CGI Construction in Cupertino, CA | Rowan Construction Group Santa Clara
Independent CGI construction service across Cupertino runs $9,000 for a small bathroom remodel up to $220,000 for a full ADU build, with most CGI kitchen renovations falling between $14,000 and $45,000. What separates our work here is that we prepare the full structural calculations and Title 24 compliance packages Cupertino’s building department expects on first submittal, because incomplete drawings in this city routinely add months, not weeks. Call (669) 259-1843 to schedule your free estimate with a written price before any work starts.
Why Cupertino Residents Choose Us for CGI Service
We’ve worked CGI cabinetry, window systems, and structural hardware across Cupertino’s ranch-home stock since before the current wave of $500K-$1M gut renovations began. The homeowners here, many of them Apple engineers and Silicon Valley technical professionals, do not want enthusiasm. They want the spec sheet, the load calculation, and the permit status in writing.
Grant Rowan, our owner, trained in construction technology at Los Angeles Trade-Technical College, spending years learning to read structural drawings and calculate load paths. He grew up in Beverly Hills watching older homes get rebuilt badly, which left him with a low tolerance for shortcuts that show up as cracks five winters later. That background matters in Cupertino, where the clay soils shift measurably between seasons and the building department reviewers will catch an incomplete submittal before breakfast.
We source CGI sales & service parts, OEM-spec hinges, glides, and connectors where the line is still active, and we stock high-grade aftermarket equivalents for discontinued CGI components so a Cupertino job does not stall waiting on a back-ordered hinge plate. Our crews are background-checked and uniformed; a live person answers calls 24/7; and every visit produces a documented photo record, included as standard, not sold as an upgrade.
Under Clause 1 of The Haven Standard, the price is written before anyone picks up a tool. Under the 365-Day Done Right Promise, if it is not done right, we make it right, backed by a terms page, not a handshake.
Common CGI Construction Problems We Solve in Cupertino

- Hinge plate and drawer glide failure in original CGI cabinets. The 1960s-1970s ranch homes that dominate Cupertino have wall framing racked out of plumb by decades of clay-soil movement. CGI cabinet doors that once closed square now sag or bind. We replace the OEM or OEM-spec hinge plates and realign the boxes to the actual wall, not to a level line that ignores the structure.
- Sticking windows and failed seals in Monta Vista foothill homes. CGI exterior door and window systems specified for Title 24 compliance develop operational problems when seasonal clay expansion shifts headers and wall openings. We diagnose whether the fix is gasket replacement, header reinforcement, or full re-framing of the opening.
- Plumbing integration failures during “cosmetic” remodels. Original Cupertino ranch homes commonly have galvanized supply lines nearing end of life. A homeowner opens walls for CGI cabinet replacement and finds the plumbing behind them is the real project. We flag this during estimate, not demolition, and price the full scope in writing.
- Cabinet misalignment over shifting post-and-pier or slab foundations. CGI cabinet boxes installed on original 1955-1980 subfloors show toe-kick cracks and door gaps after wet-season soil movement. We assess whether the fix is cabinet shim and re-anchor, or whether the foundation needs engineered stabilization first.
- Structural connector hardware fatigue in addition and ADU framing. CGI framing and structural connector hardware for additions and ADUs must accommodate Cupertino’s seismic requirements near the Monta Vista fault systems. We engineer for the actual loads, not the code minimum, because the city’s reviewers will check the math.

