A homeowner in Portland wanted to add a deck. She paid $385 for a hand-drawn site plan, waited eleven days, and got back a drawing with the wrong setback line. Two and a half weeks. Four hundred dollars. One deck.
In 2026, she could have typed her address into an AI site plan generator and had a scaled, editable site plan in under a minute.
What an AI Site Plan Generator Actually Does
You give it one input — a US street address, or your lot's Assessor's Parcel Number (APN) — and it gives you back a scaled, overhead drawing of the property. Lot lines. Setbacks. Existing structures. Driveways. Hardscape. All to scale, all editable, all in under sixty seconds.
The generator doesn't guess. It reads:
- Parcel data — county assessor records with exact lot boundaries, dimensions, zoning class, and APN
- Aerial imagery — refreshed 1–4 times per year for most US properties
- Topographic data — grade, slope, and elevation contours from county GIS
- Setback rules — pulled from local zoning and drawn on the plan automatically
How It Works (Without the Jargon)
When you enter an address, the system queries county parcel APIs and GIS layers. The parcel polygon becomes the lot boundary. The aerial imagery goes through AI recognition to identify existing structures, driveways, and hardscape. Setback rules for the zoning class get pulled from municipal code databases.
The result: a coherent, scaled drawing that reflects the actual property — not a generic template.
IQ Agents handle the research. You handle the project.

3D site context arrived. InQI added 3D viewers powered by ESRI terrain data. Type your address, rotate the property in 3D, see the slope and relationship to neighboring properties. Useful for drainage discussions, shadow studies, and client presentations.
The editing got serious. Objects snap-align to property lines. Dimensions edit inline. Version history works. Export to PDF, DXF, or SVG without leaving the page.
How It Compares to a Human Drafter
Where AI clearly wins: speed (60 seconds vs. a week), cost (a fraction of $89–$2,000 drafter pricing), iteration speed (run dozens of layout scenarios), and data freshness (pulls the latest aerial and parcel data automatically).
Where you still want a human: when your county requires a stamped, wet-seal survey; for properties with unusual geometry or significant errors in the parcel record; and for full construction document sets.
