The District: a local law that reaches further
The District is not a state, and its anti-discrimination ordinance is not a copy of the federal one. It protects a notably wider list of characteristics and is enforced by a city office that sits within a few miles of every property it covers.
Where the local ordinance goes further
The federal floor is the same everywhere. The District builds noticeably higher on it.
When both regimes cover the same facts, whichever grants more prevails over that ground. Nothing in the city code can subtract from the national minimum.
The District's housing, and what each type produces
When home and work are both in play
A very large share of District residents work for federal agencies or the organisations around them, and people frequently conflate two separate questions: whether an animal may live in their apartment, and whether it may come to the office.
They are decided under different rules by different bodies. The apartment is a residential question, answered under the wider standard, with no requirement that the animal be trained. The office is an employment question, answered case by case against the actual duties of the job, and a yes at home implies nothing at work.
Keep the two requests entirely separate. Mixing them into one letter tends to produce a single confused refusal covering both, rather than two answers you can deal with individually.
Where a District resident can take it
Unusually, several genuinely useful options within a few miles.
