Residential deck design · code-checked

Build the deck.
Pass the inspection.

Enter a few measurements. DeckForge draws the framing, checks it against the IRC and the code data recorded for your location, and hands you a permit-ready plan set.

IRC 2021 §R507AWC DCA650 state baselines + 26 metrosDeterministic — no AI, no guesswork

Four steps to a submission

The same flow whether you’re a first-time homeowner or a framing crew — plain-language when you want it, exact numbers when you need them.

01

Design it

Size, height, framing, railing, stairs — the plan draws itself as you type.

02

Check the code

Guards, spans, footings, ledger, stairs — each issue cites the code and the fix.

03

Match your location

Frost depth, soil bearing and adopted edition from your metro or state data.

04

Export the set

Plan drawing, cut list, and compliance report — built for permit submission.
