Deck Builders in Puyallup: Costs, Permits, and Hiring

I do not rank deck builders, and I would be cautious of any site that does. What matters is knowing what a deck should cost, what the rules are, and how to tell a careful builder from a careless one. A deck is the one home project that can hurt someone if it is built wrong.

What a deck costs

Railings add $20 to $60 per linear foot and a set of stairs $1,400 to $2,600.

For a local benchmark, Remodeling magazine's 2025 Cost vs. Value report for the Seattle area prices a wood deck addition at $20,294 and a composite one at $28,639. Those are elevated decks with railings and stairs, which is what most sloped Puyallup lots require.

Wood or composite?

Whatever goes on top, the frame underneath is almost always pressure-treated lumber. In our wet climate, the frame is what determines how long the deck lasts.

Permit rules

Unincorporated Pierce County. The county's Work Exempt from Building Permit guide exempts a deck that is no more than 30 inches above grade at any point and is not over a basement or story below. A freestanding patio or deck cover up to 200 square feet is also exempt. A cover attached to the house needs a permit.

Anything higher than 30 inches needs a permit. The county publishes a predesigned deck guide that can simplify plan review.

City of Puyallup. Check with the city's permitting office before building.

On a sloped lot, measure carefully. A deck that is 18 inches off the ground at the door can be 5 feet up at the far edge. The rule is 30 inches "at any point."

Setbacks, septic drainfields, and critical areas apply whether or not a permit is needed.

How decks fail

Understanding this helps you judge a builder.

• The ledger. Most collapses happen where the deck attaches to the house. The ledger board should be bolted or structurally screwed to the framing, never just nailed, and flashed so water cannot get behind it.
• Footings. Too small, too shallow, or sitting on fill.
• Railings. Loose posts and wide gaps. Guardrails are required on decks more than 30 inches high.
• Stairs. Uneven risers and weak stringers.
• Rot. Posts buried in soil and joists with no airflow.

Ask a builder how they attach and flash the ledger. A good one will have a detailed answer. A vague one is a warning.

How to hire a deck builder

1. Get three written bids with the same size, materials, railing, and stairs. That is the state's own advice for hiring any contractor.
2. Verify the company. Look it up in the Department of Labor and Industries' Verify a Contractor tool to confirm registration, bond, and insurance.
3. Ask who pulls the permit. It should be the builder.
4. Ask for addresses of decks they built five or more years ago, and go look.
5. Get the details in writing: footing size and depth, joist spacing, ledger attachment, fastener type, and decking brand.
6. Tie payments to progress. Never pay in full before the final inspection.

Before anyone digs

Call 811 for a free utility locate. And know where your septic tank and drainfield are if you have them. A deck footing through a drainfield line is an expensive mistake.

Existing decks and selling

An older deck is one of the most common items on an inspection report. Before listing:

• Tighten or replace loose railings
• Replace rotted boards and wobbly stair treads
• Check the ledger attachment and flashing
• Pressure wash carefully and reseal

If the deck was built without a permit and is over 30 inches high, expect questions. It is better to learn that before a buyer's inspector does.

Does a deck add value?

Among bigger projects, it does better than most. A wood deck recovers about 83% of its cost in Seattle-area data and composite about 80%. Usable outdoor space also photographs well and gives buyers a place to picture themselves on a July evening.

Frequently asked questions

How much does it cost to build a deck in Puyallup?

National guides put it at $25 to $50 per square foot for pressure-treated wood and $40 to $80 for composite. Seattle-area benchmarks are about $20,300 for a wood deck addition and $28,600 for composite.
