PE Stamp Required for Commercial
We manage the complete process — drafting, engineering review, licensed PE stamp, and portal-ready PDF delivery. One team, one workflow.
Commercial permits require accurate parking layouts, ADA compliance, fire lane access, drainage notation, and a PE stamp. We prepare commercial site plans with full engineering review — formatted for your building department's portal.
A commercial site plan is a scaled, top-down drawing of a commercial property showing the building footprint, parking areas, access points, pedestrian routes, landscaping buffers, drainage, and all required code compliance elements — prepared for submission with a commercial building permit application.
Commercial site plans are held to a higher standard than residential. The building department evaluates occupancy classification, parking ratios, ADA accessibility, fire access, and stormwater compliance — all of which must be shown on the plan and reviewed by a licensed PE.

In virtually every US jurisdiction: commercial building permits require PE-stamped drawings. Submitting without a PE stamp means the application cannot be processed.
From single-suite tenant improvements to full commercial construction — every project prepared from scratch for your specific jurisdiction.
Site plan shows property footprint, parking, access, proposed interior changes visible on exterior (new entrance, storefront modification), fire lane, and compliance notes.

Federal ADA requirements apply to all commercial properties in all 50 states. We calculate and show the correct ADA parking for your specific project on every commercial plan.
Space dimensions: 8 ft wide + 5-ft access aisle minimum. Van spaces: 8 ft wide + 8-ft access aisle, or 11 ft wide + 5-ft aisle.
Van-accessible: 1 van-accessible space per every 6 accessible spaces (or fraction thereof).

In virtually every US jurisdiction, all commercial building permits require a PE-stamped site plan. The PE stamp means a licensed Professional Engineer has reviewed the drawings for code compliance, ADA accuracy, drainage, and engineering accuracy — and takes professional responsibility for the content.
Submitting a commercial permit application without a PE stamp means the application cannot be processed. It's not a recommendation — it's a requirement.
