Opening the Ada GIS map
In most places the county maintains the parcel layer, and for Ada that means the Hardin County Beacon site.
Where the parcel data lives
Begin with the Hardin County Beacon site; it includes each assessed parcel in the county, Patterson included. For land near Patterson, type a street address, an owner's name or a parcel number, then pick the result to center the map on it. For a tract near Kenton, write down the parcel ID from that panel; each records desk in the county asks for it first.
Printing and saving
Save a screenshot of the lot near Alger and its record panel, so you have it when calling an office.
Getting answers from the right desk
Anything recorded against property around Patterson sit in the index kept by the County Recorder, often with an online index. Questions about what you can build around Dunkirk are for the local planning and health departments, town or county, depending on location.
City limits and county records

With a lot near Kenton, the municipality handles things like zoning, permits and utilities for lots inside the boundary, and the county still keeps the parcel and deed records. Land beyond the city limits toward Patterson often falls under county rules rather than the town's.
Searching the map

Using it on a phone
