Tamil Nadu is planning a major upgrade of urban housing and infrastructure in 2026–27, with thousands of new homes, redevelopment of old apartments and improvements to basic facilities. The Tamil Nadu Urban Habitat Development Board has announced several projects aimed at providing safer housing for vulnerable families while improving living conditions in existing apartment communities. The combined value of the initiatives covered here is more than ₹4,400 crore.
9,918 Old Apartments to Be Demolished and Rebuilt
One of the biggest announcements involves the redevelopment of 20 urban housing project areas. Technical committees have identified several apartments as being in poor condition.
In the first phase:
- 9,918 old apartments will be demolished
- 12,648 new apartments will be constructed
- Estimated project cost: ₹2,882.62 crore
The redevelopment is aimed at replacing unsafe and deteriorated housing with new apartments.
462 New Homes Planned in Perambur
In Perambur, Chennai, the Board will construct 462 apartments for families living along roadsides, in other objectionable locations and for poor and homeless families.
The project has an estimated cost of ₹111.08 crore.
₹2.5 Lakh Assistance for 15,000 Families
Under a beneficiary-led housing scheme, economically weaker families who own land but live in thatched houses will receive financial support to construct their own concrete-roofed homes.
The scheme provides:
- ₹2.50 lakh per family
- 15,000 houses
- Estimated project cost: ₹987.42 crore
- Implementation during 2026–27
This is particularly relevant for eligible low-income landowners who need financial support to replace temporary houses with permanent homes.
41,664 Existing Apartments to Get Repairs and Upgrades
The Government also plans to improve 41,664 existing apartments in Chennai and other districts.
The work will include repairs and improvements to:
- Roofs, floors and staircases
- Building exteriors and painting
- Electrical panels
- Drinking-water systems
- Sewage systems
- Community facilities
- Fair-price shops and Anganwadi centres
The estimated cost is ₹96.63 crore.
₹355 Crore for Basic Infrastructure
The Urban Habitat Development Board currently maintains 1,39,710 apartments across 208 project areas in Chennai and other cities.
Infrastructure improvements worth ₹355 crore are planned for these areas. The works will cover roads, footpaths, drinking-water supply, sewage systems, electrical safety and other essential civic infrastructure.
Housing Services to Go Digital
A new Tamil Nadu Integrated Smart Habitat Management Platform will also be developed at an estimated cost of ₹75 lakh.
The platform will bring several services online, including:
- Housing allotments
- Smart cards for beneficiaries
- Waiting-list management
- Housing-stock information
- Beneficiary records
- Grievance handling through an app
- Maintenance-fee collection
- Monitoring of Board activities

The 2026–27 announcements focus on three major areas: replacing unsafe housing, supporting new home construction and improving existing urban communities. Along with new apartments and individual houses, the planned infrastructure upgrades and digital services are intended to improve everyday living conditions for thousands of families across Tamil Nadu.
