FAQ
Common questions about OMR IT Corridor Chennai
Which OMR sub-zone is best for a mid-size GCC: Perungudi, Sholinganallur or Siruseri?
Perungudi (0 to 8 km on OMR) offers ELCOT SEZ benefits and shortest city distance but highest rents. Sholinganallur (15 to 25 km) provides the best balance of rent, talent density and residential proximity. Siruseri (40 to 45 km) offers the lowest rents and large floor plates (TCS model) but requires a standalone campus strategy with on-site amenities. For a mid-size GCC (200 to 1000 seats), Sholinganallur-Thoraipakkam is typically the optimal choice.
How has the Zoho-Freshworks ecosystem impacted OMR talent quality?
Zoho Corporation (3,000-plus products, 100 million-plus users, private and profitable) and Freshworks (NASDAQ-listed, Chennai-founded) have demonstrated that Chennai can produce world-class product companies, attracting engineers who choose Chennai specifically for product engineering careers. This has shifted OMR talent from purely IT services delivery to include product-native engineers who have worked at Zoho, Freshworks, or their supply chain - a talent cohort now available for GCC hiring that did not exist 10 years ago.
What is the flood risk on OMR and how do GCCs manage it?
OMR has experienced significant flooding during Chennai's northeast monsoon (October to December) in 2015, 2021 and 2023, with some stretches inundated for 1 to 3 days. GCCs on OMR now universally implement 3 to 5 day monsoon business continuity protocols: remote work infrastructure, generator-backed data centre connectivity, and staff transport plans. SIPCOT Siruseri is on elevated terrain and less flood-prone than the lower-lying Sholinganallur stretch.
