Drawn to glass walls, warm wood, and an indoor–outdoor flow that feels timeless? If you are eyeing an Eichler in Sunnyvale, you are looking at a distinct slice of California modern design. The right home can deliver incredible light and an airy layout, but these mid‑century properties also come with unique systems and maintenance needs. In this guide, you will learn how to recognize signature Eichler features, how to tour and inspect with confidence, and how to plan upgrades that respect the style. Let’s dive in.
What makes an Eichler an Eichler
Eichlers are a specific subset of mid‑century modern homes created by Joseph Eichler’s company from roughly 1949 to 1974, with about 11,000 built in California. Many are found across the Bay Area, and Sunnyvale includes multiple neighborhoods with Eichler designs. These homes remain popular for their open plans and strong indoor–outdoor connection.
Signature design features
Post-and-beam structure
- Exposed posts and beams support the roof, which reduces interior load walls and allows open, flexible layouts. This framing affects how you approach remodels and seismic or structural upgrades.
Slab-on-grade foundation
- Most Eichlers sit on a concrete slab, which houses in‑slab plumbing and influences repair access and cost. You will want to check for signs of slab leaks or past cutouts.
Glass walls, sliders, and clerestories
- Floor-to-ceiling glass and clerestory windows bring in abundant light and connect living spaces to patios and yards. Many originals are single‑pane aluminum, which can affect energy performance and comfort.
Central atrium
- Many floor plans include a private, open-air atrium. It is a defining feature, but it also requires careful attention to drainage, waterproofing, and insect control.
Low-slope rooflines
- Low or nearly flat roofs keep the profile clean and modern. Membrane or built‑up roofs look sleek but need sound drainage and well‑maintained flashings to avoid leaks.
Radiant in‑slab heat
- Original heating is typically hydronic radiant tubing embedded in the slab. Boilers and pumps are often located in the garage or a utility closet.
Honest finishes
- Plywood paneling, tongue‑and‑groove ceilings, exposed beams, and integrated cabinetry define the look. Exterior materials often include redwood or plywood siding and concrete patios that require periodic upkeep.

Why Eichlers resonate in Sunnyvale
Sunnyvale sits in the heart of Silicon Valley, where many buyers value design, light, and flexible spaces that support modern living. The Eichler aesthetic delivers exactly that: open-plan rooms, strong sightlines, and private outdoor areas integrated into everyday life. Because these homes are decades old, smart buyers balance preservation of character with upgrades for safety, comfort, and code compliance.
Touring checklist for Sunnyvale Eichlers
Use this quick guide on your first visit. It helps you spot signature elements and flag areas for deeper inspection later.
Exterior and roof
- Identify the roof type, look for patches, and check gutters, downspouts, and drainage.
- Walk the perimeter to confirm grading directs water away from the slab.
Layout and atrium
- Confirm the open plan, sightlines, and presence of a central atrium.
- Look for planter conditions, staining near atrium walls, and signs of standing water.
Windows and doors
- Operate sliders and large glass panels. Listen for grinding and note sticking or gaps.
- Look closely at sills and thresholds for signs of water intrusion.
Floors and heating
- Walk every room and note unevenness, soft spots, cracked tiles, or persistent cold spots.
- Ask whether the radiant system works and where the boiler and manifolds are located.
Garage and mechanicals
- Inspect the boiler, water heater, and electrical panel for age, corrosion, and upgrades.
- Confirm water heater seismic strapping.
Attic and roof access
- Some Eichlers have limited attic space. From below, look for ceiling stains that suggest leaks.
Outdoor drainage
- Check downspout discharge points and atrium drainage pathways. Confirm water routes away from the structure.
Inspection game plan and specialists
Go into inspections with a plan and the right pros. These homes reward careful due diligence.
Documents to request
- Permit history from the City of Sunnyvale.
- Seller disclosures, any past termite/WDO reports, and records of roof or slab repairs.
- Service records for the boiler, hydronic components, HVAC, and water heater.
Recommended inspections
- Full home inspection with emphasis on roof, structure, and hydronic heating.
