The number moves on three things: total square footage, how much of the structure and systems you’re touching, and finish tier. For homeowners planning a whole-home remodel Sunnyvale project, here’s what we typically see:
That range holds up across most Sunnyvale neighborhoods, but a full house remodel Sunnyvale CA homeowners actually sign off on depends on your specific layout and systems. We measure the property in person and hand you a line-item fixed price — not a phone estimate that grows once demo starts.
Most Sunnyvale whole-home remodels run 6–10 months from first call to final walkthrough:
Eichler and mid-century whole-home projects sit toward the longer end, since structural framing, slab work, and a full Title 24 retrofit all take more time to do correctly the first time.
Yes, in almost every case. A whole-home remodel touches structural, electrical, plumbing, and HVAC systems, and the City of Sunnyvale Building Division requires permits for all of it. Because Sunnyvale is an incorporated city, its own Building Division issues the permits — not Santa Clara County directly, which only covers unincorporated pockets outside city limits.
Whole-home projects also trigger California’s Title 24 energy compliance standards once a defined share of the building envelope, HVAC, or water heating is altered. We prepare the required CF1R compliance documentation, pull every permit through Sunnyvale’s One-Stop Permit Center, and schedule the structural, rough-electrical, rough-plumbing, and final inspections — so you never make the trip to the counter yourself.
Sunnyvale has one of the largest concentrations of Eichler homes in the country, and a whole-house Eichler renovation is a different job than a single-room remodel. Every system in the house — roof, radiant slab heat, single-pane glazing, and often the electrical panel — usually needs attention at once, not just the room you started with.
To remodel an Eichler or mid-century home in Sunnyvale CA the right way, we start by mapping which posts and beams are load-bearing before any wall comes down, then plan structural headers around that map instead of guessing mid-demo. Radiant slab lines get located and protected before any new plumbing or electrical routes go in. Where Title 24 requires new glazing or insulation, we match window sightlines to the home’s original post-and-beam grid so the compliance upgrade doesn’t fight the architecture. We’ve carried this approach through whole-home projects in Sunnyvale’s Fairbrae, Cherry Chase, Fairwood, Rancho Verde, and Fairorchard tracts.
Whole-home remodels combine several projects into one, so ROI depends on which systems and rooms you touch. According to the National Association of Realtors’ Remodeling Impact Report, kitchen upgrades and new roofing consistently score among the highest “Joy Scores” homeowners report after a project, while cost recovery varies more than satisfaction does.
Based on completed Sunnyvale-area projects, CRBA clients typically recoup roughly 60–80% of a whole-home remodel’s cost at resale, with a 30–40% rental-income premium when the scope includes an ADU or accessory unit. With Sunnyvale’s median home value sitting well above $1.8 million, a well-scoped whole-home remodel usually outperforms a move-up sale in this market — but we’ll tell you honestly which scope actually pays back, not just sell you the biggest job.
The honest answer: whoever gives you a fixed price in writing, pulls every permit in-house, and backs the work with a real warranty — not just the lowest bid. As a home renovation contractor Silicon Valley homeowners have relied on since 2015, CRBA designs, permits, and builds every whole-home remodel with our own in-house crew, so there’s no sub-out chaos and one accountable name — Ray’s — on every permit.

What does a whole-home remodel cost in Sunnyvale?
Cosmetic whole-home refreshes run $150,000–$300,000, full remodels on the same footprint run $300,000–$550,000, remodels with an addition run $550,000–$850,000, and full Eichler or mid-century renovations run $700,000–$1.2M+. We confirm your real number with a free in-home consultation.
How long does a full remodel take?
Most Sunnyvale whole-home remodels run 6–10 months from first call to final walkthrough, including an 8–14 week permit window. Construction itself typically runs 16–28 weeks depending on scope.
Do you handle Santa Clara County permits end-to-end?
Sunnyvale is an incorporated city, so the City of Sunnyvale Building Division issues the permits for most properties — not Santa Clara County directly, which only covers unincorporated areas. We pull every required permit, including Title 24 energy compliance documentation, as part of every contract.
Can you preserve Eichler/mid-century character?
Yes. We map load-bearing posts and beams before demo, protect original radiant slab lines when routing new plumbing and electrical, and match any Title 24-required window or insulation upgrades to the home’s original post-and-beam grid.
How do you approach resale value in this market?
We walk you through which parts of a whole-home scope typically recoup the most at resale — commonly kitchens, baths, and energy upgrades — versus which upgrades are more about your own daily enjoyment of the house. You get an honest read before you commit to the full scope.
