When I was moving out of my building I asked them to clariy on 30days vs a month & also leavin before my contract is up. What the lady told me was that as a DC tenant I have the right to only give 30 days, no matter if it was before me contract term, WITHOUT penalty. So I gave my notice on Jan. 15 stating I would be out by Feb. 15…..but because I was more than half way through feb. I was still financially responsible for the whole month. So I just left at the end of February, got my full deposit back and NO penalties. If they give you any guff, DC offers free legal assistance for tenants through the LEGAL AID ORG. hope this helps & wasn’t confusing.
