Search for a Property

You can use Allen County GIS to locate a parcel using an address or property owner’s name.

For a basic property search:

Open Allen County iMap.
Choose the appropriate map viewer.
Enter the property address or owner name.
Select the parcel.
Review the available property and map information.

Allen County’s own instructions allow searches by project address or parcel owner name.

Property Lines

GIS can be useful for getting a general idea of where parcel boundaries are located, but the lines shown on the map should not be treated as a professional property survey.

The Allen County Surveyor’s Office does not locate private property lines or perform private property surveys. Exact private property lines must be established by a professional land surveyor.

This is especially important before:

Installing a fence
Building a garage or shed
Adding a driveway
Resolving a boundary dispute
Building close to a property line

If the exact location of a boundary matters, use a professional land survey rather than relying solely on the GIS map.

Property Assessment Information

If you’re primarily looking for assessed value, property characteristics or comparable sales, the Assessor’s property tools may be more useful than the general map.

The Allen County Assessor provides COMPS — Comparable Online Multiple Property Search. It includes:

Property information
Comparable sales
Property record cards
Form 11 assessment notices
Aerial imagery
Property lines
Zoning information
Voting information

The Assessor currently identifies COMPS data as 2026 payable 2027.

If you only need a Property Record Card, Allen County also provides a separate search by owner name, property address, or parcel number.

→ Search Property Record Cards

Looking for Property Taxes?

If you’re trying to find a tax bill, tax amount, deductions, or payment information, use Allen County’s Public Access Tax Information (PATI) system rather than the general GIS viewer.

PATI can be searched by owner name, property address, Tax ID number, or billing duplicate number.

Who Maintains the GIS Property Boundaries?

The Allen County Auditor’s Office maintains property boundary information on the county GIS system as part of its responsibilities involving real-property ownership and taxation.

For assessment questions, however, contact the Allen County Assessor.

Before You Use GIS Information

Keep in mind:

GIS boundaries are not a substitute for a professional land survey.
Different viewers provide different map layers.
Some property information may not update immediately.
Property Record Cards involving transfers or value changes are updated once per month.
Check zoning with Planning Services before relying on a map for a building project.
Use official recorded documents when legal ownership or boundaries are important.

Local Tips

Not sure which map to use? Start with the General Viewer. For a specific task, switch to the DPS Viewer for zoning or the Engineering Viewer for drainage and infrastructure information.

Looking for assessed value or comparable sales? COMPS is a better starting point than the general map.

Looking for your tax bill? Use PATI instead of searching through the general GIS viewer.

Trying to determine exactly where a property line is? Don’t rely solely on the GIS line. Use a professional land survey when exact boundaries matter.
