Well, we were just notified through a neighboring towns police dept that there is now a sex offender within range of us, less than 1000ft roughly.

Educate all your tenants on how to report noise complaints and let the police handle it.

In CA, would it be harder to get them kicked out using the police department? 

Unless it can be established that they are scamming enormous sums, the police, FBI, attorney’s general, and the like, have bigger fish to fry and won’t lift a finger.

You wrote commercial, but then talked about offices specifically. 

I have a rental property in Detroit that I am looking to get certified, and have tried following the process on the Detroit Housing Commission website (https://www.dhcmi.org/landlord-faqs), which says " To list your property with the Detroit Housing Commission (DHC), you can visit DHC’s Assisted Housing Division office located at 2211 Orleans, Detroit, Michigan 48207.

Assuming this is an 8 cap neighborhood you'd have a ~$420-450k value within a year (unless property taxes are crazy high) when leases would renew since it'd be valued as a commercial building with the office space.

Office space is gutsy at this time with many companies working remotely, maybe part of your investment was to bet that people will be coming back to work in person.  

So, now rather than it being a "legal" issue, you just call the police, they are forcefully thrown out. 

If you are purchasing a primary home, income could be a challenge if you work at an office.
