At the last complete count, Census 2011, slightly more than half of all households in the Chennai Corporation area lived in rented homes: 51.14%, against 47.22% who owned the house they lived in. Across urban Tamil Nadu the pattern was reversed, with 57.45% owning and 40.21% renting.
That figure is fifteen years old, and the houselisting phase of Census 2027 ran in Tamil Nadu in August 2026, so fresh numbers are on the way. Until they are published, these are the most reliable official measures of how Chennai lives: who owns, how crowded homes are, which amenities households have, and how much public housing the state has built.
Owners, tenants and crowding in 2011
Census 2011 counted 11,54,982 households in Chennai district, according to Table 18.7 of the Statistical Hand Book of Tamil Nadu 2022-23. The state had 1,85,24,982 households, just under half of them urban.
The percentages below come from a city profile compiled from Census 2011 houselisting tables for the Chennai Municipal Corporation, as it then was, with state-urban and all-India urban comparisons (India Smart City Profile: Chennai).
| Census 2011 indicator | Chennai city | Tamil Nadu urban | India urban |
|---|---|---|---|
| Households in owned homes | 47.22% | 57.45% | 69.16% |
| Households in rented homes | 51.14% | 40.21% | 27.55% |
| Households in congested homes | 39.96% | 38.91% | 32.94% |
| Tap water from a treated source within premises | 84.08% | 66.29% | 84.14% |
| Toilet within premises | 94.57% | 66.48% | 72.57% |
| Wastewater outlet connected to drainage | 97.27% | 74.94% | 81.77% |
| Electricity | 99.08% | 96.11% | 92.68% |
Chennai’s renting share was almost double the urban India average. “Congested” in census terms means a married couple did not have a separate room, so about two in five Chennai households were short of space. The profile also put the slum population at 28.89% of the city’s residents in 2011.
What changed by 2019-21
The National Family Health Survey is the most recent official snapshot of Chennai homes. Its district fact sheet is based on a sample of 743 Chennai households, so treat small differences with caution. It does not ask about ownership.
| Chennai indicator | NFHS-4 (2015-16) | NFHS-5 (2019-21) |
|---|---|---|
| Population in households with electricity | 99.7% | 99.9% |
| Improved drinking-water source | 98.0% | 98.7% |
| Improved sanitation facility | 82.7% | 90.4% |
| Clean cooking fuel | 96.7% | 97.7% |
The census and NFHS use different definitions, so the columns cannot be joined into one trend. The broad message is that basic amenities are close to universal, and that sanitation coverage improved through the late 2010s.
Public housing: 1.17 lakh tenements
For many lower-income families, the state’s tenements are home. The Tamil Nadu Urban Habitat Development Board policy note 2024-25 says the board has built 1,93,891 tenements since 1970 across 439 schemes. Chennai has 1,17,016 of them in 206 schemes, about 60% of the total.
| Public housing measure | Figure | Year |
|---|---|---|
| TNUHDB tenements in Chennai | 1,17,016 (206 schemes) | 2024-25 policy note |
| TNUHDB tenements statewide | 1,93,891 (439 schemes) | 2024-25 policy note |
| Cooum and Adyar families to be resettled | 23,796 (18,535 done) | 2024-25 policy note |
| Building plans sanctioned, Greater Chennai Corporation | 7,693 of 28,284 in 12 corporations | 2022-23 |
The resettlement line refers to families moved from the banks of the Cooum and Adyar under river restoration. The policy note recorded 5,261 families still to be resettled, with completion targeted for March 2025. North Chennai projects listed in the same note include 468 tenements at Water Basin Road and 776 at Stanley Road.
The building plan figure, from Table 18.2 of the handbook, counts private-sector plans approved by the Corporation in 2022-23. Chennai accounted for about 27% of all such approvals across the state’s 12 corporations that year. Larger projects approved by CMDA are not in this count.
Census 2027 houselisting
The first phase of the new census, the Houselisting and Housing Census, ran door to door in Tamil Nadu from 1 to 30 August 2026, after a self-enumeration window from 17 to 31 July, DT Next reported. More than 1.15 lakh enumerators used a mobile app with a 33-question schedule covering housing condition and amenities. Over 10 lakh households across the state filled in their details online before the field visits began.
When those tables come out, they will show for the first time in fifteen years how many Chennai households own, rent or share, and how amenities have changed in the newer parts of the Corporation that were added after 2011.
