drk5 is right. From personal experience, there’s no way in hell anyone could be evicted for being a few weeks late. My co-op successfully evicted someone via the normal court process and not only did it take close to a year, but afterward there were two further lawsuits in the landlord-tenant court from the evicted parties (a divorced couple) each trying to weasle their way back into the building. drk5 is spot-on about the absurb biases of the DC Landlord-Tenant court, and yes, the co-op/resident relationship is governed by the same laws and regulations as a landlord-tenant relationship. So, your friend shouldn’t be worried about being evicted, but should be worried about other deadbeats in the co-op and the near impossibility in DC of kicking *those* people out.
