House Construction Cost in Chennai — 2025 Rates
Chennai's construction costs sit at the higher end among South Indian metros, reflecting strong workmanship standards and periodic sand-supply constraints, partly offset by port access for other materials. CMDA governs planning permission and TNCDBR 2019 governs building rules, with OSR (open-space reservation) requirements on larger layouts. A standard-finish home builds at roughly ₹1,950/sqft.
