MAAC's administrative headquarters on Chula Vista's Third Avenue has anchored the South Bay social-services ecosystem since the organization's founding in 1965 as the Metropolitan Area Advisory Committee on Anti-Poverty of San Diego County. Operating under EIN 95-2457354 with more than 400 employees across 30-plus program sites countywide, the Third Avenue Village hub coordinates health-access partnerships with providers including Community Health Group. MAAC's portfolio encompasses Head Start child development for birth-to-five populations, below-market-rate housing management, low-income weatherization, a community charter school, workforce development, and addiction-recovery services. Annual operations support more than 100,000 individuals through economic-mobility pathways, with community programming staged at venues including Heritage Community Center. The housing division alone manages 876 residential units across six properties, with weatherization crews installing carbon-monoxide alarms, heating-source replacements, attic insulation, and low-flow fixtures in qualifying households.
