Do You Need an Architect to Submit Residential Plans?

One of the most common questions from homeowners, owner-builders, and designers is:

“Do I need an architect to submit these plans?”

The answer is: it depends.

In many cases, you can submit plans without a licensed architect—but there are important exceptions.

In this post, I’ll break down when an architect is required, when an engineer may be needed instead, and when you’re free to draw and submit plans yourself.

When an Architect Is NOT Required

In most U.S. states, you can submit residential plans without an architect if:

The project is a single-family home or duplex The home is not over 2 stories tall (3 in some states) The structure is conventional wood framing You are the property owner or licensed designer

These projects can often be submitted by:

Draftspeople Design professionals Civil engineers (in some cases) Owner-builders

Tip: Always confirm your state’s architectural practice laws—some, like California and Texas, have very specific language about what’s exempt from requiring an architect.

When an Architect Is Required

You’ll likely need a licensed architect if your project:

Exceeds 2 or 3 stories in height (depending on local code) Involves unconventional design or structural systems Includes mixed-use, commercial, or multi-family components Is in a city or district that requires an architect’s stamp

Also, some jurisdictions may require a licensed architect for:

Projects over a certain square footage (e.g., > 5,000 sq ft) Historical properties or design review districts Custom hillside designs or non-standard foundation work

What About Engineers?

You might not need an architect—but you may still need an engineer.

A structural engineer is often required when:

The project involves retaining walls, steel framing, or complex loads Local codes require engineered shear and lateral calcs You’re building in a high wind, snow, or seismic zone

In these cases, an engineer must provide:

Foundation plans Framing layouts Calculations and stamped drawings

Owner-Builders: Can You Submit Plans Yourself?

Yes, in many places you can design and submit your own plans as an owner-builder, especially if:

You live on the property You’re doing the work yourself or hiring licensed subs The project is small or straightforward

However, you’ll still need to meet all code, zoning, and documentation requirements—and the building department will not “go easy” just because you’re the homeowner.

Final Thoughts

You don’t always need an architect to submit residential plans—but you do need a plan set that meets code, includes the right documents, and is clearly drawn and coordinated.

Still unsure? A quick call to your building department can clarify whether your project qualifies for exemption from architectural stamping.
