I am a member of the State Bar of California, the Bar of the U.S. District Court for the Central District of California (San Luis Obispo, Santa Barbara, Ventura, Los Angeles, Orange, San Bernardino, Riverside Counties), and the California and National Associations of Realtors. Please permit me to assist.
If I understand your facts correctly (and I may not), then it appears that there is currently $15,700 minus $6,000, or $9,700 at issue. That amount would be within the scope of the Los Angeles County Superior Court small claims department. So, you could simply demand that amount of money, payable immediately, or you will file a small claims action to recover that amount. Seems like a pretty easy case.
If there is more than $10,000 at issue, then you need to hire a lawyer to shake the money loose from your HOA. Typically, a letter and a phone call is usually sufficient -- but, sometimes you have to sue.
There is are no government regulatory agency for HOAs in California. It's simply between you and the HOA. So, the options that I've described are the only ones available.
