Specialized bookkeeping for homeowner associations, condominiums, and commercial office parks in downtown San Diego is the exclusive focus of HOA Accounting Services, an ECHO and Community Association Institute member firm operating from Broadway. The firm produces monthly and annual financial statements, manages assessment billing and accounts receivable, and coordinates annual CPA review processes—financial controls that integrate with commercial property coverage programs administered by agencies like Cavignac in the same district. HOA Accounting Services operates across eight states including California, Colorado, Oregon, Washington, Texas, Nevada, Utah, and Arizona, maintaining compliance with each jurisdiction's statutory requirements for common-interest development financial reporting. The firm's segregation-of-controls model separates accounting functions from property management operations, giving boards independent oversight of assessment collection, vendor payments, and reserve fund tracking. This independent structure serves both self-managed associations and those contracted with full-service management firms, including Bankers Hill property brokerages like Barnett Properties that manage condominium portfolios requiring separate financial reporting. Highest-complexity engagements involve multi-phase master association accounting with subordinate sub-associations, reserve study reconciliation across shared infrastructure, and forensic reconstruction of delinquent assessment histories for lien-priority litigation support.
