Converting garage rooftops to usable space
Chicago lots are tight, but that flat garage roof represents untapped potential—often 400 to 600 square feet of usable outdoor space sitting empty. Converting a garage top into a rooftop deck gives you private outdoor living in a city where ground-level yards are a luxury, adding functional square footage and real property value to your home.
Garage roof decks require serious structural work. Chicago code mandates a minimum 60 PSF live load capacity, verified by a licensed engineer. Most detached garages need foundation reinforcement—concrete work, steel framing, proper drainage integration, and fire-rated construction near property lines. We handle the engineering assessments, permit applications, and the structural upgrades needed to build safely and to code.
Access makes or breaks a garage deck. We design direct connections from your home—stair towers, bridges from upper floors, or exterior stairs with proper railings—so your rooftop space is convenient and safe to use daily, not just an afterthought you rarely visit.
