Remodeling Company in Sunnyvale, CA
Home renovation in Sunnyvale usually means taking on a 1950s or 1960s ranch and turning it into something that works for how people live now, whether that’s a second-story addition, a full kitchen and bath overhaul, or a detached ADU in the backyard. San Bernardino Contractors handles the entire scope, from the roof down to the pavers, so you’re not juggling a roofer, a cabinet shop, and a tile crew. We’ve served Sunnyvale since 2015, and we know the permit realities, lot constraints, and aging plumbing and wiring that come with homes in 94086, 94087, and the rest of the city. Call (855) 473-5620 to talk through your project.
Why Sunnyvale Homes Are Different
Sunnyvale sits at the heart of Silicon Valley, so construction here is dominated not by greenfield subdivision work but by tear-down-and-rebuild and second-story additions on mid-century ranch lots, driven by tech-wealth homeowners and ADU mandates. The city’s aggressive Housing Element push, state-mandated ADU and multi-family allowances, plus downtown precise-plan redevelopment near Murphy Avenue, means contractors juggle fast-tracked ADU permits alongside older 1950s and 60s tract remodels. That regulatory and lot-value environment is unlike neighboring San Jose or Mountain View, and it changes how a remodel gets priced and permitted.
Much of Sunnyvale’s housing stock is post-WWII single-story ranch and Eichler-era tract homes on small lots in 94086 and 94087, now heavily targeted for whole-home remodels, second-story additions, and detached ADUs. Those original homes often carry aging galvanized or early copper plumbing and knob-and-tube-era wiring that surfaces during any major remodel, so a straightforward kitchen job can turn into a panel upgrade and re-pipe once walls open up. Sunnyvale’s mild Mediterranean climate means year-round exterior work is feasible, but winter rains concentrate roof, drainage, and foundation waterproofing issues, and the region’s seismic exposure near the San Andreas and Hayward faults makes shear-wall upgrades and seismic retrofits standard scope on older homes. The small mid-century lots in 94087 also mean an ADU or second-story addition often triggers setback, floor-area-ratio, and neighbor-privacy review that a contractor can’t assume from a neighboring city’s rules. Sunnyvale’s own ADU ordinance and single-story overlay zones decide what actually gets permitted, and we plan around those from day one.
Styles & brands we work with
Our Main Sunnyvale Services
Most Sunnyvale homeowners call us for two things: a full general-contractor relationship to run a whole-home project, or a targeted home remodel like a kitchen, bathroom, or addition. Both routes get the same single-point accountability and the same access to our 50-plus brand relationships.
General Contractor in Sunnyvale
As a General Contractor in Sunnyvale, we run the entire job: permits, sequencing, material procurement, and every trade from foundation to finish. On a Sunnyvale ranch, that often means coordinating a seismic shear-wall upgrade, re-piping, and a second-story addition in one permit set rather than three separate bids. You pick the brand, we handle the build, and there’s no subcontractor shuffle because one team owns the schedule. That matters when your 1950s tract home reveals knob-and-tube wiring mid-demolition and someone has to make a call fast without stalling the job. Our scope covers roofing, windows, siding, kitchens, baths, hardscaping, and ADUs, so the same crew that frames the addition can set the Cambria countertops and hang the Therma-Tru door.
Home Remodeling in Sunnyvale
For a Home Remodeling in Sunnyvale, we usually start with the rooms that add the most daily value: kitchens and bathrooms, then expand to exterior systems like roofing or windows if they’re near end of life. Sunnyvale homes from the 50s and 60s tend to have small, closed-off kitchens and single bathrooms, so the typical job involves reconfiguring walls, upgrading plumbing and electrical, and selecting finishes from our brand roster, Kohler and Grohe fixtures, KraftMaid cabinetry, Silestone or Caesarstone counters. Because those original homes often carry early copper plumbing, we plan for re-pipe scope inside the same permit, which keeps the city approval moving instead of stalling it with a mid-project change order.

