Finish Floor Elevation Recomendation

Recommended Posts


I am new to this and need help determining what the finished floor elevation for this particular site and layout should be.  Lot 2 is where the house will be built.  My first inclination is to go with a 394' elevation since that is the elevation the driveway will come in at.  But that will result in a higher retaining wall on the south side of the property where there is a steep slope.  Any suggestions are greatly appreciated

Are you asking where you should place the house on your lot, or what numbers to use within the program?


You normally use the subfloor (or slab) top as your reference and set at 0 (zero), not the finished floor, which may vary. Carpet, wood, tile etc.


And ...


Answers often depend on what title (Suite, Pro etc) and version (2014, 2015 etc) you are using.


You can help everyone by adding this info to your signature (see mine for an example) by clicking on your user name at the top right of the page, click Account Settings, then Signature on the left.


Doing so makes it always available, and keeps others from having to hunt for it.

     Generally speaking, the higher the better.  Preventing water from entering the house is paramount, especially in your situation building so close to the bottom of a steep slope.  Setting your 1st floor elevation at 394' will mean your driveway entering the garage is completely flat.  Typically a slope away from the house is preferred to keep water from pooling and entering the garage. 1/8" to 1/4" per lineal foot should be plenty.  Additionally, most municipalities require the landscape around the house to be graded such that there is a 2-3" slope away from the foundation out to a 10ft perimeter.  

     Depending on the amount of excavation you are willing to do on the south side, I would start with the top of your foundation wall at least 396' (Preferably 398').   Also, observe the properties around you and how they are sloped, you don't want to create a dip in your backyard for water to pool in.  

     Having the house at a higher elevation will also help with the view and looking over the house in front of it.


Hope this helps and good luck with your project!
