Notes
The County building card records 3 bedrooms, 3 bathrooms and 1,633 square feet of heated area for account R042234. Its 2026 notice limits the listed characteristics to the first building. These are County account and building-record figures, not an independent survey or determination of exclusive frontage, property boundaries or entrance allocation. Current condition, configuration and alterations should be confirmed through a property visit and current documents.

Map centered on the County address point linked to assessor account R042234 and County situs 3897 Lupine Drive #A. Google Maps labels the directions destination “3897 Lupine Dr Unit B”; this third-party label differs from the County account identification and remains unresolved. The verified County point is retained as an approximate account-linked location, not a surveyed boundary or verified #A residence entrance. Confirm access independently before visiting.

Photo: AI-assisted enhancement of a historical Eagle County exterior photograph; capture date unverified. The enhancement reconstructs and brightens roof seams, siding, garage-door panels, the shaded passage, vegetation, pavement and foreground rack detail. Visible garage-like frontage does not supersede the County’s NO GARAGE record or establish exclusive #A frontage or entrance allocation. This historical image is not a representation of current condition or construction status. View the unaltered County source photograph.
