If they are on a month-to-month lease, just terminate her tenancy with proper notice. 

It does not have the proper zoning but it is build out correctly.

Are you not able to give proper notice (whatever timeframe your lease states) and then go send someone to enter the property and see it in person?

Take ownership of your mistake and learn to do the proper due diligence recommended above😊

Can I cut the glass, etc. in place to remove the majority of the weight, and then I'll just have the frame to remove? 

In your position, I would make sure to disclose the fire issue while also providing documentation regarding proper remediation and replacement.

The enclosures are 3 piece that are cut on the property to ensure a proper fit and so on and so forth.

Your deed of trust needs to be made by the trustee, or you didn't properly perfect the security interest, I'd bet on any attorney getting that right unless they were really new.Back to the other issue, any lender advertising a loan product and never closes that product can get nailed.

I guess the owner would have to weight the cost vs benefit.
