San Diego's Solar Energy: The Rules That Matter

Every city handles solar energy a little differently. In San Diego, California, there are 4 distinct rules that residents and property owners should be aware of. Some are stricter than what neighboring cities enforce, and others are more relaxed. Here is what you need to know.

Expedited Solar Permitting

Under California AB-2188 and SB-379, San Diego runs the Solar Express program issuing residential rooftop PV permits over the counter or online within one business day, with capped fees and a standardized streamlined checklist.

Key details: Statute: AB-2188 + SB-379. Turnaround: Often same business day. Size cap: Up to 15 kW residential. Fee cap: $450 statutorily. Portal: DSD Solar Express.

Installing solar without the Solar Express permit triggers stop-work orders and double fees on after-the-fact permits. Unpermitted PV cannot be interconnected by SDG&E, blocking net energy metering and creating insurance and resale problems for the homeowner.

The rules around expedited solar permitting in San Diego lean permissive, but that does not mean anything goes.

Community Solar

California SB-43 (2022) directs the CPUC to redesign community solar so renters and low-income San Diegans can subscribe to off-site solar through SDG&E programs like DAC-GT and the new Community Renewable Energy Program rolling out 2025-2026.

Key details: Statute: CA SB-43 (2022). Existing tariff: SDG&E DAC-GT. Discount: 20% for qualified low-income. Local CCA: San Diego Community Power. Rollout: CPUC 2025-2026.

There are no consumer violations for joining community solar, but unlicensed third-party subscription marketing without CPUC ESP registration can trigger CPUC enforcement and California Department of Justice action under the Unfair Competition Law.

If you are coming from a city with tighter rules, you will find San Diego gives residents more flexibility on community solar.

Panel Permits

A permit is required to install rooftop solar photovoltaic (PV) systems in San Diego. Rooftop-mounted systems on single-family homes and duplexes go through a streamlined permitting process. Ground-mounted systems, new support structures (carports, shade structures), or installations requiring structural modifications need a standard building permit. Solar energy systems are exempt from mechanical equipment screening provisions per SDMC §142.0905 and may be placed in side and rear yards.

Key details: Permit: Required; streamlined process for rooftop residential. Screening Exempt: SDMC §142.0905 exempts solar from screening. Yard Placement: Allowed in side and rear yards. Ground Mount: Standard building permit required. Battery Storage: Separate permit may be required.

Installation without permit: retroactive permit required plus fines $200 to $1,000. Electrical code violations: correction order. Failure to obtain utility interconnection: system must be disconnected.

HOA Restrictions

California's Solar Rights Act (Civil Code §714) prohibits HOAs and local governments from unreasonably restricting solar energy system installations. HOAs may impose reasonable restrictions that do not increase system cost by more than $1,000 or decrease efficiency by more than 10%. San Diego's municipal code supports solar access through SDMC §142.0905 exemptions. AB 2188 (2014) requires streamlined local permitting for small residential rooftop systems.

Key details: Solar Rights Act: CA Civil Code §714 protects solar installations. HOA Limits: Cannot increase cost >$1,000 or reduce efficiency >10%. AB 2188: Streamlined permitting required for small rooftop systems. Void Provisions: CC&R provisions restricting solar are void per state law. Local Support: SDMC §142.0905 exempts solar from screening.

HOA fines for non-compliance with aesthetic guidelines: varies by CC&Rs. Installing without HOA approval where required: typically $50 to $200 fines until resolved. HOA illegally blocking solar: homeowner may recover legal costs.

The rules around hoa restrictions in San Diego lean permissive, but that does not mean anything goes.

The Bottom Line

Compared to many U.S. cities, San Diego gives residents more room on solar energy. 3 of the 4 rules here are rated permissive. But permissive does not mean unregulated. There are still requirements, and the city does enforce them when violations are reported.
