Lease Is Up In 5 Days, Landlord Gives A Renewal With New Clauses At The Last Minute

(California)

Hi,

Our landlord just shared with us a renewal lease notice with new clauses, including a tenant protection act (TPA) exemption notice, telling us we have three days to sign (during memorial weekend), while our lease expires in 4 days. We're not able to get legal support as this is a holiday, and we're not willing to sign because the automatic month-to-month would offer us more legal protection as we would still be covered by TPA.

They claim that the renewal lease is materially the same as before while it does contain changes (including a rent increase), and that not signing in time would be considered a refusal. It's seems a shady way to evict us under the tenant protection law, but I couldn't find any Californian law specifying how much of a notice a landlord has to give for a lease renewal. I'm saying "shady" because the landlord initially tried to tell us, 20 days ago, to vacate the premises at the end of our lease, and we told them that we needed more time to find a place, and would go month to month as authorized by TPA. They weren't aware of the law then, but are now trying to find ways around, rather than accepting a month to month tenancy. There's no just cause involved, all of our payments have been made in time.

TL;DR :

• can I refuse a lease renewal that was sent 5 days before end of lease with no time to consult legal aid, and not be at risk of an eviction? Since it includes a rent increase, shouldn't it be at least 30 days anyways?
• is adding a TPA exemption notice and some slight other changes (e.g new rules about cleaning) considered as "material changes" under the law?
