I feel like I need to re-bill this to the tenant since she made an unnecessary service request and that I shouldn't have to pay for it.  

Do you give your tenants until the 5th in case it is in the mail (although I would still impose the late fee)? 

., they inevitably would look worried about everything, and start pointing out unnecessary fixes that they thought should "also" be fixed.  

On the other hand I see a pet deposit as a unnecessary fee.

I'm hoping to be able to keep my building no smoking and pet free (when I get one) and curious if there are any restrictions Minneapolis imposes on landlords.

Newbies trust their life savings with strangers who are all-too-happy to provide "turn-key" investments that end up failing, due to their (I think deliberate) bad management and unnecessary maintenance costs, etc., and then they are happy to sell it for you - and do it again to the next sucker.  

We realize that many families like / desire pets however, all pets do impose a significant amount of wear / tear / and sometimes permanent damage and odors to our properties that can be difficult / costly to remediate Pet/Animal policy: 1.There will be a $400 non-refundable yearly fee for up to 2(two) small pets (e.g., the yearly Pet fee is $400 for either 1 or 2 small pets).

If it turns out your letter was unnecessary, fine.  

They'll charge them to find the tenant, to do the eviction, tons of unnecessary maintenance, to find another loser tenant, if the landlord is still dumb enough to keep them, and when the landlord finally wises up, they'll charge a fee for firing them, then let another sucker in the door.  

Unless you did very poor DD I bet a lot of the other stuff you described was unnecessary as well.
