Construction Supplies & Services

We make building easy!


Franklin Building Supply was founded as a lumberyard in Boise, Idaho in 1976.  All these years later, Franklin remains one of the few locally owned, and the only employee owned, building supply company in the area. 

With twelve full-service lumberyards, six door shops, two truss plants and five beautiful design centers, we have unmatched reach and expertise. 

Our local ownership allows us to be nimble and make our decisions with our customers needs being the top priority. 

Our ability to get what you need delivered when you need it, at a competitive price, is second to none. 

We look forward to showing you why experience, quality products and incredible service makes us the building partner for so many across southern Idaho and northern Nevada.
