Are PVC&PET bacteria found inside homes?
If you read the Wikipedia article carefully, and the recent article in PNAS on improving the enzymes responsible for TET degradation, it is evident that Ideonella sakaiensis is the only example so far known of a bacterium that can use PET as an energy source. As it is a Japanese marine bacterium it will not be found in “domestic spaces”.

The requirement for an aqueous environment is presumably related to the need for the enzymes the bacterium secretes to gain access to the plastic and the products of the digestion to be reabsorbed, and perhaps also for access to essential nitrogen, not present in the plastics. The rarity of bacteria that have evolved this facility presumably relates to the ‘difficulty’ of the chemistry — or its difference from that involved in degrading other carbon sources — although there is some similarity to cutinase, the enzyme in certain fungi that can digest the cuticle of plants.
