Steel Frame Homes in New Jersey

A steel frame barndominium uses welded rigid frames, the red iron of the trade, bolted to a concrete foundation, with steel purlins and girts carrying the roof and wall panels. It gives wide clear spans with no interior posts, which suits a shop bay or an open great room. In New Jersey the frame is designed to the 2024 International Residential Code, New Jersey edition, with its footings below the frost depth the state sets for your county and its members sized to the snow and wind loads looked up for your exact site.

Steel Frame Homes: how the work runs

Four stages, in this order. The sequence matters more than it looks: settling the zoning, the septic soil tests and any Pinelands, Highlands, coastal or flood review before anything is fabricated is what keeps a New Jersey build from stalling.

1

Span, bays and openings

The width of the clear span, the bay spacing and the size of the big doors set the frame. We fix those with you first, along with any loft or mezzanine, because every later drawing depends on them.

2

Loads for your address

Under the Department of Community Affairs Bulletin 19-1, snow and wind loads come from a site-specific lookup for the exact location, and they change with elevation. One- and two-family dwellings are exempt from the code's seismic provisions in New Jersey, so snow and wind govern the frame.

3

Foundation and anchor bolts

Frame columns bolt to a slab or perimeter foundation with footings below the state frost line: 36 inches in Mercer and Middlesex counties and northward, 30 inches in Monmouth and Burlington counties and southward. The anchor bolt layout from the frame drawings is set before the pour, and the construction office inspects the footings.

4

Erection and close-in

Columns and rafters are stood and braced, then purlins, girts and panels follow. The frame is inspected before it is covered, and the building is closed in so interior work and the licensed trade contractors' plumbing, electrical and HVAC can start.

New Jersey fixes the frost depth statewide and leaves snow and wind to your exact address

The New Jersey edition of the residential code sets two frost depths for the whole state, 30 inches in the south and 36 inches in the north, and exempts one- and two-family dwellings from its seismic provisions. Snow and wind are different: Bulletin 19-1 sends designers to a hazard lookup for the precise site, because the values move with elevation and location. A steel frame is sized to that answer, not to a catalogue default.

Where we deliver steel frame homes

In New Jersey the line that matters is the municipal boundary. The construction code is the same everywhere, but each municipality has its own zoning and its own construction office, or shares one, or uses the Department of Community Affairs as its enforcing agency. Counties issue no building permits. Cross a town line and what changes is who reviews the drawings, how the land is zoned and which board of health approves the septic system; cross into the Pinelands, the Highlands or the coastal zone and a regional or state review can come first.

Every town and county we build in has its own answer on zoning, septic and regional overlays. The service area pages set out what each one publishes.

What actually decides the price

Square footage is the number everyone leads with, and it is rarely the one that moves a barndominium budget. These four do.

  • Clear span width

    Every extra foot of clear span makes the rafters and columns deeper and heavier. Adding an interior column line, where the layout allows it, can bring the frame cost down.

  • Snow and wind at the site

    Heavier northern snow or a more exposed coastal site calls for heavier frames and closer purlins than a sheltered inland lot.

  • Foundation type

    A slab on grade, a thickened-edge slab or a perimeter foundation with a crawlspace each cost differently, and soil and flood zone can decide which one the site needs.

  • Erection access

    A tight lot with trees, wires or neighbours close by can call for a different crane position or a longer erection schedule.

Steel Frame Homes in New Jersey: common questions

8 questions we get asked most often about building in New Jersey. If yours is not on the list, ask it directly.

Start the survey
What is a steel frame home?
A house whose structure is a steel frame, usually rigid frames of welded steel bolted to a concrete foundation, with steel purlins and girts. It is finished inside like any other house and is permitted under the same residential code.
Are steel home kits available for New Jersey?
Yes. A steel home kit is the frame, secondary framing, panels and drawings for the shell. For New Jersey it has to be sized to the snow and wind for your exact site and backed by a set sealed by a New Jersey-licensed architect or professional engineer.
How deep are the footings for a steel frame?
Below the frost depth New Jersey sets in its residential code: 36 inches in Mercer and Middlesex counties and every county to the north, and 30 inches in Monmouth and Burlington counties and every county to the south. The sealed drawings may call for deeper or larger footings for the frame loads.
Is steel exempt from the 4,800 square foot limit?
Not automatically. New Jersey's residential code limits unsprinklered wood-framed houses to 4,800 square feet per floor, and other construction types get limits based on how their building elements are rated. The design professional who seals the set classifies the building with the construction office.
Does a steel frame need seismic design in New Jersey?
No, for a house. New Jersey's edition of the residential code exempts detached one- and two-family dwellings from its seismic requirements. Snow and wind govern the frame.
Is steel better than wood posts?
Steel gives wider clear spans and is not food for termites, which New Jersey's code rates as a moderate to heavy risk statewide. Post-frame is often cheaper on moderate spans. We price both when either suits the plan.
Do you build commercial metal buildings?
This page is about steel frame homes. Our work is new barndominium homes, including homes with a shop or garage under the same roof.
Who erects the frame?
We can, or you can erect a kit yourself with the erection drawings. Either way the construction office inspects the footings and the frame at the stages listed on the permit.
