Ministerial Approval Requirement Removed

Previously, proposals for high-rise buildings exceeding 18.3 metres in height had to pass through two main levels:

1. The proposal was examined by a committee chaired by the CMDA Member Secretary.
2. Even after committee clearance, the file had to be forwarded to the Tamil Nadu government for final approval by the minister, who served as CMDA chairman.

Under the new system, CMDA can directly approve the proposals, so the files no longer need ministerial clearance. This is expected to reduce such delays.

This change was introduced through a Housing and Urban Development Department government order G.O. (Ms) No.126 dated June 15, 2026. The amendment followed CMDA’s request for greater authority under the Tamil Nadu Combined Development and Building Rules, 2019.

This revised system removes the need for a separate ministerial-level approval after CMDA scrutiny. 

Approval Numbers Show a Sharp Rise

CMDA approved 66 high-rise proposals in 2021, followed by 58 in 2022 and 30 in 2023. The number dropped to 17 in 2024 and just nine in 2025.

However, following the recent rule change, nearly 17 proposals were cleared within about a month. Several applications had reportedly remained pending for years under the earlier approval system.

CMDA Member Secretary Rahul Nadh said removing the government-level approval stage could save around two months in the processing of high-rise applications.

Developers Expect Faster Project Clearances

The real estate industry has welcomed the reform, as it removes one administrative layer and may help developers begin projects sooner. Faster planning approvals could also reduce financing costs and prevent prolonged project delays.

However, the change does not exempt developers from obtaining other mandatory permissions.

Developers must still obtain all applicable statutory permissions, which may include:

• Environmental clearance
• Airport Authority or aviation-related clearance
• Fire and rescue services clearance
• Traffic and infrastructure-related approvals
• Other permissions depending on the project’s height, size, location and use

Verified Real Estate assists developers in coordinating and obtaining these statutory approvals, helping them in ensuring a smoother and hassle-free project approval process.

What the Reform Means for Chennai Real Estate

The rapid clearance of 17 high-rise proposals suggests that the new system could improve the ease of doing business in Chennai’s construction sector. It may also encourage developers to take up larger residential, commercial and mixed-use projects across the metropolitan region.

The long-term impact will depend on whether CMDA can maintain faster approval timelines while ensuring that projects continue to comply with planning, safety, infrastructure and environmental regulations.

What Has Been Done So Far?

TThe preparation of the Third Master Plan commenced in December 2020. Since then, CMDA has:

• Conducted public consultations across Chennai and suburban areas.
• Held stakeholder meetings covering housing, transport, infrastructure, environment, economy, and technology.
• Undertaken more than 15 studies on land use, blue-green infrastructure, income patterns, gender-inclusive planning, temporal growth, and climate resilience.
• Prepared a vision document that forms the foundation of the master plan.

The plan also proposes major urban reforms such as transit-oriented development, vertical growth through higher FSI, mixed-use development, climate-resilient infrastructure, and the creation of new economic hubs.

Why Is an International Review Being Considered?

According to reports, the government intends to have the draft reviewed because certain aspects of the plan require further refinement to ensure practical implementation and alignment with global urban planning standards. International experts are expected to examine the plan’s proposals, identify any shortcomings, and provide recommendations that could help create a more robust and future-ready framework for Chennai’s growth.

If significant modifications are suggested, the government may revise portions of the draft before placing it in the public domain.

Chennai Metropolitan Area Expansion

One of the most significant developments during the preparation of the Third Master Plan was the expansion of the Chennai Metropolitan Area (CMA) in 2022. The planning area increased from approximately 1,189 sq km to about 5,904 sq km, bringing several additional urban and peri-urban regions under the metropolitan planning framework.

The integration of these newly added areas into the future planning framework is still under consideration, with separate regional plans expected to address the development needs of the expanded regions.

