MONTERA

Modular Homes and ADUs in Boise and the Treasure Valley

Ada County, Idaho

Boise is one of the fastest-growing metros in the country, and land costs have made ADUs increasingly attractive for homeowners and investors. The Montera Borah — starting at $138,000 — is one of the most competitive factory-built ADU solutions available in Ada County.
