Seven small, sharp utilities for the parts of public-notice work that waste an afternoon. Buffer-and-mail. List-and-print. Parcel-and-verify. Address-to-APN. A directory of every county's parcel REST URL. A city's zoning docket by address. A property's violation and permit history. They run in the browser. Nothing leaves your machine.
Drop a parcel GeoJSON, plant an address. Every owner inside the buffer ring is selected, deduplicated, and ready to print.
Bring your own list. Map columns once, dedupe, walk away with a print-aligned PDF. 30 labels per sheet. No realignment math.
Paste any county's ArcGIS® REST URL. The tool inspects the layer, learns its fields, and lets you query property records the way the assessor stored them. No signup, no proxy.
A directory of US county parcel ArcGIS REST endpoints. Find your county's URL, see supported search fields, and open it in Parcel Lookup with one click. Crowdsourced and verified.
Type a U.S. street address. The U.S. Census Geocoder pins it to a state and county; if your county is indexed, you go straight to Parcel Lookup with the REST URL pre-filled. Get to your APN in one hop.
Search a city's zoning and rezoning docket by address. Case status, proposed versus existing zoning, owner, and hearing dates, read live from the city's open data. Austin now, more cities coming.
Pull a property's code violations and building-permit history by address. The violation or permit, its status, the work, and the dates, read live from the city's open data. The record paid lookup sites charge for. Dallas, Chicago, Nashville.
If you have to mail written notice to every owner within 300-500 ft of a variance, use permit, or rezoning, the radius mailing list guide chains the tools above into one workflow: address → radius → affected-owner list → Avery 5160 labels. Built for planning consultants, land-use attorneys, and permit applicants, the same deliverable some jurisdictions call an abutters or adjacent-owner list.
The seven tools above run on data you already have. Bulk enrichment does the lookup for you: paste or upload a list of addresses and get the owner of record, parcel number (APN), and mailing address for each, then download as a CSV. Included on the Individual plan ($24/mo) and up.
The seven tools above run in your browser. The Parcel Atlas MCP server runs in your agent: point Claude, Cursor, or any MCP client at one endpoint and let it resolve addresses, geocode counties, and pull county REST URLs. Six discovery tools stay public; a paid or pay-as-you-go key adds enrich_address for one address, and a paid plan adds radius_owners for every owner parcel inside a radius.
Prefer code over an agent? The @urbankitstudio/atlas npm SDK ships the same county index for Node and the browser: look up a county by FIPS, slug, or state, and read its REST endpoint and searchable fields straight from your build.
Teams that need higher API rate limits, bulk county downloads as JSON or CSV, radius-notice seats for staff, and an SLA have a tier for that. Built for proptech, title, land-use law, and GIS consultancies.

Most users hit one of these three paths. The tools chain: output from one feeds the next.
