I have seen quotes on here several times that as a ballpark figure, you can budget for $100k per floor (not including kitchens and baths).

Can anyone break that down for me? I’m having trouble figuring out how it comes to $100k per floor MINUS the kitchens and baths.

Based on rough quotes I’ve been given from contractors, it seems that these are the main components:
-$15-20k electric + plumbing
-$15k new floors (if we go with pre-fab floors on a roughly 900sq ft place)
-$15-20k new interior walls and doors

Even being generous, that doesn’t come close to $100k. Where am I off in my estimates, or what else am I missing?

Thank you!

  1. I just received 2 estimates for a complete gut renovation for 4 floors with 1400 sqf each. I was given a low estimates of $500-$700k, and a high estimate of 1.5 mill. What gives? This seems so expensive to what others are saying on this thread.

  2. If you are renovating an old brownstone, you may find your cosmetic work leads to much more intensive work than you initially expect. I refer to these as the “hey lady, look at this” moments.

  3. Cosmetic work should not cost you anywhere near $100K a floor. When people on this site quote those numbers, they are speaking of gut or near gut renovations.

  4. Thank you very much all!!! I realize how naive my question was- I was just trying to get a sense of where that quote came from. Your info has been VERY helpful!

    To be specific, we are hoping to just do cosmetic work fo 2 units (2 floors), incl. new kitchens and baths (but lower end stuff). I anticipate new floors, new kitchen, new bath, likely some new electrical b/c of adding some track lighting in, and other cosmetic stuff (new paint, maybe some wall sanding, etc.). I was hoping to get all that done for below $100k per floor. Sounds like its doable.

    The owners duplex sounds like it’s highly likely to exceed $100k per floor, which is understandable.

    Thanks again!

  5. depends on whom you hire. i did 3 floors a year back. thats six units total gut with new everything. cost me only about 100k per floor. but thats double the work. so about 50k per unit.

    right now i’m doing 3 units about 180k for almost all. but this guy is slightly more expensive than my last guy. my last guy already taken up too many projects.

  6. Having just done a gut reno in excess of 100k/floor – here are things that could drive up the #:

    1) Electric & plumbing – are you combining apartments, changing location of plumbing stack (gas, water), adding central heating or A/C, upgrading electrical service, new boiler
    2) Structural issues that require replacement of joists/floor boards
    3) How much demo, and how much in the way of new walls, skim coating, installation of light fixtures in ceiling (recessed lighting for instance) – how much is your floorplan changing
    4) New doors, closets
    5) Venting for washing machine dryer
    6) New windows
    7) Stripping and repair of woodwork
    8) Staircase repair
    9) Facade work
    10) Repair/replacement of roof
    11) Waterproofing basement
    12) Landscaping

    It all adds up – that’s not even including what you spend on kitchen fixtures, appliances, bathroom fixtures, tiles,