Why the Third Master Plan Matters for Real Estate

The Third Master Plan could have far-reaching implications for the real estate sector, particularly in:

• Metro corridors
• Transit-oriented development zones
• Mixed-use development areas
• Industrial clusters
• Commercial hubs and growth corridors

Potential impacts could include:

• Increase in land values.
• Higher development potential.
• Greater redevelopment opportunities.
• New infrastructure investments and economic activity.

However, since the draft has not yet been officially notified, landowners, developers, and investors should closely monitor these aspects and exercise caution before making any investment or project planning decisions until the final plan is released.

Grid of Roads Proposal: A Key Aspect to Watch

Another important aspect that stakeholders may need to closely monitor is the proposed Grid of Roads (GoR) network, which has already generated concerns within the real estate sector.

The proposal seeks to establish a planned road hierarchy and improve connectivity across the Chennai Metropolitan Area. However, developers and landowners have raised concerns that some proposed road alignments pass through approved layouts and private developments, potentially affecting project planning, land utilisation, and future approvals.

As the Grid of Roads proposal is expected to form part of the future planning framework, stakeholders may need to carefully examine whether their properties are impacted by any proposed road reservations before initiating development projects or making investment decisions.

How Could the Third Master Plan Impact Stakeholders?

Landowners

Properties located within future growth corridors, transit-oriented zones, and areas identified for higher development potential could witness appreciation in land values and increased redevelopment opportunities.

Developers and Builders

A well-defined master plan can provide planning certainty, unlock new development corridors, and create opportunities for high-density, mixed-use, and transit-oriented projects.

Commercial Property Owners

Commercial assets situated near transport nodes, economic hubs, and major infrastructure corridors could benefit from increased demand, improved connectivity, and higher rental and capital values.

What Could the Final Third Master Plan Include?

Based on the various studies undertaken by CMDA and the themes discussed in public consultations and previous reports, the Third Master Plan is expected to address areas such as land use, housing, transportation, economic development, environmental management, climate resilience, infrastructure planning, and implementation mechanisms. However, the final structure and contents of the plan will become clear only after the draft is officially released.

What Happens Next?

The next stages in the process are expected to include:

1. Review of the draft by international experts.
2. Release of the draft Third Master Plan.
3. Public comments and objections.
4. Any major recommendations could lead to revisions before the draft is released. 
5. Government approval.
6. Final notification before the existing Second Master Plan expires.

As Chennai prepares for its next phase of urban growth, the Third Master Plan could become one of the most influential policy documents for the city’s real estate, infrastructure, and economic development over the coming decades.

Below are four recent judicial milestones (2022 – 2025) that defined the enforcement of OSR norms in Tamil Nadu.

⚖️ 1. Association of Vasanth Apartments Owners v. CMDA & Ors.

Supreme Court of India | 13 Feb 2023 | C.A. Nos. 1890-91 of 2010 & 7847-48 of 2013

Background

Residents of a 12-block complex (> 10,000 m²) had already gifted their OSR land to CMDA in 1994. When the land was later used as a connecting road, the association claimed ownership and demanded that it be retained as a private park.

Core Issue

Can flat owners reclaim or control OSR land once it’s gifted to CMDA?
Is Rule 19 of the Development Control Rules (10 % OSR + gift deed) constitutional?

Court’s Reasoning

• Once gifted, title vests *irrevocably in the local authority; residents have no proprietary right.
• CMDA may use the land for any legitimate public purpose, including a road, provided the objective remains public welfare.
• Rule 19 is a valid regulatory restriction, not *expropriation.

Order / Holding

• Appeals dismissed; CMDA’s and Corporation’s actions upheld.
• OSR reservation and gift-deed mandate affirmed as *constitutional.

Excerpt:

“Reservation of ten percent area for communal and recreational purposes is not a taking but a reasonable regulatory measure… execution of a registered gift deed ensures the land is not exploited later for private purposes.”

⚖️ 2. Trellis South Flat Owners Welfare Association v. CMDA & Ors.

