10×12 Deck on Posts Plans FAQ

What is a deck on posts?

A deck on posts transfers the platform loads through beams and vertical posts into concrete footings or another approved foundation. It can be freestanding or coordinated with an attachment to the house.

What should post-supported deck plans show?

The drawings should coordinate the deck footprint, finished height, joists, beams, posts, footings, stairs, connections, dimensions, and elevations. A site plan may also be required for permit review.

How high is the example deck?

The reference scene is raised 29 inches above grade and uses four stair risers. The height, stair geometry, and guard requirements can be adjusted for the actual property and local code.

Can the post and footing layout change?

Yes. Deck size, beam spans, soil conditions, frost depth, attachment, and local requirements can change the number, size, and spacing of posts and footings.
