PE Stamped Drawings: What They Are, What They Include, and When You Need Them

“PE stamped drawings” is the term building departments use when they require licensed engineer-reviewed engineering documents. At $15.12 CPC, it’s one of the highest commercial-value keywords in the site plan and permit space — because the people searching for it are ready to order.

What Are PE Stamped Drawings?

PE stamped drawings are engineering documents that a licensed Professional Engineer has reviewed, approved, signed, and sealed with their official state stamp.

The term covers any drawing type that a PE has stamped:

• Site plans
• Structural drawings
• Grading and drainage plans
• Foundation plans
• Retaining wall designs
• MEP (mechanical, electrical, plumbing) engineering drawings
• Calculations packages

The key characteristic is the PE’s formal certification. A drawing becomes “PE stamped” when the licensed engineer applies their seal.

What Must Appear on PE Stamped Drawings?

Every jurisdiction has specific requirements, but all PE stamped drawings must include:

On the stamp itself:

• PE’s full legal name
• State PE license number
• State designation
• Engineering discipline (Civil, Structural, Mechanical, etc.)
• PE’s signature (wet or digital)
• Date of signing
• Official state seal

On the drawing itself:

• Project name and location
• Sheet title and number
• Engineering notes referencing applicable codes (IBC, state building code, ASCE 7, etc.)
• All dimensions and labels supporting engineering calculations
• Revision block with revision history

Types of PE Stamped Drawings

PE Stamped Site Plans

For commercial permits, most US jurisdictions require the site plan itself to be PE stamped. The PE reviews the site plan for: setback compliance with engineering implications, drainage flow and impervious surface, utility connections, ADA parking compliance, and fire access lane geometry.

Commercial Site Plans for Permits

PE Stamped Structural Drawings

For structural work — load-bearing wall removals, new beam installations, additions, second-story builds, retaining walls. The structural PE’s stamp certifies that:

• Member sizes (beams, columns, joists) are adequate for design loads
• Connections between members are properly detailed
• Foundation is adequate for the structural loads
• The design complies with IBC structural requirements and ASCE 7 load standards

PE Stamped Grading and Drainage Plans

For commercial sites, subdivisions, and residential projects in flood zones or with significant earthwork. The civil PE’s stamp certifies that:

• Drainage calculations are correct
• Stormwater runoff from the site meets discharge requirements
• Erosion control measures are adequate
• Finished grades drain properly

PE Stamped Calculations

Engineering calculations submitted for permit review — retaining wall design calculations, beam sizing calculations, foundation bearing calculations, drainage volume calculations, structural connection design packages.

PE stamped calculations are a separate deliverable from stamped drawings. Some permit applications require both.

What Makes PE Stamped Drawings Different From Unstamped Drawings?

Minimum Information Required on PE Stamped Drawings

Every PE stamped drawing set should include at minimum:

• Project address and legal description
• Sheet index identifying all drawing sheets
• General notes citing applicable codes: IBC/CBC edition, ASCE 7 edition, local amendments
• Design loads: dead loads, live loads, wind, seismic zone
• Material specifications: concrete strength (f’c), steel grade (Fy), lumber species and grade
• Geotechnical reference: site class for seismic, allowable bearing pressure if foundation design is included
• PE stamp on every sheet with engineering content
