Who runs the HOA at 21901 Lassen St?

The Assessor's roll doesn't name the homeowners association. California associations file a statement with the Secretary of State listing their address and management contact; search the California Secretary of State's business search for the association's name, or ask the building's front desk or a unit owner for the current property manager. LA Condo HQ is an independent research site, not the association.

I'm a lender or title company. Who completes the condo questionnaire and provides the insurance certificate?

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.

Does 21901 Lassen St need a balcony (SB 326) inspection?

California's SB 326 requires condominium associations to have elevated wood-framed elements such as balconies and walkways inspected on a set schedule. The Assessor's roll does not show whether 21901 Lassen St has completed one. Ask the association for its latest inspection report and reserve study before you buy.
