AI Drafting for Multifamily and Apartment Projects

A 240-unit apartment building is a dozen unit plans mirrored and stacked up five floors, and every one of those units still has to meet the dwelling unit rules in NEC 210.52 and the Fair Housing design requirements. Nomic drafts the unit plans, floor plans, and plumbing stacks in CAD in your standards, then checks each unit against the code and the accessibility type it is tagged as before your engineer or architect reviews and stamps.

On the sheet

Floor Plan, annotated

An architectural floor plan with walls, doors, room tags, and the column grid every other discipline draws on.

  1. 1Exterior wall with window openings
  2. 2Door, swing, and door tag
  3. 3Room name and number
  4. 4Partition type tag

The problem

Twelve unit types, 240 units, and one wall that moved

On the unit matrix, A1 and A1-R are mirrors. On the floor plans they rarely are: the reversed unit picks up a column, a trash chute, or a corridor door that did not flip, so a copied power plan puts a receptacle behind the entry door or leaves a stretch of kitchen counter more than 24 inches from the nearest receptacle. Stacked units also share wet walls, so a chase that shifts on floor 3 has to line up with floors 2 and 4 or the stack offsets.

Accessibility adds a second layer. Most units in a covered building have to meet the Fair Housing Act design requirements, usually through ICC A117.1 Type B, and the building code adds a smaller share of Type A units scattered across floors and unit types. A Type A kitchen with a lowered work surface means that unit no longer matches its stack, and the enlarged plans have to track which unit is which through every revision.

01 / Unit plans

Unit power plans drawn per type and carried up the stack

Send the unit plans, the unit matrix, and the floor plans. Nomic lays out power and lighting for each unit type and its mirror as separate plans, then places the right version in every unit on every floor, with the load center, range, and dryer receptacle on the walls the architect drew.

  • Small-appliance, laundry, and bathroom circuits per NEC 210.11(C)
  • AFCI and GFCI protection noted by room and location
  • Unit load center placed with its working space clear
02 / Accessibility

Type A and Type B units checked one by one

Nomic checks each unit against the accessibility type it is tagged as, using the ICC A117.1 edition your building code adopts, and checks the dwelling unit receptacle rules room by room. Units that drifted from their type during a revision come back as findings.

  • Switch and receptacle heights inside the reach range for Type B units
  • Type A kitchens and bathrooms against their clear floor spaces
  • Type A unit count against the building code requirement
03 / Plumbing stacks

Plumbing stacks that line up floor to floor

Nomic draws the unit plumbing plans and a riser for each stack from the floor plans, then checks that each wet wall lines up with the one below it. Where a fixture moves off the stack, Nomic flags the offset for your plumbing engineer rather than drawing around it.

  • Waste, vent, and water risers drawn per stack
  • Fixture units totaled by stack for the engineer to size
  • Chases that do not align flagged floor by floor

Checked against

The code and documents behind every sheet

Name the editions the project is designed to and Nomic checks its own drawing against them before handing it back. Your engineer or architect of record makes the final call and stamps the set.

  • NEC 210.52 and 210.11(C) dwelling unit requirements
  • NEC 210.8(A) and 210.12 GFCI and AFCI protection
  • ICC A117.1 Type A and Type B units
  • Fair Housing Act design requirements
  • IBC Chapter 11
  • International Plumbing Code or UPC

How it works

From a sentence to a stamped set

  1. Step 1

    Ask for the drawing

    Say what the sheet needs to show and attach the backgrounds, markups, cutsheets, or photos. A sentence is enough to start.

  2. Step 2

    Nomic drafts it in CAD

    Nomic works in CAD on its own computer, on your layers and blocks, following how your firm drew the same thing before. It saves real DWG files to the project.

  3. Step 3

    Nomic checks its own work

    The drawing is checked against the code editions you name and the source documents. Everything Nomic drew is clouded, and open questions are listed.

  4. Step 4

    Your team reviews and stamps

    Your engineers and architects review the clouded changes, make the final call, and issue the set under their own stamp.

FAQ

Frequently asked questions

Yes. Nomic works in CAD on its own computer and saves DWG files for enlarged unit plans, floor plans, and plumbing risers. It lays out each unit type from the architectural plans, places every unit on every floor, and checks the result against NEC 210.52 and the accessibility type before your team reviews it.

Nomic draws each mirror as its own plan instead of flipping a copy, because reversed units often pick up a column, a chute, or a door that did not flip. Where a mirror differs from its parent unit, Nomic notes the difference so your team can confirm it.

Nomic checks each unit against the ICC A117.1 edition your code adopts for the type it is tagged as, and compares the Type A count with the building code requirement. The architect decides which units are Type A, and the final call on Fair Housing compliance stays with the architect of record.

Nomic drafts the unit panel schedules and totals the connected load, and it can size per the load calculation method and tables your engineer sets. The engineer of record chooses the method, reviews the result, and makes the final call on feeder and service sizes.

No. Nomic works in CAD on its own computer and saves DWG files you open in AutoCAD or any DWG editor. For multifamily projects modeled in Revit, Nomic delivers DWGs and change lists your modelers link into the model.
