How to Design a Permit-Ready Kitchen in ArchiMaster 3D (2026)

A permit-ready kitchen design starts with a dimension-accurate room shell, not with cabinet styling. In ArchiMaster 3D, you build the shell first, place true-to-scale cabinets and clearances, add the mechanical layers a reviewer expects, then export a dimensioned plan and elevations that most local permit offices will accept as part of a residential submittal.

• Start with the room shell, rough openings, and a fixed zero point before adding any cabinets.
• A 42-inch work aisle is the single most common clearance a local reviewer checks in a kitchen plan.
• Dimension both the overall room and each cabinet run; permit reviewers look for partial dimensions, not pretty renders.
• Use separate layers for electrical, plumbing, and ventilation so the permit set can show only what the code reviewer needs.
• Export from the same model in plan and elevation views to keep every sheet consistent.

This workflow is faster than redrawing in a separate CAD side tool because 3D home design software keeps the floor plan, cabinet schedule, and rendered walkthrough in one file. Once the shell is right, schematic and permit views pull from the same model, so a change to the island updates every sheet.

“A permit reviewer rarely rejects a design for the cabinet style. They reject it for a missing dimension, an undersized clearance, or a route that does not exist in the plan.”, ArchiMaster 3D Journal

Step 1: Build the Room Shell Before Placing a Single Cabinet

Start in ArchiMaster 3D with the room tool rather than dropping cabinets into empty space. Draw the kitchen footprint from wall corner to wall corner, then set the exact ceiling height. Standard base cabinets sit 36 inches high. The cabinet body is 24 inches deep, and the finished countertop typically reaches 25 to 25.5 inches deep. With a 96-inch ceiling, that leaves roughly 60 inches of upper wall. That measurement matters because upper cabinets, a range hood, and crown molding need to be coordinated in the model, not guessed on site.

Add windows and doors as actual objects with their rough opening sizes. A window over the sink or a door swing into the work aisle can immediately expose a clearance failure. For every exterior wall, record the rough opening, finished opening, and sill height in a layer named shell or existing. A plan reviewer often checks the relationship between the kitchen aisle and an adjacent door swing, and the model makes that overlap visible in seconds.

Step 2: Place Cabinets and Islands to Code Clearances

Place base, wall, and tall cabinets from the product libraries as true-size components, then dimension each run. The work aisle between a base cabinet face and an island or opposite counter should be at least 42 inches wide for a one-cook kitchen and 48 inches for a kitchen where two people work at the same time. Walkways behind seating should stay 36 inches or more. A 42-inch dimension is not a universal legal code in every jurisdiction, but it is the practical minimum most residential plan reviewers and NKBA guidelines expect.

The non-obvious failure most people miss is the landing-zone overlap. A refrigerator door, a dishwasher door, and a base cabinet drawer can all swing into the same 42-inch aisle at once. In ArchiMaster 3D, set door swing arcs for the refrigerator, dishwasher, and any pull-out pantry, then check the clear floor space between the open arcs. If two arcs cross, the aisle dimension looks correct on plan but fails in use and can draw an examiner's note. Adjust the island depth or shift the refrigerator before you finalize the plan.

Clearances to Enter Now

• 42-inch minimum work aisle for one cook, 48 inches for two cooks.
• 36-inch minimum walkway behind a seated island.
• 15 to 18 inches of clear landing space on at least one side of a cooktop.
• Upper cabinets 18 inches above the finished counter, 12 inches deep for most wall cabinets.
• At least 30 inches of vertical clearance between the cooktop surface and the vent hood.

Step 3: Layer Electrical, Plumbing, and Ventilation the Reviewer Looks For

A dimensional kitchen plan without mechanical notations often comes back with a request for additional information. In ArchiMaster 3D, use a dedicated layer for electrical and another for plumbing and ventilation. Place outlets along the counter run so that no point along the back wall is more than 24 inches from a receptacle, and include the required GFCI-protected circuits in the island, on the counter wall, and within 6 feet of the sink. Two 20-amp small-appliance branch circuits are the baseline for most residential kitchens in North America, but confirm with the local authority having jurisdiction.

Route the range hood or microwave vent to the outside, not into a soffit that ends nowhere. In the 3D model, draw the duct run from the hood through the cabinet or chase and mark the exterior termination. If the vent must turn more than twice, note the equivalent duct length and confirm the blower spec. For sink plumbing, show the drain line under the floor or in the wall, and mark the vent stack connection. These are the exact items a building official looks for when comparing the plan to the mechanical sheet.

Step 4: Export the Dimensioned Views That Actually Get Stamped

When the model is complete, switch to Plan view and turn on the dimension layer. In ArchiMaster 3D, draw manual dimension strings from the overall room width and depth to the individual cabinet widths, appliance spaces, and the centerline of the sink and cooktop. Dimension the window and door rough openings from the nearest wall corner, not from a cabinet face. A common permit rejection is a dimension that starts at a floating cabinet edge and leaves the reviewer unable to locate that cabinet in the room.

Export a PDF of the plan view, a separate elevation sheet for each wall with upper and base cabinets, and a section or elevation showing the range hood and ceiling height. Most jurisdictions accept a clear PDF with a title block, scale note, and the project address. Keep the 3D perspective image in the submittal package only as a supplement: it helps the reviewer understand intent but does not replace a dimensioned plan.

Common Permit-Rejection Fixes You Can Catch in the 3D Model

Corner cabinet blind zones deserve special attention. A diagonal corner upper that meets a window trim with less than 3 inches of reveal will often be flagged because the cabinet cannot be installed as drawn. In the model, place the actual trim width around the window opening and check the corner cabinet face. The same applies to a dishwasher placed at the end of a run next to a wall: if the open dishwasher door hits the perpendicular wall, the plan fails in the field.

Lighting is another underchecked layer. A permit reviewer may look for switch locations at each entrance to the kitchen and task lighting over the work counters. Add recessed or under-cabinet fixtures on a lighting layer, then switch to the electrical view to show the switch legs. In ArchiMaster 3D, the full feature set lets you toggle these layers when exporting, so the same model can produce a code plan, a cabinet elevation, and a photoreal preview for the client.
