We are all familiar with issues related to service animals (specially trained and certified dogs) and assistance animals (such as emotional support animals of any species or breeds).This post suggests a compromise response to those issues.Landlords who prohibit animals do so because theyfear the damage that might be caused by those animals, know it is highly unlikely they will be able to fully recover compensation from the tenant if there is damage, and fear litigation if the animals harm someone. 

Or that you're a flexible landlord willing to make smart compromises?

(And I can just hear a wife who is being compromised by her in laws.)

There is no reason to compromise like this by allowing sub-qualified tenants into your property.

Doing so compromises the eviction process.

As far as the marital issue, counseling or not, really listen to your wife about why she feels it is important to help this person, then see if you can come up with a compromise, like have him move but agree to volunteer with her at a homeless shelter nearby or something else that fulfills both her need to help with your need for privacy.  

Well, first I'll start with an explanation on what exactly this entails for those not clear of what generally compromises a bases surrounding area.

to make sure they haven't compromised the electrical system. 

On the other hand, any tenant who gives a code out is compromising their own security.  

If you're okay with the every two weeks, I think that sounds like a reasonable compromise.
