Under TNCDBR 2019 – Rule 28, the law is simple:

👉 No structure should be constructed within the mandatory setback spaces
unless specifically permitted in the regulations.

Setbacks (front, side, and rear) are meant to ensure:

• Ventilation
• Fire safety
• Access for emergency vehicles
• Light and open space

So by default, you cannot build anything in setback areas —
but there are limited exceptions.

✅ What Is Allowed in Setback Areas?

Certain minor and utility structures are permitted, but only within strict limits:

1. Sunshades

• Projection allowed: Up to 0.6 meters
• Should not obstruct movement or neighboring space

2. Motor Room

• Maximum area: 2 sq.m
• Maximum height: 1.8 meters
• Must not affect parking or driveway access

3. Open Staircase

• Allowed only for buildings up to 9 meters height
• Must maintain required boundary clearances

4. Compound Wall

• Maximum height: 2.0 meters

5. Watchman Booth

• Maximum size: 2.5 m × 2.5 m
• Maximum height: 3 meters

6. Gate Pillars / Entrance Arches

• Minimum headroom: 5.5 meters
• Minimum width clearance: 3.5 meters

7. Electrical & Utility Installations

Includes:

• Meter rooms
• Electrical panels
• Open transformers

Conditions:

• Must be within 0.6 m projection
• Must comply with safety norms

⚠️ What Is NOT Allowed?

Anything beyond the above list is illegal in setback areas, including:

• Room extensions
• Kitchens or bathrooms
• Covered garages (unless separately approved)
• Commercial usage structures

👉 Even small violations can lead to:

• Plan rejection
• Penalties
• Demolition notices

🧠 Practical Insight (What Most People Get Wrong)

Many property owners assume:

“It’s my land, I can build anything inside my compound.”

That’s wrong.

👉 Setback space is regulated, not free-use land.

Even temporary or small constructions can become legal risks during resale, bank loans, or approvals.

Before buying or constructing:

• ✅ Setback compliance verification
• ✅ Building plan approval checks (CMDA / DTCP)
• ✅ On-ground inspection to detect violations
• ✅ Legal risk assessment before purchase

👉 This ensures the property is safe to buy, sell, and finance

🏁 Final Takeaway

Rule 28 is strict for a reason.

✔ Only specific minor structures are allowed
❌ Anything else in setback = violation

👉 If you ignore this, it will show up later during:

• Registration
• Bank loan processing
• Legal disputes
