CHAS vs ACS for housing problems

I'm wondering if anyone is familiar with the CHAS data set (a special tabulation of ACS data for HUD). 

I'd prefer to use ACS data directly to calculate the CHAS estimate of housing problems (defined as a housing unit experiencing 1 of 4 housing problems including overcrowding, cost burden, lack of plumbing, or kitchen facilities). However it seems like CHAS is the only way to do so because it offers a unique count of the units experiencing at least 1 of 4 housing problems, where with ACS data there's potential overlap in the count of households (since they're separate questions). For example tabulating from ACS, if a unit had lack of plumbing, crowding and was cost burdened, it would appear that 3 units had problems whereas it should be counted as a single unit, having at least 1 of the 4 problems.

My conclusion was that CHAS avoids this and therefore I shouldn't/cannot use ACS, but I'm wondering if there's a way around it? Anyone else have experience with CHAS and know if I'm on the right track?
