Our Tools

Public Notice Radius Mailing List Generator

Generate mailing lists for public notice requirements. Upload parcel GeoJSON data, enter a project address, set a buffer distance (e.g., 500 feet), and automatically identify all property owners within the notification radius. Export as CSV or print-ready Avery 5160 labels.

Use cases: Zoning variances, conditional use permits, rezoning applications, subdivision plats, environmental reviews, historic preservation notices.

CSV to Avery 5160 Label Maker

Convert any CSV mailing list into print-ready Avery 5160 label sheets. Upload your spreadsheet, map columns to address fields, preview your labels, and download a PDF formatted for standard 30-label sheets (1" × 2⅝" labels).

Use cases: Public notice mailings, bulk mail campaigns, event invitations, holiday cards, business mailings.

Parcel & Property Lookup Tool

Connect to any county's ArcGIS Feature Layer and search parcels by APN, address, or owner name. Instantly retrieve property details, zoning designations, assessed values, mailing addresses, and ownership information—all from your browser.

Paste any ArcGIS REST Feature Layer URL (e.g., from your county GIS portal) and the tool automatically detects searchable fields. Results display all available parcel attributes with one-click copy and print support.

Use cases: Property research, title searches, zoning verification, public notice preparation, development feasibility analysis, neighborhood analysis.

About UrbanKit Studio

UrbanKit Studio was built by a planner who got tired of the clunky, expensive workflows involved in generating public notice mailing lists. What should take minutes—buffering parcels, pulling owner addresses, deduplicating, and printing labels—often takes hours using legacy GIS tools or expensive subscription software.

Our mission is to make essential planning tools accessible to everyone: small municipalities that can't afford enterprise GIS, solo practitioners handling their first variance application, and community members who want to participate in the planning process. Every tool is free, runs entirely in the browser, and requires no account or personal information.

We're actively building new tools and expanding coverage. If you have ideas or feedback, we'd love to hear from you.

Frequently Asked Questions

What is public notice radius notification?: Most cities and counties require that property owners within a certain distance of a proposed development be notified of upcoming public hearings. Typical distances range from 200 to 500 feet, though requirements vary by jurisdiction and project type (variances, CUPs, rezonings, subdivisions).
Where do I get parcel GeoJSON data?: Check your county assessor or GIS department—many offer free parcel downloads through open data portals. State GIS clearinghouses and services like Regrid.com also provide parcel data. If you have a Shapefile, convert to GeoJSON using mapshaper.org or QGIS.
What are Avery 5160 labels?: Avery 5160 is the most popular mailing label format in the US. Each 8.5" × 11" sheet contains 30 labels (1" × 2⅝" each) arranged in a 3×10 grid. They work with both inkjet and laser printers and are sold at office supply stores, Amazon, and Avery's website.
Is my data secure?: Yes. All processing happens entirely in your browser. Your CSV files, GeoJSON data, and generated PDFs never leave your computer. We don't store, transmit, or have access to any of your data.
How does the Parcel Lookup tool work?: Paste any ArcGIS REST Feature Layer URL from your county's GIS portal. The tool loads the layer's metadata to discover available fields, then lets you search by any field (APN, address, owner name). Results show all parcel attributes with one-click copy. It works with any county or municipality that publishes an ArcGIS REST service.
Can I use these tools on mobile?: Yes, UrbanKit Studio is fully responsive. However, for the best experience with the map-based Radius Notice tool, we recommend a desktop or laptop computer.
