Don't assume that just because you want someone out, even though it may be your property and your right, that they will magically have someplace to go, and will comply without resistance. 

I have complied a list of COVID-19 resources for landlords in the Chicagoland area.

I also have a lawyer taking care of my contracts to make sure they comply with the agreement and protect the investment.

It sounds like your tenant complied with that. 

If you're unwilling to comply with my policy, then I'm sorry to say you won't be able to rent from me."

— no one had a problem with this and everyone complied. 4) I told them upon entering that I would open/touch all doors, drawers, closets, light switches, etc... so as to minimize surface contamination.

(Yes, is annoying and stupid and your situation is exactly the grade A example why) I would verbally communicate with the tenant and explain (in a 'nonthreatening') manner - don't use the terms like fine, fee, or "eviction" - that based on your understanding that they have not been impacted personally by COVID-19 insofar as income or ability to work that they should be able to, and you do expect them to continue to pay rent,   and while you will comply with all emergency orders, unpaid rent will continue to accrue and is expected to be repaid.    

Possibly, but probably not in CA, but it may scare the tenant enough to comply. 

I recently found a very good foreclosure on Homepath.com, submitted an offer which was accepted, did home inspection, and then found out that no title insurance company is willing to insure this property because all foreclosures in Massachusetts are pretty much void because they did not comply with the correct notices for one reason or another, and also foreclosing banks often did not even have the papers showing they have the right to foreclose in the first place (they lied about it in court to get through this routinely, but eventually judges stopped letting them do this).

As Mr Brandon Turner mentioned in his book on "Managing Rental Property", we always require our tenants to pay deposit and first month's rent before or during lease signing via confirmed payment such as demand draft or cashiers check.Due to pandemic and to comply with our social distancing guidelines, we are planning to do e-sign this time and not meet if possible.
