I will hopefully be building by this fall and was wondering how many concrete piers (four feet in the ground) will I need to make for a 16x24 camp/home? Thanks Danny

That depends. What size floor joists will you be using? How many stories is your building going to be? Most likely you'll be able to space your piers about eight feet apart, so you'd need twelve of them. But do some research on what size joists you need to span different distances -- you might be able to reduce that to nine, but that would probably be the minimum. Kathleen

Don't just speculate. Nearly every lumber store has charts that tell you loads based on your floor joists and spacing. Also depends on if you are using 2 x 4 walls or 2 x 6 etc. Our house turned out to require 2 x 10's on 16 inch centers for floor joist and our piers are 5 ft apart with solid block perimeter. It is single story with a loft.

Our 16x24 guest cabin uses four posts (6x6") along each of the 24 foot sides. On the 16 foot ends, there is an additional post in the center....making a total of 10 post total for the cabin. The floor joist are 16ft long 2x12's. The porch added an additional 6 x 16 feet and used another three posts.
