A new deck in Spokane typically costs $8,000 to $20,000 for a standard 300 to 500 square foot build using pressure-treated framing and composite or cedar decking. Smaller ground-level platforms start around $5,000. Covered patio additions add $6,000 to $15,000. Price depends on size, elevation, materials, and how many stairs and railing sections are included.
The four main cost factors are square footage, elevation, materials, and site conditions. A ground-level 200 square foot platform on a flat lot in Cheney costs far less than a multi-level 500 square foot deck on a South Hill slope with two stair runs and cable railing. Material is the second biggest driver: pressure-treated decking costs less upfront than composite, cedar sits in between. Permits add $300 to $800 to the total but are not optional in Spokane for most deck builds.
Pressure-treated lumber decking runs about $8 to $14 per square foot installed, which makes a 400 square foot deck roughly $3,200 to $5,600 for the surface boards plus framing labor. Composite boards (Trex, TimberTech) run $12 to $22 per square foot installed, putting a 400 square foot composite deck at $4,800 to $8,800 for the surface plus framing. Cedar falls in the middle at $10 to $18 per square foot. All prices include framing labor but not the permit fee or footings on challenging sites.
Frost depth in Spokane is about 18 to 24 inches, which affects footing costs on elevated decks. Elevated decks on South Hill and Five Mile Prairie often require longer posts and diagonal bracing that adds $500 to $2,000 to the framing cost compared to a flat-lot build. If a permit is required, the city review adds one to two weeks before framing can start but does not typically change the construction cost.
Deck pricing varies enough by site and layout that any number quoted without a site visit has a wide margin of error. We do free on-site estimates. We measure the space, discuss your material preferences, and leave you with a written number before any commitment. The estimate visit takes about 30 to 45 minutes and covers everything you need to compare options.
A ground-level pressure-treated deck with standard wood railing is the most cost-effective option. A simple 200 to 250 square foot ground-level platform can come in around $5,000 to $7,000 including framing, decking, and a basic railing.
Yes. A covered addition adds $6,000 to $15,000 on top of the base deck cost, depending on the span and roofing material. The cover requires its own permit drawings and structural engineering for the roof framing.
Spokane building permit fees for a residential deck typically run $300 to $800 depending on valuation. That is a small part of the total project cost and is not a reason to skip the permit, which protects your homeowner insurance and resale value.

We built this operation around one idea: a deck is a structural investment, not a cosmetic one, and it deserves the same care you would put into any other part of your home. We work across Spokane, South Hill, Five Mile Prairie, Mead, and the Spokane Valley. Every build gets a permit, pressure-treated or composite framing rated for the Pacific Northwest, and a final inspection before we call the job done. We give you a flat written estimate after the site visit and we stand behind the work with a workmanship warranty.
