A radius mailing list is every property owner within a set distance of a parcel. The abutters, the adjacent owners, the people a city makes you notify before it signs off on a project. Most discretionary land-use approvals require you to mail them written notice, and to prove you did. These free tools turn a project address into the radius, the owner mailing list, and the labels.
The same list goes by different names depending on where you practice and why you need it, an abutters list in New England, an adjacent-owner list on a subdivision plat, a certified list when the county wants proof. The job underneath doesn't change: take a subject parcel, reach out a fixed distance, and collect the owner of record and mailing address for every parcel inside the ring. The radius notice tool does that part; the workflow below lays it out start to finish, the same way the tool runs it.
Enter the project address, set the distance in feet. Every owner inside the ring comes back deduplicated, export a CSV or print Avery 5160 labels. Auto-query your county's own parcel data, or upload your own GeoJSON for free.
One row per parcel whose boundary falls inside the radius, carrying the owner of record and the mailing address the assessor has on file. That mailing address is often not the property itself. Plenty of owners live elsewhere, and the notice has to reach where they actually get mail. Owners who hold more than one parcel inside the ring are deduplicated, so nobody gets two envelopes and you don't pay twice for postage and label stock.
New England usage, statutory in Massachusetts: the direct abutters plus owners within 300 feet of the property line, often including abutters to the abutters.
The owners whose parcels touch or sit near the subject lot. Common phrasing on plat and subdivision applications.
What a planning department calls the owners it requires you to notify before a hearing, usually defined by a radius in feet.
A radius list the jurisdiction wants certified by the assessor, or one you mail certified for a provable record. Same owners; a stricter standard of proof.
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, or let the tool auto-query the county layer for you. Either way you get the 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 the tool selects every parcel whose boundary falls inside the ring, then collapses owners who hold more than one lot down to a single row.
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 produce an owner list for every entitlement you file. You need it current, from the county source, on the exact radius the ordinance names, and you need it repeatable.
You are doing this once, for your own setback variance or use permit, and the city handed you a notice requirement with no instructions. You want the list and the labels, today.
Notice is due process. A missed owner is grounds to challenge an approval, so you want the owner of record straight from the assessor, not a resold aggregate that lags reality.
Plats, lot-line adjustments, and easements carry their own adjacent-owner notice rules. You need the abutters tied to the parcels you are already working in.
You run notice across several projects and jurisdictions at once. A per-record data bill scales badly when one rezoning can touch hundreds of owners.
The manual way is an afternoon: find the county GIS portal, work out which layer holds the parcels, draw a buffer in their viewer, export, then clean the columns and dedupe owners by hand in a spreadsheet. Data vendors skip the labor but bill per record, which adds up fast when a single rezoning touches hundreds of owners. The radius tool sits in between.
How far you reach is set by your jurisdiction, not by us. A setback variance might require notice within 300 feet; a conditional use permit or rezoning often pushes that to 500 feet; larger projects can reach 1,000 feet or more. Some ordinances measure from the property line and some from the nearest structure, and a few extend past the immediate abutters to the next tier of owners. Check both the distance and how it's measured in your local code before you mail. Notice sent on the wrong radius is grounds to challenge the approval. The tool buffers whatever number you enter; getting that number right is the part only you can do.

A list of the owners of every parcel within a fixed distance of a subject property, with the mailing address for each. It is the list a local government typically requires you to notify before it acts on a land-use application.
In New England, and by statute in Massachusetts, an abutters list is the direct abutters plus owners within 300 feet, sometimes including the abutters to those abutters. It is a radius mailing list with a specific, codified radius. The radius tool builds it the same way: set the distance, get the owners.
Open the radius notice tool, enter the address, set the radius to 500 feet, and run it. On the Individual plan it auto-queries your county's parcel layer for the owners; on the free path you upload parcel GeoJSON and it selects every owner the ring touches. Either way you export a deduplicated CSV or Avery 5160 labels.
The owners are the same. "Certified" refers to the standard of proof , a list certified by the assessor's office, or one you send by certified mail for a provable record. The radius tool produces the owner list; certification is a step you take with the county or the post office.
No. If you already have parcel GeoJSON, most counties publish it free , the upload path is free and runs in your browser. The auto county lookup, which pulls the owners for you with no GeoJSON required, is included on the Individual plan. To find your county's parcel endpoint, start with Find My Parcel Number or the county parcel REST atlas.
The tool that builds the list: buffer a parcel, select every owner inside the ring, export deduplicated.
