The demo is all done, barebones inside, but it may still need a little work done on the outside in addition to complete internal refinish.

Does your build price include demo of the existing?

Unfortunately, their demo already included the garage doors, 6 windows, a half bathroom, staircase, the exterior siding, all the wall and ceiling insulation, and they poured new footings and framed in the garage opening.

For the example above the lot was sold for $800K+, which further reduces the budget left for construction (demo existing property, clear the lot, excavate, etc.). 

(or call you so they can demo next time it happens if they can't make it happen on demand)3) Adjust place as needed for legitimate placement issues.4) If failure to keep smoke detectors working is a breech of your lease then do a formal notice to cure as required by your state just to have it on record.
