What Requires a Solar / Photovoltaic Permit in San Diego
San Diego's Development Services Department mandates permits for all solar photovoltaic installations that connect to the electrical grid or modify existing electrical systems. Residential and commercial solar projects must demonstrate compliance with California Energy Code, San Diego Building Code, and electrical safety standards. Projects involving structural modifications to roofs, electrical panel upgrades, or new mounting systems automatically trigger permit requirements. The DSD reviews solar plans to ensure proper load calculations, structural integrity, and electrical system compatibility.
What Doesn't Require a Permit
Portable solar devices under 250 watts typically do not require San Diego permitting. Temporary solar installations used for recreational vehicles or temporary structures may also bypass standard permit processes. However, any permanent solar system connected to residential or commercial electrical infrastructure must receive DSD approval, regardless of size or complexity.

Solar permit fees in San Diego vary based on project complexity and valuation. The Solar Instant Permit currently carries a flat fee of $275.80, applicable for straightforward residential installations. Commercial solar projects utilize a tiered fee structure, with projects valued under $50 incurring a $1,000 fee. Additional costs may include mapping fees ($11.34) and potential school development fees at $4.08 per square foot. Applicants should budget for plan review, electrical system evaluation, and potential structural assessment charges.
How Long Does Solar / Photovoltaic Permit Approval Take
San Diego's Development Services Department processes solar permits through multiple review channels. Standard residential solar permits typically require 10-15 business days for complete review and approval.
