Board and Care Costs in San Marcos
In 2026, most board and care homes in San Diego County cost about $5,500 to $9,500 a month. Many San Marcos homes sit in the middle of that range, usually below coastal Carlsbad and Encinitas. Shared rooms sit at the lower end, while private rooms and higher care needs cost more.
Unlike many large communities that add care-level fees on top of rent, board and care homes in San Marcos usually charge one monthly rate that covers care, meals, medication management and laundry.
Most families pay privately, often with savings, a home sale or long-term care insurance. Some residents qualify for help through VA Aid and Attendance, the SSI board and care rate or California’s Medi-Cal Assisted Living Waiver, which has limited spots.
