Curious who owns the lot next to you in Hailey? The Hailey GIS map answers most of that, and it's free to use. Covered here for the town: which viewer to open, how to search it, and what to double-check with records around Carey.
Opening the Hailey GIS map: start here
In most places the county maintains the parcel layer, and for Hailey that means the Idaho statewide Parcels layer in ArcGIS Map Viewer.
Opening the official parcel viewer
Property in and around Carey can be looked up on the Idaho statewide Parcels layer in ArcGIS Map Viewer, a viewer that needs no account. Out toward Sun Valley, type a street address, an owner's name or a parcel number, and the viewer zooms to the match. In and around Ketchum, the record panel typically gives the owner of record, assessed acreage, the parcel number and in many cases the last transfer.
Hailey, ID: the basics
Hailey is part of Blaine County, Idaho, so its parcels are on the county's map. As the county seat, Hailey hosts the courthouse, which puts the County Recorder (the county clerk serves as recorder) close by. Local government in Hailey handles matters such as zoning, permits and utilities inside its limits, but the county runs assessment and recording. Acreage past the city limits toward Carey often falls under county rules, not municipal ones.
What the map can't tell you
Parcel lines are drawn for taxes, not surveyed, so a tree line near Ketchum may sit several feet off the line on screen. For acreage around Sun Valley, records update in batches, so a deed recorded last month can take weeks to appear.
Sections, lots and bearings
Idaho uses the Public Land Survey System, so rural legal descriptions near Carey cite section, township and range. A standard section is about one square mile, roughly 640 acres, with 36 sections to a township, though corrections make some sections near Sun Valley odd-sized. Write down the legal description for the tract near Ketchum when you talk to a surveyor.
Three ways to find a parcel
Acreage around Sun Valley might not have a street number, which means panning to it and clicking. For a home near Carey, searching by parcel number never misses, and it carries over to every office in the county.
Land on the county line
Blaine County meets Bingham County, Butte County, Camas County, Cassia County, and Custer County, and each of those keeps its own parcel map. A tract near the line by Sun Valley can be split across two assessors' files, so look at the adjacent map too. Our state page lists every bordering county map for Idaho.
Printing and saving
Print or screenshot the parcel near Ketchum with its ID visible, so you have it when calling an office.
Field tips
Most viewers work in a phone browser, useful out on a road near Ketchum, though signal can drop in rural spots. A printout of the tract near Ketchum helps when you meet an owner or agent.
Who handles what
Deeds, mortgages and recorded plats for land near Ketchum are with the County Recorder (the county clerk serves as recorder), sometimes only in person. Zoning, permits and septic questions near Carey are for the local planning and health departments, and the answer depends on jurisdiction.
Layers worth turning on
Toggling imagery near Sun Valley helps you see where buildings sit inside the lines.
Inside the parcel card
Recent sales on nearby lots in the town are a useful starting point; they're not an appraisal, at least around Ketchum.
The paper trail behind a parcel
Before you sign anything, pull the recorded deed through the County Recorder (the county clerk serves as recorder); the parcel map near Ketchum only summarizes it. Long-held tracts near Sun Valley may sit on several deeds, so a title company is worth hiring if money is changing hands.
Getting your bearings
Hailey serves as the county seat, where most land records are kept. You'll also find Bellevue, Sun Valley, Ketchum, and Carey, each with its own cluster of lots. About 25,041 people call Blaine County home (Census estimate, 2023) on about 2,638 square miles. Blaine County was formed in 1895, which matters when you trace an old farm's title. Features like Craters of the Moon National Monument are easy to spot when you zoom out from Sun Valley.
When the map won't load
When the map won't open around Bellevue, try a desktop browser or clear the cache; links occasionally change, and our directory page keeps the current one.

Not a survey. County GIS and tax parcel maps are assessment and planning layers. They are not a substitute for a recorded plat, deed, or licensed survey, especially for fences, setbacks, or boundary disputes.
