What’s Included in Our California Solar Permit Package

Every California permit package from Solar Permit Solutions includes the complete documentation set required by local AHJs and California state code.

Permit-Ready Solar Plan Sets

We produce complete permit plan sets formatted to California AHJ standards. Each plan set includes all sheets required for a full permit application submittal, reducing back-and-forth with the building department.

Electrical Single-Line Diagrams

Our single-line diagrams are drawn to NEC 2020 and NEC 2023 standards as adopted by California, covering AC and DC wiring, overcurrent protection, rapid shutdown compliance, and interconnection points.

Site Plans & Equipment Layouts

Detailed site plans show panel placement, setback compliance, roof access pathways, and equipment locations. Layouts are drawn to scale and include fire setback markings per California Fire Code requirements.

Structural Calculations

Licensed engineers provide structural calculations for roof-mounted systems, including dead load, wind uplift, and snow load analysis where applicable. Ground-mount projects include foundation and racking calculations.

PE-Stamped Engineering

All structural and electrical engineering documents are stamped by a professional engineer licensed in California. PE stamps are accepted by all 58 California counties and most local AHJs.

Utility Interconnection Documentation

We prepare interconnection packages for Pacific Gas and Electric, Southern California Edison, San Diego Gas & Electric, and other California utilities, including single-line diagrams and technical specifications aligned with each utility’s interconnection requirements.

California Solar Permit Requirements

California solar installations require both a building permit and an electrical permit in most jurisdictions. Local AHJs across the state enforce requirements based on adopted building codes, Title 24 energy standards, and the California Electrical Code (CEC), which adopts the NEC with California amendments.

Key compliance areas for California solar permits include the following:

Building permit requirements: Structural review of rooftop attachment, load path, and racking system
Electrical permit requirements: CEC/NEC compliance, disconnect labeling, overcurrent protection
California Building Code (CBC): Title 24 Part 2 applies to structural elements
NEC compliance: California adopts NEC 2020; some jurisdictions have adopted NEC 2023
Fire setbacks: Cal Fire and local fire departments enforce specific ridge, hip, and valley clearances
Rapid shutdown requirements: NEC 690.12 rapid shutdown is required for all rooftop systems in California

Requirements vary by AHJ. Los Angeles, San Francisco, Sacramento, and other municipalities may have additional local amendments or supplemental requirements.

Residential Solar Permit Plans in California

California added more residential solar capacity than any other state in the last decade, and with SB 100 and the state’s renewable energy mandates, installation activity remains high. Our residential permit plans cover every common project type:

Roof-mounted PV systems: New installations and system expansions for single-family and multi-family properties
Battery storage additions: Permit documentation for AC-coupled and DC-coupled battery systems, including load center modifications
Main panel upgrades: MPU documentation as required when existing service cannot support system interconnection
New construction solar: Permit plan sets for new builds required to include solar under California’s Title 24 mandate

We design residential plan sets to meet the specific submittal requirements of the local AHJ, reducing revision cycles and accelerating permit approval.

Agricultural projects: Farm buildings, winery facilities, and irrigation pump systems across the Central Valley and beyond
Schools and public facilities: K-12 and community college projects with Division of the State Architect (DSA) coordination as needed
Warehouses and distribution centers: Large-format rooftop systems with ballasted or attached racking
Carport and canopy structures: Freestanding shade structures with integrated PV requiring civil, structural, and electrical engineering

Commercial plan sets include complete structural calculations, equipment specifications, single-line diagrams, and utility interconnection documentation. Our PE-stamped drawings are accepted across California.
