FAQ
Architect Requirement Questions
Do I need an architect for an ADU?
It depends on your state. Some states (including California, Washington, Oregon, and Colorado) require a licensed architect or engineer stamp on ADU permit drawings. Others (including Texas, Florida, and Arizona) generally do not for standard single-family residential projects. Use the quiz above for a state-specific answer, and always confirm with your local building department before submitting.
Do I need an architect for a garage conversion?
Usually the same rule as your state's general residential stamp requirement applies, unless the conversion involves structural changes like removing a load-bearing wall, adding a second story, or new foundation work — those typically require at least a structural engineer's review regardless of your state's general exemption.
What is a licensed architect requirement?
A licensed architect (or engineer) requirement means your jurisdiction requires a professional with an active state license to review and stamp your construction drawings before the building department will accept them for permit. It is a state-by-state (and sometimes city-by-city) rule, not a national standard.
Can I submit drawings without an architect stamp if my state requires one?
No — if your state requires a stamp, the building department will reject an unstamped submission. Build With A Plan's Standard and Premium packages include coordinated stamp review through a network of licensed professionals in stamp-required states, at a fraction of what a full-service architectural firm charges for the same document set.
Does a bigger ADU always need an architect?
Size alone does not usually trigger the stamp requirement — that is set by your state's general rule. But going over your state's maximum allowable ADU square footage is a separate zoning issue that can affect whether your project is eligible at all, independent of the stamp question.
