Multi-level wooden deck between urban buildings, showcasing unique architectural design.

What this work really involves

Deck failures in the Pacific Northwest are almost always water failures at the ledger, not wood failures in the field. The connection where a deck attaches to the house has to be flashed, fastened with the right hardware at the right spacing, and kept away from rim joist rot.

Add a roof and the project becomes structural: posts carrying a roof load need their own footings, the tie-in changes the drainage of the existing roof, and the covered area may count toward lot coverage.

Permit path

Building permit for decks over 30 inches above grade or attached to the house; footing, framing and final inspections; electrical sub-permit for lighting and heaters

What is included

  • 01

    Ledger detail

    Flashing, fastener type and spacing, and removal of siding to inspect the rim joist before attaching anything to it.

  • 02

    Footing design

    Depth, diameter, bearing and hardware, with an inspection before the pour is covered.

  • 03

    Guard and stair compliance

    Guard height, baluster spacing, graspable handrails and consistent riser heights, checked before final.

  • 04

    Drainage

    Under-deck drainage, downspout routing and where water goes once it leaves the covered area.

  • 05

    Roof structure

    Where covered, a framed roof with its own load path, tied into the existing roof with proper valleys and flashing.

  • 06

    Lighting and heat

    Wet-rated fixtures, GFCI circuits and, where wanted, gas or electric heating with the clearances it needs.

How the stages run

  1. 01

    Design and siting

    Three to five weeks. Size, height, access and how it reads from inside the house.

  2. 02

    Permit

    Four to twelve weeks. Covered structures take longer than open decks.

  3. 03

    Footings

    One to two weeks including inspection.

  4. 04

    Framing

    Two to four weeks, including ledger, posts, beams, joists and the framing inspection.

  5. 05

    Decking and rails

    Two to three weeks.

  6. 06

    Roof, finishes and final

    Three to six weeks where a cover is included.

What moves the price

Height above grade
Anything over 30 inches needs guards and, usually, a permit.
Covered or open
A roof changes the footing sizes, the permit path and often the lot-coverage calculation.
Decking material
Cedar, composite and hardwood differ in price, span and long-term maintenance.
Slope and access
Steep Eastside lots need longer posts, sometimes lateral bracing, and hand-dug footings.
Existing rim condition
Rot found when siding comes off is a repair before anything is attached.

Two things we will always tell you

A deck attached with lag screws into a rotten rim joist is a life-safety issue. We always open the siding and look before we price the ledger.

If a covered deck pushes the lot over its coverage limit, an open pergola with a slatted top is often the workaround.

Answers

Decks and outdoor living: common questions

Generally not if it is under 30 inches above grade and not attached to the house, but jurisdictions differ. We check before assuming.

Cedar looks better and needs refinishing every two to three years. Composite needs almost nothing and never looks quite like wood. Both are valid.

Yes. Footing pours need temperature protection, and framing lumber gets covered, but winter deck work is normal here.

We frame on footings after the required cure and the inspection, typically about a week after the pour.
