Solar Permitting in Portland & Oregon City: A Homeowner’s Guide to the Process

• It’s Not Just One Permit: You typically need both a Structural Building Permit (for the roof) and an Electrical Permit (for the wiring).
• Jurisdiction Matters: “Portland” is a broad term. Rules differ depending on if you are in the City of Portland , Oregon City , Lake Oswego , or unincorporated Clackamas County .
• The Utility Handshake: Getting the permit is only half the battle; we also have to file an Interconnection Agreement with PGE for Net Metering.
• HOA Rights: Good news—Oregon law protects your right to generate energy. HOAs cannot unreasonably ban solar panels.
• We Do The Paperwork: The best part? Energy Solutions manages this entire process for you. You don’t need to stand in line at the permit office.

Excitement is high. You’ve signed the proposal, you’ve picked your panels, and you’re ready to start saving money.

Then… silence.

For a few weeks, it seems like nothing is happening. But behind the scenes, our office is buzzing. We are navigating the bureaucratic maze of the Portland Metro area to ensure your system is legal, safe, and code-compliant.

As Oregon City’s trusted solar experts, we believe transparency is key. While we handle all the heavy lifting, we want you to know exactly what is happening with your project. Here is the step-by-step journey of a solar permit.

The first thing we determine is: Who actually owns your roof?

If your mailing address says “Portland,” you might actually be in unincorporated Multnomah County. If you live in Clackamas , you might be under the jurisdiction of Oregon City , Happy Valley , or the county itself.

Each jurisdiction has different snow load requirements, wind ratings, and setback rules.

• City of Portland (BDS): Has a streamlined “ Solar Prescriptive Path ” for simple roofs, but strict rules for historic districts.
• Clackamas County: Often requires detailed structural engineering for older homes to prove they can hold the weight.

Before we apply, we have to prove it works. Our engineers draw up a “line diagram” and a structural analysis.

We calculate:

1. Dead Load: The weight of the panels themselves (approx. 3 lbs per sq. ft.).
2. Live Load: The weight of a worker standing on them.
3. Environmental Load: The weight of a potential February ice storm or a wind gust coming down the Columbia Gorge.

We submit the packet to the building department.

• The Wait Time: In a perfect world, this takes 1-2 weeks. In reality, during the summer rush, some building departments can take 4-6 weeks to review plans.
• The Corrections: Sometimes, a plan reviewer asks for a change. “Add a sticker here” or “Clarify the rafter spacing there.” We handle these revisions immediately.

While the city looks at the structure , we also have to talk to PGE (Portland General Electric) about the electricity.

We file a Net Metering Application . This tells PGE that you are about to become a power plant. They check to make sure the transformer on your street can handle the extra energy you’ll be sending back. It is rare, but sometimes they require upgrades to their equipment before we can connect.

Once we have the “Green Light” (the physical permit card), we install your system. But we aren’t done yet.

We have to schedule two main inspections:

1. The Structural Inspection: The city inspector checks the racking to ensure lag bolts are hitting the rafters and the roof is watertight.
2. The Electrical Inspection: They check the grounding, the wire sizing, and the safety labels.

This is the final hurdle. Once the city signs off, we send that proof to PGE.

PGE then installs a Bi-Directional Meter (one that can spin backward) and issues a letter called “Permission to Operate.”

Only then can you flip the switch. Turning the system on before PTO can result in fines or billing errors, so we always advise patience for this final step.

If this sounds like a lot of paperwork, it is. But the good news? You don’t have to do any of it.

At Energy Solutions , our project coordinators live and breathe these codes. We know the inspectors by name, and we know exactly what the City of Portland or Clackamas County wants to see.

Your job is to dream about your savings. Our job is to handle the red tape.
