$200-300/mo is the going rate for off street parking. What's more crazy is that on street parking is as cheap as it is. It's heavily subsidized and takes up a ton of valuable real estate.

Pretty much all the new walkable and high density developments like NoMA, Navy Yard, etc are not eligible for RPP. The math simply doesn't work to have high rises park their hundreds of cars in the 15 or less curb spots surrounding the building. Not to mention, having residents cars sitting curbside is horrible for creating a walkable business friendly neighborhood. If they want parking, needs to be underground. And most buildings only have parking for 1/3 of residents as that's all that's required by the city.

If you want to keep your car AND live downtown, you'll have to start paying the true cost of storing it in a city. Over a 3rd of DC residents get by car free just fine. And I would guess around 50%+ pay the monthly rate to store their car for no reason or to use it once a month or so.
