An attorney who specializes in unlawful detainers would be a great place to start.

Are there any unlawful detainer attorneys available to answer?  

However, if a tenant were to just ignore it, then you would proceed with eviction (unlawful detainer). 

A structure is unfit for humanoccupancy whenever the code official finds that such structure is unsafe, unlawful or, becauseof the degree to which the structure is in disrepair or lacks maintenance, is unsanitary, vermin orrat infested, contains filth and contamination, or lacks ventilation, illumination, sanitary orheating facilities or other essential equipment required by this code, or because the location ofthe structure constitutes a hazard to the occupants of the structure or to the public.

I did this once and called the appraiser roughly 3 weeks later and it was like a bombshell, he again said you bought it for so low I told him so your punishing me for a deal that I found and no one else?

I can only have maximum of 3 strangers occupying the property which makes it unlawful to rent to group of five roommates.

I did find that the CDC completely overstepped its authority and ordered a blanket national moratorium on evictions until December 31, but at this point, I still had not received any official CDC Declaration from my tenant.So I responded that he's made no effort to pay or to provide evidence that he will pay and that I would be filing the unlawful detainer the next day.

If the tenant fails to make this payment, an unlawful detainer (eviction) can be filed against them beginning February 1, 2021. 

Give you benefit that is unlawful (mostly relevant in cases of self-directed IRAs and 401ks, but it's worth considering).So long as you document things properly and make sure it is above board by speaking to a tax attorney and/or your CPA it could work out interestingly :) 

I don’t know why you’re being advised to go through an eviction based on the circumstances you presented.You wouldn’t file an eviction against a tenant who has stated they’re moving out, and then voluntarily moved out and returned the keys as agreed.An eviction (unlawful detainer action) is only done to recover possession of a property that someone is refusing to voluntarily return to you.If you still need to recover money from them after they’re out, then you typically go through small claims.