Madras High Court | Justice M. Dhandapani | W.P. No. 17008 of 2022 | 14 Oct 2022

Background

The petition related to the alienation of OSR land by the CMDA authorities in favour of the respondents, viz., Chennai Metro Rail Ltd. (CMRL), the land that was maintained by the Trellis South flat Owners Welfare Association, who is the petitioner . CMDA alienated this OSR land to CMRL for infrastructure works.
Similar use of OSR land at Shenoy Nagar Park had earlier prompted a Supreme Court undertaking that the park would be restored — an undertaking the agencies had failed to honour.

Core Issue

CMDA promised to restore the park and greenery after using OSR land for Metro construction, but didn’t do it — so the High Court stepped in again to enforce accountability and monitor restoration through a committee.

Court’s Reasoning

• The State must honour its word; development cannot come at the cost of nature.
• The Court is the “custodian of law,” duty-bound to enforce environmental undertakings.
• Status reports filed by CMRL were “*bereft of detail” and failed to show genuine restoration.

Order / Directions

• Constituted a five-member Restoration Committee (Amicus Curiae + CMDA + CMRL + Horticulture Dept + Local Residents) to monitor regreening.
• Ordered periodic reports and field inspections.

Excerpt:

“Development should be directly proportional to maintenance of the environment… any destruction to the environment under the guise of development spells doomsday for the nation.”

🌳 3. S.P. Thiyagarajan v. Commissioner, Tirunelveli City Municipal Corporation

Madras High Court | 12 Apr 2022

Background

The petitioner sought permission to convert land reserved as a park/playground into residential plots.

Core Issue

Whether land earmarked as OSR in an approved layout can later be converted for private use.

Court’s Reasoning

• OSR dedication creates a permanent public trust.
• Neither the promoter nor subsequent owners can alter or sell it.
• Allowing conversion would “defeat the very scheme of the layout.”

Order / Holding

• Conversion refused.
• Directed the Corporation to preserve the area as a park and take action against any encroachment.

Excerpt:

“The land earmarked as park and playground must remain so for public benefit and cannot be alienated by any individual.”

🚇 4. CMRL Skywalk / Sewer Works on OSR Land (Vadapalani)

Madras High Court | Aug 2025 | Reported Times of India

Background

Residents objected to Metro authorities using OSR land (already gifted to CMDA) for constructing a skywalk and underground sewer line near Vadapalani.

Core Issue

To create a seamless, fare-controlled connection between Vadapalani Metro Phase I and Phase II stations, which will allow passengers to transfer between lines without exiting the fare zone. To lay a new sewage pipeline as the existing one for the Phase I station was damaged by roadworks. To determine Whether this temporary use of OSR land for civic infrastructure violates its protected status.

Court’s Reasoning

• Public infrastructure of unavoidable necessity can coexist with OSR preservation if usage is temporary and reversible.
• CMDA remains custodian; land cannot be commercially exploited or permanently re-purposed.
• Ordered strict timeline and post-completion restoration.

Order / Holding

• Allowed construction subject to restoration of the open area.
• Directed transparency and community updates.

Excerpt:

“Public convenience, when temporary and reversible, can coexist with preservation of OSR land… such projects shall not change its character or title.”

🏞️ The Importance of OSR and the Legal Stand on Encroachments

Open Space Reservation (OSR) land is not just another vacant plot — it is a legally protected public asset meant to serve as the green lungs of urban neighbourhoods. These spaces preserve ecological balance, improve air quality, and provide recreation and mental relief in crowded cities.

Once a layout is approved with designated OSR areas, that land becomes untouchable for private or commercial use. Any construction, sale, or alteration of OSR land amounts to encroachment on community property and is treated as an illegal act under the Tamil Nadu Town and Country Planning Act.

Courts in Tamil Nadu have consistently ruled that no individual, association, or authority has the right to alter the purpose of OSR land, and violators can face demolition, restoration orders, and even contempt proceedings.

🦁Verified.Realestate’s Take:

Calculate mandatory 10% open space reservation requirements for layouts and developments in Tamil Nadu. Determine whether to reserve land or pay fee-in-lieu based on plot size, jurisdiction, and development type as per 2024 regulations.

