I'm assuming Hacker Dojo does not actually own the building and is leasing the space. Why isn't the building owner being held at least partially accountable for bringing the space up to code? I'm guessing it wasn't detailed in their lease, but how long is the lease for? Is there a possibility of breaking it and finding a building that does meet the requirements for how they want to use it?
Also, in most jurisdictions I've worked in, requirements to bring bathrooms up to ADA are not triggered unless you're already doing renovations over a certain amount in the building. Maybe here it's because the use type of the space is changing, though.
