Types of Commercial Decks We Build


Outdoor dining has become essential for many restaurants. We build dining decks that accommodate maximum seating, meet health department requirements, provide ADA accessible routes and seating, and create inviting atmospheres.

Bar and Brewery Decks

Bars and breweries benefit from outdoor gathering spaces.


What we design for:



  • Standing crowds and social gatherings
  • Bar service areas and drink rails
  • High traffic volumes
  • Spaces that become destinations

Rooftop Decks

Rooftop decks maximize space in urban locations. These projects require specialized expertise.


Technical requirements:


  • Structural load calculations
  • Waterproofing and drainage
  • Access and egress requirements
  • Wind and weather considerations


We work with structural engineers to ensure rooftop decks are properly supported and coordinate waterproofing to protect the building below.

 Hotel and Resort Decks

Hotels and resorts use decks to create outdoor amenity spaces. We build pool decks that handle moisture and chemicals, gathering areas for events and socializing, and connected deck systems that link different outdoor zones.

Commercial Decking Materials


Material selection for commercial decks balances durability, maintenance requirements, looks, and budget.


Timbertech Advanced PVC is our top recommendation for commercial decks.

Why it works for commercial use:


  • Handles high traffic without showing wear
  • Resists staining from spills and food
  • Stays cooler underfoot than many composites
  • Requires minimal maintenance
  • Slip resistant when wet
  • Won't splinter


For restaurants and bars, low maintenance is critical. You don't have time to close for days while the deck is sanded and restained. Timbertech Advanced PVC just needs occasional cleaning to look great year after year.


We build all commercial deck frames with KDAT (Kiln Dried After Treatment) lumber. The dimensional stability of KDAT lumber is even more important in commercial applications than residential.


Westbury aluminum railing systems are excellent for commercial decks. They're strong, won't corrode or deteriorate, require minimal maintenance, and meet all code requirements for height and spacing. They also look professional and modern.

Commercial Deck Design Considerations


Every square foot of deck space represents revenue potential. We design commercial decks to maximize usable area while maintaining comfortable traffic flow.

Design strategies:



  • Multi level designs that create distinct seating zones
  • Strategic placement of stairs and ramps to preserve seating area
  • Creative layouts that work around existing site constraints
  • Efficient use of every available square foot


Traffic Flow and Safety


Customer safety is paramount. We design commercial decks with these considerations.


Safety features:


  • Clear paths to exits
  • Adequate spacing between tables
  • Slip resistant surfaces throughout
  • Proper lighting for evening use
  • Server paths for efficient movement


Weather Protection


Wisconsin weather is unpredictable. Extending your usable season means providing weather protection.


Options we can incorporate:


  • Pergolas for partial shade and rain protection
  • Roof structures for full coverage
  • Windbreaks and privacy screens
  • Heating options like radiant heaters


Maintenance and Longevity


Commercial decks need to look good year after year with minimal downtime for maintenance. Timbertech Advanced PVC requires only periodic cleaning. No sanding, no staining, no sealing. This means minimal disruption to your business for deck maintenance.

Built to last:

  • Proper drainage to prevent standing water
  • Quality fasteners that won't loosen
  • Structural designs that distribute loads evenly
  • Materials that handle constant traffic


Many of our commercial clients operate their decks for years with nothing more than occasional cleaning.

What Makes Commercial Deck Building Different

Commercial decks face challenges that residential decks don't. Understanding these differences is critical to building decks that last.

  1. Higher Traffic Volumes

A residential deck might see a few dozen people per week. A busy restaurant deck sees hundreds of customers per day. This constant traffic puts tremendous stress on decking materials, fasteners, and structural components.


How we build for high traffic:


  • Heavier duty framing with closer joist spacing
  • Commercial grade fasteners that won't loosen
  • Decking materials proven to handle traffic without wearing out
  • Structural designs that distribute loads evenly

2. ADA Compliance Requirements

Many commercial decks must meet Americans with Disabilities Act requirements for accessibility.


ADA requirements include:


  • Ramp slopes at maximum 1:12 ratio
  • Minimum 36 inch clear width for ramps
  • Proper landing sizes and configurations
  • Handrails at correct heights with proper design
  • Slip resistant surfaces


We're experienced with ADA requirements and design commercial decks that provide full accessibility while maintaining good looks. Getting ADA compliance right the first time prevents costly modifications later.

3. Building Code and Permitting

Commercial projects face stricter building code enforcement than residential work. Inspections are more rigorous, documentation requirements are more extensive, and there's zero tolerance for shortcuts.


What we handle:



  • All permitting and inspections
  • Full compliance with Wisconsin commercial building codes
  • Coordination with local building departments
  • Proper documentation at every stage


Our commercial decks pass inspection the first time because we build them right.

4. Timeline and Business Disruption

Every day of construction affects your business. We understand that minimizing disruption is critical, especially during peak season.


Our approach:


  • Detailed project scheduling for efficient completion
  • Off hours construction when possible
  • Clear communication about timelines
  • Efficient crews that work quickly without sacrificing quality
