Commercial & Residential Structural Framing
Load-bearing walls, additions, and seismic-smart structural framing engineered for California.
Our home base — Silicon Valley's capital, where JMG delivers high-end residential remodels, custom ADUs, and commercial build-outs across every district.
JMG frames room additions, ADU shells, and open-concept structural conversions with engineered lumber, steel, and hold-down systems that satisfy the strictest Bay Area building departments.
In San Jose and across Santa Clara County, JMG delivers framing under California Contractor's License #1007864 — permitted, inspected, and personally overseen by owner Jerry Guinn. Every structural modification is permitted, engineered, and inspected — protecting both your investment and your family's safety in earthquake country.
San Jose projects run through the City's Permit Center and the SJplans online portal — and San Jose's pre-approved ADU plan program can shave weeks off a backyard-unit timeline. From Willow Glen and Cambrian ranch remodels to Almaden Valley estates and downtown tenant improvements, JMG manages submittals, plan-check corrections, and inspections end to end.
