WHO PLANDECODE IS FOR
You already have the drawings. You need to understand them.
PlanDecode is built for homeowners reviewing an existing architectural, structural, or permit plan-set PDF before contractor pricing, permit submittal, revisions, or construction.
Do not use it as an approval
PlanDecode is not a design generator, stamped review, structural certification, city plan check, or permit guarantee.
ONE REVIEW, FIVE DECISIONS
Know what the drawings say, what may be missing, and what to do next
PlanDecode does more than assign a score. Every concern includes drawing evidence, plain-English context, likely project impact, and a recommended owner or professional role.
Cost Clarity
Identify missing scope, quantity, material, and coordination information that can undermine early budgets.
Constructability
Review visible assemblies and details that may create field questions, change orders, or rework.
Drawing Quality
Find gaps and conflicts in dimensions, notes, detail callouts, and references across the plan set.
Code Risk
Surface visible issues that should be verified against the local jurisdiction and applicable California codes.
Permit Readiness
Organize likely plan-check questions and missing documentation before formal city review.
EVIDENCE, NOT A BLACK BOX
From a dense drawing set to a prioritized action list
The AI first creates a page-level fact record, then checks cross-sheet coordination, and only then prepares the final assessment.
- Printed sheet and original PDF page references
- Observed condition and why it matters
- Potential cost, construction, or permit impact
- Recommended resolution and professional responsibility
HOW COMPLETE-SET REVIEW WORKS
One plan set, three layers of understanding
PlanDecode keeps the full drawing context in view, checks related sheets together, and turns the evidence into decisions a homeowner can act on.
Every sheet enters the same project record
Plans, elevations, sections, structural sheets, and details are read as parts of one building.
BETTER QUESTIONS, EARLIER
Make the important decisions before they become change orders
PlanDecode organizes what is visible, what remains uncertain, and which professional should confirm it. You can move into pricing, permit review, or construction with a clearer conversation.
- 01
Before contractor pricing
Find missing scope, material, dimension, and coordination information that can make bids difficult to compare.
- 02
Before permit submittal
Collect likely plan-check questions and identify items that still need jurisdiction or licensed-professional verification.
- 03
Before work begins
Surface visible conflicts across plans, elevations, sections, and details while revisions are still easier to make.

QUESTIONS BEFORE YOU UPLOAD
What the free review can and cannot do
Does the AI review every page?
Yes. The plan set is processed in saved groups, followed by a cross-sheet coordination review and a final synthesis stage.
Is this a permit approval or structural certification?
No. It is an early pre-review for information organization and risk awareness. A licensed architect or engineer and the local authority having jurisdiction must make formal determinations.
How do I return to my report?
No account is required. We email a private link after submission. Keep it confidential because it grants access to the project workspace and report.
Can Cecilia Home help fix the issues?
Yes. The report can connect you to Cecilia Home's professional team for architectural design, structural engineering, permit submission, and correction support.
