What this means for your life
Typical rent runs $3,001 a month in San Diego versus $3,604 in San Francisco, so San Diego is 17% cheaper. A meaningful but not dramatic gap. Factor it into your budget alongside salary differences between the two markets. Over a year the spread is about $7,236, enough to notice in savings, not enough to ignore schools, safety, or pay. San Diego still wins on housing cost; just do not let a 10–20% rent edge override a job that only exists in San Francisco.
