Blog > Eichler, ranch or new construction? A Silicon Valley guide
property nerd guide · buyers
Silicon Valley's housing runs from glass-walled Eichlers to postwar ranch homes to brand-new rebuilds. Each style comes with its own upkeep, remodel rules and resale questions. Here's how we help buyers compare them.

the short version
Pick the house, then read the rules that come with it
Two homes on the same street can differ by decades. The style you choose shapes what you'll maintain, what you're allowed to change and who will want the home when you sell.
Mid-century modern and Eichler homes have been a team specialty for years, and we also manage restoration and pre-listing projects, so we see these houses from the crawl space up. Here's what we tell buyers about each style.

three styles
What each style really means
Eichler
Joseph Eichler's tract homes, built from 1949 in Sunnyvale and through the 1950s and 1960s in Palo Alto, Sunnyvale and beyond. Look for post-and-beam frames, walls of glass, atriums and low-pitched or flat roofs. Palo Alto has one of the Bay Area's largest concentrations, in tracts such as Greenmeadow, Fairmeadow and Charleston Meadows. Sunnyvale has Fairbrae and Rancho Verde, and Cupertino has Fairgrove.
Ranch
Single-story postwar homes with simple, practical plans. Cupertino's Rancho Rinconada began in the 1950s with ranch houses designed by Cliff May, and Sunnyvale has many ranch tracts from the 1960s to the 1980s. In Los Altos, the largest share of homes dates from 1940 to 1959, and minimum lot sizes start at 10,000 sq ft.
New construction
Rebuilds on older lots and newer planned neighborhoods. Many original Rancho Rinconada houses have been rebuilt since the mid-1990s, Cupertino's Oak Valley was built around 1999 to 2002, and Los Gatos approved 320 homes in the first phase of North 40 in 2017.
| Style | Maintenance to check | Remodel rules to check | Resale considerations |
|---|---|---|---|
| Eichler | Radiant heat pipes in the slab, low-slope roof, single-pane glass, lead paint in pre-1978 homes | Eichler design guidelines, single-story overlays, historic districts, Cupertino's R1-e zoning | Original details and sensitive updates matter to many Eichler buyers; an overlay limits second stories |
| Ranch | Age of roof, electrical, plumbing and sewer lateral; past additions and their permits | Standard zoning plus any single-story overlay; two-story design review in some cities | Lot size and layout drive interest; buyers often weigh remodel versus rebuild |
| New construction | Finaled permits, drainage and waterproofing, any builder warranty | Fewer near-term projects; HOA rules in planned neighborhoods | Finish level and floor plan compete with other recent builds nearby |
lot size
Lot size follows the city and the tract, not the style
Zoning sets the minimum lot, so check the parcel map rather than assuming. Los Altos single-family zones require at least 10,000, 20,000 or 40,000 sq ft, and neighboring Monte Sereno zones its lots R-1-8, R-1-20 and R-1-44. A recent rebuild may already use most of the floor area the zoning allows, while an original single-story home may leave room to grow, if the overlay, setbacks and design rules permit it.
remodel rules
The local rules that shape Eichler and ranch remodels
Palo Alto
The city adopted voluntary Eichler design guidelines in 2018. In late 2015 the City Council approved single-story overlay zoning for two Midtown Eichler tracts, Los Arboles and Greer Park North, which stops new second stories. Greenmeadow and Green Gables are National Register historic districts. See our Palo Alto guide.
Sunnyvale
Sunnyvale adopted Eichler Design Guidelines in 2009 and publishes a separate guide for Eichler window replacement. Neighbors can apply as a group for single-story overlay zoning; the City Council approved one for the Dartshire-Devonshire Eichler streets in 2016. See our Sunnyvale guide.
Cupertino
Fairgrove is zoned R1-e, and new work there must meet the Eichler building design requirements in the city's R1 ordinance, with an Eichler Design Handbook as a guide. Cupertino's R1-i single-story overlay limits homes to one story and 18 feet. See our Cupertino guide.
Everywhere
State law, including SB 9 and ADU rules, opens options on many single-family lots, but historic status can limit them. Ask the city about any address before you plan an addition.
upkeep
What we check first in a mid-century home
Most Eichlers were heated by hot water running through pipes in the concrete slab. The Eichler Network reports that copper systems can often be repaired, while steel systems that leak from corrosion generally can't, and owners then need another heating solution. Leaks are hard to spot because the water usually drains into the ground.
Eichler roofs are low-slope. They were originally tar-and-gravel over a wood deck with little insulation, and owners now choose among several membrane and foam systems. Ask the roof's age and type, and look for signs of ponding water. For any home built before 1978, expect a federal lead-based paint disclosure, and test for other older materials before demolition.
property nerd note
Schedule the radiant heat pressure test and an Eichler-savvy roof inspection inside your contingency period, not after. Those two reports drive most of the surprise costs in mid-century homes, and they give you real numbers to negotiate with.

faq
Silicon Valley housing styles: FAQ
Can I add a second story to an Eichler?
It depends on the address. Some Eichler neighborhoods in Palo Alto and Sunnyvale have single-story overlay zoning, Cupertino has its own R1-i single-story overlay, and Fairgrove has R1-e Eichler rules. Check with the city before you buy.
Are Palo Alto's Eichler guidelines mandatory?
Palo Alto's guidelines, adopted in 2018, were approved as voluntary guidelines. Overlay zoning and historic district rules are separate and do carry weight, so check all three for any address.
What is radiant heat, and why does it matter?
Many Eichlers were heated by hot water running through pipes in the slab. A specialist can pressure-test the system, and the result can change your plans and your offer.
