A verified address is not a qualified lead.

The State of
Address Data:
California

California is the biggest lead market in the country, and the most expensive place to chase the wrong address. We looked at the property behind 32,000 real California address lookups from our national analysis of 500,000. The Golden State runs worse than the national average.

20.2%

of deliverable California addresses are not single-family homes. Nationally it is 18.9%.

01Every California address, by outcome

Barely 2 in 3 California lookups are a home you can sell to.

Every analyzed California lookup lands in one of three places, and the state underperforms the national baseline on both failure modes: more addresses that cannot be confirmed (15.6% vs 13.4% nationally) and more valid addresses that are not single-family homes.

02What California addresses actually are

Condos punch twice their national weight.

California's valid addresses skew away from single-family more than the country as a whole. Manufactured homes are still the largest non-single-family slice (8.1%), and the condo share (5.3%) runs at more than double the national 2.4%, which matters if your offer needs a roof, a yard, or an owner who controls the exterior.

Two thirds of California's single-family leads (65.8%) sit above $500K, and nearly 4 in 10 are $750K+ properties. High-ticket offers have more qualified inventory here than anywhere, and every wasted lead costs correspondingly more.

03Reading this for your team

For lead generation

California leads carry the highest price tags in the country, and 20.2% of the deliverable ones are not single-family homes. At CA acquisition costs, filtering on property type before the dial protects more budget here than in any other state. The 15.6% that cannot be confirmed as valid addresses should never reach a dialer at all.

For home services

Solar, roofing, and remodel tickets in California are priced against $599K median properties, which makes every truck roll to a condo, an apartment, or a manufactured home someone else finances expensive twice over. The condo share alone (5.3%, double the national rate) is a silent qualifier: the owner often does not control the roof you want to sell.

For real estate

With 39.7% of single-family leads valued at $750K+ and a home type on every record, California farm lists can be segmented by value band out of the box. Strip the 15.6% that cannot be confirmed before any door-knock plan and the remaining list is dense with genuinely premium prospects.

Deliverable, not single-family

This report covers 32,000 successful California address lookups made through the AddressVerify API, the California subset of our national State of Address Data analysis of 500,000 lookups. Internal testing traffic is excluded. Only aggregate, non-PII figures are reported. No individual address and no per-customer cut ever leaves the database.

Sample caveat. This is AddressVerify's own customer traffic, which skews toward lead-generation and home-services use cases. Read it as "what California address lists look like," not as statistics on all California mail or housing.

Derivations. California addresses are identified from the state in the normalized address. Deliverability is the API's addressValid flag; home type is the homeType classification. The 15.6% invalid share is addresses that could not be confirmed as a valid residential address; the stored data does not distinguish PO boxes, non-residential buildings, or nonexistent addresses within that bucket, so none is reported. Value figures are computed over the valid California lookups that returned a homeValue.

05For the record
“20.2% of deliverable California addresses are not single-family homes, and the median property behind a California lead is worth $599,472, from an analysis of 32,000 lookups.”
