Me, I hope never to see the underside of a sink ever again.

Years ago, in NYC, I used to hide a key in a magnetic key box outside attached to the underside of metal stairs. 

These planks that looked pretty nice got pulled up and showed an underside that looked, felt, and smelled like cat piss jelly -  thick.Now there is a layer of 12x12 linoleum glue down tile that was underneath the LVP.

With that amount of urine, it has soaked through to the underside which you can't seal from above....best to replace.  

Make sure the underside of the trailer is intact for one.

The bracket he used attaches to the underside of the eaves and curves above the roof so no cables running over or in the gutters.

It also comes with a spare key, which I will have in a realtor's  lockbox on the property (currently screwed to the underside of my deck).

I don't believe a permit was ever pulled for this.I was going to fix it up to make it safe for use again (it has exposed nail points on the underside of the roof, and the floor is sagging in some areas).However, what I'm wondering is: even if I fix it up, and a tenant gets injured in there anyway (trips and falls) and sues me, will my insurance deny liability coverage anyway, if they find out it doesn't have a permit?

Then again, the tunnels could be on the underside of the subfloor which is why it's important to go down there and get eyes on it.
