I personally paid for similar ads in the local Houston newspapers, and regional edition of the Wall Street Journal.3.

Quote from @Jaron Walling: You should already have insurance on this property BEFORE closing.  

Opening a few walls, updating kitchens and baths, flooring lighting, etc.

I think if you were sharing walls or in same house, then certain quiet hours in lease or noise restrictions can help prevent some issues. 

There may be ways to share space but give the impression of a separate unit (such as an unpermitted wall up to create separation). 

In my area, not only is there zoning regulations, but building regulations where 3 families are built to different building standards, such as cement walls for boiler rooms, sprinklers, fire escapes to name a few.

That shouldn’t be too hard either because the kitchen and bathroom are right next to each other only separated by a wall (would just need to figure out the hose bibs). 

Is changing a broken wall plate a "service" according to this section?

Things to look out for are old windows, old wood siding, peeling paint on exteriors and interiors, and damage to window sills, door frames, and walls.
