Less than most people think. Vinyl-sided buildings need almost nothing. A hose-down once or twice a year keeps them looking clean. Painted wood or LP SmartSide benefits from a fresh coat of paint every 5 to 7 years depending on sun exposure and weather. Metal roofs are virtually maintenance-free.
The two things worth checking annually: make sure the ground around the building still drains properly and that no debris is piling up against the base. Clear any leaves or branches off the roof after fall. That's about it. These buildings are built to be low maintenance, and they deliver on that.
