Union County Auditor Help: Choose the Correct Official Tool Before You Search, Pay or File
Most users searching for the Union County Auditor want property records, Beacon parcel lookup, GIS maps, tax payment help, homestead exemption, Board of Revision guidance or deed records. These tasks are related, but they do not all happen in the same office.
Use the Auditor’s property search tools when you need real estate or appraisal information, parcel details, building sketches, GIS mapping, property tax information, tax levy data and general land information.
Use the Treasurer when your question is about paying property taxes or tax collection. Use the Recorder when you need deeds, mortgages, official record images, grantor/grantee indexes or chain-of-title documents.
Homeowners
Search your parcel, review appraisal information, check building sketches, understand tax rollbacks and use Homestead resources before calling the office.
Buyers and agents
Use Beacon property records, comparable sales, GIS maps, Recorder records and Treasurer tax answers together before closing or advising a client.
Researchers
Use Beacon, GIS Enterprise Data Portal, historical maps, survey records and Recorder indexes for deeper public property research.
Union County Beacon Property Search by Parcel, Owner, Address, Sales and Comparable Records
Union County uses Beacon Property Search as the main public-facing property search application. The official county page says Beacon includes parcel search, comparable sales search, property tax estimator features, reports, export capabilities, additional map applications and more.
Users often search “Union County Auditor property search,” “Union County Ohio property records,” “Union County parcel search,” “Union County owner search,” and “Union County Beacon property search.” The safest route is the official county Property Search Tools page or the linked Beacon application.
1
Open the official Beacon Property Search
Use the official county-linked search tool.
▾
Open the Union County Beacon Property Search application. This is the practical starting point for owner, address, parcel, appraisal, comparable sales, reports and map-connected property research.
Official search: Union County Beacon Property Search
2
Search with the least confusing detail first
Parcel number is best when available.
▾
If you have a parcel number from a tax bill, prior record, closing document or deed reference, search by parcel first. Parcel number is usually more precise than owner or address search.
If you do not have the parcel number, start with owner name or address. Remove punctuation, directions, street suffixes or extra words if the exact search does not return the property.
3
Use comparable sales for value research
Useful before buying or filing a value complaint.
▾
Beacon includes comparable sales search capabilities. Use this when reviewing a purchase, preparing a Board of Revision complaint or checking how nearby similar properties sold.
Do not rely only on one sale. Compare location, property type, size, condition, sale date and whether the transfer appears to be a normal open-market sale.
4
Open the property record and review all tabs
One record can include multiple useful sections.
▾
After opening a property record, review appraisal details, tax information, building sketches, sales data, land information, maps and report options. Save the parcel number for use on other county tools.
Best search trick
If a full address fails, search only the street number and core street name. If owner search fails, try the last name only or the most unique part of the business/trust name.
Important warning
Property search data is useful for public research, but legal, tax, lending, title and closing decisions should always be verified through official offices and professional advice where needed.

Union County GIS Mapping, Parcel Viewer, Aerial Photography and Political Boundaries
Union County GIS Mapping helps users view parcel map information, parcel boundaries, aerial photography and political boundaries. It is useful when an address search is unclear or when you need visual parcel context.
The county also links to a Union County Parcel Viewer and GIS-related data tools. Use these for map research, but do not treat online map lines as a legal survey or final boundary opinion.
GIS Mapping
Best for parcel boundaries, aerial photography and political boundary context.
Parcel Viewer
Useful for map-based search by account/R numbers, UPC and E911 address data.
Survey caution
GIS is helpful for research, but it is not a professional survey or legal description.

Start with county-linked GIS resources.
▾
The GIS Mapping page describes a tool for parcel map information, parcel boundaries, aerial photography and political boundaries.

Review your property value first
