How Property Is Assessed in San Juan County
The San Juan County Assessor values real and business personal property under Colorado law, with a full reappraisal in odd-numbered years. Because the county sits at such extreme elevation — an average of 11,240 feet — nearly all property here is mountain terrain, historic mining-era buildings, and a small residential core in Silverton, rather than the mixed development seen in lower-elevation counties. Our guide explains how Colorado property tax works.
Each property has a unique parcel number, which is the fastest and most accurate way to pull up ownership, land size, building details, and tax records.
