Sorry to hear you’re going through this ordeal with your tenant, but I don’t see where you have any grounds now to file an unlawful detainer action for the smoke detector incident. 

And this keeps tenants from playing you, for extended months, waiting for a court date, so you can get what's called an unlawful detainer, so the police can be called in to man-handle the offending tenant out, if need be.

Case type is unlawful detainer. 

It took literally 1 year and 1 month to remove the tenant from the moment we filed the unlawful detainer (we filed this ourselves before hiring an attorney) through jury trial (the owner can represent themselves during these proceedings up until it goes to jury trial, that's when we had to hire an attorney) and finally the Sheriff's lockout.  

Although some think it's clever, you don't want it to significantly impact your success.First, the term "Realtor" is copyrighted and it is unlawful to use as part of your company name, it also requires the ® symbol when used.  

This includes attempts to collect, or threats to collect, through a collection agency, by filing an unlawful detainer or other judicial action, withholding any portion of a security deposit, billing or invoicing, reporting to credit bureaus, or by any other means.

If the lender is an LLC or corporation, an attorney is mandatory because otherwise is unlawful practice of law. 

Personally, i'd serve notice to any possible residents, of a pending unlawful detainer (or whatever its called in your jurisdiction) by an eviction attorney before doing anything but if you are sure its not occupied, and you have legal ownership, you should be able to do with it what you see fit. 

Allen Humphries you mentioned your lease doesn't say who does what.Loose contracts like that when they go to court tend to have the whole lease or parts of it deemed unenforceable by a judge in a court of law for being unlawful or too vague.Just because something is written in a contract doesn't make it legal or enforceable.Just like tire flaps on big trucks saying they are not responsible for flying rocks etc. so some people read and believe that stuff.
