@Rachna,
As far as I have seen in the DDA 2010 scheme Brochure (pg
5) ,the items covered and stated under 30 Yrs maintenance are civil works like
white wash,Grit wash,plaster, maintenance of railings,floors,drains line of
common areas and some kinds of civil repairs .
They do not mention any services like electrical ,
cleanliness , gardener , sweeper etc.
Further at para 20 at pg 7 of the brochure, it has been stated that other maintenance ,services for common areas apart from the works covered under the 30 year maintenance would be proved by RWA of which residents should be members.
So legally speaking DDA has already specified what its responsibilities are and which others will lie with the RWA.
Is this mentioned somewhere else?Can you please cite or provide
the source in case you have seen it.
The services apart from civil works that you mention normally
come under purview of RWAs in other colonies,including the earlier DDA ones.
So as far as I understand, there does not appear to be any basis for any legal action against the DDA.
Though, I would be happy to be corrected.
