Our Work



Benefits
Built for Tomorrow and Business Resilience
Commercial rewiring is a strategic investment in business continuity, safety, and future capacity. We design electrical systems that exceed minimum code requirements—incorporating adequate service capacity for business growth (typically 200A–600A depending on building size and tenant mix), dedicated circuits for HVAC equipment, commercial kitchen appliances, IT/server rooms, point-of-sale systems, and specialty equipment, provisions for submetering when multiple tenants share service, whole-building surge protection to safeguard expensive equipment, emergency and backup power provisions (generator or battery backup systems), and EV charging infrastructure for employee and customer vehicles. Our designs include Title 24-compliant lighting controls with occupancy sensing, daylighting, and demand response capabilities; conduit pathways for future technology upgrades and tenant improvements; optional smart panel technology with remote monitoring and energy management; and robust grounding, bonding, and surge protection. Every Altadena commercial property we rewire is designed to minimize downtime, reduce operating costs, meet stringent code requirements, and adapt to evolving tenant and technology needs.
Permits, Compliance, and Fire Recovery Coordination
Shaffer Construction manages all aspects of commercial permitting with Los Angeles County Building and Safety. We prepare comprehensive plan sets including service and feeder load calculations, one-line diagrams showing service equipment and distribution, detailed panel schedules for all distribution panels, branch circuiting plans, Title 24 Part 6 energy compliance documentation and lighting control diagrams, emergency and egress lighting plans coordinated with County Fire Department requirements, and grounding and bonding details. For Eaton Fire recovery projects, we coordinate with insurance carriers to provide detailed damage documentation and restoration scopes for claims processing, work with FEMA representatives when federal disaster assistance is available, and provide all documentation needed for expedited permit processing. We manage SCE service restoration and upgrades (including transformer upgrades for increased capacity), coordinate County Fire Department review for life safety systems, and schedule all required inspections (rough, underground, final) to keep projects on schedule and businesses operational. Our goal is compliant, efficient permitting and approval that minimizes delays and gets businesses serving the Altadena community as quickly as possible.
Plan-First Custom Design and Phasing
Every commercial property has unique electrical requirements, tenant needs, equipment loads, and operational constraints. We begin with comprehensive site assessment and load analysis—reviewing current and projected equipment requirements, measuring existing loads and power quality, identifying code deficiencies and fire damage extent, evaluating access points and distribution pathways, and assessing options for phasing work to minimize business disruption. Our design packages include detailed circuiting plans for tenant spaces and common areas, comprehensive panel schedules and one-line diagrams, Title 24 energy compliance calculations and lighting control diagrams, emergency and egress lighting layouts with battery backup, low-voltage and data pathway coordination, service and feeder load calculations with future growth provisions, and detailed phasing plans for occupied buildings showing which areas will be affected and when. For multi-tenant properties, we design proper tenant separation, individual metering, and coordination plans for tenant notifications and access. We can schedule installation work during nights or weekends when needed, provide temporary power to maintain business operations, and deliver complete as-built drawings and panel schedules for facilities management and future tenant improvements.
What We Offer
Frequently Asked Questions
How long does commercial rewiring take for an Eaton Fire-damaged Altadena property?+
Project duration varies significantly with building size, damage extent, and operational constraints. Small retail or office spaces (1,000–3,000 sq ft) typically require 2–4 weeks of on-site electrical work. Larger buildings or multi-tenant properties (5,000–20,000+ sq ft) may require 6–12 weeks depending on scope and phasing requirements. Permitting through LA County Building and Safety adds 2–5 weeks (expedited processing available for documented fire recovery). We provide detailed schedules during planning showing phasing, critical milestones, and estimated completion dates.
Can businesses remain operational during rewiring?+
Often yes, with proper planning and phasing. We commonly phase work area-by-area or by tenant space, install temporary power distribution to maintain essential services, and schedule the most disruptive work (service cutovers, main panel installations, distribution upgrades) during nights, weekends, or planned closure periods. For restaurants, retail, and offices with regular business hours, we coordinate detailed schedules with managers to minimize customer and operational impacts. You’ll receive a comprehensive phasing plan during design so you can plan staffing, communicate with customers, and maintain business operations to the greatest extent possible.
Will commercial property insurance cover rewiring after the Eaton Fire?+
Most commercial property insurance policies with building coverage include fire damage restoration for electrical systems and equipment. We thoroughly document pre-loss conditions (using available records, photographs, and professional assessments), photograph fire damage from multiple angles, provide detailed restoration scopes and estimates formatted for insurance submission and adjuster review, and can work directly with insurance adjusters and public adjusters when authorized by property owners. Our proposals clearly separate insurance-covered fire damage restoration from optional improvements (such as upgraded service capacity, smart panels, enhanced surge protection, or EV charging infrastructure) to support accurate claims processing and informed decision-making.
What does commercial rewiring cost in Altadena?+
Costs vary widely with building size, construction type, fire damage extent, service capacity requirements, tenant improvements, and accessibility factors. Small retail or office suites (1,000–3,000 sq ft), mid-size buildings (5,000–10,000 sq ft), and larger multi-tenant buildings all have different requirements. Pricing depends on scope, service capacity (up to 800A+ three-phase), number of tenants/meters, specialty systems, and finish requirements. After our comprehensive on-site assessment, we provide detailed, itemized proposals breaking down service equipment, distribution systems, branch circuits, lighting and controls, emergency systems, and options including EV charging, backup power, and solar/battery integration.
