If a Tenant Signed Lease in June How Will AB 1482 Affect It?

[Kevin Fukushima]

Tenant renewed at a higher rate than 5%+CPI in June. Will it revert back to what they were paying pre-March 15th even if they signed a year long lease? (50+unit apartment owned by an LLC)

Here is my example:

Tenant lease from 6/1/2018-5/31/2019 at $1,000

Lease renewed from 6/1/2019-5/31/2020 at $1,200

This is a 20% increase.  New law would allow an increase to approx. $1,080.  But since the lease was renewed at this 20% for a whole year before the law was passed, will it stay at this rate come January 1st 2020?  Or will it revert back to $1,000 + 5%+CPI on January 1st?

Thanks
