Remodeling Company in Sunnyvale, CA
Home remodeling in Sunnyvale runs between $9,000 for a small bathroom refresh and $130,000 for a major whole-home addition, with most kitchen and full-bath projects landing in the $14,000 – $45,000 range. We handle everything from opening up a 1960s ranch floor plan to adding square footage within the tight R-1 zoning envelope that governs most of the city’s postwar neighborhoods. Our crews work with Sunnyvale’s specific conditions every day: slab-on-grade foundations, original load-bearing walls that complicate open-concept plans, and a building department that scrutinizes seismic shear-wall details under California’s Zone D requirements.

Why Sunnyvale Homes Are Different
Sunnyvale’s residential lots, mostly 6,000 – 8,000 square foot ranches built in the 1950s and 1960s for Lockheed Missiles & Space workers, now carry land values of $1.5 – 2 million or more. That math has reshaped the local construction market toward complete teardown-and-rebuild projects and maximum-footprint new builds rather than conventional remodels. Contractors here must master Sunnyvale’s specific R-0 and R-1 zoning envelopes, its ADU ordinance, and the active El Camino Real densification corridor to stay competitive, skills that differ meaningfully from neighboring Santa Clara or Mountain View’s code environments.
The housing stock itself creates the technical challenges. Postwar ranch-style tract homes with slab-on-grade foundations and original single-pane windows are the norm. Load-bearing walls complicate open-plan remodels because many of these homes were never engineered for the spans homeowners now expect. The city’s flat terrain sits atop expansive bay-margin clays, and Sunnyvale’s building department is known among local GCs for requiring a geotechnical soils report on virtually any project involving a new foundation or significant addition, even on small residential lots. Neighboring cities with hillside or alluvial soil profiles handle this differently. Add the compressed November – March rainy season and full seismic Zone D requirements, and every foundation, shear wall, and anchor bolt spec faces heavy scrutiny during plan check.
Styles & brands we work with
Our Main Sunnyvale Services
Most Sunnyvale homeowners who call us start with one of these three projects:
General Contractor in Sunnyvale
We coordinate full-scope projects from permit to final inspection, working with Sunnyvale’s building department on the soils reports and seismic details that slow down less prepared crews. Our background-checked, uniformed technicians handle everything from shear-wall engineering to the final walk-through, with a written price before any work starts and a photo of the clean-up before the crew leaves. We pull permits, schedule inspections, and make sure the work passes Sunnyvale’s specific plan-check scrutiny the first time. General Contractor in Sunnyvale
Bathroom Remodeling in Sunnyvale
Sunnyvale’s original bathrooms, often 5×8 feet with cast-iron tubs and single sinks, get rebuilt with walk-in showers, double vanities, and waterproofing that meets current code. We work with the slab-on-grade plumbing constraints common in postwar ranches, and we source fixtures from Kohler, Moen, and Grohe with manufacturer warranties you can verify. Shoe covers and drop cloths on every visit, quiet tools during family rest hours where possible, and pet-safe product choices where available. Bathroom Remodeling in Sunnyvale
Kitchen Remodeling in Sunnyvale
Opening up a 1960s ranch kitchen means dealing with load-bearing walls and the low ceilings typical of the era. We engineer the beam spans, handle the permit drawings, and install cabinets from KraftMaid and Wellborn, countertops from Cambria and Silestone, and backsplashes with Schluter waterproofing systems. Every project gets the Cedarwell Care Promise: ask before we move anything, respect the family’s time and quiet hours, explain the price before the work. Kitchen Remodeling in Sunnyvale

Home Remodeling in Sunnyvale
Home remodeling in Sunnyvale means working within the constraints of high land values, strict zoning, and a building department that knows its seismic and soils requirements inside and out. Most of our Sunnyvale clients are not looking to flip a property; they’re raising families in neighborhoods like Birdland or Cherry Chase and need the house to function better without the disruption of moving. We specialize in staying-in-place remodels: kitchen and bath updates, adding square footage through permitted additions or ADUs, and reconfiguring the chopped-up floor plans common to 1950s – 60s ranches. Our Home Remodeling process starts with a written price before any work starts, and every completed project carries the 365-Day Done Right Promise.

Signs you need it
Your home still has the original floor plan from 1962, with small bedrooms, a closed-off kitchen, and one bathroom for a family of four or more.

A whole house remodel in Sunnyvale typically runs from the upper end of multiple room updates combined, with major structural work and additions pushing toward the $45,000 – $130,000 range for home additions and full reconfigurations.
How we do it
We start with a structural assessment of load-bearing walls, engineer the open spans, pull permits with Sunnyvale’s plan check including seismic shear-wall details, then sequence the work room by room so your family can live in the house during construction where possible.
Home Renovation
Signs you need it
The finishes are dated but the layout works, with original cabinets, worn flooring, and fixtures from the 1970s or 1980s that still function but depress the daily experience of the house.

Surface-level home renovations in Sunnyvale typically start around $9,000 for a small bathroom refresh and run to $45,000 for a full kitchen remodel with cabinet, countertop, and appliance replacement.

FAQs About Remodeling Company in Sunnyvale
Yes, we prepare the full documentation package that Sunnyvale HOAs and design review boards require, including material samples, elevation drawings, and color boards. We have worked with the review processes in neighborhoods like Cherry Chase and Birdland where architectural committees review exterior changes, and we build that timeline into your project schedule from day one.
Sunnyvale’s ADU ordinance allows detached and attached accessory dwelling units on most single-family lots, with specific setback, height, and parking requirements that differ from standard home additions. We evaluate your lot’s R-1 zoning envelope, the location of existing structures, and whether a garage conversion or new detached unit makes more sense for your goals and budget, then handle the permit drawings including any required soils reports.
We coordinate the soils report directly with a licensed geotechnical engineer familiar with Sunnyvale’s bay-margin clay conditions, and we build that cost into your written price upfront. The report becomes part of your permit submittal to Sunnyvale’s building department, and it guides our foundation and drainage specifications so the work passes inspection without costly mid-project changes.

What Sunnyvale Customers Say
"Opened up our kitchen. They controlled the dust better than I thought possible, protected the floors, and left a photo of the cleaned space each day. Gentle on the house and on budget."
- Simon Albright"Kitchen remodel. With two kids at home I was dreading the dust, but they walled off the space in plastic and cleaned every single day. Respectful, calm crew. The kitchen is stunning."
- Beverly Austin"Main bath gut and redo. They protected the carpet the whole way down the hall and vacuumed daily. Quiet during naps when they could be. Lovely finish."
- Franklin Mbeki
