Plan Review

Permit applications can be submitted electronically online through our Los Alamitos Permit Center. Alternatively, applications utilizing the standard plan may be approved “over the counter” at the Building Department if time permits. Permits not approved “over the counter” should be reviewed in one weeks time.


Residential solar plan review and permit fees are not to exceed $450.


Once all permits to construct the solar installation have been issued and the system has been installed, it must be inspected before final approval is granted for the solar system.

On-site inspections can be scheduled by contacting the Building Department through our Los Alamitos Permit Center. Inspection requests received prior to 5:00 p.m. are typically scheduled for the next business day.

Permit holders must be prepared to show conformance with all technical requirements in the field at the time of inspection. The inspector will verify that the installation is in conformance with applicable code requirements and with the approved plans. The Inspection Guide provides an overview of common points of inspection that the applicant should be prepared to show compliance.
