Cornerstone Construction Inc.

What Cornerstone Construction Inc. does

Cornerstone Construction Inc. (doing business as Cornerstone Inc. Custom Homes) is a family-owned design-build contractor founded in 1976 by Jim Brennan and headquartered at 761 N Thornton St, Post Falls, Idaho. The company serves property owners across the Inland Northwest — specifically North Idaho and Eastern Washington — with a single integrated point of contact from pre-design through project delivery, eliminating the fragmentation typical of separate architect-contractor engagements.

Core offerings include fully custom homes (with over 150 completed in the region), remodels and additions, commercial construction, and production homes, supplemented by in-house permit-ready design services priced at approximately half the cost of an architect and in-house finish carpentry for cabinetry and trim. The operating model is a project-based, quote-priced design-build service with no recurring revenue, distributed through a physical showroom, direct customer engagement, and a long-standing referral network of realtors, architects, structural engineers, banks, and lending firms. The company is privately held with concentrated family ownership (Jim Brennan as Founder/President, Levi Brennan as Vice President), lean in-house craft staff supplemented by a developed subcontractor network, and no disclosed institutional funding, acquisitions, or technology platform beyond a standard marketing website.
