1. What is California Rent Control?

California rent control laws limit how much landlords can increase rent each year for qualified properties. The maximum increase is typically based on a percentage of the Consumer Price Index (CPI) plus an additional fixed amount allowed by local ordinances.

2. How Does the Calculator Work?

The calculator uses the California rent control formula:

Where:

• \( \text{Old Rent} \) — Current monthly rent amount in USD
• \( \text{CPI \%} \) — Percentage increase in Consumer Price Index (as decimal)
• \( \text{Allowed} \) — Additional fixed amount allowed by local ordinance

Explanation: The equation calculates the maximum allowable rent increase under California law, which is typically 5% + local CPI, but varies by jurisdiction.

3. Importance of Rent Increase Calculation

Details: Accurate rent increase calculation is crucial for both landlords and tenants to ensure compliance with California's Tenant Protection Act (AB 1482) and local rent control ordinances.

4. Using the Calculator

Tips: Enter current rent in USD, CPI percentage as a decimal (e.g., 5% as 0.05), and any additional allowed increase amount. All values must be positive numbers.
