Hotels in Chennai are pricier than elsewhere in Tamil Nadu and not particularly good value. The Triplicane area is known for budget accommodation, but much of it is pretty gritty. Better cheapies are found in Egmore, and there are a couple of good hostels in other neighbourhoods. You'll find upper-midrange B&Bs in Nungambakkam, Poes Garden and Alwarpet. Top-end hotels are plentiful. Many hotels fill up by noon – book ahead!