*Irrevocably: Cannot be changed, taken back, or undone.

*Expropriation: When the government takes private property for public use, usually with compensation.

*Constitutional: Allowed or protected by the Constitution; legally valid under fundamental law.

*Bereft of detail: Lacking information or missing important specifics.

1. What is a Continuous Building Area (CBA)?

A Continuous Building Area (CBA) refers to urban zones or localities that feature densely clustered buildings with minimal open space between individual structures. In these areas, buildings typically share common walls or have minimal setbacks, creating a continuous stretch of built-up space.

CBA designation is essential for determining building regulations such as setback distances, permissible building heights, and Floor Space Index (FSI).

2. Importance of Continuous Building Areas in Urban Planning

Understanding CBA is crucial due to several factors:

• Urban Density Management:
  CBAs facilitate efficient utilization of limited urban land by optimizing available space.
• Infrastructure Planning:
  Urban planners use CBA designations to regulate infrastructure and service delivery, ensuring adequate utilities and accessibility.
• Legal and Regulatory Compliance:
  Properties within a CBA have specific building rules and regulations, including reduced setbacks and limited building heights.

3. Regulations for Continuous Building Areas in Tamil Nadu

In Tamil Nadu, including Chennai, building regulations for CBAs include:

• Minimal Setbacks:
  Properties within CBAs typically require minimal or no setbacks, allowing construction up to boundary lines, subject to specific local authority approval.
• Building Height Limits:
  Buildings within CBA are often restricted to Ground plus one floor (G+1), maintaining overall structural safety and fire regulations.
• Permissible Construction:
  CBA areas generally permit residential and small commercial establishments but may restrict high-rise or expansive constructions.
• Road Width Consideration:
  In Chennai and other Tamil Nadu cities, CBA rules often stipulate specific minimum road widths to facilitate access and emergency services.

4. Importance of Verifying Your Property’s CBA Status

Accurate verification of your property’s CBA status ensures:

• Compliance with Building Regulations:
  Avoid legal disputes, penalties, and project delays by adhering strictly to CBA construction rules.

   • Patta/TSLR/Chitta: Up-to-date land records in your name.
   • Layout Plans or FMB Sketch: Any available approved layout or field measurement book record.
   • Encumbrance Certificate (EC): Verifies the property is free from legal liabilities.
   • Tax Receipts: Proof of regular property tax payments.
3. Application Submission:
   • File an application with the local authority or municipality. Many regions now offer online portals for submission.
   • Ensure the application is complete and includes all supporting documents.
4. Fee Payment:
   • Pay the required fee as per the consolidated fee structure. Fees are generally based on the plot area and may vary across municipalities.
5. Inspection and Verification:
   • Authorities conduct a site inspection to verify the information provided and assess compliance with local planning norms.
   • Additional clarifications or documentation may be requested if discrepancies are found.
6. Issuance of Regularisation Order:
   • Once all criteria are met, the local authority issues a regularisation order or certificate, legally converting your unapproved plot into an approved property.

4. Benefits of Regularisation

• Legal Security:
  Regularisation provides official recognition, reducing risks of legal disputes.
• Increased Property Value:
  Legally approved properties have higher resale and financing potential.
• Improved Infrastructure:
  Regularised plots become part of official urban planning, benefiting from planned infrastructure and amenities.
• Reduced Transaction Risks:
  Clarity in property status simplifies future sales, inheritance, and loan applications.

5. Challenges and Considerations

Delimitation is a cornerstone of effective urban governance. By redrawing ward or constituency boundaries, the Greater Chennai Corporation (GCC) aims to adapt to population shifts and evolving development patterns. As one of India’s oldest municipal bodies, the GCC oversees a range of civic amenities, from waste management to community welfare. Its 200 wards are grouped into various zones—previously 15, now heading toward 20 in some proposals—ensuring localized governance for one of India’s most vibrant metropolises.

