Restaurant and rooftop decks built for crowds, not backyards.
Patio season is revenue in metro Detroit, and the structures under it carry the heaviest duty the code recognizes. Detroit Deck Rebuild builds and rebuilds hospitality decks to assembly loads, on the off-season calendar, at published prices.
What hospitality work includes
- Patio deck rebuilds: grade-level and raised platforms reframed to the 100 pound per square foot assembly standard, with drainage and surfaces that survive service traffic.
- Rooftop decks: engineered load paths into the existing building, waterproofing that protects the space below, and the egress and occupancy work assembly spaces require.
- Guards and rails: crowd-rated guard systems that pass the shake test and the inspector, in wood, aluminum, or steel to match the room.
- Ramps, stairs, and access: the accessibility and egress pieces that patio permits actually hinge on, built into the design instead of bolted on after.
- Waterfront decks: Lake St. Clair exposure detailing, wet-rated framing and stainless hardware, for the properties where the water is the draw.
The calendar is the strategy
Every hospitality deck project has a free version and an expensive version of itself. The free version demolishes in November and opens in March, with framing running through the cold months the way Michigan construction always has. The expensive version loses summer weekends to construction fencing. Operators along Royal Oak’s Main Street and Ferndale’s 9 Mile strip who book by early fall get the free version, and we hold the off-season calendar for exactly that.
Why assembly loads change the design
A hundred people standing shoulder to shoulder is a live load residential framing was never asked to imagine, and the code numbers reflect it: double the design load, concentrated loads on guards, and egress sized for the crowd. That is why our hospitality rebuilds start from span tables and engineering rather than from what the old deck happened to be. The structure underneath a good patio should be the most boring thing about it.

Operator questions, answered straight
What does a restaurant deck rebuild cost in metro Detroit?
Commercial deck rebuilds run $45 to $85 per square foot engineered and permitted, so a typical 800 square foot patio deck lands between $36,000 and $68,000 and a 400 square foot bar platform between $18,000 and $34,000. Rooftop projects add 15 to 35 percent for access and membrane protection. The published cost guide breaks out guard-only and partial scopes that come in far lower.
What load does a restaurant deck have to carry by code?
Assembly areas, which is what seated and standing crowds are, design to a 100 pound per square foot live load under the building code, versus 40 for residential decks. Guards must resist real concentrated loads at the top rail. A deck built residential-style under a bar is undersized by more than half, which is why commercial rebuilds reframe rather than patch.
Can the deck be rebuilt without losing patio season?
Yes, if the calendar leads: demolition after the season closes, framing through the winter (Michigan cold does not stop structural work), and completion before the first warm weekend. Off-season slots book from late summer, and an operator who calls in August gets the schedule that costs zero revenue.
Can an older building support a rooftop deck?
Often, and the honest path starts with opening a small section of roof and looking at the framing. The structural verdict drives the design: where the existing structure can take the loads, where new posts and beams must carry them, and what the waterproofing under the deck needs to protect the business below. An hour of exploratory work up front prevents the mid-project surprise that wrecks budgets.
Detroit Deck Rebuild also runs multifamily balcony programs and facility condition assessments, with every number on the published cost guide and the whole operation at the homepage.