Home Renovation in Sunnyvale
Home renovation in Sunnyvale often means bringing a 1950s or 1960s ranch up to current code and current living standards in one coordinated effort, because the original homes carry aging galvanized or early copper plumbing and knob-and-tube-era wiring that surfaces the moment walls open. The mild climate lets us work exteriors year-round, but winter rains push roof, drainage, and foundation waterproofing scope into the same schedule, while the city’s seismic exposure makes shear-wall and retrofit work a standard part of most major permits. San Bernardino Contractors handles all of it through one Home Renovation contract, so the re-pipe, the panel upgrade, the kitchen, and the roof get sequenced by one team instead of four. You choose the finish level, from builder-grade to ultra-premium, because our brand roster spans every tier.
Home Renovation Contractors
Signs you need it
You notice ungrounded two-prong outlets, corroded galvanized supply lines, or a foundation that’s never been bolted for seismic loads, and you want one crew to resolve all of it before a kitchen or addition goes in.
What it costs in Sunnyvale
Whole-home renovation scope varies by square footage and systems, but typical Sunnyvale projects run $45,000 to $130,000 when they include structural, plumbing, electrical, and finish work together.
How we do it
We start with a site walk and permit review against Sunnyvale’s current ADU and single-story overlay rules, then build one schedule that sequences seismic retrofit, rough plumbing and electrical, and finish trades so inspections pass in order and the job never stalls.
Home Renovators
Signs you need it
Your Sunnyvale ranch still has its original footprint, one bath, and a galley kitchen, and you’re planning to stay in the house but need more functional square footage.
What it costs in Sunnyvale
A full-interior renovation of a mid-century Sunnyvale home, including kitchen, bath, systems, and finish work, typically lands between $14,000 and $45,000 for the kitchen and $9,000 to $28,000 per bath, with whole-home scope often reaching $45,000 to $130,000.
How we do it
We remove finishes down to framing, replace the lines and wiring that reveal themselves, reconfigure the floor plan to open the kitchen to the living space, and rebuild using the brands you select from our cabinetry, fixture, and countertop roster.
Home Improvement Contractors
Signs you need it
Your windows fog, the roof is past its useful life, or the siding is original and failing, and you want those systems done before interior finishes get ruined by the next wet winter.
What it costs in Sunnyvale
Home improvement projects in Sunnyvale range widely: roof replacement runs $8,000 to $20,000, window replacement $4,500 to $15,000, and driveway replacement $5,000 to $14,000, depending on material and square footage.
How we do it
We assess the exterior envelope first, then schedule roofing, windows, siding, and hardscape in the order that protects the interior, using GAF or CertainTeed shingles, PGT or CGI windows, and James Hardie siding where appropriate.
Home Renovation Companies
Signs you need it
You’re weighing whether to move or renovate, and the answer hinges on what a full-scope renovation would actually cost and how long it would take on your specific Sunnyvale lot.

As a full-scope home renovation company, we see most Sunnyvale whole-home projects land between $45,000 and $130,000, while a garage conversion runs $30,000 to $80,000 and an ADU construction $90,000 to $220,000.
How we do it
We price the full scope up front with written line-item detail, then run the job as a single contract so the framing, plumbing, tile, and counters all come from one accountable team instead of four separate bids.
Renovation Contractors
Signs you need it
You’ve already started gathering quotes and discovered that different contractors are pricing different scopes, and you need one renovation contractor who can reconcile them into a single plan.

How we do it

What Sunnyvale Customers Say
"The foundation survey came back dead on. Everything downstream of that being square is the reason the rest of the build went smoothly."
— Bethany Delaney"Allowances in the contract were realistic rather than artificially low to make the bid look good."
— Paul Kowalski"He caught an error in the engineer's drawings before it got framed, which would have been an expensive thing to discover later."
— Alejandro Castillo
