I ended up demo-ing the stairs (after paying a fee for a demo permit $75) and getting some foldable steps that ppl with RVs use to make stairs that can be packed up to go. 

Not much you can do to keep them from spreading between units unless you were to demo your walls and seal the party walls against rodents.

Demo, Frame, Rough Electric, Rough Plumb, Insulate, Sheetrock, Tile, Exterior Trim/Paint, Plumb Materials, ...

If it's really old we just tear it down and figure in demo costs with purchase price when we acquire it.It's common regardless what the lease says for options for tenants to ask for concessions.

But if I have to completely  demo the addition I'm sure it'll cost way more than $60k.

We started the demo face but had to stop and wait for the architect to finish the plans and submitted to the city for permits.Update 11-15-23: The Master plans has been approved by the city of Miami.

Take a look at the demo video linked below and if this sparks any interest or you have a similar process where something like this app could help automate, would love to hear about it in the comments! 

That being said, it's possible to get permits in retrospect, but you often have to do some demo and rebuilding based on how thorough your inspector wants to be. 

I believe different locations and demo's have different marketing approaches.

That way we can keep the bathroom and not demo the walls, unpermitted building interior work.
