Here's the deal: Ground Floor was a perfectly fine workplace rom-com that aired for two seasons on TBS in 2013-2014, got decent reviews, and then basically disappeared. The audience score is great (93%), so people who watched it enjoyed it, but not enough people watched it to keep it alive.

The bigger problem for parents isn't whether it's appropriate (it's fine for high schoolers who like romantic comedies) - it's that this show is basically unavailable and culturally irrelevant. It's not streaming anywhere major, it didn't leave a cultural footprint, and there are dozens of better, more accessible romantic comedies your teen could watch instead.

Unless your kid is doing a deep dive into obscure early-2010s sitcoms (why?), this one's not worth hunting down. It's the TV equivalent of that restaurant that was fine but closed after a year - maybe it was good, but there's a reason nobody remembers it.
