Hundreds of urban families in Tamil Nadu moved a step closer to a permanent home on Wednesday, 4 November 2026, as Chief Minister Joseph Vijay inaugurated 643 multi-storey residential units and commercial complexes built by the Tamil Nadu Housing Board (TNHB) at a cost of ₹1,003.97 crore, alongside 125 apartments constructed by the Tamil Nadu Urban Habitat Development Board (TNUHDB) for ₹17.56 crore in the Kolathur project area — a combined investment of over ₹1,021 crore in state-funded urban housing.

What was inaugurated — and where

The larger of the two components, the 643-unit TNHB development, encompasses both residential apartments and commercial complexes, reflecting the board's model of pairing affordable housing with income-generating commercial spaces to sustain maintenance costs. The second tranche — 125 apartments in the Kolathur project area — is a TNUHDB initiative, the board specifically mandated to rehabilitate informal settlements and improve urban habitats across Tamil Nadu's city belts.

Together, the two completions add 768 dwelling units to Tamil Nadu's urban housing stock in a single inauguration, one of the larger single-day handovers under the state's current housing programme.

Tamil Nadu's multi-storey housing push

The TNHB and TNUHDB have been the twin engines of the state's affordable urban housing drive for decades. Tamil Nadu has consistently channelled state funds — often supplemented by central urban-development missions — into multi-storey projects that target both general low-income buyers and families displaced from informal settlements slated for redevelopment.

The Kolathur project area component is particularly significant: TNUHDB projects in designated project areas typically serve residents rehabilitated from older, structurally vulnerable housing clusters, making the 125-unit handover a direct quality-of-life upgrade for some of the city's most vulnerable urban families.

Scale of the investment and what comes next

At ₹1,003.97 crore for the TNHB tranche alone, the per-unit cost averages roughly ₹1.56 crore across a mixed residential-commercial portfolio — a figure that reflects both the vertical construction costs and the commercial-complex component bundled into the scheme. The TNUHDB's ₹17.56 crore outlay for 125 apartments works out to approximately ₹14 lakh per unit, consistent with subsidised rehabilitation-housing economics.

Occupancy timelines, maintenance arrangements, and announcements on follow-up phases of both boards' pipelines will be the immediate metrics to watch as allottees begin the process of taking possession.

For thousands of Tamil Nadu families who have waited years on housing board lists, Wednesday's ribbon-cutting is not a ceremony — it is a set of keys.
