Condo project at 24238 Sylvan Glen Rd, Diamond Bar

Neither the Los Angeles County Assessor's roll nor the California DRE public-report list names the homeowners association for Condo project at 24238 Sylvan Glen Rd (Tract 43756, Lot 4). California associations file a Statement by Common Interest Development Association (Form SI-CID) with the Secretary of State under Civil Code section 5405; search bizfile Online at bizfileonline.sos.ca.gov, or ask the seller, who must provide the association's documents under Civil Code section 4525. LA Condo HQ is an independent research site, not the association.

The Assessor's 2026 roll records 40 condominium unit parcels on Tract 43756, Lot 4, at 24238 Sylvan Glen Rd and 4 other street addresses, Diamond Bar, CA 91765. That makes it the 34th-largest of the 63 condominium projects with 20 or more units in Diamond Bar.

The Assessor records a year built of 1988 for these units (the roll's YearBuilt field). The roll's per-unit recording dates are each unit's latest deed, not the date the condominium was created, so they are not a guide to the project's age.

California Civil Code section 4525 requires a condominium seller to give the buyer, as soon as practicable before title transfers, the association's governing documents, its budget and reserve disclosures, its financial statement, the unit's assessments and any unpaid amounts, notices of violations and other required disclosures. Under section 4530 the association must provide those documents to the owner within 10 days of a written request, and may charge a fee for its reasonable cost.

The association or its management company — not LA Condo HQ. We are an independent research website with no access to any association's records, so we can't complete condo questionnaires, issue estoppel certificates or supply master insurance policies. Ask the unit owner or the building for the current property manager, or look up the association's registered agent and principal address in the California Secretary of State's business search.
