You not only have a safety issue, but your insurance company may not insure you if something was too happen, you have a code enforcement issue, and you are exposing yourself to legal issues if someone gets injured up there.

If the bank does a title search and sees a trust owns the property, they typically won't enforce due on sale and they can't see who is the beneficiary of the trust because that is not on file publicly.

If they are VERY professional, they will have their processes in writing as verification that it is enforced equally and fairly by their entire staff. 6.

The bigger question is - would be enforceable in court?

There is a reasonable chance that you could be required to convert it back to a 2 bedroom, so you would have paid for the extra square footage I would expect to pay for the original square footage and have the price discounted from that for the extra hassle and risk of dealing with the code enforcement officer 

I work in Law Enforcement and my hobbies are surfing and kayaking.

MY advise is enforce a lease that calls for prove of renters insurance with pet rider with dog breed included. ...vet and shot records.. most of all meet the dog of course REMEMBER ANY dog can bite or be aggressive or a plain pain with barking etc...use common sense.

At that point in time you get rid of him.Strict enforcement of your rules begins with new tenants. 

That we are not going to look the other way, that we enforce our agreements.It is very difficult to monitor, hard to prove whether people are truly living there or just there a lot. 

It also has some built in calculators as well.Rentometer.com - You also can use this to assist in determining rent ranges.Permits and Enforcement searches - http://permitsandcases.indy.gov/citizenaccess/This is my absolute favorite tool for research.
