Licensed construction electrical wiring across Orange County. ADUs, room additions, garage conversions, guest houses, and new construction — rough-in through final inspection, all permits handled by ASL Electric.
ADUs are the fastest-growing construction project in Orange County right now. ASL Electric handles the complete electrical scope — from initial load calculation and panel assessment through rough-in, trim-out, and final city inspection. We work with your contractor or directly for owner-builders.
Complete electrical wiring for accessory dwelling units — detached ADUs, attached ADUs, and garage conversions. Includes subpanel installation, all rough-in wiring, HVAC circuits, kitchen appliance circuits, and final trim-out.
Most In-DemandConvert your garage to a living space, home office, or ADU. We add the wiring for lighting, outlets, HVAC, and mini-split circuits — everything needed to make a garage a functional, code-compliant living area.
Popular in OCNew bedroom, family room, bathroom, or home office addition electrical. Rough-in wiring during framing, all outlets and lighting locations, HVAC circuits, and panel capacity assessment to ensure your existing panel can handle the load.
Full ScopeDetached guest houses, casitas, and granny flats require their own subpanel, metering considerations, and complete interior wiring. ASL Electric handles the full electrical scope for standalone structures on your property.
Standalone StructuresElectrical rough-in during the framing stage of your construction project. We install all boxes, conduit runs, and wiring before the walls are closed — coordinating with your GC's schedule and city inspection requirements.
Construction PhaseFinal electrical installation after drywall — devices, fixtures, panel connections, and all final connections. We schedule the final inspection and walk it through to sign-off. Complete, documented, permitted finish.
Final PhaseSubpanel installation for ADUs, garages, workshops, and home additions that need their own distribution point. Properly sized for your project's load, with breakers for every circuit and all required safety devices.
Power DistributionUnderground electrical service runs from the main panel to a detached ADU, garage, or workshop. Proper burial depth, conduit, wire sizing, and disconnecting means at the structure — all per California code.
Detached StructuresTemporary power panel installation for construction projects — provides safe, code-compliant power to the job site during construction. Includes GFCI protection on all circuits as required for construction sites.
Construction SiteADU electrical is more complex than a standard home repair — it requires load calculations, subpanel design, underground runs, and multiple city inspections. We've completed ADU electrical scopes across all 16 OC cities.
"ASL handled our complete ADU electrical from permit application to final inspection. Coordinated perfectly with our GC. Passed inspection first try."

Before any ADU electrical scope begins, we assess your main panel's available capacity. Many OC homes need a panel upgrade before adding ADU loads. We identify this at estimate — not after rough-in.
ADU electrical permits in OC cities require plan check in many cases. We prepare the electrical drawings, submit them, respond to city comments, and schedule all inspections. You don't deal with the city.
We work directly with your general contractor — scheduling rough-in before insulation and drywall, coordinating with other subs, and meeting inspection deadlines that keep your project on schedule.
All California ADU and new construction electrical must comply with Title 24 energy code — specific requirements for lighting, outlets, and wiring methods. We build Title 24 compliance into every ADU scope from day one.

Real questions OC homeowners ask when planning ADU and construction electrical.
Many OC homes have 100-amp or 150-amp panels that are already near capacity. An ADU adds a kitchen, bathroom, HVAC, and lighting load that may require a 200-amp panel upgrade or a larger service entrance. We assess this as part of our estimate — before you're committed to a panel upgrade mid-project.
Not necessarily. ADUs can share the main home's meter (sub-metered internally) or have a separate utility meter depending on local city requirements and owner preference. SCE can provide a separate meter for a detached ADU. We advise on the best approach for your specific situation and city.
Rough-in for a typical 400–600 sq ft ADU takes 1–2 days. Trim-out after drywall takes 1 day. Underground service run from the main panel takes a half day. Total electrical labor time is typically 3–4 days spread across the project schedule.
Yes — we work as the electrical sub on GC-managed ADU and room addition projects regularly. We coordinate scheduling directly with your GC, meet inspection deadlines, and provide all required documentation. We're familiar with most OC cities' ADU permit processes.
A full ADU kitchen requires: a dedicated 20-amp small appliance circuit (required by code), a dedicated refrigerator circuit, a dedicated dishwasher circuit, a dedicated microwave circuit, and a range or cooktop circuit (240V for electric). We design the kitchen circuit layout based on your appliance plan.
Most mini-split systems require a dedicated 240V circuit — typically 20–30 amps depending on the unit size. We install the circuit to the location your HVAC sub specifies during rough-in. We coordinate directly with your HVAC contractor on circuit requirements.
Yes — garage conversions are one of our most common ADU projects in OC. The electrical scope includes upgrading the existing garage panel or running a new subpanel, adding all interior circuits, installing a mini-split circuit, kitchen circuits, and converting the garage door opener circuit. We've done this in all 16 target cities.
Yes. We prepare the electrical drawings required for permit application, submit to the city's building department, respond to any plan check comments, and schedule all inspections. ADU electrical permits in most OC cities require plan check — we handle that process entirely so it doesn't delay your project.
