How do I find the HOA for a condo in Diamond Bar?

Neither the Assessor's roll nor DRE's list names homeowners associations. California associations file a Statement by Common Interest Development Association (Form SI-CID) with the Secretary of State under Civil Code section 5405, searchable on bizfile Online (bizfileonline.sos.ca.gov). A seller must also provide the association's documents under Civil Code section 4525.
