Building more than 2 Stories

[Lynn Currie]

Hello BP Nation!

I do residential development in Austin and all of my projects have had a 32' height limit, meaning that I don't go up more than 2 stories. 

I have a project that I'm picking up that has a different type of zoning, allowing me to go up 60'.

My question, what percentage should I plan to add to my budget to accommodate for any extra structural needs?

@Karen Margrave  @Will Barnard Any thoughts on this?

Thanks!
