Commercial & Residential Structural Framing
Load-bearing walls, additions, and seismic-smart structural framing engineered for California.
Luxury remodels and custom ADUs in one of Silicon Valley's wealthiest family communities — where lot values reward estate-level craftsmanship.
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 Los Altos 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.
Los Altos Community Development guides projects through planning and building review with close attention to lot coverage and neighborhood scale. We remodel the city's classic ranch homes, build ADUs that respect its single-story streetscapes, and deliver downtown-adjacent commercial work without disrupting neighboring businesses.
