Background check is clear for all adults.

Twenty-four hours is presumed to be a reasonable notice in the absence of evidence to the contrary.(9) Promptly commence an action under Chapter 1923. of the Revised Code, after complying with division (C) of section 5321.17 of the Revised Code, to remove a tenant from particular residential premises, if the tenant fails to vacate the premises within three days after the giving of the notice required by that division and if the landlord has actual knowledge of or has reasonable cause to believe that the tenant, any person in the tenant's household, or any person on the premises with the consent of the tenant previously has or presently is engaged in a violation as described in division (A)(6)(a)(i) of section 1923.02 of the Revised Code, whether or not the tenant or other person has been charged with, has pleaded guilty to or been convicted of, or has been determined to be a delinquent child for an act that, if committed by an adult, would be a violation as described in that division.

If the tenants are young adults without children, then many of them will only use a shower (though, there might be a few occasional ones who are looking for a tub). 

They can also be removed by an adult in the event of an emergency.  

And quite frankly, now I'm scared.John Taylor Gatto, a retired school teacher and activist critical of compulsory schooling, asserts, "We could encourage the best qualities of youthfulness – curiosity, adventure, resilience, the capacity for surprising insight simply by being more flexible about time, texts, and tests, by introducing kids into truly competent adults, and by giving each student what autonomy he or she needs in order to take a risk every now and then.

The 2 tenants already had 1 dog, their son has brought in another.To account for this 3rd adult and 2nd dog (not on the lease) I believe I should do the following: 1.

Let's say I have a tenant for many years who is suddenly being inconsistent with rent payments, or an adult member of the household becomes suspicious, e.g., complaints are received about an adult child's criminal behavior.

(I had a bout of adult onset asthma and I don't want anyone else to go through that)

But if it's not reasonable, you need to get it to market rates.Basically you want to talk to the person adult to adult.

It's not proper remediation, it's illegal to not do proper remediation and if you think selling a remediated house might be a stain on your reputation, try selling one where you claim to have remediated it but haven't (which is what this advice is).Meth is nasty, nasty stuff causing advanced and rapid neurological damage in children and pets and slower, but no less advanced neurological damage in adults.
