Who Built My House? How to Find the Builder or Architect of a Silicon Valley Home

Who built your house, and who designed it? In Silicon Valley the answer is often findable, because most neighborhoods went up as tracts by a known builder, and many listings, permits and county maps still carry the name. Here’s where to look, in the order we’d look, and how to check what you find.

The short answer

• Start with the tract. The county’s parcel map and your title documents give the subdivision or tract name and number, and a tract usually had one builder.
• Search old listings. Sellers name a builder when it adds value (“original Eichler”, “Mackay home”, “Stern & Price”). Our Builder Files pages search 20-plus years of listing descriptions for each builder.
• Pull the permit file. The city’s building records can show the original builder, contractor or architect on the permit or plans.
• Read the house. Many builders have a signature: post-and-beam with an atrium, a long low ranch, a particular roofline or window wall.

1. Find the tract name and number

Most Silicon Valley houses built from the 1940s on were built as part of a subdivision, recorded with the county as a tract with a number and often a name. Three places show it:

• The assessor’s parcel map. The Santa Clara County Assessor (sccassessor.org) and the San Mateo County Assessor-County Clerk-Recorder (smcacre.gov) publish parcel maps by parcel number; the map page usually names the tract it was drawn from.
• Your deed or title report. The legal description often reads “Lot 12, Tract No. 1234”, with the tract’s recorded name.
• The recorded tract map. The county recorder keeps the original subdivision maps; the subdivider’s name is on them, and it’s usually the builder or its land company.

With a tract name, search it with the word “builder” or the city name; tract names like Fairgrove, Greenmeadow or Rancho Rinconada lead straight to their builders.

2. Search the listings

When a builder or architect adds value, sellers say so, and those descriptions stay in the MLS record. Our Builder Files do this search for you: each page lists the sales in our area whose listings name that builder, on a map, with price per square foot over time. If your street shows up on a builder’s map, your neighbors’ listings named the builder.

• National builders: KB Home, Brookfield, Pulte Homes, Shea Homes, Lennar, Toll Brothers, Taylor Morrison, D.R. Horton, Tri Pointe Homes, K. Hovnanian and Meritage Homes.

3. Pull the permit and plans

Cities keep building permits, and for many houses the original permit or plans name the builder, the contractor or the architect. Ask the city’s building or permit center how to request records for your address; some cities have online permit lookups for newer records and a records request for older ones. Plans for older houses may be on microfilm, and some cities limit copies of plans, so ask what they can share.

4. Read the house

Builders repeated what sold. A few tells, with the pages that show them:

• Eichler: post-and-beam, flat or low-pitched roofs, walls of glass to the back yard, often an atrium. See Eichler homes and Is it really an Eichler? for the look-alikes.
• Mid-century ranches and modern tracts by other builders: Mackay, Stern & Price, Mardell and others; see the mid-century tract index.
• Older houses: Victorians, Craftsman bungalows and Spanish Revival homes were often built one at a time; the architect, if any, may be named in a city historic resources inventory. See Home Styles.

5. Ask around

• Neighbors and the neighborhood association often know the tract’s story, and some keep the original sales brochures.
• The city’s historic resources inventory or local historical society covers notable architects and older houses.
• A local agent who has sold in the tract can usually tell you in a minute.

Why it matters

• Value: some names sell. Our Builder Files show price per square foot for each builder’s sales over time.
• Remodeling: knowing the original design helps you keep what buyers pay for; see remodeling an Eichler.
• Rules: some tracts have design guidelines or single-story overlays; see overlays by city.
