Apartments without power backup options

Q: Almost all apartments builders provide DG power backup options with an additional charges hovering around 1.5L. This is totally unnecessary since a 1-1.5KVA home UPS will be available for around 20K including the cost of battery. Also, in case of a power cut, the changeover is much faster in case of UPS than that of a DG with most of the power cuts in Bangalore lasting no longer than 5-10mins. Most of the apartments charge exhorbitant maintenance charges in the range of Rs.2/sq.ft. per month. I feel apartments without these unwanted features will cost less upfront and also maintenance charges will be low. Could anybody suggest such no-frills apartment projects in Bangalore in the price range of 40L for a 3BHK.
