What Requires a Solar / Photovoltaic Permit in San Francisco

Solar installations in San Francisco require a permit when modifying electrical systems, mounting structures, or connecting to the city's power grid. The DBI mandates permits for all photovoltaic systems over 1 kilowatt, including roof-mounted, ground-mounted, and building-integrated solar arrays. New construction and retrofit projects must demonstrate compliance with San Francisco's stringent building codes, which prioritize seismic resilience and energy efficiency. Property owners must submit detailed engineering plans showing structural load calculations, electrical diagrams, and roof attachment methods specific to San Francisco's unique architectural landscape.

What Doesn't Require a Permit

Certain solar installations in San Francisco do not require a full permit process. Portable solar systems under 500 watts that do not connect to building electrical systems typically bypass standard permitting. Temporary solar equipment used for construction sites or temporary structures might also avoid comprehensive review. However, property owners should always confirm exemption status with the DBI, as San Francisco's strict building regulations can introduce unexpected requirements.

Solar / Photovoltaic Permit Costs and Fees in San Francisco

San Francisco's solar permit fees are structured based on project valuation and complexity. The base solar permit fee is $261, effective 2024-07-01. Additional fees may include building permit charges calculated on a tiered system ranging from $182 base for projects under $2,000 to more complex fee structures for larger installations. Contractors and homeowners should budget for potential supplementary charges such as site circulation reviews ($12,202) or environmental impact assessments. The Department of Building Inspection calculates fees dynamically, considering project scope, electrical modifications, and structural changes.

How Long Does Solar / Photovoltaic Permit Approval Take

Solar permit processing times at San Francisco's DBI vary based on project complexity and current departmental workload. Standard residential solar permits typically require 2-4 weeks for initial review and approval. Complex installations involving significant electrical or structural modifications might extend processing to 6-8 weeks. Property owners can expedite review by submitting comprehensive, precise documentation and ensuring all required engineering specifications meet San Francisco's strict building standards.

Required Documents for San Francisco Solar / Photovoltaic Permit

San Francisco's DBI requires a comprehensive document package for solar permit applications. Essential submissions include detailed site plans, electrical diagrams, structural load calculations, manufacturer specifications for solar panels and mounting systems, and proof of contractor licensing. Digital submissions through the SFDBI Portal are preferred, with high-resolution PDF documents recommended. Property owners must demonstrate compliance with California Title 24 energy efficiency standards and San Francisco's unique seismic retrofit requirements.
