## Key facts

| Fact | Value |
| --- | --- |
| Practice area | [Residential Tenancies](https://ailawframework.com/practice/residential-tenancies.md) |
| Human involvement | Yellow: Lawyer and AI draft together |
| How AI is used | Table the rent charged in the prior 12 months, any discount or concession the lease lists separately, the proposed rent, the date of the notice, and how many increases the same tenant has already had in that 12 months. Do not calculate the cap and do not write the reply. State law governs, and the lawyer confirms the governing state. For example, California. |
| What the lawyer must review | California Civil Code § 1947.12(a) limits an increase over 12 months to 5 percent plus the percentage change in the cost of living, or 10 percent, whichever is lower, measured from the lowest gross rental rate in the prior 12 months. Discounts accepted by the tenant are excluded from that lowest rate, and the gross rate and the discounts must be listed separately in the lease. The same tenant may not have more than two increments in 12 months. You apply the exemptions, the local CPI the section names, and Civil Code § 827, which was not opened here. State law governs, and the lawyer confirms the governing state. For example, California. |

## Checking plan

- What the AI does: Table the rent charged in the prior 12 months, any discount or concession the lease lists separately, the proposed rent, the date of the notice, and how many increases the same tenant has already had in that 12 months. Do not calculate the cap and do not write the reply. State law governs, and the lawyer confirms the governing state. For example, California.
- Basis: Checked against the linked sources on 22 October 2026. Confirm the current instrument before reliance.

## Notes

- A new tenancy in which no prior tenant remains may start at an initial rate outside subdivision (a). Later increases are capped.
- Housing with a certificate of occupancy within the previous 15 years, some owner-occupied duplexes, and some separately alienable homes are outside the section only if the stated conditions are met. Do not assume an exemption from the address alone.
- The notice period in Civil Code § 827 was not opened. Do not invent it.
- State law governs; confirm the governing state before relying on this.
