There are three ways to get permit-ready blueprints for a residential deck: hire an architect, hire a draftsman, or generate the sheets from design software. The first two trade weeks of calendar time, and real money, for a stamped set most cities never asked for. The third produces the sheet set the same day you sell the job.
Which route is right depends on the deck. If the design leaves the prescriptive code, buy the stamp and do not look back. For the standard attached deck that makes up most of a deck builder’s year, the checklist is a site plan, a framing plan, elevations, and section details, and software that already holds the finished design can produce those sheets directly.
A licensed architect or structural engineer produces a stamped set that any plans examiner will accept. For a deck that leaves the prescriptive code, a tall deck, an engineered beam, a rooftop deck, a strange lot, that stamp is not optional and this is the right route. For a standard residential deck it is usually overkill: you wait on a professional's queue, you pay professional rates, and you get a stamp most cities never asked for. City guides say so in plain language. Seattle's own deck page states that deck drawings rarely need a stamp from an architect or engineer (seattle.gov, accessed November 2026), and Boise requires stamped structural calculations only when a deck stands taller than six feet above grade or uses designs the residential code does not cover (cityofboise.org, accessed November 2026).
A drafting service turns your sketch into clean sheets for less than an architect charges. The trade is time and back-and-forth: you are still in someone else's queue, revisions cost days, and the draftsman was not standing in the yard when the customer moved the stairs. Quality swings widely, and the plans examiner's correction letter lands on you, not on the draftsman.
The newest route skips the queue entirely. You design the deck once, in software, and the software produces the permit sheets from that design. The hours an owner used to spend redrawing the same deck three times, once for the customer, once for the estimate, once for the permit office, collapse into the design session itself. That is what Evalation Lab does for decks, pergolas, concrete, and fencing.
Every jurisdiction publishes a submittal checklist, and for residential decks the lists rhyme. Boise asks for a site plan, a dimensioned framing plan, elevations, and a footing-through-rail section view (cityofboise.org, accessed November 2026). Columbus asks for two sets covering a site plan, footing plan, framing plan, elevation with connection details, and guard and stair details (columbus.gov, accessed November 2026). Denver's deck page wants the site plan, elevations, and construction details down to the ledger connection and footing depth (denvergov.org, accessed November 2026). Austin triggers structural drawings, floor plans, elevations, framing and foundation details, once a deck is attached, tall, or over 200 square feet (austintexas.gov, accessed November 2026).
So "permit-ready" means one thing: a sheet set that answers the examiner's checklist on the first pass. Structure, dimensions, connections, footings, rails, and where the thing sits on the lot. We keep current, sourced permit guides for five metros: Seattle, Austin, Columbus, Boise, and Denver.
In Evalation Lab you design the deck in live 3D with the homeowner watching, on the first visit. When the design is settled, the Lab generates the standard four-sheet permit set from it: S-1 for the structure, A-1, A-2, and A-3 for the plans, elevations, and details. The set reflects the deck you actually sold, because it was generated from it, not redrawn from memory at midnight.
The same design drives the estimate and the material takeoff, so the permit set, the price, and the lumber list never disagree with each other. Check the sheets against your city's checklist, attach them to the application, and the permit office gets a clean first submission.
If the deck design is finished in Evalation Lab, the four-sheet set generates from it in under an hour. The other routes are measured in days or weeks, because you are waiting on a professional’s queue rather than on the software.
Usually not. Most cities publish prescriptive deck provisions, and plans drawn to them rarely need a stamp. Seattle says exactly that on its deck page, and Boise only requires stamped calculations above six feet or outside the residential code. The exceptions are real, though: engineered beams, rooftop decks, and anything past the prescriptive tables put a stamp back on the table.
A site plan, a framing plan, elevations, and section or connection details, with footing size and depth. Names vary by city, the content barely does. Our city guides for Seattle, Austin, Columbus, Boise, and Denver list each jurisdiction’s checklist with sources.
Yes. Decks, pergolas, concrete, and fencing get live 3D design in Evalation Lab today, and the pergola side has its own page at /software/pergola-design. Every other trade on Evalation gets 5-minute AI estimates instead of live 3D design.
Evalation is built for residential contractors doing $700K to $3.5M a year who have outgrown entry-level tools but refuse enterprise pricing and enterprise implementation.
Evalation costs $297 per month for the first 50 founding members, locked for life, with no per-user fees. Every membership starts with a free 14-day trial. Full breakdown at /pricing.
Design the deck in live 3D with the homeowner watching, then hand the permit office the sheet set the design already produced.
