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.
Builders must ensure that approved infrastructure corridors and public-use spaces remain free from permanent encroachments.
Compound Wall Restrictions in Road Widening Areas
Permanent compound walls are not permitted within:
- Approved street alignment zones
- Proposed road widening areas
- Future infrastructure reservation corridors
Builders are required to leave the designated widening extent unobstructed as per the sanctioned layout plan.
Temporary provisions such as:
- Landscaping
- Grill fencing
- Barbed wire fencing
- Dwarf walls below 0.60 metres
may be permitted because they can be removed during future road expansion works.
Open Space Reservation (OSR) Compliance
OSR land is reserved for:
- Public open spaces
- Parks
- Community welfare
- Environmental balance
Once vested with the competent authority or local body:
- No permanent structures may be constructed
- Private occupation is prohibited
- Commercial usage is not permitted without approval
Builders must preserve OSR land strictly according to sanctioned planning conditions.
Why These Regulations Are Important
These provisions help:
- Enable future road expansion
- Reduce urban congestion
- Preserve green and recreational spaces
- Support sustainable city planning
- Improve public infrastructure development
Unauthorized encroachments may lead to:
- Demolition notices
- Planning violations
- Approval cancellation risks
- Legal disputes with authorities
