Most discretionary land-use approvals require you to mail written notice to every property owner within a set distance of the project — and to prove you did. These free tools turn a project address into a radius, an affected-owner mailing list, and a sheet of labels.
If you run entitlements for a living — a planning consultant, a land-use attorney, an expediter, or an applicant doing it once for your own permit — the notice mailing is the unglamorous step that can reset your hearing date if you get it wrong. The owner list has to be current, the radius has to match what the ordinance says, and the proof of mailing has to hold up. The workflow below is the same one the radius notice tool runs, laid out start to finish. Everything is browser-side and free; nothing you upload leaves your machine.
Drop your parcel GeoJSON, plant the project address, set the radius in feet. Every owner inside the ring is selected and deduplicated, ready to export as a CSV or print as labels.
Start from the subject property — the parcel the variance, conditional use permit, rezoning, or subdivision applies to. You need its location to center the radius. A street address is enough; the parcel number (APN) helps you confirm you have the right lot.
Find My Parcel NumberDownload the parcel polygons for the area from your county's GIS as GeoJSON. Most counties publish an ArcGIS REST endpoint that returns parcel geometry plus the owner and mailing-address fields you'll mail to.
County Parcel LookupSet the notification distance your jurisdiction requires — commonly 300 or 500 feet — and let the tool select every parcel whose boundary falls inside the ring. It deduplicates owners who hold more than one parcel so nobody gets two envelopes.
Radius Notice GeneratorExport the deduplicated owner list as a CSV, or print it straight onto Avery 5160 sheets — 30 labels per page, aligned for a laser or inkjet printer. Bring your own list from step 3, or one you already maintain.
CSV to Avery 5160 LabelsYou file a steady stream of entitlement applications and need a repeatable way to produce a defensible owner list for each one — without paying per record to a data vendor.
Notice is a due-process requirement, and a missed owner is grounds to challenge an approval. You want the current owner of record straight from the county source, on the radius the ordinance specifies.
You're doing this once, for your own variance or use permit, and the city handed you a notice requirement with no instructions. The workflow above gets you from address to labels in an afternoon.
There is no single national notice distance. A setback variance might require notice to owners within 300 feet; a conditional use permit or a rezoning often pushes that to 500 feet or more, and some jurisdictions measure from the property line while others measure from the nearest structure. Confirm the figure and the measurement method in your local zoning ordinance before you mail — the radius tool takes whatever distance you give it, but only you can supply the right one.
