Triplex some years ago require fire escapes, cement walls for furnace rooms.

I recommend the "clean unfinished" look for MAX ROI: Spray paint ceiling flat black, painted white walls, and epoxy gray/blue floor (or just cement basement paint).

Planning for back yard cement work.

Pavers or cement is an upgrade from asphalt.3.

Appears they glued the access to the crawl space shut and added cement to the exterior of the building to try to make it look like new foundation was poured or something.

The correct fix would be tear it all out, cement board the whole tub surround, redgard to create a waterproof surface, and then tile. 

., this is obvious.5>As mentioned above , just a few are getting tons of cash - which means they can buy out business and other companies at very low cost and this means further super consolidation of power - literally cementing it in place. 6>The future for the average citizen is not looking good. 

There is still a lot of thin set sticking to the cement board should I just scrape that off to get it level again or is there a better way?

The liner was also cemented around at the top of the chimney.

It wouldn't meet building codes, back then, 3 families requires fire escapes, cement walled furnace rooms which two families do not.My duplex has a CO for 2 in the buildings department, and the finance department listed it as a 3 family.
