The Case for Outsourcing Solar Permit Design
Most solar installers start producing permit plan sets in-house. As project volume scales, the cracks appear. Here's what changes when you outsource to a dedicated solar permit design service.
The In-House Problem
The Outsourcing Solution
In-House vs Permit Design — How It Stacks Up
A direct comparison across the factors that matter most to high-volume solar installers and EPCs.
| Factor | ⚠️ In-House | ✅ Permit Design |
|---|---|---|
| Cost model | Fixed salary — you pay whether busy or slow | Per-project — cost scales with revenue |
| Residential turnaround | Variable — slower at peak season | 24–48 hours — every project, every time |
| Commercial turnaround | Depends on staff availability | Scoped to project — confirmed with quote |
| AHJ knowledge | Limited to markets already worked | All 50 states — 3,000+ AHJs covered |
| NEC code tracking | Manual — easy to miss state adoptions | Automatic — correct edition every time |
| Revision policy | Internal cost and staff time | Free unlimited revisions until AHJ approval |
| Multi-state expansion | New learning curve per state | Instant — every state already covered |
| Scalability | Requires new hires to scale | 1–500 plan sets/month, no overhead change |
| PE stamps | Requires licensed PE per state | Coordinated where required by AHJ |
