How Much Does an Electric Driveway Gate Cost in Seattle? 2026 Price Guide

Electric driveway gate cost by type

Published Washington price ranges in 2026 put a single swing gate at $2,500 to $8,000 installed, a dual (double) swing gate at $4,000 to $15,000 and up, a sliding gate at $3,500 to $9,000, and custom ornamental iron at $8,000 to $20,000 or more. National cost surveys line up with the middle of those ranges: HomeGuide reports $1,600 to $13,000 with a typical project around $7,000, and Fixr puts the national average near $4,000 with most jobs between $2,500 and $5,500. Seattle and Bellevue sit in the upper half because labor rates run well above the national average and because many Eastside lots need site work before a gate can go in. If you already have a manual gate in good condition, automating it with an operator and controls alone runs about $400 to $5,500 depending on the hardware.

What the gate panel itself costs

The panel is where material drives the price. Cedar and other wood gates run roughly $400 to $8,500 before installation and match the fencing on most Northwest homes, but they need sealing every few years to survive our wet winters. Aluminum ($1,500 to $8,600) is the low-maintenance choice because it never rusts and keeps a sliding operator light. Steel and wrought iron ($600 to $8,600) give the classic estate look and the most security, with powder coating essential in our climate. Vinyl ($350 to $5,600) is the budget option but struggles with wide spans. For context, a plain 12-foot manual wood double swing gate costs $2,000 to $5,000 installed in Washington before any automation is added.

Gate openers, power and controls

The operator (opener) is the second-largest line item. Light-duty residential openers run $200 to $1,000, medium-duty $350 to $2,000 and heavy-duty units for long or heavy gates $450 to $5,000. Battery-backed hardwired openers are the norm; solar kits ($500 to $2,000 for the opener, or $2,000 to $6,000 for a full solar power system) make sense when the gate is far from the house. Getting power to the gate is the surprise cost on many bids — electrical wiring runs $500 to $2,000 and trenching across a long driveway $2,000 to $5,000. Access controls add up quickly: a keypad is $400 to $800 installed, a video intercom $1,500 to $5,000, a camera $125 to $2,000, a vehicle exit loop $200 to $500, and extra remotes $75 to $300 each. Labor for the whole installation typically totals $800 to $4,800.

Permits and rules in Seattle, Bellevue and the Eastside

Three sets of rules apply to most residential gates. First, Washington L&I requires an electrical permit and inspection for the hardwired circuit feeding the operator; that permit is pulled by the licensed electrician doing the work. Second, zoning codes in Seattle and the Eastside cities limit fence and gate height in the front setback — commonly four feet in front yards and six feet along side and rear property lines — so a tall privacy gate at the street usually needs a setback or a variance. Third, Bellevue Fire and most Eastside fire districts require an approved emergency-access device such as a Knox key switch or Click2Enter on automated gates across a driveway serving a home. Every operator should also meet the UL 325 safety standard with two entrapment-protection devices in each direction of travel; unpermitted or non-compliant installations can void insurance coverage. Our Washington permit guide and Seattle vs. Eastside permit timelines explain how the review process works city by city.

Swing, sliding or vertical lift: which fits your driveway?

Swing gates are the simplest and least expensive, but they need level ground and clear room inside the driveway for the leaves to arc open. On the sloped lots common in Bellevue, Issaquah, Sammamish, Mercer Island and West Seattle, or where the house sits close to the street, a sliding or cantilever gate that travels parallel to the fence line is the better fit: it keeps the full driveway width clear, handles grade changes and is harder to force open. Cantilever gates cost more because they need a counterbalance section roughly half the opening width, but they avoid a ground track that collects leaves and ice. Vertical lift and bi-fold gates are rare on homes and reserved for very tight urban lots. A good installer measures the grade, setbacks and your vehicles' turning radius before recommending a style.

Timeline and maintenance

Custom gate fabrication typically takes four to six weeks; once the gate arrives, the on-site work — posts or footings, trenching, operator and control installation, and programming — is usually one to two days. Plan on lubricating hinges, rollers and chains every three to six months (more often on a gate that cycles many times a day), an annual safety check of the photo eyes and edge sensors, and an opener battery replacement ($20 to $85) every few years. Repairs average $500 to $1,000, and a well-built gate and operator should last 10 to 15 years. Electricity to run the opener costs only a few dollars a month.

Bundle the gate with the rest of the front yard

Because trenching, concrete and permits are shared costs, the most economical time to add a gate is while other exterior work is underway. Most of our gate projects are paired with new cedar or composite fencing (see our fence cost guide), a new concrete or paver driveway with a proper apron at the gate, landscape lighting, or an electrical panel upgrade for an EV charger run through the same trench. Doing it all once also means one permit set and one inspection schedule instead of three.
