Non certified site plans for permits in USA are commonly used for residential permit applications that do not require engineering certification or a surveyor seal. Many cities and counties accept these plans for fences, pools, sheds, patios, and simple home additions.
I’m Engineer Wasim. This article explains exactly what a non-certified site plan is, when it’s accepted, when it isn’t, and how to know which type your permit requires.
What Is a Non-Certified Site Plan?
A non-certified site plan is a scaled property drawing prepared by a professional drafter — but not signed, sealed, or certified by a licensed surveyor or Professional Engineer.
It contains all the same basic elements as any permit site plan:
- Property boundaries and dimensions
- Existing structures
- Proposed project location
- Setbacks
- Scale, north arrow, title block
- All required permit notes
The only difference from a certified or PE-stamped plan is the absence of a professional license stamp on the document.
This is the type of site plan that Site Plans Online USA prepares for the majority of our residential clients — and it’s accepted by most city and county building departments for straightforward residential permit projects.
When Is a Non-Certified Site Plan Accepted?
A non-certified site plan is accepted by most jurisdictions for:
- Pool permits (residential)
- Fence permits
- Shed and accessory structure permits
- Deck and patio permits
- Driveway permits
- Basic home additions
- ADU site plans (in most jurisdictions)
- Simple commercial tenant improvements in some areas
These projects are low risk, straightforward in scope, and don’t require engineering analysis. The building department is evaluating setback compliance and basic site layout — not structural engineering.
Most cities and counties across the United States routinely accept non-certified site plans for this category of work.
When Is a Non-Certified Site Plan Not Enough?
A non-certified site plan will not satisfy your building department when:
- The project requires structural engineering — retaining walls, foundation changes, structural additions
- It is a commercial permit — most jurisdictions require PE-stamped plans for all commercial work
- It is new home construction — PE or architect stamp typically required for full building permits
- The building department specifically requests it — some jurisdictions require all site plans to be PE-stamped, even for simple residential work
- The property is in a CCCL or high-hazard zone — coastal construction or flood zone work may require certified drawings
- The permit comments specifically mention “engineer review required”
Non-Certified Site Plan vs. Certified Survey
A non-certified site plan is not the same as a certified survey.
A certified survey is prepared by a licensed land surveyor and legally certifies the exact location of your property boundaries. It carries the surveyor’s stamp and license number.
A non-certified site plan is prepared from GIS data and parcel records. It does not legally certify the boundaries, but it provides the building department with what they need to review your permit — the property layout, structure locations, setbacks, and project dimensions.
For most residential permits, a survey is not required. We use verified GIS data that’s accurate enough for permit submission. If you have a survey, we incorporate it into the plan.
Non-Certified Site Plan vs. PE-Stamped Plan
A PE-stamped plan has been reviewed by a licensed Professional Engineer and bears their seal, signature, and license number. The PE takes professional responsibility for the engineering judgments in the drawing.
A non-certified site plan is prepared by a drafter without engineering certification.
For most residential projects, engineering certification isn’t what the city is asking for. They want accurate setback information and a scaled drawing. For commercial projects, drainage plans, and structural work, the PE stamp is required.

How to Know Which Type You Need
The fastest way to find out: read your permit application checklist or correction notice carefully.
- If it says “site plan” or “plot plan” without specifying professional certification a non-certified plan is likely fine.
- If it says “PE-stamped,” “engineer-reviewed,” “sealed,” or “licensed professional required” you need a PE stamp.
- If it says “certified survey” you need a licensed surveyor.
