<p class="wp-block-paragraph">The Chennai Metropolitan Development Authority has strict regulations governing compound walls, road widening reservations, and Open Space Reservation (OSR) land in residential and commercial developments.</p>



<p class="wp-block-paragraph">Builders must ensure that approved infrastructure corridors and public-use spaces remain free from permanent encroachments.</p>



<hr class="wp-block-separator has-alpha-channel-opacity"/>



<h3 class="wp-block-heading">Compound Wall Restrictions in Road Widening Areas</h3>



<p class="wp-block-paragraph">Permanent compound walls are not permitted within:</p>



<ul class="wp-block-list">
<li>Approved street alignment zones</li>



<li><a href="https://verified.realestate/dashboard/utility/proposed-road-widening-check" target="_blank" rel="noreferrer noopener">Proposed road widening areas</a></li>



<li>Future infrastructure reservation corridors</li>
</ul>



<p class="wp-block-paragraph">Builders are required to leave the designated widening extent unobstructed as per the sanctioned layout plan.</p>



<p class="wp-block-paragraph">Temporary provisions such as:</p>



<ul class="wp-block-list">
<li>Landscaping</li>



<li>Grill fencing</li>



<li>Barbed wire fencing</li>



<li>Dwarf walls below 0.60 metres</li>
</ul>



<p class="wp-block-paragraph">may be permitted because they can be removed during future road expansion works.</p>



<hr class="wp-block-separator has-alpha-channel-opacity"/>



<h3 class="wp-block-heading">Open Space Reservation (OSR) Compliance</h3>



<p class="wp-block-paragraph">OSR land is reserved for:</p>



<ul class="wp-block-list">
<li>Public open spaces</li>



<li>Parks</li>



<li>Community welfare</li>



<li>Environmental balance</li>
</ul>



<p class="wp-block-paragraph">Once vested with the competent authority or local body:</p>



<ul class="wp-block-list">
<li>No permanent structures may be constructed</li>



<li>Private occupation is prohibited</li>



<li>Commercial usage is not permitted without approval</li>
</ul>



<p class="wp-block-paragraph">Builders must preserve OSR land strictly according to sanctioned planning conditions.</p>



<hr class="wp-block-separator has-alpha-channel-opacity"/>



<h3 class="wp-block-heading">Why These Regulations Are Important</h3>



<p class="wp-block-paragraph">These provisions help:</p>



<ul class="wp-block-list">
<li>Enable future road expansion</li>



<li>Reduce urban congestion</li>



<li>Preserve green and recreational spaces</li>



<li>Support sustainable city planning</li>



<li>Improve public infrastructure development</li>
</ul>



<p class="wp-block-paragraph">Unauthorized encroachments may lead to:</p>



<ul class="wp-block-list">
<li>Demolition notices</li>



<li>Planning violations</li>



<li>Approval cancellation risks</li>



<li>Legal disputes with authorities</li>
