Decks Built for Business — and Built to Last

Commercial Deck Projects in Washington

Built to Code, On Budget, and On Brand

Deck Construction for Restaurants, Rooftops, and More

Whether you're expanding a restaurant patio, building a rooftop deck, or creating a foot-traffic-friendly outdoor space, we’ve got you covered. Our team builds commercial-grade decks that meet Washington code, hold up to daily use, and elevate the look and function of your property.

Foot Traffic. Fire Code. Function. We Cover It All.

Safe, Smart, and Stylish Decks for Commercial Properties

We understand the demands of business use — and we build to meet them. That means strong framing, durable surfacing, ADA-compliant access, and safe exits. We coordinate with architects and property managers to build decks that look great and perform under pressure.

  • Elevated, rooftop, and ground-level builds

  • Drainage, fire-rating, and load planning included

  • Framing for bar rails, seating zones, and lighting

More Than a Build — It’s a Business Asset

We Create Outdoor Spaces That Drive Revenue

For restaurants, breweries, wineries, and event venues, a well-built deck adds real value. We design for customer flow, furniture zones, and safety — with materials that last through every season. Whether you're seating guests or hosting events, your deck will support your business goals.

Deck Framing That’s Built for the Real World

We Engineer for Weight, Wear, and Weather

Commercial decks require serious structure — often with higher loads, waterproofing needs, or fire resistance. We use pressure-treated framing, hardware that handles crowds, and surfacing that stands up to sun, rain, and spills. Rooftop? Side lot? Second story? We’ve built them all.

Designed for Customers — and Built for Code Inspectors

We Handle All Permits, Plans, and Inspections

Commercial projects come with extra red tape — and we’re ready for it. We submit engineered plans, pull the right permits, and meet with inspectors so you don’t have to. Whether you're under city regulations or dealing with a tight downtown footprint, we keep your build compliant and on schedule.

Why Washington Businesses Trust Our Deck Builds

  • Engineered for Heavy Use: We build framing systems designed for weight, movement, and wear.

  • Code-Compliant Every Time: ADA access, stair specs, railing height — all built to local code.

  • Built for Wet Weather: Water-shedding systems and slip-rated decking keep your guests safe.

  • Commercial-Grade Railings: Cable, metal, glass, or composite options that meet public use standards.

  • Scalable for Growth: Expand your deck later — we design for future phases if needed.

Don't worry, we can help!

Smart Details That Make Every Deck Work Harder

From raised platforms for musicians to tucked-away storage under the deck, we build commercial spaces that support service and operations. Want built-in seating, host stands, or planter boxes? Done. We make sure your outdoor area works as hard as your team does.

  • Framing for benches, railing bars, or canopies

  • Compatible with heat lamps, lighting, and AV wiring

  • Hidden hardware and sealed surfaces for easy cleaning

One Team. One Contract. One Call to Make.

We’re Your Design + Build Partner from Day One

You don’t need to juggle a designer, framer, permit tech, and inspector. We do it all — with one contract, one price, and one point of contact. From layout to inspection, we’re here to keep your commercial deck build simple, on time, and on budget.

Building for Business? Start With the Right Info

What Commercial Clients Ask Before We Start

Building a deck for public or commercial use brings smart questions — and we’re ready with straight answers.

Question 1: Can you build a rooftop deck on a flat-roof building?

Yes — we assess the load limits, waterproofing, and structural tie-ins before framing.

Question 2: What’s the best decking material for a restaurant patio?

Composite is a top pick for its durability, stain resistance, and low maintenance.

Question 3: Can you meet ADA or fire code on public decks?

Absolutely. We handle everything from ramp slope to railing height and exit planning.

Question 4: Will I need to close my business during the build?

Not always. We schedule work to limit disruption and maintain safe access when possible.