1. Why Delimitation Matters

• Equitable Service Delivery: As neighborhoods grow or transform, delimitation aligns ward boundaries with demographic realities, ensuring equitable access to municipal services (e.g., water supply, road maintenance).
• Administrative Manageability: Each ward targets a specific population range, making it easier for civic officials to plan, monitor, and improve local infrastructure.
• Inclusive Representation: Balanced ward sizes mean each area’s voice is heard proportionally, preventing over- or under-representation in local governance.

2. Understanding the Draft Proposal

The “DELIMITATION OF WARDS DRAFT PROPOSAL” document is a blueprint detailing ward sizes, populations, housing data, and boundary outlines. Key metrics include:

• 2011 Census Population: Baseline figures for each proposed ward.
• Sanctioned Strength (Wards per Zone): The total approved wards, guiding average population targets.
• Residential Buildings & Households: Captured from Census 2011, offering a glimpse of each ward’s density and housing patterns.
• Boundaries: Natural or administrative delimiters like rivers (Adyar, Cooum, Kosasthalaiyar), highways, railway lines, industrial sites, and historical village limits.

3. Major Observations by Zone

• Zone 1 (Thiruvottiyur & Environs):
  • Wards aim for ~20,000 population each.
  • Coastal wards near Kathivakkam and Thiruvottiyur align boundaries along the Bay of Bengal and Buckingham Canal.
  • Some exceed targets by over 10% due to dense urban pockets or industrial adjacency.
• Zone 2 (Manali & Surroundings):
  • Average population set at ~15,000.
  • Natural barriers like the Kosasthalaiyar River prevent merging smaller wards, resulting in stark under-population (e.g., Ward 17 with ~5,000).
  • Others shoot above 25,000 due to gated communities or dense slum tenements.
• Zone 3 (Madhavaram & Puzhal):
  • Also centered around ~15,000.
  • Key roadways (GNT Road, 200 Feet Road) and “village boundaries” often dictate ward limits.
  • Industrial or commercial pockets elevate population figures in select wards.

From Zone 4 onward, each region references large infrastructure (e.g., CPCL refineries, defense cantonments) and major roads (Anna Salai, E.V.R. Periyar Salai, etc.) as ward boundaries. The presence of Tamil Nadu Slum Clearance Board (TNSCB) colonies often causes certain wards to surpass average populations by as much as 40%.

4. Reasons for Population Variances

• Natural Boundaries: Rivers, canals, or lakes (like Periyathopu Lake) can isolate neighborhoods, making merging impractical and creating wards with populations well below average.
• Industrial Zones: Large industrial complexes occupy land without significant residential presence, resulting in wards with fewer residents.
• TNSCB Colonies: Slum tenements concentrate thousands of residents in compact areas, pushing population counts far above the median.
• Administrative Constraints: Village boundaries, historical divisions, or lack of bridging infrastructure (e.g., no direct road over a river) can lock in lower or higher populations than targeted.

5. Stakeholder Implications

• Residents:
  • Enhanced Service Delivery: More balanced populations foster efficient garbage collection, road maintenance, and public health initiatives.
  • Local Identification: Knowing your exact ward number ensures accurate access to schemes and quick redressal of civic complaints.
• Urban Planners & Policymakers:
  • Resource Allocation: The draft’s data highlights where to build new roads, schools, or healthcare centers.
  • Long-Term Urban Planning: High-density wards (often with slum clusters) necessitate unique development strategies.
• Real Estate & Business:
  • Investment Insights: Dense or newly annexed wards could see rises in property values as infrastructure improves.
  • Boundary Verification: If your property sits near a newly carved ward limit, tools like the Survey Number Finder can help confirm exact boundaries.
• Academics & Researchers:
  • Data Access: Comprehensive metrics—population, building counts, household patterns—fuel robust studies on urbanization and demographic changes.

6. Future Outlook

As Chennai’s population and economy evolve, periodic recalibrations of ward boundaries are inevitable. This draft—based on 2011 Census figures—will likely undergo multiple rounds of review to incorporate stakeholder feedback. Over time, the government may factor in new census data and infrastructural developments (e.g., expanded Metro lines, proposed ring roads), leading to further realignment.

