Search Property Records in 91001, Altadena CA

Altadena’s 91001 ZIP code is primarily a residential market, although ZIP boundaries, Census geographies, and assessor-parcel boundaries do not align perfectly, so no single official source publishes a definitive “total property” count or property-type mix for the ZIP alone. The most dependable broad housing benchmark is the U.S. Census Bureau’s 2020 Decennial Census, which counted 15,284 housing units in the Altadena census-designated place; this is a housing-unit count—not a count of taxable parcels, commercial buildings, or individual condominium records. Market pricing is best measured through active local listing and closed-sale databases, but values change monthly and vary by source; therefore, a current median sale price and average price per square foot should be taken from a dated MLS-based source such as Redfin, Realtor.com, or the California Regional Multiple Listing Service rather than treated as a fixed ZIP statistic. Detached single-family houses are clearly the dominant housing form in Altadena, while condominiums, co-ops, and larger multifamily buildings represent a much smaller portion of the housing stock; however, the Census does not classify “co-ops” separately in a manner that supports a reliable 91001-only percentage, and it does not include commercial parcels in housing-type tables. Likewise, a defensible 10-year average annual-sales figure requires access to a complete historical closed-sale dataset for 91001—such as MLS records or county transfer data—and should not be estimated from current listings or broad citywide reports. In short, publicly verifiable data support describing 91001 as a predominantly single-family, low-density residential market with roughly 15,000 housing units in the broader Altadena Census area, but exact ZIP-level totals, commercial-property share, condominium/co-op share, and annual-sale averages require a parcel-level assessor extract or subscription MLS dataset.
