A major property tax dispute has erupted in Chennai’s Mogappair West, where residents of a large apartment complex have alleged that the Greater Chennai Corporation (GCC) incorrectly recorded the sizes of their flats, resulting in significantly higher property tax assessments.

According to the residents, the discrepancies came to light when homeowners compared their latest property tax assessment notices with the measurements mentioned in their registered sale deeds and builder documents.

The issue affects around 1,840 apartments, with residents estimating that the incorrect assessments are collectively costing them an additional ₹30 lakh every year in property taxes.

Flats Allegedly Measured Much Larger Than Their Actual Size

One of the examples highlighted by residents involved a flat with an actual size of 1,062 sq ft, which was reportedly assessed by the Corporation as 1,498 sq ft.

The recorded area was nearly 41% larger than the actual size of the apartment.

Residents claim that several flats in the complex were similarly overestimated, leading to substantially higher tax demands.

Why Does an Increase in Square Footage Matter?

In Chennai, property tax is calculated based on several factors, including:

• Built-up or plinth area;
• Location of the property;
• Nature of usage (residential or commercial); and
• Classification of the building.

Since the built-up area is one of the primary components in determining the property’s annual value, any increase in the recorded square footage directly increases the tax payable.

Even a few hundred extra square feet reflected in municipal records can substantially increase the annual tax burden on homeowners.

How Did the Discrepancy Come to Light?

Residents reportedly discovered the issue after comparing:

✔ Registered sale deeds

✔ Builder agreements and floor plans

✔ Existing property tax records

✔ Recent assessment notices issued by GCC

The mismatch prompted residents to raise objections with the civic body, arguing that the Corporation’s records did not reflect the actual dimensions of their apartments.

GCC Agrees to Physically Remeasure the Flats

Following complaints and public backlash, the Greater Chennai Corporation has agreed to conduct a physical remeasurement of the properties in the presence of homeowners.

The exercise is expected to:

• Verify the actual built-up area of each flat;
• Correct any erroneous entries in municipal records;
• Revise property tax assessments where necessary; and
• Consider adjustments or refunds if excess tax has already been collected.

The decision has been welcomed by residents, who have been seeking corrections to what they describe as an unjustified increase in their property tax liability.

What Could Have Caused the Error?

While GCC has not publicly disclosed the exact reason behind the discrepancies, experts point to several possible causes:

1. Data Entry Errors

Incorrect information may have been entered during digitisation of property records.

2. Confusion Between Different Area Measurements

There is often confusion between:

• Carpet Area
• Built-up Area
• Super Built-up Area

Recording the wrong type of measurement can significantly alter the tax calculation.

3. Migration of Legacy Records

Errors may have occurred while transferring older records into newer digital assessment systems.

4. Survey and Measurement Mistakes

Incorrect measurements during previous inspections or assessments could also have contributed to the issue.

What Should Property Owners Learn From This?

The Mogappair incident serves as an important reminder for property owners across Chennai to periodically verify their municipal records.

Homeowners should compare the area recorded in their property tax assessment with:

• The registered sale deed;
• Approved building plans;
• Builder documents; and
• Previous assessment records.

Any discrepancy should be immediately brought to the attention of the Corporation to avoid paying excess taxes.

Can Homeowners Challenge Incorrect Property Tax Assessments?

Yes. Property owners can submit representations and supporting documents to the concerned Corporation authorities if they believe their assessments contain errors.

Documents that can help establish the correct area include:

• Registered Sale Deed;
• Approved Building Plan;
• Completion Certificate;
• Previous Property Tax Assessment Orders; and
• Builder’s Allocation Statement.

The Mogappair case demonstrates the importance of maintaining accurate property records and regularly reviewing tax assessments, especially as civic bodies increasingly rely on digitised data.

Opposition to the proposed Waste-to-Energy (WTE) project at Kodungaiyur has intensified once again, with resident welfare associations and civic groups from North Chennai preparing to seek Chief Minister Vijay’s direct intervention to withdraw the project.

The Federation for North Chennai Residents’ Welfare Associations (FNCRWA) stated that it plans to meet the Chief Minister, who also holds the Municipal Administration portfolio and represents the Perambur constituency, to press for the cancellation of the proposed waste incineration-based power project.

According to the federation, the issue is no longer just about waste management, but about the growing environmental and public health burden already faced by North Chennai residents.

Longstanding Concerns Over Pollution And Public Health

The proposed WTE facility at Kodungaiyur has faced resistance from sections of residents, environmental groups, and civic associations over the past few years. Opponents of the project have consistently raised concerns regarding:

• toxic emissions
• fly ash generation
• groundwater contamination
• respiratory health risks
• cumulative pollution exposure

Residents argue that North Chennai has already been subjected to decades of environmental stress due to industrial activity, thermal power infrastructure, petrochemical operations, and large-scale waste dumping.

Residents say areas like Manali, Ennore, Tiruvottiyur and Kodungaiyur have been facing most of Chennai’s pollution and industrial impact for many years, as North Chennai is repeatedly being chosen for pollution-causing projects. So now the residents are raising concerns about the unfair environmental impact felt on this region.

GCC Infrastructure Works Earlier Halted Following Objections

Earlier this year, infrastructure works linked to the proposed project reportedly faced resistance from local residents and RWAs. This included objections to a proposed access road sanctioned by the Greater Chennai Corporation (GCC) within the Kodungaiyur dumpyard premises.

Following protests and public opposition, those works were halted, while biomining activities alone are currently continuing at the site.

The development showed that public opposition against the project is growing stronger and that resident groups are starting to influence major infrastructure decisions in the city.

Demand For A Separate Environmental Policy For North Chennai

One of the strongest demands emerging from the residents’ movement is the call for a dedicated environmental policy framework for North Chennai.

FNCRWA representatives have argued that as the region has evolved into a heavily industrialised “chemical hub,” it requires:

• Specialised environmental planning
• Stricter pollution monitoring
• Healthcare interventions
• Ecological restoration measures.

The demand signals a broader shift in the conversation — from opposing a single project to questioning the long-term environmental planning approach adopted for North Chennai.

Residents Push Decentralised Waste Management Alternatives

While opposing the WTE project, several resident groups have also proposed alternative waste management strategies centred around – decentralisation and source-level waste segregation.

Civic associations have earlier promoted the “Green Chennai Initiative” (GCI), which advocates:

• micro composting centres
• material recovery facilities
• household-level waste segregation
• decentralised organic waste processing
• sustainable zero-waste systems

Supporters of the initiative argue that decentralised waste management models can significantly reduce landfill dependency without relying on large-scale waste incineration projects.

The proposal reflects a growing preference among environmental groups for circular waste management systems that prioritise recycling, composting, and resource recovery over centralised burning-based disposal methods.

Political Change Raises Fresh Expectations

Resident welfare groups say the recent political transition has given them renewed hope that the long-pending demand to withdraw the project may finally receive consideration.

Representatives from civic associations believe that the direct involvement of the Chief Minister in municipal administration could open the door for fresh consultations and policy review regarding the future of the Kodungaiyur project.

As debates around urban sustainability, pollution control, and climate resilience become increasingly prominent in Chennai’s development discourse, the Kodungaiyur WTE issue is emerging as a significant test of how the city balances waste management needs with environmental and public health concerns.
