Commercial & Residential Landscaping
Full-service commercial and residential landscaping — estate gardens, retail grounds, hardscape, and smart irrigation across 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's landscaping division serves both sides of California: estate gardens and outdoor living for residential clients, and grounds programs for retail centers, campuses, and commercial properties — from the Bay Area to Sacramento, and San Francisco to San Diego.
In San Jose and across Santa Clara County, JMG delivers landscaping under California Contractor's License #1007864 — permitted, inspected, and personally overseen by owner Jerry Guinn. Drought-tolerant conversions, smart irrigation, architectural lighting, and hardscape are engineered for beauty and for California's water reality — installed and maintained by the same in-house team.
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.
