Under-Construction Flats in Chennai — 2026 Market Overview
Propspedia lists 300 under-construction flats in Chennai in 2026, priced ₹15L–₹8.8 Cr — averaging ₹11,713/sqft. Buying under construction means entering ahead of ready-possession pricing and paying on a construction-linked schedule rather than the full amount upfront, in exchange for a wait of typically 1–3 years and 5% GST on the purchase (1% for qualifying affordable housing) that a completed flat with an Occupancy Certificate does not attract. Under-construction supply in Chennai is concentrated in Madhavaram, Kelambakkam, Anna Nagar, Kundrathur, Navalur. The single non-negotiable check: buy only TNRERA-registered projects — registration obliges the builder to hold 70% of collections in escrow, publish quarterly construction photo updates, and pay 10.5% annual interest on any delay past the committed date. Verify the registration number at tnrera.in before paying a booking amount.

FAQs — Under Construction Flats in Chennai
What is the price of under-construction flats in Chennai?
Under-construction flats in Chennai are priced ₹15L to ₹8.8 Cr — averaging ₹11,713 per sqft across 300 verified listings on Propspedia. Most active under-construction zones: Madhavaram, Kelambakkam, Anna Nagar, Kundrathur. Entry pricing typically runs below an equivalent ready-to-move flat in the same location.
Is it safe to buy an under-construction flat in Chennai?
Yes, if the project is TNRERA-registered. Registration obliges the builder to hold 70% of collections in escrow, publish quarterly construction updates with photos, and pay 10.5% annual interest for delays past the committed date. Never book an under-construction flat without verifying the registration number at tnrera.in.
Is GST applicable on under-construction flats in Chennai?
Yes — 5% GST applies (1% for qualifying affordable housing: carpet area up to 60 sqm and a price up to ₹45 lakh). GST is nil once the builder receives the Occupancy Certificate, which is why ready-to-move flats are cheaper net of tax than the headline price alone suggests.
What payment plans are available for under-construction flats in Chennai?
Common plans: Construction-Linked Plan (CLP, payments tied to physical milestones — the safest and TNRERA-recommended), Down Payment Plan (most upfront for a discount), and Possession-Linked Plan (balance on handover). Avoid any plan that front-loads payments ahead of matching construction progress.
