16x12 Deck Plans With Front Stairs
A 16 foot by 12 foot ledger-attached deck, 4 feet off the ground, with a straight stair centered on the front edge. This is the plainest deck in the library and the most common one built: a rectangle off the back of the house with one flight down to the yard.

Common questions
Do I need a permit for a 16x12 deck with Front Stairs?
Most jurisdictions require a permit for an attached deck. Your building department will typically ask for a site plan, framing plan, elevations, structural details, and the ledger attachment detail. This set includes all of those. Check with your local building department for their specific requirements.
How much does a 16x12 deck with Front Stairs cost to build?
The materials and cost estimate in the free planning set comes to about $7,200 for this design, with composite decking, the Fortress rail, 8% sales tax and 5% for waste, at average home center prices. Your region and supplier will move it. Labor adds $15 to $35 per square foot if you hire a contractor.
What size lumber do I need for a 16x12 deck with Front Stairs?
This design uses 16" on center for the deck frame, set 4'-0" above grade. Every member size is calculated from the IRC 2021 prescriptive span tables, with the code section cited on the framing plan.
What is included in the free deck plans?
The free planning toolkit includes two documents. The planning set has the deck layout with dimensions, a materials and cost estimate, and a lumber cut list. The build guide explains how and why, from digging footings to the final inspection. Together they are everything you need to plan the build, price the lumber, and understand the construction before you start.
What does the permit set add?
The permit set ($29.99) adds framing plans with IRC 2021 code citations, elevations, structural details, general notes, a site plan drawn from your actual lot and house, and a title block with your name and address on every sheet. It is what your building department needs to issue the permit. The free planning toolkit does not include permit drawings.
