Structural PE Stamp in Nashville, TN: Metro Codes Review and ePermits

By Jeremy Mills, CEO & Founder, Apex Grid Engineering — USAF Veteran. · Updated 2026-09-15

A structural PE stamp in Nashville means a licensed Tennessee PE has taken responsible charge — verifying calculations, foundation design against the geotechnical report, and lateral-system continuity — before sealing drawings reviewed by the Metro Codes Department through the ePermits portal.

Illustrative diagram of the professional engineer review and seal workflow: drawings are reviewed against a checklist, sealed by a licensed PE, and issued as a permit set.

The Metro Codes structural review path

Nashville's ePermits portal is the single intake for structural review across the consolidated government: application, sealed drawing upload, fee payment, reviewer assignment, correction cycles, and approval all live in one tracked system. Metro Codes' structural reviewers work from the adopted building code and expect the calculation package to reference the correct edition explicitly. Their comments tend to be specific and technical — a missing collector detail, a foundation detail that doesn't match the geotech report, a diaphragm nailing schedule that doesn't support the stated shear. We write our submittals for that level of reader: every calculation indexed to its drawing sheet, every assumption stated, every delegated-design item designated as a deferred submittal with criteria. Precision in, precision out.

Foundations, lateral systems, and what our review catches

Our responsible-charge review for Nashville structural work starts below grade: the geotechnical report's recommendations implemented in the foundation drawings, karst considerations addressed where the report flags them, and special-inspection requirements noted for foundation work. Above grade, we trace the complete load path — gravity framing sized for actual loads, a lateral system with continuous diaphragms, collectors, and shear walls or frames detailed for the adopted wind and seismic parameters, and connections designed for the forces they actually carry. We check that the drawings match the calculations member for member, and that nothing structural was left to 'field verify' without a defined verification plan. This is the engineering the seal certifies: a design that has been checked, corrected, and checked again before it ever reaches Metro Codes.

Nashville structural submittal checklist

A Nashville structural package is ready for ePermits when these items are verified. Metro Codes rewards submittals that read cleanly. • Jurisdiction confirmed within Metro Nashville/Davidson County (neighboring counties are separate AHJs) • Calculation package indexed to drawing sheets with the adopted code edition referenced • Foundation design implementing the geotechnical report, with karst considerations addressed • Continuous load path: diaphragms, collectors, and lateral elements fully detailed • Special inspections called out on the drawings where required • Deferred-design items designated as deferred submittals with design criteria • Existing-structure field verification completed for renovations before the PE seals

What else do project teams ask?

Which department reviews structural drawings in Nashville?
The Metro Codes Department, part of Nashville's consolidated metropolitan government covering the city and Davidson County together. Structural plan review is submitted through the city's ePermits online portal, which handles intake, fee payment, reviewer comments, and resubmittals in one tracked workflow. Because the government is consolidated, there is generally no separate city-versus-county question inside Davidson County — but projects near the county line still need their jurisdiction confirmed, since neighboring counties run their own building departments with their own processes.
Why do Nashville reviewers focus on foundations and geotechnical reports?
Middle Tennessee's limestone geology, including karst features like sinkholes and voids, makes foundation performance a genuine risk that reviewers take seriously. They expect the structural design to be visibly tied to a geotechnical investigation: bearing values, pier or footing depths, and any karst mitigation the report recommends. Our pre-seal review verifies that the geotech recommendations were implemented in the drawings — the right foundation type at the right depth with the right details — rather than merely referenced. A foundation design that floats free of its geotechnical report is one of the fastest ways to earn a Nashville correction notice.
What does the PE's responsible-charge review cover on a Nashville renovation?
Renovations get an existing-conditions review on top of the new-work design. We verify the capacity of the existing framing for new loads, check how new elements connect into old construction, and require field verification of concealed conditions before sealing — Nashville's older buildings often differ from their record drawings, and assuming the drawings are accurate is how structural failures start. Where the existing structure cannot be fully verified, we design conservatively and document the assumptions. The seal certifies that this investigation happened, not just that the new drawings look complete.
How does the ePermits correction process work?
Reviewer comments come back through ePermits as a correction list, and resubmittals must address every item with clouded drawing revisions and written responses. The portal keeps the full history, so reviewers can see exactly what changed and what didn't. We answer each comment individually — agreeing and showing the revision, or respectfully explaining with code references where we believe the original design complies. Vague or partial responses generate second-round comments, so we treat the response letter as carefully as the drawings themselves.
