Ozone Group in one paragraph
Ozone Group has a weak delivery record in Karnataka RERA filings: 44% of registrations needed no extension (3 of 8 crawled Bengaluru registrations needed no extension). 7 of 8 under-construction projects are past their original RERA completion date, by 35 months on average (worst 84). The promoter entity carries 541 complaints at K-RERA across its projects. The median Ozone Group project scores 48/100 on investment merit (below the Bengaluru average); the best, Ozone Chambers, scores 62.
Delivery is judged on extensions filed, not on handover dates, because RERA records extensions reliably and handovers late. Extensions are common across Bengaluru; compare the rate with other developers below.
