Outdoor lighting installation enhances security, safety, and curb appeal. We install wall-mounted sconces, LED flood lights, motion-sensor lights, post lights, and step/deck lighting. Each installation includes running weatherproof wiring (UF-B cable or THWN in conduit), mounting the fixture on a weatherproof electrical box, connecting to a switch or photocell/timer, and ensuring all connections are protected from moisture. GFCI protection is required on all outdoor circuits. Motion-sensor and dusk-to-dawn photocells reduce energy consumption by activating lights only when needed.

NorCal's long summer evenings and mild year-round climate make outdoor living spaces popular. Outdoor lighting extends usable evening hours and improves home security during shorter winter days.

Milpitas is located in Santa Clara County (South Bay). Diverse tech-industry suburb with newer townhomes and 1970s–80s tract housing. The local utility provider is PG&E.

California Building Code

NEC 210.8(A) requires GFCI protection on all outdoor outlets. NEC 410.10 requires wet-location-rated fixtures and boxes where exposed to weather. Underground wiring must be UF-B cable buried at least 12 inches deep (24 inches without conduit protection).

Project Timeline

Layout & Circuit Planning

20-30 min

Walk the property to determine fixture locations for optimal security and aesthetic coverage. Plan the circuit route from the panel or an existing outdoor circuit. Select control method (switch, photocell, motion sensor, or timer).

Wiring & Conduit Installation

2-4 hrs

Run UF-B cable underground or THWN wire through surface-mounted PVC conduit along exterior walls. Install weatherproof boxes at each fixture location. Connect the circuit to a GFCI-protected breaker.

Fixture Mounting & Connection

1-2 hrs

Mount each fixture on its weatherproof box, make wiring connections with waterproof wire nuts, and install in-use covers. Set up photocell, timer, or motion sensor controls.

Testing & Adjustment

20-30 min

Test all fixtures, adjust motion sensor range and sensitivity, verify photocell operation, and confirm timer programming. Ensure GFCI protection trips correctly.