- WDO inspection focused on wood decay and termites.
- Plumbing evaluation for in‑slab systems if there are leak signs; consider a sewer lateral camera scope.
- Electrical review by a licensed electrician familiar with mid‑century systems.
- Roofing specialist for low‑slope membrane assessment.
- Structural engineer if you plan layout changes or significant upgrades to post‑and‑beam systems.
- Environmental testing for lead-based paint and potential asbestos before renovation.
Key questions to ask
- Is the radiant heating fully operational, and what are the boiler and manifold ages?
- Any known slab leaks or cutouts? Are repair records available?
- How old is the roof, and were flashings and drip edges installed correctly?
- Is there evidence of termite damage or treatments?
- Were any additions, kitchen/bath updates, or carport enclosures permitted and finaled?
- Has the electrical service been upgraded? Any aluminum wiring present?
- Have windows or doors been replaced, and were the replacements compatible with the Eichler look?
Typical systems and issues to watch
Understanding common issues helps you budget and plan upgrades without surprises.
Roofs and drainage
Low‑slope roofs can leak if membranes age or drainage is poor. Inspect flashings, skylight seals, and scuppers, and look for ceiling stains or wet insulation.
Radiant heat and boilers
In‑slab tubing can leak and is hard to access. Verify operation, check boiler age and service records, and look for dampness or cold areas that hint at slab issues.
Electrical capacity and safety
Older panels and two‑prong outlets are common. Confirm service size, grounding, and GFCI/AFCI protection where required, and have a licensed electrician evaluate any aluminum wiring.
Plumbing and sewer laterals
In‑slab supply or waste lines can complicate repairs. Check for leak signs, water pressure, and water heater age and strapping, and consider a sewer lateral scope.
Windows, doors, and glazing
Original single‑pane aluminum units are part of the look but are less efficient. Test operation and seals, and inspect nearby wood for moisture or termite damage.
Wood decay and termites
Wood siding, posts, and beam connections near grade are vulnerable. A WDO report helps identify decay and insect activity early.
Atrium and landscaping
Planters and irrigation can trap moisture against wood. Verify drainage pathways and waterproofing at planters to protect adjacent structures.
Permits and alterations
Many Eichlers have been modified over time. Verify permit history through the Sunnyvale Planning & Building Division and confirm that major work passed final inspection.
Environmental considerations
Because of the era of construction, lead-based paint and asbestos may be present in some materials. Plan testing before demolition or significant renovation.
Preserve the look, upgrade smart
You can keep the mid‑century character while improving comfort and safety. Plan upgrades with both aesthetics and performance in mind.
Glazing decisions
- Replacing single‑pane units with insulated glazing improves comfort and energy use, though it may change profiles. Consider slim double‑glazed retrofits or interior storm solutions to preserve frames and sightlines.
Heating strategy
- Many owners keep radiant heat by updating boilers and pumps. If in‑slab tubing is at end of life, options include selective slab repairs, in‑ceiling radiant, or adding a separate forced‑air system for cooling.
Electrical modernization
- Upgrading panels, grounding, and adding AFCI/GFCI protection supports today’s loads and safety standards. This is a common and worthwhile improvement.
Roof refresh
- Newer low‑slope membranes such as TPO, EPDM, or updated built‑up systems can reduce leak risk while maintaining the clean roofline.
Permits, financing, and insurance
- Confirm permit requirements for remodels, re‑roofing, or structural changes with the City of Sunnyvale. Lenders and insurers may require updates to older systems, so verify conditions early in your process.
Community and resources
- Explore technical articles and neighborhood context through the Eichler Network. For parcel and permit records, contact Sunnyvale and Santa Clara County offices.
Smart negotiation and contingencies
With older homes, you can build flexibility into your offer strategy. Consider an inspection contingency that allows for specialist follow‑ups on roof, hydronic heating, electrical, and plumbing. You can also request seller repairs for significant defects or use escrow holdbacks, and document permit closure for past work before you remove contingencies.
