You have built houses, additions, maybe small local projects, and you keep seeing the same line on US roles: commercial experience required. It is one of the most common reasons a capable LATAM architect scrolls past a listing. The mistake is assuming that commercial vs residential architecture is a question of scale. It is not. Commercial is a different world, and understanding that world is what studios are really asking for.
A bigger house is still a house. The line between commercial and residential is drawn by which code governs the building. Residential, meaning one and two-family homes and small townhouses, falls under the International Residential Code. Everything else falls under the International Building Code, the world we cover in US building codes for internationally trained architects.
The detail that surprises people is where multifamily lands. A building with three or more units is governed by commercial code, no matter how residential it feels. So a four-unit walk-up is commercial work, and naming it that way matters.
Commercial is not harder for the sake of it. It carries a heavier set of requirements because the building serves the public, and that changes the work at every stage.
| Dimension | Residential (IRC) | Commercial (IBC) |
|---|---|---|
| Governing code | IRC, largely prescriptive | IBC, engineered |
| Life safety | Simple, few occupants | Occupancy classification, egress, fire ratings |
| Accessibility | Limited | ADA and ICC A117.1 throughout |
| Coordination | Small team | Structural, MEP, and civil, many specialists |
| Documentation | Lighter | Heavy: submittals, RFIs, schedules, as-builts |
| Permitting | Faster | Longer, with multiple reviewers |
Read that table as a skills list. Occupancy classification, ADA, MEP coordination, and a much heavier documentation load are exactly the competencies a residential-only background does not build on its own.
Commercial is a broad label. If you have touched any of these, even locally, you have commercial experience you can name and describe.
Commercial is where the documentation and coordination load is heaviest, which is exactly why studios most want to hand it off, the pattern we describe in construction documents sets. A studio needs people who can carry IBC-level documentation, ADA, occupancy, and MEP coordination without hand-holding.
It also shows in the openings. The clear majority of remote architecture roles are commercial, retail, multifamily, office, and mixed-use, not custom homes. Commercial experience simply opens more doors.
Here is the honest part. Architects moving from residential into commercial almost always underestimate three things: the documentation load, the depth of coordination with other disciplines, and the intensity of the code work.
The shift is a mindset, not a size upgrade. You stop thinking about a single client's taste and start thinking about occupancy, egress, accessibility, and a paper trail that is itself part of the deliverable.
You can close this gap deliberately, and most of it does not require a US project to start.
We connect pre-vetted LATAM architects, drafters, and modelers with AEC firms in the US and Canada, and we handle the legal side, payments, and compliance so you can focus on the work. Because most of our client projects are commercial, growing that experience with us compounds. If that fits you, explore remote roles for architects and drafters.
Anything governed by the International Building Code: retail, offices, multifamily with three or more units, hospitality, healthcare, institutional, and industrial. Multifamily counts as commercial even when it feels residential.
Commercial carries stricter codes, ADA requirements, multidisciplinary coordination, and a much heavier documentation load. Studios want people who can handle all of that reliably, since it is the work they most often send out.
Yes, but treat it as a mindset shift, not a size upgrade. Learn the IBC, ADA, and occupancy basics, get comfortable with heavier documentation and coordination, and reframe any multifamily or small commercial work you have already done.
The IBC governs commercial and larger multifamily buildings with stricter fire, structural, accessibility, and documentation requirements. The IRC governs one and two-family homes and small townhouses, and is largely prescriptive.
Yes. A building with three or more units falls under commercial code regardless of how residential it feels, so multifamily work is genuine commercial experience.
Reframe the relevant projects you do have, build real depth in the code and documentation side, and add one commercial-type project to your portfolio, even a self-directed one.
