Tujunga, Los Angeles, CA · February – March 2024 · LADWP / LADBS
A house and an ADU: two permits, two meters, two finals
Fifteen modules on the house and three on the ADU, installed the same day. Each building had its own permit and its own meter, so each went through its own final.
This Tujunga lot has solar on both the main house and its ADU: fifteen LA Solar 450 W modules on the house and three on the ADU, each with an Enphase IQ8M microinverter, 6.75 and 1.35 kW DC. Each building had its own LADBS permit, its own meter and its own final. Cali Energy installed both systems on 16 February 2024; both finals were passed on 5 March 2024, and LADBS approved the service release for both.

The story
There are two homes on this lot, the main house and an ADU, and each has its own address. That decides the paperwork: two LADBS permits, issued the same day in February 2024, one per building, and at the service two meters side by side, one per home. How solar works for a second home on a lot is set out in solar for an ADU in Los Angeles.
The installation was booked for Thursday 15 February and moved to Friday the 16th so the materials could arrive first. Both systems went in that day: fifteen LA Solar 450 W modules on the house and three on the ADU, every module with an Enphase IQ8M microinverter under it.
Each system carries its own placard at the service with its own figures: 20.25 amps maximum for the house and 4.05 for the ADU, fifteen and three microinverters at 1.35 amps each.
Both finals were requested for 28 February. LADBS issued a correction on each, and the crew was back on site the next morning. The new finals were set for Tuesday 5 March. For them, the inspector would check the breakers directly, including one in the subpanel inside the ADU, so access to the ADU was arranged with the homeowner, and the system paperwork, kept inside the gateway enclosure, was to be set out where the inspector could see it.
On 5 March both finals were passed, and LADBS approved the electrical service release for both permits the same day.
