Title 24 building standards require solar on new homes
Self-Generation Incentive Program (SGIP) for storage
Streamlined permitting in many jurisdictions
Overview
California's solar market is the largest in the United States, driven by aggressive state policies, abundant sunshine, and strong consumer demand. The state has set a target of 100% clean electricity by 2045, creating significant opportunities for solar and storage development across residential, commercial, and utility-scale sectors.
Permitting Guide
Siting Decision
For thermal power plants ≥50 MW, the California Energy Commission (CEC) runs the licensing process (AFC) and prepares CEQA EIR within its process; some projects can be exempted to local permitting via SPPE. The CEC also offers an Opt-In Certification Program (AB 205 pathway) where the CEC becomes the lead agency and runs a consolidated review for eligible clean energy projects.
Core Permits
CEQA (lead agency varies), SWPPP + Construction General Permit (State Water Board), wetlands/401/404, species (CDFW/FWS), cultural/tribal consultation; local conditional use permits still matter for non-CEC projects.
Common Challenges & Landmines
CEQA litigation risk; wildfire + WUI constraints; county solar/BESS ordinances differ wildly; ag conversion friction (CV, Central Coast). Local moratoria + ordinance churn (solar setbacks, BESS bans, decommissioning bonds) are usually the #1 surprise cost. Stormwater + erosion compliance (CGP/SWPPP) enforcement risk + stop-work exposure. Wetlands/401/404 + floodplain can be route/site killers—plan alternatives early. BESS fire code adoption + AHJ posture: IFC/NFPA 855/UL 9540A documentation expectations vary by locality.
Tax Considerations
Property tax is local assessor-driven; large projects often end up negotiating abatements/PILOT-like structures. Tax reality: property tax is commonly local and negotiable; incentives are often deal-specific.
Data Center Considerations
Focus on diesel generator air permitting, noise, water supply/wastewater capacity, and utility "make-ready" upgrades (often the long pole). Title 24 energy code has specific requirements for computer rooms and data centers, including cooling/economizer and controls requirements. Local zoning fights often focus on diesel backup generation, noise, and water/cooling strategy—treat these as first-class permitting items, not afterthoughts.
Permitting Pathways
Local governments control most zoning and building approvals for generation, storage, and data centers. However, the California Energy Commission (CEC) offers an Opt-In Certification Program (AB 205 pathway) where the CEC becomes the lead agency and runs a consolidated review for eligible clean energy projects. This can bypass local politics, moratoria, or schedule risk. Under CEC Opt-In, environmental review is targeted for completion within 270 days after an application is deemed complete.
Environmental Review (CEQA)
Utility-scale projects typically require a CEQA document (EIR, MND, or ND) with a public process. Under the CEC Opt-In pathway, the CEC serves as lead agency on a defined schedule. Screen early for wetlands/streams, species, cultural resources, wildfire interface zones, and BESS fire code expectations—these are often the real schedule killers.
Storage Opportunities
California leads the nation in energy storage deployment, driven by the Self-Generation Incentive Program (SGIP) and growing demand for grid resilience. Battery storage paired with solar is increasingly common for both residential and commercial projects, with favorable economics driven by time-of-use rates and demand charge management.
Frequently Asked Questions
What is the typical permitting timeline in California?
Permitting timelines vary by jurisdiction, ranging from same-day approval in streamlined jurisdictions to 4-6 weeks in areas with more complex review processes. Using the CEC Opt-In pathway targets environmental review completion within 270 days. Utility interconnection typically adds additional time depending on grid constraints.
Should I use local permitting or CEC Opt-In?
Consider CEC Opt-In when local politics, moratoria, or schedule risk dominate. The CEC becomes the lead agency and runs a consolidated review for eligible clean energy projects. For straightforward projects in solar-friendly jurisdictions, local entitlements may be faster.
Are there moratoria on solar development?
While California generally supports solar development, some counties have implemented restrictions on utility-scale projects, particularly in agricultural areas. Spark tracks these moratoria in real-time to help you identify viable sites.
