California HOAs

36,801 associations govern 2,469,060 California homes

Every association files a statement with the Secretary of State saying what kind of development it manages, how large it is and where it is. This is that register, county by county, with each association’s election requirements worked out for its size.

Register as of 2026-10-03 Source Secretary of State, CPRA response Filed under Civ. Code § 5405
Map of California in which every home in a homeowners association is a grain of ink: dense along the coast from the Bay Area to San Diego and around Sacramento, sparse in the Central Valley and the mountains.
One grain, one home. 1,924,089 homes drawn round the cross streets their association filed; 506,996 more are counted but could not be placed. The register keeps three digits of a count, so the largest are drawn smaller than they are. How the map filled in, decade by decade →

What the register leaves out

Questions this register answers

How many HOAs are there in California?
As of 2026-10-03, the Secretary of State’s register lists 36,801 active associations that have filed the statement Civil Code § 5405 requires, governing 2,469,060 homes. Another 5,862 active corporations registered as common interest developments have filed no § 5405 data.
Which California county has the most HOAs?
Los Angeles County has 10,108 associations governing 399,311 homes; San Diego County has 4,856 associations governing 353,438 homes; Orange County has 3,658 associations governing 369,855 homes, as of 2026-10-03.
How large is a typical California HOA?
Half govern 26 homes or fewer. 24,035 govern 50 or fewer, and 512 govern more than 500. 62% are condominiums and 37% planned developments.
How do I find which HOA governs a property?
Search this register by the association’s name or by the two streets of its location. The register lists associations, not the homes in them, and gives no city for a development; the property’s governing documents name its association.
Where does this information come from?
From the statements associations file with the California Secretary of State under Civil Code § 5405, obtained by a California Public Records Act request; the register was copied on 2026-10-03. The president’s contact details are withheld by § 5405(f), and this site names no other person either.
