What this means

Read the deadline, trigger, and penalty together before sending a letter. Match the dates in your documents to the trigger listed above, then cite Cal. Civ. Code §1950.5 and request the deposit amount supported by your records.

Worked example

Use your actual deposit amount when you write the letter. For context, median rent in California is $2,161 according to U.S. Census Bureau American Community Survey (ACS) 1-Year Estimates, via SCAG/USC Sol Price School "American Community Survey 2024 1-Year Estimates" report (October 2025), Table B25064-derived county figures data as of .

  • Los Angeles County: $2,058
  • Orange County: $2,551
  • Riverside County: $2,109
  • San Bernardino County: $2,010
  • Ventura County: $2,376

Example demand basis: a deposit equal to the state median rent starts at $2,161 before applying the state formula: Statutory damages of up to 2x the deposit, in addition to actual damages, when retention is in bad faith (Civ. Code §1950.5(l)).
