Design Drawings
Elevations and scaled drawings showing each letter, spacing, and overall sign placement relative to building features; include dimensions and material callouts so fabricators and reviewers can verify compliance.
A complete Signage Channel Letters package reduces permit delays, prevents fabrication errors, and documents compliance with electrical and local sign codes. When combined with a verified audit trail and e-signatures, it helps establish who approved specifications and when, supporting project timelines and liability management under ESIGN (15 U.S.C. ch. 96) and state UETA frameworks.
The Signage Channel Letters package is used by teams across design, permitting, fabrication, and property management to coordinate approvals and installation.
Clear role definitions and a single authoritative document reduce rework, expedite review cycles, and create an auditable approval trail for future reference.
Owner or authorized representative. Must confirm permission for exterior signage, approve final design and location, and accept responsibility for compliance with lease and local code; their signature authorizes installation or third-party permits.
Project manager or authorized sign company officer. Signs to confirm fabrication and installation responsibility, certify electrical conformity, and commit to meeting inspection and safety requirements on behalf of the installer.

Choose a platform that accepts PDF plans, supports authenticated e-signatures, and integrates with your project tools.
Ensure the platform preserves an audit trail and retains signed records in standard formats so municipal reviewers and internal teams can reproduce the signed package if required.
Elevations and scaled drawings showing each letter, spacing, and overall sign placement relative to building features; include dimensions and material callouts so fabricators and reviewers can verify compliance.
Transformer location, wiring diagram, voltage, and power calculations that demonstrate code compliance and allow inspectors to match field installations to the permit application.
Attachment methods, anchor specifications, substrate notes, and any required structural reinforcement to ensure safe installation and reduce inspection rejections.
High-resolution site photos showing the façade, surrounding context, and proposed sign location to help reviewers assess visibility, obstructions, and required clearances.
Manufacturer data sheets, finishes, paint codes, and lighting type (LED, neon, etc.) so planners can review durability, safety, and neighborhood compatibility.
Signed owner authorization, permit application forms, and any HOA or landlord approvals necessary to demonstrate legal permission for installation.
Export the approved package as a flattened PDF (PDF/A recommended) combining drawings, photos, and signed pages; include bookmarks for each section to simplify reviewer navigation.
Include editable source files (DWG, layered PDF) for fabrication use, clearly labeled with revision numbers and dates to prevent out-of-date production.
Attach a machine-readable certificate of completion showing signer identities, timestamps, and IP addresses to prove who approved the package and when.
Add manufacturer cut sheets, ballast/transformer specs, and structural engineer letters where required; name attachments consistently to match permit checklist items.
2–8 weeks depending on jurisdiction and application completeness
Schedule 1–3 weeks after permit issuance for inspection availability
2–6 weeks based on complexity and shop backlog
Coordinate contractors and crane or lift availability 1–3 weeks in advance
Municipal correction cycles typically allow 7–30 days for resubmission
Finalize drawings and specs and prepare the signed package for submission.
Municipal reviewers check code compliance and request corrections if necessary.
Fabricator produces letters to approved specifications following signed authorization.
Install letters and complete electrical and structural inspections for final sign-off.
