Electrical Load Service Analysis (ELSA)
Load Calculations for Panel Upgrades, ADUs & EV Chargers
Existing circuits are tallied, NEC Article 220 demand factors applied, and the new load, EV charger, ADU, or subpanel is added; then the total is compared against your service rating to confirm capacity.
PG&E Coordination & Service Sizing
Calculated demand gets submitted to PG&E, the correct meter and service size requested, disconnect and reconnect scheduled, and their crew coordinated with our upgrade so power returns without gaps.
Electrical Code Corrections & Compliance
Outdated Wiring & Panel Corrections
Knob-and-tube, aluminum branch wiring, and recalled Zinsco or FPE panels get identified, then replaced with copper conductors and a modern breaker panel wired to current NEC standards.
Grounding, Bonding & GFCI/AFCI Compliance
Grounding electrode conductors and bonding jumpers are verified at the panel, water line, and gas line, then GFCI and AFCI breakers installed on the circuits code now requires.
Commercial & Multifamily Code Compliance
Tenant spaces and unit panels are inspected against Title 24 and NEC, deficiencies documented, corrections completed per circuit, and each unit signed off for occupancy and inspection.
Real Estate Inspection Fixes
Pre-Sale Electrical Repairs
Home-inspection reports are reviewed line by line, flagged items like open junction boxes, reversed polarity, and double-tapped breakers repaired, then documented so the listing clears escrow without delay.
Buyer & Lender-Required Corrections
Buyer requests and FHA or VA appraiser conditions are addressed directly: ungrounded outlets, missing GFCIs, and unsafe panels corrected, then a signed invoice provided to satisfy lender and closing requirements.
Permit Closeouts for Unpermitted Electrical Work
Electrical work done without a permit, by a previous owner, a handyman, or a since-expired application, can stall a sale or fail an inspection. Electric Heroes legalizes that work retroactively. The existing installation is examined against current code, sections of drywall or covers opened where a city inspector needs eyes on conductors and connections, and any deficiency corrected before sign-off. A retroactive permit is then filed with the Walnut Creek or county building department, the inspection scheduled, and the record closed. Expired or abandoned permits from earlier projects are reopened and finalized so the property carries a clean, documented electrical history.
ELSA & Code Compliance Cost in Walnut Creek
Pricing depends on the scope of the analysis and the corrections it uncovers. Most visits begin with a $295 diagnostic fee, waived when the work proceeds. A standalone Electrical Load Service Analysis for a panel upgrade, ADU, or EV charger is priced flat once the scope is clear. Code corrections are quoted per item; grounding and bonding fixes, GFCI or AFCI additions, and outlet repairs each carry their own line.
Larger jobs such as a 100A-to-200A service upgrade generally run $3,500 to $6,500. Every quote is written before work starts, with permit and PG&E coordination fees itemized so nothing appears after the fact.
Service Areas for ELSA & Code Compliance
Our regular coverage includes Concord, Pleasant Hill, Clayton, Martinez, Lafayette, Alamo, Danville, Orinda, and Moraga, along with San Francisco, Oakland, and Berkeley. Each city and county runs its own permit process and inspection schedule, and those local requirements are handled directly for every job.
Load analyses, corrections, and permit closeouts are all managed in-house under CSLB #1054647, with no subcontracted crews. Response to central East Bay cities typically runs 45 to 90 minutes during business hours, with 24/7 availability for urgent code and safety issues.