Conclusion

The Delimitation of Wards Draft Proposal offers an essential glimpse into Chennai’s civic structure. By balancing population loads, respecting natural and industrial constraints, and staying transparent about variations, the GCC aims to craft wards that are both administratively feasible and equitable for residents. Whether you’re a policymaker, investor, or simply an engaged citizen, understanding these ward boundaries helps you anticipate how Chennai’s infrastructure and community services will grow in the coming years—ensuring the city remains an inclusive, dynamic hub in Tamil Nadu’s urban landscape.

North Chennai Set for a Major Infrastructure Overhaul

The Greater Chennai Corporation (GCC) has embarked on a significant transformation initiative under the North Chennai Development Plan. A total of 36 projects, with an estimated budget of ₹150 crore, have been approved to enhance public amenities and infrastructure. The move aims to rejuvenate the historically rich but underdeveloped regions of North Chennai, spanning areas from Tiruvottiyur to Thiru Vi Ka Nagar.

The North Chennai Development Plan is a joint effort between GCC and CMDA, with funding contributions of ₹150 crore from CMDA and an additional ₹7.58 crore from the Chennai Corporation. The Municipal Administration and Water Supply Department granted approval in October 2024, and implementation is now in full swing.

Key Projects and Infrastructure Upgrades

Among the planned projects, notable developments include:

• Madhavaram Bus Terminus Expansion: Expected to improve public transport connectivity in the region, benefiting daily commuters, especially women and students.
• Eco Park at Sanal Street, Tondiarpet: A modern, green recreational space set to be completed before the northeast monsoon.
• Upgradation of Smoke-Free LPG Crematoria: Enhancing funeral facilities in Tondiarpet for an eco-friendly approach to last rites.
• Flood Mitigation Measures: Implementation at 13 locations in Tondiarpet and 10 in Royapuram.
• Modern Gymnasium on Wall Tax Road: Promoting health and fitness infrastructure.
• Library and Public Health Centers: Improving educational and healthcare access for residents.

Government’s Vision for North Chennai

Chief Minister M.K. Stalin has accelerated project execution under the Vada Chennai Valarchi Thittam (VCVT), ensuring timely completion. Chennai Metropolitan Development Authority (CMDA) Minister P.K. Sekarbabu confirmed that 80% of projects are targeted for completion by December 2025.

Major Civic and Social Projects

Apart from transport and green spaces, the plan also includes:

• Housing Projects: 776 tenements (stilt + 9 floors) on Stanley Medical College Road at ₹160 crore.
• Water Supply Enhancement: Kannikapuram drinking water project at ₹59.15 crore.
• Slaughterhouse Construction: Perambur Barracks Road project.
• School and Maternity Hospital Upgrades: Chennai Schools and United India Colony Maternity Hospital, with a ₹9 crore budget.

A New Era for North Chennai

With focused efforts on improving transportation, public health, education, and green spaces, North Chennai is on the path to becoming a more sustainable and well-connected region. The GCC’s ambitious plan is set to redefine urban living standards for residents, reinforcing the area’s historic significance while addressing modern civic needs.

Urban planning is a vital aspect of infrastructure and city development, which directly impacts the quality of life in a region. This article examines the differences in approval authorities and urban planning between Tamil Nadu and Karnataka, highlighting the key factors that have led to their contrasting development paths. While Karnataka boasts a comprehensive master plan with localized approval authorities, Tamil Nadu lags behind with a centralized system that impacts the efficiency and speed of urban growth.

1. State of Urban Infrastructure Until the 1980s

In the 1980s, Bengaluru was considerably behind Chennai in terms of infrastructure. Roads, flyovers, and drainage systems in Bengaluru were underdeveloped compared to Chennai. However, the tides have turned dramatically since then.

