Tenant is in a wheelchair now requested move due to two stairs

[Troy Biggham]

My tenant who was injured somewhere and is now in a wheelchair is requesting a letter to break her lease. She is a voucher recipient and thus far a really good tenant ( 4 months). She has given me a move date but says she will give me a 30 day notice. I recently went into the unit and it is in great shape. My issue/rookie mistake is DC government was supposed to pay the security deposit but never did then when I questioned it they told me to get it from her. Needless to say I have no security deposit as of now the unit could be cleared and rented the next day but my worry is what if in her 30 days she trashed the place shadow I do. Do I try to accommodate her with a ramp fir the two stairs our will that open me up for more than I want to handle. Any insight would be appreciated
