Outdoor Lighting on the Washington Coast — What Survives the Rain, and What Needs a Permit

It gets dark at five o'clock soon. That is usually when people notice the driveway they can't see, the shop door they're fumbling at, and the deck steps that were fine all summer.

Outdoor lighting on the Washington coast isn't the same job it is inland. We get nine months of rain, regular wind, and salt air if you're anywhere near the water. What you install has to handle that, or you'll be replacing it in two years.

The other reason to think about it now: anything that involves trenching wants dry ground. Once the rain sets in, a cable run to the shop turns into a mud job.

What to Sort Out Before You Buy Anything

Every outdoor fixture needs to be rated for wet locations, not damp. The difference is real: damp-rated handles indirect moisture like a covered porch, while wet-rated handles direct rain, standing water, and coastal spray. On the harbor, you want wet-rated.

Wire runs need planning rather than improvisation. Getting power to a detached shop, a fence line, or a dock means burying cable or running conduit. In Washington, outdoor circuits need a dedicated breaker with GFCI protection, and underground runs require UF-rated (underground feeder) cable or conduit. Regular NM — Romex — is not rated for ground burial, and we still find it out there.

Voltage decides whether this is a weekend job or ours. Most landscape lighting (path lights, accent lights) runs at 12V through a transformer, which is safe to do yourself. Anything structural is 120V and has to be done to code: a floodlight on the shop, a motion sensor on the garage, permanent posts for overhead string lights.

What Works Here

LED floodlights on the shop or garage. A pair on a motion sensor is the most practical upgrade available. Good ones last 50,000+ hours, draw very little, and do double duty as security lighting. Mount them high enough that you're not blinding your neighbours.

Hardwired path lighting along driveways. There are a lot of long driveways in rural Grays Harbor. Solar path lights are tempting and they do not work here — we don't get enough consistent sun from October through March, which is exactly the stretch you want them for. Low-voltage path lights on a transformer with a photocell come on at dusk and off at dawn, year-round.

Deck and patio post lights. Low-voltage LED post caps or recessed deck lights are durable, look good, and run off a transformer you can put on a timer. No permit needed for low-voltage landscape lighting in most jurisdictions.

Motion-activated security lighting with smart controls. Worth it if you have a shop, an outbuilding, or boat storage away from the house — you can control zones from your phone rather than walking out to a switch.

What to Skip

Cheap solar lights from the hardware store last one summer. In western Washington they barely charge enough to stay lit past ten in July; by November they're decoration.

Daisy-chained extension cords as permanent outdoor wiring — we see this more than we'd like. Cords are temporary by design. They're not rated for permanent outdoor use, they degrade in UV, and buried under mulch or run through a wall they're a fire hazard. If you need power somewhere, run proper wiring to it.

String lights hung on nails: the lights are fine, the nails aren't. Every nail through siding or fascia is a water entry point, and on this coast water always finds it. Use hooks or clips rated for outdoor mounting.

The Permit Question

In Grays Harbor County, electrical permits are required for new 120V outdoor circuits — running power to a shop, adding an outdoor panel, or putting permanent fixtures on new circuits. Low-voltage 12V landscape lighting doesn't require one.

Adding an outdoor GFCI outlet to an existing circuit depends on scope; check with the county. A permitted job means it was inspected, and that record matters for insurance and for resale.

Getting It Done Before the Weather Turns

If it involves trenching, the ground is still workable now and won't be for long. That is the only genuinely time-sensitive part — fixtures can go up any month of the year, but cable in the ground is a September and October job here.

A walkthrough of what you want lit and where power has to come from takes about half an hour and gives you a real number instead of a guess.
