Overview

The property includes two parcels at 315 & 321 Main St. 315 Main contains an approximately 3,570 sq. ft. building with approximately 798 sq. ft. of garage space. The building exterior is described as in fair to good shape, while the interior requires finishing to be ready for occupancy.

321 Main is a vacant lot. The property also has an individual well and water rights through the Idaho Department of Water Resources. The referenced water right number is 36-4229, with supporting documentation available in the docs tab.

This configuration may fit buyers looking to put finishing work toward a warehouse or storage-focused use for the existing building, with the adjacent vacant lot providing additional flexibility within the same ownership. Because the inside is not yet finished, prospective buyers should plan for tenant or user improvements to suit their specific operating needs. Water availability is supported by the stated well and water rights.
