Solar permitting for installers & EPCs

Stamped permit sets. Permit-ready 6 days from survey.

Structural and electrical drawings, sealed by a licensed professional engineer, built from a real on-site survey rather than a satellite guess. Submit once. Stop losing install dates to plan-check corrections.

Permit sets are quoted per project.

15 minutes, no deck. Tell us your volume and your AHJs.

Sealed by a licensed professional engineer

Your set arrives stamped and sealed, ready for submission — not a draft your own engineer still has to review, price and sign. We carry PE licensure in every state we serve, and we will tell you plainly on the first call if your jurisdiction is one we don’t cover.

Plan check is where install dates go to die

A rejected permit doesn’t cost you a week. It costs you a resubmittal queue, a rescheduled crew, and a customer who now has a reason to reconsider.

1

Corrections from missing field data

Sets drawn from aerial imagery miss the service panel rating, the bus bar, the actual rafter spacing. Plan check finds it, you don’t.

2

Resubmittal queues

Getting back in line is rarely the same week. One correction can push an install a month in a busy AHJ.

3

Engineering bottlenecks

If your set still needs a stamp after it’s drawn, you’re waiting on a second vendor’s calendar before you can even submit.

What’s in the set

Built from measured field data captured on site — the roof and the electrical in a single visit.

Structural

  • Roof plan with array layout, setbacks and fire pathways
  • Rafter/truss detail — species, size, spacing, span
  • Attachment and flashing detail
  • Load calculations for the specific structure
  • Located penetrations and obstructions — measured, not estimated

Electrical

  • Single-line diagram
  • Service panel detail — rating, bus bar, main breaker
  • Interconnection method and point of connection
  • Conductor sizing, OCPD and conduit routing
  • Placards and labelling per code

How it works

You are involved at the start and at submission. Not in between.

1

Send the address

Batch a week at a time if you like. No per-site scoping call.

2

We survey on site

Roof, structure and electrical captured in one visit by a technician who is actually there.

3

Stamped set 6 days after survey

Sealed, submission-ready, and drawn against the AHJ’s requirements — not a generic template.

Pricing

Permit sets are quoted per engagement. Scope varies too much between one residential roof and a multi-AHJ portfolio for a headline number to mean anything — so you get a real one on the first call instead of a “starting at” you can’t plan against.

  • Quoted on the first call — bring your monthly volume, your AHJs and typical system size
  • On-site survey available, if you need the field capture as well
  • Permit-ready in 6 days from survey, whatever the set is priced at
  • Batch submission — send a week of addresses at once

Seven years. Fifty thousand projects.

We have already met the edge case that is about to cost you an install date — in your AHJ, probably more than once.

Survey data approved by

Residential financing companies and third-party ownership (TPO) providers.

Roof, structural and electrical documentation for installer, third-party ownership (TPO) and financing teams. Confirm the required capture brief for each program before the visit.

From solar site survey to permit review

A permit package needs consistent field inputs and a clear project scope. The authority having jurisdiction and the utility have their own review requirements; a finished plan set is one handoff in that process.

Field record first

Roof dimensions, framing evidence and service equipment records should describe the same proposed installation. Resolve missing labels, unclear spans and placement questions before the package is submitted.

Design and engineering

Confirm the selected equipment, layout and structural and electrical scope. Our site survey supplies field inputs; the design record turns those inputs into the proposed system.

Review and closeout

Track jurisdiction comments and the revised drawing set together. After installation, inspection and utility requirements still apply; permit preparation is distinct from permission to operate.

Reference: DOE permitting and inspection guidance.

Solar permitting questions

Is a solar permit the same as utility permission to operate?

No. Local permitting and inspection address the installation under jurisdiction requirements. Utility interconnection and permission to operate are separate steps. Confirm both paths with the project’s jurisdiction and utility.

What field data supports a solar permit package?

The package uses the measured roof layout, structural information, existing service equipment record and proposed equipment locations. Required documents and review details vary by jurisdiction and project.

Does permit-ready mean the jurisdiction has approved the project?

No. Permit-ready describes the prepared package. Approval depends on the jurisdiction’s review, any required corrections and the applicable submission process; it is not guaranteed by package completion.

What helps avoid a second field visit during plan review?

Give the survey team the intended equipment and project scope, and confirm the required field record with design before the visit. Clearly flag missing measurements or labels so they can be resolved before submission.

Local solar permit requirements start with the address

Identify the actual city or county authority, applicable code edition, serving utility and required professional review before choosing a submission path. A survey supplies site evidence; the permit and utility permission to operate are separate approvals.

How to get a solar permit in Houston explains the City application, engineering evidence, CenterPoint PTO and current incentive checks with official sources. Browse other communities for geographic planning context; local requirements still need address-specific verification.

Tell us your AHJs. We’ll tell you if we’re a fit.

Fifteen minutes, no deck. Give us your monthly volume and the jurisdictions you submit into, and you’ll get a straight answer — including “not us” if that’s the truth.
