My question involves landlord-tenant law in the State of: California
I have been living in the complex for about 6-7 years. This afternoon I received my notice that it is time to renew my lease, but when looking it over I observed that the 12 month lease appears to be a few days short of a full year (10/19/2017 - 10/14/2018). Looking back over the past 5 years there is a trend of the lease being 5 days short of a full year (6 during the leap year). There is a moderate rent increase each year, which ends up being prorated because the lease is no longer ending at the end of the month.
Is this something that is worth raising further questions about or is it more of a common practice?
