The General Services Administration—the federal agency that leases and manages office buildings for the government—would have to work with the various federal agencies that rent that space to figure out how they can share buildings and rooms more efficiently instead of each agency having its own dedicated, often underused space. This means the GSA has to talk to these agency "tenants" about what's holding shared-space setups back, come up with rules to make more sharing possible, and figure out how to better use special-purpose spaces (like labs or storage areas) for this purpose. Within six months of the bill becoming law, GSA has to report to Congress on how this is going, so mainly this affects federal employees and the agencies they work for, not the general public directly, though it could eventually reduce government spending on office space.
