Before requesting a battery addition or revised solar proposal for a City of San Diego home, gather the existing system's permit records and plans. They give the installer a starting point for checking what was approved, what is installed and what the new project would change.
A missing search result does not by itself prove that the system lacks permits. San Diego uses multiple records tools, and a permit summary is different from the underlying drawings. The following routes were checked October 12, 2026.
Start with the correct city search tool
The city's Development Services records page links OpenDSD, Permit Finder and Accela for researching permits and applications from 2003 onward. These are City of San Diego resources; a San Diego County mailing address does not establish that the city issued your permit.
There is a specific solar-related distinction: OpenDSD's search instructions direct residential rooftop solar PV permits submitted after January 16, 2018 to Accela. Check that route before concluding that an older system has no searchable record.
Save the project or permit number, address, description and displayed status. Ask city staff about unclear results rather than interpreting a project title as proof of completed approval.
Request plans separately when needed
The city says viewing or obtaining building plans requires an in-person appointment with its records team; plans are not available through the self-service option. It also cautions that not every type of property record may be available.
Use the records page's appointment route and identify the solar project you want to review. Ask what can be obtained and what requirements apply to copies. Meanwhile, request the original plan set and completion documents from the installer or current system owner, if available.
Give the designer a useful comparison packet
Collect these items for professional review:
- Existing solar and battery permit identifiers and available drawings.
- Equipment model information and any documented replacements.
- Utility interconnection or permission-to-operate correspondence you retain.
- The current solar ownership, lease or PPA agreement.
- Your proposed backup circuits and any new household loads.
For a hypothetical home with a replacement inverter, the original drawing might describe the earlier equipment. Ask the designer to reconcile the records with the installation before selecting compatible storage. Historical paperwork is a starting point, not a substitute for a site assessment or approval of the new work.
Keep utility and contract records alongside city records
San Diego Community Power explains that it supplies generation for enrolled customers while SDG&E continues electricity delivery and billing. Check your actual bill for enrollment. A city permit record does not establish your current generation plan or the terms of a private solar agreement.
A qualifying no-upfront solar-plus-battery PPA can provide access to equipment without an upfront purchase. The CPUC solar guide explains third-party ownership and ongoing electricity payments. Confirm whether the existing owner permits the proposed modification and who handles records, design, permits and any additional charges.
Review the energy rate, escalator, term, battery ownership, service and replacement coverage, transfer provisions and remaining utility costs. Offer and property eligibility still require verification.
Finally, document supported loads and realistic backup limits. PG&E's general battery guidance explains that available charge, demand and solar conditions affect duration; solar recharging requires suitable sunlight and compatible equipment.
