2025-2026 Apartment Security Deposit Interest Rates

The City of San Francisco requires Landlords to pay interest to renters on their security deposits.

San Francisco Security Deposit Interest Rates Remain at 5% for 2025-2026.

For the period from March 1, 2025, to February 28, 2026, the interest rate stands at 5.0%, compared to 5.2% in the previous year. Let's delve into what these numbers mean, how they are determined, and the implications for both landlords and tenants.

Calculation Methodology:

The city of San Francisco, known for its progressive tenant protection laws, follows a specific formula outlined in the Administrative Code, Chapter 49.2. The Rent Board employs the annual average of the 90-day AA Financial Commercial Paper Interest Rate from the immediately preceding calendar year, as published by the Federal Reserve.

For the 2025-2026 period, the rate is set at 5.0%. This is a modest decrease from 5.2% for the period March 1, 2024, through February 28, 2025. Understanding this methodology is crucial for both landlords and tenants to navigate their financial responsibilities and rights.
