San Jose Architect — ADU, Restaurant TI, Commercial.
YCD Studio serves San Jose, Santa Clara, Campbell, Milpitas, and the South Bay. ADUs (designed to qualify for San Jose's Express plan check), restaurant and retail tenant improvements, commercial, and custom residential — from feasibility and entitlement through permitting and construction administration.
Why YCD in San Jose
The Bay Area's biggest city — and its fastest ADU path.
San Jose is the largest city in the Bay Area and the most permit-efficient for residential and ADU work, with an Express ADU program and pre-reviewed plan library that clears complete applications in weeks. The upside is real speed; the requirement is a complete, code-correct submittal. Our practice is built to deliver exactly that — feasibility done before you commit, permit-ready drawings on schedule, and agency coordination handled by our team.
San Jose spans the full project spectrum — the residential and ADU demand of California's largest ADU market, the restaurant and retail energy of Santana Row, Downtown, and Willow Glen, and the commercial scale of North San Jose's tech corridor and the Diridon/BART growth area. We work across all of it, plus the surrounding South Bay cities. The thread connecting the practice: we treat the entitlement and permit phase as its own deliverable with its own timeline, so construction starts on schedule — and in San Jose, that schedule can be genuinely fast.
What we do in San Jose
Four practice areas across the South Bay.
ADU and residential demand is the largest single driver here, but restaurant, retail, and commercial TI all see active pipeline. We serve them with the same team.
ADUs & Residential
Custom ADUs, garage conversions, and residential design across San Jose, Willow Glen, Cambrian, Almaden, and Berryessa. San Jose runs an Express ADU program with pre-reviewed standard plans and one of the fastest plan-check turnarounds in California — we design to qualify for it where the lot allows, and prepare full custom sets where it doesn't. California state ADU program coordination, impact-fee analysis, and detached new-build ADUs on South Bay lots.

Restaurant & Cafe TI
Restaurant and cafe tenant improvements across Downtown San Jose, Santana Row, Willow Glen's Lincoln Avenue, Japantown, and the San Pedro Square area. Kitchen design, Type I hood coordination, grease interceptor sizing, ABC licensing, and Santa Clara County Environmental Health plan review — coordinated with San Jose's Building Division and, on change-of-use projects, Planning.

Retail, Office & Commercial TI
Commercial tenant improvements across San Jose's office and retail corridors — Downtown, North San Jose tech campuses, Westfield Valley Fair and Oakridge retail, and the Berryessa/Milpitas BART-adjacent growth areas. Office buildouts, retail fitouts, medical office, and change-of-use analysis when spaces convert between tenant types.

Adaptive Reuse & Mixed-Use
Adaptive reuse and mixed-use work tied to San Jose's downtown growth — converting older commercial stock to restaurant, retail, or residential, and mixed-use infill near Diridon Station and the BART extension. Change-of-occupancy analysis under CBC Chapter 3, seismic and accessibility triggers, and the permitting strategy that keeps a conversion in scope.

Our approach
Design to the fast path — then deliver it complete.
On ADU and residential work, we screen the lot against San Jose's Express and pre-approved-plan eligibility before drawing, so you capture the fast timeline where it's available. On commercial and TI work, we run lease-stage feasibility — building conditions, code path, permit timeline, GC pre-pricing — before construction documents. Either way, the goal is a complete submittal that clears review in one cycle, not three.
