floor covering

we are a two flat condominium
i'm downstairs..i know there are tons of postings about floor covering but my question is about what kind of floor is considered wood floors.
the upstairs owner pulled the carpets from all of the rooms except the bedroom and partially covered them with rugs.
our CC&R dictates 75% coverage BUT the exposed wood floors are not hardwood. They're sub floors made of douglas fir. They have gaps between the wide planks so we can hear almost everything that's going on in each room even with the rugs down.
Can we force them to cover the sub floors with the usual layer of sound deadening and a regular hardwood floor?

Thanks for this..
I think I misspoke...I'm calling this a subfloor because there's no other structural floor and it seems as tho
it's unfit for a finished floor- is that correct?
The house was built in the early 1900's and the floors (as well as most of the construction) is Douglas Fir.
As in many old houses the noise factor is an issue. Our CC&R dictates a certain amount of floor covering
to mitigate some noise but I submit that if the original wood floor was covered with a layer of soundproofing material and THEN some hardwood planks - there would be much less sound coming thru the floors.
Do you think we have a case re asking the owners to either put down hardwood and/or cover the existing floor with larger rugs?
