📌 What Does Rule 28 Say?
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
