Recessed lighting (also called can lights or pot lights) is installed flush into the ceiling for a clean, modern look. In San Diego, professional recessed lighting installation typically costs $150-$300 per light, depending on ceiling type and whether new wiring is required. A full room installation (6-10 lights) usually runs $900-$2,500. LED recessed lights are the most energy-efficient option and can reduce lighting costs by up to 75% compared to incandescent bulbs. Optimal Electric installs recessed lighting throughout San Diego County.

GFCI (Ground Fault Circuit Interrupter) outlets are safety devices that cut power within milliseconds if they detect a ground fault, preventing electric shock. California building code requires GFCI outlets in all kitchens, bathrooms, garages, outdoor areas, crawl spaces, unfinished basements, and near swimming pools. GFCI outlet installation costs $80-$200 per outlet in San Diego. If your home was built before 1975, you likely need GFCI upgrades throughout. Optimal Electric performs GFCI inspections and upgrades for San Diego homeowners.

Signs your San Diego home may need rewiring include: flickering or dimming lights, frequently tripping breakers, burning smell from outlets or walls, discolored or warm outlet covers, two-prong ungrounded outlets throughout the home, aluminum wiring (common in homes built 1965-1973), or a home over 40 years old that has never been rewired. Full home rewiring in San Diego costs $8,000-$20,000 depending on home size. This is a major investment that dramatically improves safety and can lower homeowner’s insurance rates. Call Optimal Electric for a free inspection.

The City of San Diego requires electrical permits for most significant electrical work including: new circuits, panel upgrades, EV charger installation, new construction wiring, major renovations, and service changes. Simple No-Plan permits are available for minor work like meter resets. Plan permits are required for larger projects and involve submitting electrical drawings for review. Permits are issued by the City of San Diego Development Services Department. A licensed electrician will handle the permit application and inspection process. Working without required permits can result in fines and require costly rework.

A 100-amp panel is the minimum service for modern homes and can support basic appliances, lighting, and HVAC. However, it may be insufficient if you have an EV charger, hot tub, large AC system, or plan to add solar panels. A 200-amp panel is the current standard for new construction and provides ample capacity for modern electrical loads. Upgrading from 100A to 200A in San Diego typically costs $2,000-$4,500 including labor, materials, and permits. Some larger homes or those with multiple EV chargers may benefit from a 400-amp service. Optimal Electric handles all panel upgrades in San Diego.

Yes, Optimal Electric can handle the electrical work associated with solar panel installations in San Diego, including panel upgrades to accommodate solar inverters, sub-panel installations, battery storage system wiring (such as Tesla Powerwall), and EV charger integration with solar systems. San Diego has one of the highest solar adoption rates in the country due to its abundant sunshine and high electricity rates. A solar-ready panel upgrade typically costs $2,500-$5,000. Contact Optimal Electric at (619) 609-3037 to discuss your solar electrical needs.

Project timelines vary significantly by scope. Minor repairs (outlet replacement, GFCI install, ceiling fan) typically take 1-3 hours. Panel upgrades usually take a full day (6-8 hours) and require a utility disconnect from SDGE. Whole-home rewiring can take 3-7 days depending on home size. New construction wiring is scheduled in phases (rough-in and trim-out) around other trades. Optimal Electric provides detailed project timelines during the estimate process and works to minimize disruption to your home or business.
