Simi Valley, CA · October 2023 · Southern California Edison / City of Simi Valley

The array passed. The house had one thing missing.

A Simi Valley solar final that came back with a single correction, and it was not about the modules, the conduit or the panel. It was a smoke and carbon monoxide requirement that predates the project.

California requires working carbon monoxide alarms in dwellings with fuel-burning appliances or an attached garage, and when permitted work is done the inspector checks for them. On this Simi Valley project the array passed and the sign-off was held for a hard-wired alarm the house did not have. Cali Energy installed it, photographed it and sent the photographs to the inspector, who closed the permit remotely. A solar final is an inspection of the house as well as the array.

The story

The final inspection on this Simi Valley installation went the way finals usually go. The inspector looked at the array, the conduit, the labeling and the disconnects, and had nothing to say about any of it. Then he wrote one correction: the house needed a hard-wired carbon monoxide alarm.

That is not a solar requirement and it is not a new one. California requires carbon monoxide alarms in dwellings that have fuel-burning appliances, an attached garage or a fireplace, and the obligation attaches to the house rather than to any particular project. What a permit does is bring an inspector into the building, and an inspector who is standing there is going to notice.

So a solar final becomes, in practice, a partial check of the dwelling. Smoke alarms in the right rooms. Carbon monoxide alarms where the code asks for them. Sometimes water heater strapping. None of it was caused by the solar work and all of it can hold the sign-off.

Cali Energy installed the alarm at no charge, photographed it and sent the photographs to the inspector, who closed the permit remotely rather than scheduling a second visit. That last part is worth noticing: many corrections can be cleared with documentation rather than another appointment, and asking is free.

One other thing was settled on this project before the final, and it saved a different kind of delay. Some California cities require a signed carbon monoxide compliance form with the permit paperwork; others do not. Rather than assume, the question was put to the city directly, and the answer was that Simi Valley does not require the form. Five minutes on the phone against a week of guessing.

The system was left running three days after the final.

How it ran

One correction, cleared the same day without a second inspection visit. This timeline reflects this property and this inspector.

What we did

• Asked the city in advance whether a carbon monoxide compliance form was required rather than assuming (C-10).
• Presented the installation for final inspection with labeling and disconnects complete.
• Installed the hard-wired carbon monoxide alarm the correction called for, at no charge to the owner.
• Photographed the work and submitted it so the inspector could close the permit remotely.
• Switched the system on once the permit was closed.

Frequently asked questions

Why did a solar inspection raise a carbon monoxide alarm?

Because the requirement belongs to the dwelling, not to the project. California requires carbon monoxide alarms in homes with fuel-burning appliances, an attached garage or a fireplace, and a permit brings an inspector into the house who is obliged to notice. The array itself passed without comment on this project.

Does Cali Energy handle inspection corrections in Simi Valley?

Yes, including corrections that are not about the solar work. On this project Cali Energy installed the alarm the inspector asked for at no charge, photographed it and submitted the evidence so the permit could be closed without a second visit. Fifteen Simi Valley projects are written up on our projects page. Our license is CSLB #1032379.

Does a correction always mean another inspection visit?

No. Many inspectors will close a permit on photographic evidence when the correction is simple and verifiable, which saves days of scheduling. It is worth asking rather than assuming a second appointment. On this project the alarm was installed and photographed the same day and the permit was closed remotely.

What else gets checked at a solar final?

The array attachments and flashing, the conduit runs, the disconnects and placards, the labeling at the service equipment and the point of connection. Alongside that, inspectors commonly check dwelling life-safety items: smoke alarms, carbon monoxide alarms and sometimes water heater strapping. None of those are caused by solar and all of them can hold a sign-off.
