I just bought it in the fall and am trying to complete a bunch of modifications during off-season (e.g. metal roof, certain safety features, treating the deck, possibly updating the fire pit area, etc). 

It's an asset that will continue to grow as more and more people and institutions begin to adopt it as a safer hedge against inflation than precious metals. 

I love how you mixed the metals too.

Should be on a metal placard on each trailer.

Would you think a store that had a small step at the front would be compliant if they had a small metal portable ramp they could lay down over the stairs in case someone in a wheelchair were to come?

They sealed the entrances using metal screens (one around a pipe), but now the areas look unsightly.Additionally, there’s ongoing construction in the condo complex, which may have driven the mice into my unit.

We had to bring the 1925 house to 2023 code which involved un-installing 26 windows that were already nicely installed (in appearance) in the house, reframing them to 2023 standards (at the time) which also involved strapping the bottom of the wood framing with metal straps (mind you this all after we had already completed the inside renovation).  

All of the metal for the metal roof, is imported as coils for the roof and flat metal for the beams/rafters and purloins. 

I know they are compensated per unit for the inspection, do you think it would be an issue if I just registered a fifth unit and made sure it met all the requirements?

I'll go with @Greg Scott line set metal cover idea and @Chris Seveney idea for painting the copper white.Thanks folks!
