Plan Review

Permit applications can be submitted to Development Services Department in person at 276 Fourth Avenue Bldg B, Chula Vista, California 91910 and electronically through: Citizen Access

Permit applications utilizing standard plan may be approved “over-the-counter” at 276 Fourth Avenue Bldg B, Chula Vista, California 91910. Permits not approved “over-the-counter” should be reviewed in one to three days.



Homeowners and businesses interested in reducing their utility costs for heating water can now take advantage of significantly increased cash rebates for solar water heating systems from the California Solar Initiative – Thermal Program.

Starting this month, the California Public Utilities Commission raised incentives for solar water heating systems that displace natural gas use by 60 percent for residential installations and nearly 40 percent for commercial applications. The increased rebates present an opportunity to invigorate the solar water heating industry while offering both residential and commercial consumers ways to save money, cut energy use and reduce their carbon footprint.


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. On-site inspections can be scheduled by contacting the Development Services Department by telephone at (619) 409-5434 or electronically at Inspection requests received within business hours are typically scheduled for the next business day. If next business day is not available, inspection should happen within a five-day window.

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 checklist provides an overview of common points of inspection, and the applicant should be prepared to show compliance with these points.
