1. What is the Rent Increase Formula?

The City of Los Angeles rent control ordinance limits annual rent increases to the lesser of CPI + 3% or 8%. This calculator helps determine the maximum allowable rent increase for 2025 under these regulations.

2. How Does the Calculator Work?

The calculator uses the LA rent control formula:

Where:

• \( CPI \) — Consumer Price Index percentage (annual change)
• \( Current\ Rent \) — The current monthly rent amount
• \( 3\% \) — The fixed percentage added to CPI
• \( 8\% \) — The maximum allowable increase cap

Explanation: The formula ensures landlords cannot raise rents more than 8% annually, even if CPI+3% would be higher.

3. Understanding LA Rent Control

Details: Los Angeles rent control applies to most multi-unit buildings built before October 1978. The ordinance limits rent increases to protect tenants from excessive hikes while allowing landlords reasonable adjustments.

4. Using the Calculator

Tips: Enter the current CPI percentage (available from government sources) and your current monthly rent. The calculator will show your maximum allowable rent increase and new rent amount.
