Questions:What is the most effective strategy for doing a demo of this size?

Hello, I've recently purchased a fourplex in inglewood and am about to start demo on one of the units.  

Because of this, we used locals for the unskilled labor (demo and clean-out), but because I live an hour away from the property, I wasn't able to monitor them closely (Mistake #3).

Phase 1 can be light, plans, permits, demo, etc but nonetheless expect to expense additional capital on top of the 10% + closing costs. 

Tried to give mobile away for free, no takers so we demo-ed it.

2- things the owner has to deal with , boarding up the property, making it safe,  maybe even having to fence it off. these items cost money and a continual nightmare for the owner until it is sold or demoed!

Will you need a permit to demo? 

So if you aren't doing demo you may not need to worry about this.

If there is a same day test for both, please let me know.The demo materials that are trash generally I’ve seen crews utilize a dumpster or stack these materials outside, which was why I was shocked to see it all piled inside with water dripping on them, while the items we were salvaging for the remodel (the kitchen cabinets) were stored outside in the elements and got rained on.

You will also need a permit to demolish which comes with an associated inspection post demo.
