Everything browser-side stays free. The paid tiers are for the lookups you'd otherwise do by hand, a list of addresses in and owner and parcel number out, and for teams who want a production parcel API without a sales call, a contract, or a four-figure minimum to clear.
UrbanKit Studio indexes the parcel REST endpoints of 155 US counties and turns them into working tools. The atlas, the browser utilities, the MCP server, and the npm SDK are free and stay free. The paid tier is the resolution work on top of that data, and you can start it from this page.
Paste a list of addresses, or upload a CSV, and get the owner of record, the parcel number (APN), and the mailing address for each, then download the whole set as a CSV. It's the bulk version of the work the free Parcel Lookup does one parcel at a time, run against the public county layers.
Working a public hearing instead of a list? The Radius Notice tool uses the same plan to auto-pull every owner inside a distance ring, straight to deduplicated CSV and Avery 5160 labels.
Just need one property at a time? The free Find My Parcel Number tool turns a single street address into its county APN, and the public notice mailing guide walks one project through the whole notice workflow, no account, nothing stored.
Who it's for: realtors, solo investors, contractors, and small title or land-use teams who need to know who owns a list of properties, without paying for a full prosumer REI platform, and its stack of add-ons, to get there.
For the developer or small shop building on parcel data: a higher daily lookup limit, bulk county exports as JSON or CSV, multiple API keys, and higher MCP rate limits. The same address-to-owner engine the tools run on, exposed for your own software.
Who it's for: proptech platforms, GIS consultancies, and engineers who'd rather call an endpoint than scrape forty county portals. Where comparable production access usually means a sales call or a four-figure minimum, this tier is a card and an API key. Teams that need volume, an SLA, and a named contact move up to Enterprise.
Convert a CSV to labels, buffer a parcel for a notice mailing, or query one county REST layer you already found. No account, nothing leaves your browser.
Hand it addresses and it finds the owner, the APN, and the mailing address for each, across the indexed counties. The part you'd otherwise do by hand, in bulk.
Month to month, a 7-day trial for first-time subscribers, and a one-click cancel in the Stripe portal. The data was always public, you're paying for the resolution, not a lock-in.
The free tools run in your browser on data you already have, a CSV you exported, a GeoJSON file, a county REST URL you found. The paid tools do the lookup for you: hand them a list of addresses and they return the owner of record, the parcel number, and the mailing address for each, drawn from the public county layers. You pay for the resolution work and the coverage. The data itself was already free.
Individual, at $24 a month, is the entry point, it covers bulk address-to-owner enrichment plus single lookups and radius queries. Pro ($149/mo) raises the daily limit and adds bulk county exports and multiple API keys for a developer or small shop. First-time subscribers get a 7-day free trial; card details are required to start it, and you can cancel any time before it ends without being charged. If you've subscribed before, billing starts straight away.
No. Bulk Parcel Enrichment is a browser tool: paste addresses or upload a CSV, and download the enriched results as a CSV. If you do build software, the same data is available through the Parcel Data API and the MCP server, the API tier is what Pro and above unlock.
County and municipal ArcGIS parcel layers, the same public sources the free atlas indexes across 155 counties. We don't resell a third party's database; we resolve each address against the authoritative public layer for its county. When a county doesn't publish owner names, we say so on that row rather than guessing.
The price is public, so you can start today without a sales call. It's month to month, with no contract or minimum to clear. And every county endpoint is re-verified every two hours with the status public, so you can see the data is current instead of taking a nationwide claim on faith. One honest caveat: UrbanKit resolves owner of record, APN, and mailing address. It doesn't cover phone or email skip-tracing, valuation estimates, or title history. If your core need is one of those, keep the specialist tool for that piece; this replaces the owner and mailing-address layer under it.
Yes. Plans are month to month with no lock-in, cancel from the Stripe billing portal in your account and you keep access through the end of the period. The underlying data was always public. You're paying for the convenience, and you can walk away anytime.
