The California City of Vacaville Launches Instant Solar Permitting, powered by Symbium

Tuesday August 15, 2023
Location: Vacaville, CA

VACAVILLE, CA - August 15, 2023 - Symbium and the City of Vacaville are proud to announce the launch of instant permits for residential solar and battery storage systems. Powered by Symbium – the Complaw® company whose technology translates complex laws and regulations into simple workflows – this groundbreaking platform verifies code compliance in real time and automates the issuance of solar and energy storage permits, lowering the costs for permit applicants and homeowners and increasing the speed of installing residential solar energy systems in Vacaville.

About California’s SB 379 Solar Permitting Mandate:

Symbium’s development of its solar permitting platform was catalyzed by Senate Bill (SB) 379. SB 379 is a recent California law that requires most California cities and counties to implement a platform that checks for code compliance and automates the issuance of permits for residential solar energy and storage systems. Such mandates to streamline the permitting of decarbonization projects are likely to proliferate as California and other States strive to meet the United States’s goal of 100% clean electricity by 2035.  

Uniquely Symbium:

Real-Time Code Compliance. Symbium automatically verifies compliance with State and local regulations, ensuring that every residential solar and battery storage system adheres to the required standards. Symbium’s solution is SB379-compliant. 

Instantaneous Regulatory Analysis. Symbium provides immediate, substantive feedback on why a scope of work meets or fails to meet regulatory requirements, allowing solar installers to quickly and easily revise their proposals to comply with the code.

Streamlined Permitting Process. Symbium provides a beautifully designed, user-friendly interface for solar installers to submit their permit applications. Installers can apply for permits and pay permit fees directly through Symbium, which integrates seamlessly with Vacaville’s permit tracking system. Symbium also automatically checks for a valid contractor’s and business license, instantly ensuring that only qualified professionals are submitting applications. 

California jurisdictions are invited to get in touch with Symbium to learn more about how Symbium can help streamline solar and other decarbonization permit processes in their communities. Symbium is currently enrolling California cities and counties in two free, pilot programs for solar permits and express, no-plan permits

Benefits of instant solar permits:

The automatic analysis of code compliance requirements and instant permit issuance not only ensures that every application meets the necessary safety and regulatory standards, decreases costs for homeowners and permit applicants, and increases the speed of solar installations. It will also help Vacaville residents decrease their energy emissions, which, in turn, will assist the City in achieving its Energy and Conservation Action Strategy goal of reducing greenhouse gas emissions to approximately 50% below 1990 equivalent emissions by 2035. 

City of Vacaville’s Director of Community Development, Erin Morris, expressed enthusiasm for the launch, stating, "We are thrilled to introduce this state-of-the-art online platform for our customers, which marks a significant step towards promoting renewable energy adoption and enhancing the ease of doing business in Vacaville. Our partnership with Symbium shows a commitment towards the City’s vision of providing excellence and innovation in customer service and advances several City Council’s strategic goals and initiatives such as strengthening the local economy and maintaining effective and efficient services. Symbium made the adoption of their well-designed platform easy and without requiring much staff time, even as the team integrated with our permit tracking system and customized the platform to respond to our local processes and code requirements.”

Vacaville will comply with California’s SB379 solar permitting mandate with the launch of this online platform, and Vacaville positions itself as a leader in fostering renewable energy adoption while prioritizing efficiency, safety, and sustainability. This initiative sets the stage for continued growth in the residential solar and battery storage sector, benefitting both the community and the environment.
