Oh fuck. Hackerspaces tend to be ad-hoc repurposed/disused industrial or commercial spaces that tend to overlook fire, health/safety, and disability building compliance. City bureaucracies find out about these spaces and then drop an angry hammer on their heads with a laundry list of expensive mandatory changes. They don't want another Ghost Ship fire where almost half of occupants died (not a hackerspace, but a live-in art studio and improvised concert venue).

PSA: If you ever want to live with 10-20 other people in semi-illegal collective housing in an old factory, try not to make it an electrical or flammable death trap with fire drills and following proper building codes with layers of sensible preventative choices for living in something undocumented. Less wood framing (metal 2x4"s are customary in the US for interior, nonloadbearing walls) and flammable materials, less toxic substances, and proper conduit armoring and system grounding.
