The Short Answer
Yes — AI can generate a site plan from an address in seconds. It can show property lines, existing structures, and even generate setbacks and contours. But AI cannot replace a licensed surveyor for legal boundary work, and most AI-generated site plans are not legally certified.
What AI Site Plan Generators Can Do
AI-powered site plan tools like our site plan generator can:
- Enter an address — pull property data from public records
- Show property lines — display boundaries with bearings and distances
- Add proposed structures — place sheds, decks, pools, ADUs, and more
- Generate setbacks — show required distances from property lines
- Generate contours — display topography from LIDAR data
- Export a PDF — produce a clean, permit-ready drawing
These tools are designed for small residential projects where the city allows homeowner- or contractor-prepared drawings.
What AI Site Plan Generators Cannot Do
1. Replace a Licensed Surveyor
AI-generated property lines are based on public records and GIS data — not on physical site measurements. If you need a legal boundary survey for a dispute or new construction, you need a licensed surveyor.
2. Provide a Stamped Plan
Most jurisdictions require a professional seal for certain projects — new construction, commercial work, or projects in floodplains. AI tools don't provide stamps.
3. Guarantee Permit Approval
AI tools can generate a site plan, but the final decision rests with your local building department. Always check your city's requirements.
4. Handle Complex Sites
If your property has unusual boundaries, steep slopes, floodplain issues, or complex easements, AI tools may not have enough data to produce an accurate plan.

FAQ
Q: Is an AI site plan acceptable for a permit?
A: In many cities, yes — for small residential projects. Always check with your local building department.
Q: Can AI replace a surveyor?
A: No. AI site plans are based on public records and GIS data. They are not legal surveys.
Q: How accurate is an AI site plan?
A: Accuracy depends on the quality of the underlying data. In counties with good GIS data, property lines are generally accurate. In counties with poor data, you may need to verify with local records.
Q: Do I need a stamp on my site plan?
A: Only if your city requires one. Most small residential projects don't need a stamp.
Q: What if my AI site plan gets rejected?
A: You can revise it yourself using our site plan creator, or order a done-for-you plan from SitePlans.us (non-certified, permit-ready only).