2. Rapid Growth of Bengaluru

From the 1980s to 2010, Bengaluru experienced unprecedented growth in infrastructure and urban development. The city quickly evolved into a global hub, surpassing Chennai and attracting multinational corporations due to its well-planned urban landscape.

3. Karnataka’s Master Plan

Karnataka’s success can be attributed to its well-structured master plan, which zones areas for agriculture (green zones) and residential purposes (yellow zones). This structured planning, carried out by various specialized authorities, has been critical in managing Bengaluru’s rapid growth and maintaining organized urban development.

4. Global Companies in Bengaluru

The pre-planned infrastructure made Bengaluru an attractive destination for global companies, facilitating its transformation into an international hub. The city’s organized planning helped in the smooth establishment of IT parks and corporate offices.

5. Tamil Nadu’s Planning Authorities

Tamil Nadu operates with two major approval bodies:

• CMDA (Chennai Metropolitan Development Authority): Governs Chennai and surrounding areas.
• DTCP (Directorate of Town and Country Planning): Handles other cities and rural regions of Tamil Nadu.

6. Lack of a State-Wide Comprehensive Master Plan in Tamil Nadu

Unlike Karnataka, Tamil Nadu lacks a cohesive master plan for the entire state. While cities like Chennai have localized master plans, much of rural Tamil Nadu remains unplanned, stifling growth in smaller towns.

7. Master Plan for Major Cities in Tamil Nadu

Cities like Coimbatore, Madurai, and Trichy have their own Local Planning Authorities (LPA) that handle city-specific master plans. However, smaller towns and rural areas remain unaddressed by comprehensive planning strategies.

8. Centralized DTCP Office in Tamil Nadu

One of the major challenges in Tamil Nadu is the centralization of the DTCP office in Chennai, which handles approval processes for all non-Chennai areas. This has raised concerns over delays and inefficiencies in approving projects, especially for cities far from Chennai.

9. Uniform DTCP Regulations Across Tamil Nadu

Another challenge is the uniformity of regulations enforced by DTCP across the state, which fails to account for local differences in land value, population density, and geography. For example, Coimbatore and Tirunelveli have vastly different land values, yet they are governed by the same approval standards, limiting flexibility for development.

10. Recent Revisions in Plot Sizes

In response to growing demand for affordable housing, DTCP has recently allowed up to 10% of plots in new layouts to be as small as 600 sq. ft., aimed at helping economically weaker sections (EWS). However, many feel that this change doesn’t adequately address the actual needs of middle- and lower-income groups.

11. Karnataka’s Tailored Planning Authorities

Karnataka has a more localized system of planning authorities:

• BDA (Bangalore Development Authority) for core Bengaluru.
• BMRDA (Bangalore Metropolitan Region Development Authority) for suburban and outer areas.
• MUDA (Mysore Urban Development Authority) for Mysore, along with other local bodies for smaller cities like Chikmagalur.

Each of these authorities has a clear mandate to manage their specific region, allowing for more efficient and tailored urban development.

12. Master Planning for Rural Karnataka

Even rural areas in Karnataka benefit from a comprehensive master plan, which ensures controlled development by designating zones for agriculture and residential use. The process of converting agricultural land into residential zones, known as DC Conversion, adds a layer of transparency and control that is missing in Tamil Nadu.

13. Comparing Tamil Nadu and Karnataka

The centralized planning approach in Tamil Nadu contrasts sharply with Karnataka’s localized and customized planning bodies. While Tamil Nadu’s DTCP enforces blanket regulations across the state, Karnataka’s region-specific planning bodies ensure urban growth that is suited to local needs and conditions.

Conclusion

The comparison between Tamil Nadu and Karnataka reveals stark differences in their approach to urban planning and approval authorities. Karnataka’s focus on a comprehensive, localized planning system has allowed it to leap ahead in terms of infrastructure development, while Tamil Nadu’s centralized, one-size-fits-all approach has led to inefficiencies and delays. For Tamil Nadu to catch up, it must adopt more flexible and region-specific planning mechanisms, as seen in Karnataka.
