Commercial Solar Permit Design Services — Scoped to Your Project
Permit Design prepares commercial solar permit plan sets and permit drawings for solar EPCs, installers, and roofing companies across all 50 US states. From a few kilowatts up to several hundred kilowatts — every plan set is NEC 2026-compliant, built to your AHJ’s specific requirements, with turnaround scoped to your project size and complexity.
We process 2,000–2,500 plan sets every month across residential and commercial projects. If your AHJ requests revisions, we handle them at no extra charge.
How It Works
1. Submit — Send us your project details via the order form: site address, aerial or site plan images, equipment model numbers, and system size. Takes under 5 minutes.
2. Draft — Our commercial permit design specialists prepare your complete plan set — site plan, roof or ground layout, single-line diagram, three-line diagram where required, structural calculations, and utility interconnection docs.
3. Deliver — Your AHJ-ready commercial plan set is delivered once complete — timeline confirmed with your custom quote based on project size and complexity. Revisions handled at no extra charge until your building department approves.
What’s Included in Every Commercial Solar Permit Plan Set
Cover Sheet: Project name, system capacity (kW/kWac), site address, designer credentials, adopted NEC edition, utility information, and AHJ contact details — formatted to commercial building department standards.
Site Plan: Scaled aerial site plan showing property boundaries, existing structures, utility entry points, fire department access routes, equipment pad locations, and full array-to-switchgear routing.
PV Array Layout: Commercial array layout with exact panel placement, inter-row spacing for shading clearance, roof zone setbacks per local fire code, and equipment locations for inverters, combiners, and disconnects.
Single-Line Diagram: Commercial electrical schematic from PV array through combiner boxes, inverters, and AC disconnect to utility interconnection point — NEC Article 690 and Article 705 compliant for your jurisdiction's adopted code edition.
Three-Line Diagram: Per-phase wiring diagram showing conductor sizing, conduit fill, overcurrent protection devices, metering configuration, and revenue-grade meter placement — required by most commercial AHJs and utilities for systems above 10kW.
Labels & Placards: Full NEC-required commercial labeling package — rapid shutdown placards, AC/DC disconnect identification, source circuit labels, utility interconnection signage, and system identification markers per adopted code edition.
Equipment Datasheets: Manufacturer spec sheets for every commercial-grade component — modules, string or central inverters, combiners, racking, monitoring systems, and battery storage where applicable.

FAQ SECTION:
Q1: How long does a commercial solar permit plan set take?
Turnaround depends on system size, AHJ requirements, and project complexity. We assess every commercial project individually and provide a timeline with your custom quote. Send us your project details and we’ll respond within 24 hours.
Q2: What size commercial solar projects do you cover?
We handle commercial permit plan sets from a few kilowatts up to several hundred kilowatts — rooftop, carport, and ground mount systems for any commercial or industrial AHJ across all 50 states.
Q3: Do commercial solar permit plan sets require a PE stamp?
Most commercial jurisdictions require engineer-stamped structural calculations and electrical drawings. Requirements vary by state and AHJ. We coordinate licensed PE stamps where required by your specific building department.
Q4: Is a three-line diagram required for commercial solar permits?
Most commercial AHJs and utilities require a three-line diagram in addition to the standard single-line. Every commercial plan set from Permit Design includes a three-line diagram as standard.
Q5: What NEC edition applies to commercial solar permit drawings?
We use the NEC edition adopted by your specific AHJ — NEC 2020, 2022, or 2026. Commercial projects also require compliance with NEC Article 705 for interconnected power production sources.
Q6: Do you handle utility interconnection drawings for commercial projects?
Yes. Every commercial plan set includes utility interconnection documentation formatted for your specific utility — SCE, PG&E, Oncor, Duke Energy, FPL, and 100+ others across all 50 states.
Q7: Which states do you serve for commercial solar permit design?
We serve EPCs, installers, and roofing companies across all 50 US states — from California CEC Title 24 to Texas NEC 2022, New Jersey UCC, Florida Building Code, and every other jurisdiction.