AfterCGI Service in Cupertino: What Local Conditions Mean for Your Equipment
Cupertino sits where the Santa Clara Valley floor meets the Santa Cruz Mountains foothills, and the expansive clay soils throughout the city swell in winter rains and shrink in summer dryness. That movement is not abstract geology. It is the reason a CGI kitchen cabinet door that closed in October binds in March. It is why a window header that was level in the dry season shows a gap after the first heavy rain. And it is why any contractor working CGI products in Cupertino who does not account for soil movement in the structural design is building a callback into the job.
The other local factor is the homeowner base itself. Cupertino’s residents, disproportionately engineers and technical professionals, routinely scrutinize structural drawings and material specs at a level we rarely see elsewhere. The city’s building department plan-check process reflects this. Submitted drawings must include full structural calculations and Title 24 energy compliance packages, because incomplete submittals get rejected, and a rejection cycle in Cupertino typically adds eight to twelve weeks. We prepare every CGI kitchen, addition, and ADU permit package for first-pass approval. The alternative is a timeline that extends into the next school year, and in a district where families bought specifically for Cupertino Union or Fremont Union access, that delay is not acceptable.
On a 1968 ranch home off Bubb Road near Monta Vista High, our crew opened a CGI kitchen wall for an open-plan remodel and found the original post-and-pier foundation had shifted with the clay soil, so the 12-foot header needed an engineered replacement and new footings before any CGI cabinets could be hung plumb. We submitted the revised structural calcs and Title 24 package in the first plan-check round, passed without a correction cycle, and delivered our Kitchen Remodeling in Cupertino with CGI maple cabinetry, quartz counters, and a new island on schedule. Measure twice, document once, and never assume the last contractor left things square.
CGI Models & Products We Service in Cupertino

We work with CGI kitchen cabinetry lines in maple, cherry, and painted finishes and offer our Bathroom Remodeling in Cupertino, including the semi-custom cabinet series commonly found in 1960s-1970s Cupertino ranch kitchens. Our scope covers CGI exterior door and window systems specified for Title 24 compliance, and CGI framing and structural connector hardware for additions and ADUs.
Parts strategy is straightforward. We source CGI-compatible OEM-spec hinges, glides, connectors, and gaskets where the original line is still manufactured. When OEM parts are discontinued or lead times would stall a permitted Cupertino job, we use high-grade aftermarket equivalents and document the substitution in the written scope. We tell homeowners plainly when a CGI component can be repaired versus when full replacement is the smarter structural and financial move. No work proceeds on a change until the change order is signed. That discipline, the administrative rigor Haven acquired Rowan for, is why our projects finish within a few percent of the agreed price.

What drives cost: the condition of the existing substrate, whether structural engineering is required for clay-soil stabilization or seismic compliance, and the completeness of the first permit submittal. A job that passes plan-check on round one costs less than one that cycles through corrections. Our estimates are free, line-itemed, and delivered in writing before any work starts.

FAQs - CGI Construction in Cupertino
Yes, if the remodel involves removing or altering load-bearing walls, which is common in open-plan conversions of 1960s-1970s ranch homes. The original post-and-pier or slab foundations in Cupertino have often shifted with clay-soil movement, so a structural engineer must verify that headers and footings can handle the new configuration before CGI cabinets are hung. Call (669) 259-1843 and we’ll assess whether your wall is load-bearing during the free estimate.
We can match CGI maple, cherry, and painted finishes where the line is still active, sourcing OEM-spec doors, drawer fronts, and hinge plates. If the original CGI series is discontinued, we use high-grade aftermarket equivalents that match the existing box dimensions and finish profile, documented in the written scope. Call (669) 259-1843 for a free assessment of what can be matched versus what needs full replacement.
Title 24 energy compliance is mandatory for all permitted additions and ADUs in Cupertino, and the city’s reviewers verify the calculations against the structural drawings. CGI window and door systems must meet the specified U-factor and SHGC ratings, and the insulation and HVAC sizing must be modeled in the compliance software. We include the full Title 24 package in our first submittal to avoid the correction-cycle delays that are common in Cupertino. Call (669) 259-1843 to review how Title 24 affects your specific CGI addition.
Most 1955-1980 ranch homes in Cupertino have post-and-pier or slab foundations not originally engineered for second-story loads. A soils report and engineered foundation upgrade, often including new footings and stem walls, are standard requirements before CGI framing and structural connectors are installed. The clay soils shift seasonally, so the engineered design must account for active soil pressure, not just static loads. Call (669) 259-1843 for a foundation assessment as part of your free estimate.
Yes. We prepare and submit the full permit package, including structural calculations and Title 24 energy compliance, for first-pass approval. Cupertino’s building department is notably rigorous, and incomplete submittals from contractors who treat the city like a neighboring jurisdiction routinely add months. Our documentation discipline, the same that has kept 4,000-plus projects within a few percent of estimate, applies equally to the permit phase. Call (669) 259-1843 to discuss your CGI remodel timeline.
