Short-term rental compliance data
Verified data on short-term rentals that appear to operate without a valid local registration.
Short Stay Data is an independent data service. Each month we find active short-term rental listings, check them against public city and county records, and deliver documented, verifiable records to the people working on housing, enforcement and accountability.
Currently covering Los Angeles, with more markets on request.
Why it matters
Homes kept in the long-term market
Many cities and counties register short-term rentals so they don't take housing out of the long-term rental market. Unregistered listings are hard to see without address-level data.
Rules that can actually be applied
Enforcement depends on evidence. We assemble the public-record trail (listing, address, registration status) so the responsible local office can review it and act through its own process.
A level field with hotels
In many markets, registered short stays collect the same local hotel or occupancy tax that hotels do. Where the data supports it, we estimate the hotel-tax equivalent of unregistered activity so its fiscal impact can be read in context.
How it works
Find. Verify against public records. Deliver.
A listing is only included once it passes a documented verification process. If a fact can't be confirmed from a public source, it doesn't go in the dataset.
Find
We review publicly visible short-term rental listings on major booking platforms in each market we cover.
- Records the registration number shown on the listing, if any
- Saves an archived copy of the public listing page
Verify against city and county records
Each listing is checked against the local registration records that are publicly available and against public property records.
- Registration number missing, invalid, expired or mismatched
- Address confirmed and, where possible, matched to a parcel
- A person reviews every record before it is delivered
Deliver
Verified records are delivered monthly as a clean, documented dataset with supporting evidence attached.
- CSV / spreadsheet plus evidence files
- Change notes: new, resolved and removed listings
- Scoped by area, district or building
Who it's for
Built for the people who need reliable facts
Each dataset can be scoped to a market-wide view, a district or neighborhood, or a single building.

Sample record
What a verified record contains
Every record describes a listing and a property, not a person. Each field is backed by a source you can check yourself.
- Listing: platform, public listing ID, URL, capture date and an archived copy of the page.
- Address: confirmed street address and parcel number where available, with the method used to confirm it.
- Violation type: what the public record shows, for example no registration number displayed, or a number that is invalid, expired or registered to a different address.
- Supporting public records: references to city or county registration lookups and property records.
- Status history: first seen, last seen, and whether the issue has been resolved.

Data principles
Verifiable facts only
We report what public records show. A record says a listing appears to lack a valid registration; it does not draw conclusions about anyone's intent. Only the responsible city or county authority can decide whether a violation has occurred.
Sourced and reproducible
Every field cites a public source and capture date, so anyone with the record can check it independently.
No personal information sold
We describe listings and properties. We don't compile or sell hosts' names, contact details, profiles or other personal data.
Neutral by design
Records use neutral language like "appears to" and "no matching registration found", and they're kept separate from any opinion or advocacy.
Human-reviewed
Automated matching is followed by a manual check. Cases we can't confirm are left out rather than guessed.
Corrections process
Anyone, hosts included, can email a correction request with supporting information. We review it, update or remove the record if it's wrong, and note the change in the next release.
Lawful, responsible use
Clients agree to use the data lawfully, for purposes such as policy work, compliance, reporting and referral through official channels.
What we don't do
- Sell or publish hosts' personal information
- Make legal determinations of violations
- Access non-public or password-protected data
- Contact, confront or publicly name hosts
- Include records we cannot verify from public sources
- Support harassment or any unlawful use of the data
