Researching Gem County land for sale
Open tracts on the Gem County ArcGIS parcel map usually carry little or no building value, a quick filter for ground near Emmett.
Where the parcel data lives
The public parcel map for this area is the Gem County ArcGIS parcel map, and no login is needed to use it. Out toward Emmett, put in a street address, an owner's name or a parcel number, and the matching parcel lights up. For land near Ola, copy the parcel ID while you have it open; each office in the county asks for it first.
Sections, lots and bearings
Idaho uses the Public Land Survey System, so deeds around Boise National Forest reference sections and townships. Each section is nominally a mile square, about 640 acres, and a township holds 36 of them, though corrections make some sections near Emmett odd-sized. Write down the legal description for the tract near Letha before you request a deed or survey.
Road frontage and size
Listed acreage is a tax figure, and a survey sets what you're really buying near Letha.
Before you lean on the lines
Acreage on the record is a tax-roll number; just a licensed surveyor establishes the real boundary on land around Sweet. For land near Letha, records update in batches, so a deed recorded last month can take weeks to appear.
Which office to call
Recorded documents for a parcel near Ola sit in the index kept by the County Recorder (the county clerk serves as recorder), sometimes only in person. Questions about what you can build around Ola go to planning, building or health offices, depending on whether the land is inside town limits.
Where the recorded documents are
The map is an index, not the title: deeds, subdivision plats and easements for land near Boise National Forest are kept by the County Recorder (the county clerk serves as recorder). If the land is near Letha, have ready the book and page listed on the parcel record to skip a name search.
When a parcel crosses a boundary
Gem County borders Ada County, Adams County, Boise County, Canyon County, and Payette County, all with their own assessor records. A tract near the line by Emmett may show up across two assessors' files, so check the neighboring map as well. With a lot near Ola, the Platbookmapper state page lists each bordering county map for Idaho.
Flood, wetlands and soils
Check the tract near Emmett on FEMA's Flood Map Service Center for mapped flood zones; the National Wetlands Inventory mapper gives a first look at wetlands.
