Solar Permit Design

Solar permit design is the drawing work a permit application depends on — the site plan, roof plan, single-line diagram, structural details and label schedule, drawn to the code cycle and amendments the reviewing jurisdiction has actually adopted. Avila Solar Drafting produces that package for installers, EPC firms, engineering firms and architects, in 2–3 business days from a complete intake. We draw the plans. You file the permit.

Key takeaways

• We are a design firm, not a permit runner. We don’t pull permits, file applications or act as an expediter — the AHJ account and contractor licensing stay with you.
• Every set is drawn to the reviewing jurisdiction’s adopted NEC and I-code editions, confirmed per order rather than assumed from a national template.
• 2–3 business days standard, 1–2 for Fast Roof, 1 business day when Fast Roof is paired with a Roof Order or EagleView XML.
• Free revisions for 6 months — including responses to plan review comments, at no new order.
• PE stamps are handled in-house where a jurisdiction triggers one.

What we do, and what stays with you

This distinction matters, so it’s worth being blunt about it.

We do: produce the stamped-where-required drawing set your permit application needs, drawn to the adopted code cycle, the AHJ’s submittal format, and the serving utility’s interconnection requirements. We respond to plan review comments and revise the set under the revision window.

You do: file the application, hold the AHJ account, carry the contractor licensing, and own the relationship with the reviewer and the inspector. Permit filing is licensed work tied to the contractor of record, and it belongs on your side of the line.

If a vendor tells you they’ll “handle your permits,” ask which of those two lists they mean. Most of the time they mean the first one.

What’s in a permit design package

• Cover sheet and code summary naming the adopted NEC and I-code editions the set was drawn to, project data and the sheet index
• Site plan — property lines, structures, setbacks, equipment locations and the utility service point
• Roof plan — array layout by plane, module count and orientation, attachment spacing and fire access pathways
• Electrical single-line diagram — conductor and OCPD sizing, grounding, interconnection method and the AC disconnect in the location the utility requires
• Structural details and calculations where the roof condition or jurisdiction triggers them
• Placard and labeling schedule matching the adopted cycle — not a generic label set

What’s in a plan set walks through each sheet in detail. For the deliverable and product lines themselves, see solar plan sets.

Why the jurisdiction changes the drawing

Permit design is jurisdiction-specific work, and that is the whole reason it can’t be templated. Three things move independently:

The adopted code cycle. Cities adopt the NEC and the I-codes on their own ordinances and schedules, so neighbouring jurisdictions routinely sit on different editions. Label schedules and disconnect requirements change between cycles, which is why a set that cleared one city is not automatically drawn for the next one.

The AHJ’s submittal format. Some jurisdictions publish information bulletins with explicit triggers for engineered drawings; others don’t publish anything and the requirement surfaces as a plan review comment.

The serving utility. Interconnection is a separate track from the building permit, and the utility’s disconnect and metering rules land directly on the site plan and the single-line diagram.

We confirm all three before drafting. Why permits get rejected and permitting requirements installers miss cover the failure patterns in more depth.

How it works

1. Send the site data — survey, equipment list with model numbers, existing service and panel details, roof measurements. A Roof Order or EagleView XML speeds this up more than anything else.
2. We confirm the jurisdiction — adopted cycle, amendments, submittal route and serving utility.
3. We draft the set and run an independent senior-designer review before it reaches you.
4. You submit — under your licensing, to your AHJ account.
5. Comments come back to us — send the letter and we revise inside the 6-month window, no new order.

Turnaround and revisions

Standard sets ship in 2–3 business days from a complete intake. Fast Roof runs 1–2 business days, and 1 business day when paired with a Roof Order or EagleView XML. Revisions are free for 6 months from the order date.

We guarantee accurate solar plan sets, drawn to the electrical and building code requirements of your specific jurisdiction and designed to pass first-time review. What we don’t do is promise an approval — the AHJ makes that call. What we control is whether the set gives them a reason to say no.

Where we work

We draw for jurisdictions nationwide from our Beaverton, Oregon office. Four exclusions, stated up front so nobody wastes a call: we do not take projects in APS or SRP territory in Arizona, the City of Peoria, AZ, the City of Phoenix, AZ, or Los Angeles County (LABD), California.

State and metro pages carry the local detail — adopted cycles, utility rules and stamp triggers. Start with Texas solar plan sets.

What drives the cost

Roof complexity and plane count, whether a main panel upgrade or line-side tap is involved, whether energy storage is in scope, roof versus ground mount, whether a PE stamp is triggered, and how complete the site data is at intake. Current figures are on the solar plan sets page. Where a stamp is required, our engineering stamps service handles it without restarting your schedule.

Send the jurisdiction, the utility and the site data. You get back a set drawn to that AHJ’s adopted cycle and that utility’s interconnection requirements, in 2–3 business days, with six months of free revisions behind it.
