ADU developers and custom-home builders waste 2–6 weeks and $4–12K per project on the first sketch — the part where 80% of plans are still rejected. ArchitectAI generates a code-aware, dimensioned schematic from a brief. Iterate before you ever pay an architect.
Between brief and first usable sketch — assuming the architect responds. ADU and custom builders pay this tax on every single project.
Just for schematic design. Sunk cost if the lot doesn't pencil. Builders eat this on every dead project.
Of first-pass sketches get scrapped or heavily redrawn. The work is iteration — but no one can afford to iterate at human speed.
Meanwhile, every state has legalized ADUs. Inventory is at a 40-year low. The country needs faster homes. The first 5% of every project is what's slowing us down.
Plain language: "60×120 lot in Austin, family of 4, two-car, $450K cap." Parser maps narrative to spatial constraints + zoning lookup.
Determines room count, adjacency graph, square-foot allocations. Honors locked rooms and must-keep adjacencies if you specify them.
Constraint-based packing onto the lot envelope. Iterates with daylight, egress, and circulation as cost terms.
Cross-references IRC 2021 + state amendments. Failed checks block export. Passing rules surface as annotations on the drawing.
Dimensioned plan with door swings, fixtures, room schedule, title block. Export DXF for your architect, PDF for your contractor.
Granny-flat operators run on volume — 12 to 40 builds a year, on tight margins, pre-existing site templates. They feel the schematic-design tax most acutely. Once we own that wedge, we expand into custom builders, then small-multifamily.
~150K permits/yr in CA, OR, WA. Highly templated. Repeat customer.
~55K starts/yr by small builders. Bespoke briefs, longer cycle, higher AOV.
Duplexes / fourplexes. Zoning reform unlocking inventory. Higher complexity.
Anyone can prompt a model to draw a floor plan. The hard part — the part that makes a plan actually buildable — is encoding building code as a constraint set the solver respects. We're 18 months into compiling it.
IRC 2021 base + the four most-adopted state amendments (CA, FL, NY, TX). Each rule is a constraint, not a prompt — failed checks block export.
49 states have legalized ADUs or upzoned single-family lots since 2021. Inventory unlocked, demand uncapped.
AIA reports a 14% gap in licensed residential architects. Firms reject small briefs. Builders need self-serve tooling.
Multi-step agentic reasoning over CAD geometry was impossible 18 months ago. Now it's a weekend prototype + a year of code-rule encoding.
Every plan was drafted by the same agentic pipeline you can run on your own brief. Schematic-quality, dimensioned, ready for an architect to take to construction documents.
“I watched my parents try to build an ADU in their backyard. Three architects ghosted them. The fourth charged $9,400 for sketches that ignored the setback. I built ArchitectAI because the first 5% of a project shouldn't be the part that kills it.”
