursdays from 8 a.m. to 4 p.m., with virtual appointments available daily. Many permit services are also available online 24 hours a day through the city's development portal. Confirm current hours at portland.gov/service-locations/development-services-center before you visit.

How to Apply: Building Your Portland ASTR Document Package

Portland's permit application process requires hosts to submit documentation that demonstrates their property qualifies under the applicable permit type. Because our verified source data does not include the city's current complete document checklist — which can change — the single most important step you can take right now is to download the current application instructions directly from portland.gov/ppd/astr-permits/1-2-bedrooms-type-permits before you prepare anything.

That said, based on how Portland's ASTR program is structured, hosts applying for a Type A permit should be prepared to demonstrate the following types of information during their application:

\n
• Proof of primary residency. Portland's Type A permit is tied to the host's primary residence. You will need documentation showing that the property is your principal home — not an investment property you manage remotely.
\n
• Property address and description. The application will require a clear identification of the property and the specific space being rented — whether that's one bedroom, two bedrooms, or another defined area.
\n
• Permit number for registry listing. Once issued, your permit number must appear on the city's public Short-Term Rental Registry and must be displayed exactly as issued in any platform listing. A single digit mismatch between your permit number and the registry entry is enough for a platform to delist you.
\n
• Transient lodging tax registration. Portland hosts are required to collect and remit transient lodging tax. The Revenue Division handles this separately from the permit itself. Contact the Revenue Division at (503) 865-2857 or by email at TLTax@portlandoregon.gov for current registration requirements and rates. Do not assume your BDS permit automatically handles tax compliance — it does not.
\n

For Type B Conditional Use applications, the documentation requirements are more extensive and involve a formal land use review. Contact BDS directly at (503) 823-2633 to understand what that process requires for your specific property.

STR Comply monitors Portland's permit page weekly and sends you an alert the moment requirements or the application process changes — so you never scramble to find out what's current.

After Approval: Your Ongoing Obligations as a Portland STR Host

Getting your ASTR permit is not a one-time task. Portland requires hosts to maintain active compliance on an ongoing basis, and the city's public registry makes it easy for both platforms and neighbors to check whether your permit is current.

Permit renewal. Portland ASTR permits require periodic renewal. The registry tracks renewal dates publicly at portlandmaps.com. Contact the Bureau of Development Services for your specific renewal deadline and verify the current renewal fee at portland.gov/ppd/astr-permits before your permit lapses.

Registry accuracy. Your permit number must match exactly what appears in the city's Short-Term Rental Registry. If you update your listing, change platforms, or re-list after a gap, double-check that the permit number displayed in your advertisement matches the registry character for character. Portland platforms verify against this registry, and a mismatch — even a minor formatting difference — is treated as a non-compliant listing.

Transient lodging tax remittance. Hosts are responsible for collecting and remitting transient lodging tax on all short-term rental income. This obligation continues for as long as you operate. The Revenue Division's Transient Lodging Tax team can be reached at TLTax@portlandoregon.gov or (503) 865-2857. Verify the current rate and filing schedule directly with the Revenue Division — do not rely on third-party estimates, which are frequently outdated.

Permit type accuracy. If your rental situation changes — say, you begin renting more of the property, or it is no longer your primary residence — your permit type may need to change as well. Operating under the wrong permit category is treated the same as operating without a permit.

Hosts using STR Comply get a personalized compliance checklist for their property type, including renewal reminders tied to Portland's registry data, so nothing slips through the cracks.

What Portland Does to Hosts Who Skip the Permit Process

Portland has built its enforcement system around two overlapping mechanisms: platform verification and the public registry. Together, they create a compliance environment where unlicensed hosts are increasingly visible and increasingly at risk.

Platform delisting. Airbnb and other platforms operating in Portland are required to verify that hosts hold a valid ASTR permit. If your permit number does not appear in the city's Short-Term Rental Registry, or if the number in your listing doesn't match the registry exactly, the platform can remove your listing. Portland's own guidance for hosts who have been delisted instructs them to first check the registry — confirming this is the city's primary enforcement lever.

Revenue Division referral. Hosts who operate without registering for transient lodging tax — or who operate under the "Other" permit type designation — are directed to the Revenue Division rather than BDS. The Revenue Division has authority over tax compliance separately from the permit process. Failing to register for and remit transient lodging tax while operating an STR is a distinct violation from operating without an ASTR permit, and the city can pursue both simultaneously.

Common application mistakes that cause rejection or delays:

\n
• Applying for a Type A permit when the property is not your primary residence
\n
• Listing a permit number before the permit is formally issued and appears in the registry
\n
• Failing to register separately for transient lodging tax under the assumption the BDS permit covers it
\n
• Allowing a permit to lapse and continuing to operate under an expired permit number
\n
• Mismatched permit numbers between the registry and the platform listing
