PG&E Applicant Design & Utility Coordination

One of the most complex aspects of ADU development involves coordinating new electrical service with PG&E. Unlike simple remodels, ADUs typically require separate utility meters, dedicated service connections, and careful load calculations to ensure adequate power delivery.

GridSync’s PG&E applicant design services streamline this process. We prepare engineered electrical plans that meet utility specifications, coordinate service connection requirements, manage the application and approval process, and ensure your ADU receives proper electrical infrastructure from day one.

Understanding the Utility Coordination Process

The utility coordination process varies significantly based on your property’s existing service, the ADU’s location relative to the main dwelling, and available transformer capacity in your neighborhood. Our experience with San Francisco’s diverse housing stock—from Victorian homes in the Haight to modern construction in Mission Bay—enables us to navigate these variables efficiently.

💡 Pro Tip: Early engagement with PG&E for service planning can prevent significant project delays. GridSync initiates utility coordination during the design phase to keep your ADU project on schedule.

Key coordination services include:

  • Engineered electrical plans meeting PG&E specifications
  • Service connection requirement analysis
  • Application and approval process management
  • Transformer capacity assessment
  • Service upgrade coordination when necessary

Electrical Panel Sizing & Service Calculations

Determining appropriate electrical service size for an ADU requires comprehensive load calculations that account for lighting, appliances, HVAC systems, EV charging capability, and future expansion needs. Many ADU projects necessitate upgrades to the main property’s electrical service to accommodate the additional load.

GridSync performs detailed engineering analysis including:

  • Load calculations for the ADU
  • Assessment of existing service capacity
  • Evaluation of panel upgrade requirements
  • Design of electrical distribution systems that support both current needs and future electrification
⚠️ Service Upgrade Alert: For properties with 100-amp service—common in older San Francisco neighborhoods like the Richmond, Sunset, and Noe Valley—adding an ADU often triggers the need for service upgrades to 200 amps or more.

We coordinate these upgrades as integrated projects, ensuring both the main residence and ADU receive adequate electrical capacity. This comprehensive approach prevents future electrical issues and ensures your property can support modern electrical demands.

Complete ADU Electrical Design Services

GridSync provides comprehensive electrical design for all ADU types throughout San Francisco.

Detached ADUs

Detached ADUs present unique electrical challenges including:

  • Running service from the main panel or meter to a separate structure
  • Proper grounding and bonding systems
  • Weatherproof wiring methods for exterior runs
  • Integration with landscape and pathway lighting

Our designs account for the distance from main service to ADU, underground conduit routing, proper protection against physical damage, and aesthetic considerations for visible electrical components. We coordinate with landscape architects and general contractors to ensure electrical infrastructure integrates seamlessly with the overall project.

Attached ADUs & Garage Conversions

Attached ADUs and garage conversions may share electrical infrastructure with the main dwelling but still require careful planning for:

  • Separate metering when required
  • Adequate circuit capacity for the new living space
  • Proper separation of electrical systems
  • Compliance with fire-rated separation requirements

GridSync designs electrical systems that meet code requirements while maintaining practical functionality. For garage conversions, this often includes relocating existing electrical equipment, adding circuits for kitchen and laundry appliances, and upgrading lighting to residential standards.

JADUs (Junior Accessory Dwelling Units)

Junior ADUs, typically created within existing home footprints, require electrical modifications including:

  • Kitchen circuits for cooking appliances
  • Bathroom GFCI protection
  • Adequate lighting and receptacle circuits
  • Potential panel upgrades to support additional load

While JADUs are smaller than traditional ADUs, they still demand proper electrical design to ensure safety and code compliance.

Essential Electrical Components for San Francisco ADUs

Kitchen & Laundry Circuits

ADU kitchens require dedicated circuits for refrigerators, dishwashers, garbage disposals, microwave ovens, and multiple small appliance circuits for countertop use. If the ADU includes laundry facilities, separate circuits for washers and dryers are necessary, with proper sizing for electric dryers when applicable.

GridSync designs kitchen and laundry electrical systems that meet NEC requirements while providing the capacity and convenience modern living demands.

HVAC & Climate Control

Whether your ADU uses heat pumps, mini-split systems, or traditional HVAC equipment, proper electrical infrastructure is essential. This includes appropriately sized circuits for heating and cooling equipment, dedicated disconnect switches, proper overcurrent protection, and thermostat wiring.

As San Francisco increasingly emphasizes all-electric construction, many ADUs incorporate heat pump systems for both heating and cooling. Our designs accommodate these efficient systems with properly sized electrical service.

EV Charging Preparation

Forward-thinking ADU designs include provisions for electric vehicle charging, either as installed chargers or pre-wired circuits ready for future installation. This preparation adds significant value for tenants and future owners while avoiding costly retrofits later.

GridSync incorporates EV charging infrastructure into ADU electrical designs, including:

  • Load management systems when multiple charging points are planned
  • Dedicated circuits sized for Level 2 charging
  • Conduit and panel space for future expansion
  • Coordination with overall property electrical capacity

Smart Home & Technology Infrastructure

Modern ADUs benefit from integrated technology infrastructure including WiFi-ready electrical boxes, structured wiring for data and communications, smart thermostat compatibility, doorbell and security camera circuits, and provisions for whole-home automation systems.

We design electrical systems that support these features while maintaining flexibility for evolving technology needs.

Navigating San Francisco ADU Regulations

San Francisco’s ADU requirements include specific electrical provisions that must be addressed during design and permitting.

Code Compliance

All ADU electrical work must comply with:

  • California Electrical Code
  • San Francisco building codes and amendments
  • National Electrical Code standards
  • Title 24 energy efficiency requirements

GridSync’s engineers stay current with code updates and local amendments, ensuring your ADU electrical design meets all applicable standards.

Permitting & Inspections

Electrical permits are required for all ADU construction in San Francisco. GridSync manages the permitting process including:

  • Preparation of electrical plans for permit submittal
  • Coordination with San Francisco Department of Building Inspection
  • Scheduling of required inspections
  • Resolution of any plan check comments or field inspection issues

Our experience with San Francisco’s permitting process helps avoid delays and ensures smooth project progression from application through final approval.

PG&E Coordination Timeline

Utility coordination often represents a critical path item in ADU schedules. Early engagement with PG&E for service planning can prevent significant delays. GridSync initiates utility coordination during the design phase, submitting applications early and maintaining communication throughout the approval process.

💡 Timeline Tip: PG&E service coordination can take 8-12 weeks or more depending on service requirements. Start early to avoid construction delays.
