About Calframe Construction

Calframe Construction Inc. is a second-generation wood framing company serving the entire Bay Area. Founded and led by Mark Muhn, Calframe has built a solid reputation grounded in craftsmanship, accountability, and integrity.


From large-scale multifamily developments to custom homes, Calframe is trusted by developers, builders, and general contractors who demand consistent quality, clear communication, and dependable results.


Our approach is simple: do honest work, communicate clearly, and deliver what we promise.


That commitment has made Calframe a go-to framing partner for some of the Bay Area’s most respected builders.

Built for Two Types of Residential Projects

Calframe Construction supports residential projects at very different scales. To serve each properly, our framing services are structured around two primary project types.

House under construction; wooden frame and roof trusses on dirt, blue sky.
Construction site with wooden framing, excavator, and workers; hillside setting.
