Minimum Road Width & Plot Size Rules for DTCP in Krishnagiri
Urban and rural development in Tamil Nadu is governed by the Town & Country Planning (T&CP) Act, 1971 and the Tamil Nadu Combined Development and Building Rules, 2019 (“TN CDBR 2019”). These regulations ensure planned growth, adequate infrastructure, and sustainable land use across towns and districts — including Krishnagiri. If you plan to develop land or buy a plot in this region, understanding minimum road width requirements and plot size rules under DTCP regulations is critical, especially for securing DTCP Approval in Krishnagiri.
What is DTCP Approval and Why It Matters
DTCP Approval refers to the sanction provided by the Directorate of Town & Country Planning (DTCP) — the authority empowered under the T&CP Act to regulate planning permissions, layout approvals, and sub-divisions in areas outside the Chennai Metropolitan Development Authority (CMDA). In Krishnagiri, the Local Planning Authority (LPA) operates under DTCP, implementing the master plan and development control rules.
A DTCP approval is essential because:
It validates the layout plan in compliance with master planning and zoning norms.
It enables legal subdivision/sale of plots and future construction permissions.
Banks and financial institutions often require DTCP-approved land for property loans. (Common community reports underscore this point from land-buyer discussions. )
Without DTCP approval, layouts may be considered unapproved, delaying registrations and impacting resale value.
Minimum Road Width Requirements Under DTCP (Tamil Nadu Rules)
In the Tamil Nadu Combined Development & Building Rules, 2019, detailed standards are set for internal roads and passages in new layouts or subdivisions. These standards apply across districts — including Krishnagiri — unless superseded by local master plans.
1. Road Width in Residential Layouts
According to Section 47 of the rules:
Internal streets and roads within residential layouts must adhere to the following minimum widths:
Streets up to 120 m long: 7.2 m
Streets between 120 m and 240 m: 10 m
Roads 240 m to 400 m: 12 m
Roads 400 m to 1000 m: 18 m
Roads over 1000 m: 24 m
These widths ensure comfortable vehicular movement, adequate space for utilities, drainage, and future expansion.
Smaller passages serving only a few plots may have reduced widths, for instance:
Up to 2 plots: 1–1.5 m (private passage)
Up to 10 plots: 4.8 m (private)
However, these passages often remain private unless formally taken over by the local body under DTCP approval.
2. Road Width When Connected to Major Roads
For subdivisions touching National or State Highways, developers must provide a service road of at least 7 m width including a median, even if the main road is wider.
This condition protects highway safety and ensures clear access to plots.
3. Wider Roads for Extension
Additionally, in layouts where roads can be extended to adjacent lands (future expansion), the minimum internal road width should be 9 m. This provision supports long-term connectivity, preventing layouts from becoming isolated pockets.
Minimum Plot Size & Frontage Rules
While the CDBR 2019 primarily focuses on internal roads, plots in approved layouts must also satisfy certain size and frontage norms — especially for planning permission:
1. Base Plot Size Requirements
Under the general building rules (as referenced in the planning authority FAQ for Tamil Nadu):
Residential plots: Minimum 220 sq. m
Commercial plots: Minimum 300 sq. m
Institutional plots: Minimum 892 sq. m
Industrial plots: Minimum 892 sq. m
Minimum frontage for residential plots is 9 m (same as road width).
These requirements ensure adequate space for construction, setbacks, and access roads — and they apply when seeking building plan approvals in DTCP jurisdiction.
Another note from the 2019 rules:
Within a DTCP-approved layout, Economically Weaker Section (EWS) plots can have a minimum area of 32 sq. m, while other category plots should be at least 72 sq. m.
Why Road Width & Plot Size Rules Matter for DTCP Approval in Krishnagiri
Legal Compliance
Layouts that do not meet these minimum standards for roads and plots risk being rejected during DTCP scrutiny. Roads that are too narrow or plots without proper frontage are common reasons for delay.
Connectivity and Civic Infrastructure
Proper road widths allow emergency vehicles, garbage trucks, and public transport to access sites. They also influence drainage planning and utility routing.
Resale and Financial Value
Plots in DTCP-approved layouts with compliant road widths and plot sizes enjoy better market confidence and ease of financing.
Final Thoughts
If you’re planning to develop or buy land in Krishnagiri, securing DTCP Approval in Krishnagiri is a smart and often necessary step. Meeting minimum road width requirements and plot size rules isn’t just bureaucratic formality — it ensures long-term legal compliance, better infrastructure, and higher property value.
Always consult the latest DTCP guidelines and master plan applicable for Krishnagiri Local Planning Area before investing or submitting your layout plan. And consider professionals (licensed planners, surveyors, or architects) to help navigate technical requirements.
