i think the utilities rate is base on the usage if you refer to tnb and syabas website,
they are many apartment built on commercial title but utilities still base on resi rate.

same, if a landed house (resi title) but used as showroom (commi), the utilities will then base on commi
so, if the building eg soho,service apartment is use as resi , the utilities shud be resi rate too

i think the rate is base on usage as per their website

“Domestic Consumer” means a consumer occupying a private dwelling, which is not used as a hotel, boarding house or used for the purpose of carrying out any form of business, trade, professional activities or services.

yes agreed, especially strata property where initially it was bulk meter (under developer name), but once upstair resi have individual strata title have been issued, it should be able to covert to resi rate, the meter now transferred from the developer 's master title to individual title.
