QUICK ANSWER

Which deck builders work in Seattle, WA?

Cactus Decking is a licensed, bonded, and insured deck builder and deck contractor serving Seattle homeowners from our base at 12029 24th Ave SE in Everett, about 18 miles from Northgate. We build new decks, replace and repair old ones, and install railings, stairs, pergolas, covers, and lighting. Seattle's permit rule is stricter than most cities: SDCI requires a permit for decks more than 18 inches above the ground, for roof decks, and for any deck in an environmentally critical area. Most decks qualify for a subject-to-field-inspection permit, and we handle the application. Estimates are free and written, and our work carries a 10-year workmanship warranty.

Seattle neighborhoods we serve

Type your neighborhood or ZIP code to check coverage and see what decks there usually need.

Bitter Lake, Haller Lake & Broadview

9813398177

The closest Seattle neighborhoods to our Everett base. Lots near the Puget Sound bluffs get an ECA check before design.

Northgate, Lake City & Pinehurst

98125

About 18 miles from our shop, so site visits and follow-ups are easy to schedule.

Ballard & Crown Hill

9810798117

Many older homes on narrow lots, so we plan side setbacks, material delivery, and the ledger connection early.

Greenwood, Phinney Ridge, Fremont & Wallingford

98103

Hillside streets and older houses: we check slopes against the ECA map and inspect the house framing before attaching a deck.

Green Lake, Roosevelt & Ravenna

9810398115

Compact back yards where a raised deck adds usable space. Setbacks and the 36-inch lot coverage rule shape the footprint.

Maple Leaf, Wedgwood & View Ridge

98115

Established neighborhoods where many original wood decks are due for replacement or resurfacing.

Laurelhurst & University District

98105

View lots where glass and cable railings are popular. Glass guards have extra Seattle code requirements, which we design for.

What Seattle deck plans need

The 18-inch permit rule

Seattle exempts only decks 18 inches or less above grade. Higher decks need an SDCI permit, usually a subject-to-field-inspection (STFI) permit. Decks over 8 ft high, over 750 sq ft, or with beams 14 ft or longer need a full permit with plan review.

Setbacks and lot coverage

Decks over 18 inches must stay 10 to 15 ft from the front property line and 3 to 5 ft from side lines in neighborhood residential zones. Over 36 inches, the deck counts toward the lot's 50% coverage limit. On narrow Seattle lots this often decides the deck's size.

Steep slopes and critical areas

Many Seattle lots sit on steep or landslide-prone slopes. Decks in or near an environmentally critical area (ECA) need an SDCI site visit before any permit, so we check the city's ECA map for your address first.

Older homes and seismic ledgers

About 36% of Seattle's housing was built before 1960. SDCI requires a ledger connection that won't pull away in an earthquake and a 60 psf design load, so we open up and check the house framing before attaching a new deck.

Trees on the lot

Seattle regulates trees 6 inches in diameter and larger, in tiers by size, and removing one needs public notice. We place footings and plan the layout around protected trees and their roots instead of assuming they can go.

156 wet days a year

Sea-Tac averages 39 inches of rain over about 156 days a year. Capped composite or PVC boards, slip-resistant stair treads, airflow under the deck, and flashing at the house connection matter more here than looks alone.

TRY IT

Does your Seattle deck need a permit?

How high is the deck floor above the ground?

Is the lot on a steep slope or in a landslide- or flood-prone area?

Anything else true? Tick all that apply
Likely permit

Subject-to-field-inspection (STFI) permit

Most Seattle decks over 18 in. need only an STFI permit, which inspectors check on site. Decks over 18 in. must also meet zoning setbacks, and decks over 36 in. count toward lot coverage.

Based on SDCI's deck rules. SDCI makes the final call; we confirm for your address before pricing.

SERVICE AREA

Our Seattle service area

Cactus Decking is based in Everett, about 20 miles away, and builds, replaces, and repairs decks throughout Seattle.

Seattle decks frequently involve compact lots, close neighbors, hillside access, and older home connections. Planning may require special attention to privacy, drainage, ledger conditions, safe stairs, and moving materials through limited access. Wet shade and tree debris also affect surface selection, ventilation, and the maintenance plan.

A Seattle estimate begins with the actual property rather than a citywide assumption. We review the existing structure or proposed footprint, access, drainage, stairs, railings, material exposure, permit needs, and how the household plans to use the space. That review determines which service and material options are appropriate.

Common deck questions in Seattle

Is there a deck builder near me in Seattle?

Yes. Cactus Decking serves Seattle from 12029 24th Ave SE in Everett, about 18 miles from Northgate and 24 miles from downtown. North Seattle neighborhoods such as Lake City, Northgate, Ballard, Greenwood, and Wedgwood are closest. We give free on-site estimates and back our work with a 10-year workmanship warranty.

Do I need a permit to build a deck in Seattle?

You need an SDCI permit if the deck is more than 18 inches above the ground, is a roof deck, or is in an environmentally critical area. Most decks need only a subject-to-field-inspection permit. Decks more than 8 ft high, over 750 sq ft, with beams 14 ft or longer, or with solid flooring need a full addition or alteration permit. Cactus Decking prepares the drawings and handles the application.

How much does a new deck cost in Seattle?

Our typical projects range from about $20,000 for a 12 × 12 ft composite deck with aluminum railing to about $70,000 for a 500 sq ft custom PVC deck with lighting and built-in seating. In Seattle, height, slope, access on narrow lots, and permit type move the price most. Every estimate is free and written.

How close to my property line can I build a deck in Seattle?

Decks under 18 inches have no setback limits outside critical areas. Higher decks must stay 10 to 15 ft from the front property line, 3 to 5 ft from side lines, and 5 to 15 ft from the rear line in neighborhood residential zones, depending on the lot. We check your zone and lot before drawing the deck.

Do you build decks on steep Seattle lots?

Yes. We build raised and multi-level decks on sloped lots. If your property is in or near a steep-slope or landslide-prone area, SDCI requires a pre-application site visit before any permit, and the deck may need an engineer. We check the ECA map for your address before pricing.
