The official viewer behind the Emmett GIS map
In most places the county maintains the parcel layer, so for Emmett the go-to is the Gem County ArcGIS parcel map.
The viewer Gem County publishes
Begin with the Gem County ArcGIS parcel map; it maps each assessed parcel around Ola and Letha. If the land is near Letha, put in a street address, an owner's name or a parcel number, then pick the result to center the map on it. Out toward Ola, the record panel normally shows the owner of record, acreage on the tax roll, the parcel number and in many cases the last transfer.
Deeds, plats and who keeps them
When the details count, pull the recorded deed through the County Recorder (the county clerk serves as recorder); the parcel map near Letha only summarizes it. Around Letha, have ready the book and page listed on the parcel record to skip a name search.
Which office to call
Anything recorded against property around Letha sit in the index kept by the County Recorder (the county clerk serves as recorder), usually searchable by name or document number. Questions about what you can build around Letha go to planning, building or health offices, depending on whether the land is inside town limits.

Where Emmett fits in
Emmett sits in Gem County, Idaho, so its parcels are on the county's map. Emmett is also the county seat, so deeds and plats are filed in town. Near Ola, the municipality handles things like zoning, permits and utilities for lots inside the boundary, while the county keeps the tax map. Acreage past the city limits toward Ola usually follows county rules instead.

Acreage around Ola might not have a street number, so pan the aerial and click the lot. Around Letha, searching by parcel number never misses, and it's printed on tax bills.

Aerials, labels and overlays

On site with the map
Most viewers work in a phone browser, useful out on a road near Letha, so load it before you lose signal. A saved image of the lot near Letha and its lines is a good backup.
Before you lean on the lines
The acreage figure is a tax-roll number; just a licensed surveyor sets the real corners on land around Ola. Out toward Letha, owner names and values update on a schedule, so a deed recorded last month might lag behind.

Print or screenshot the parcel near Ola with its ID visible, which helps later when you ask the assessor or a title company.
Inside the parcel card
Recent sales on nearby lots around Ola give a rough idea of values; they're not an appraisal.
