How Many Illegal Buildings in Islamabad Have Been Identified?
According to a written reply submitted to the National Assembly, 439 buildings in Islamabad are illegal, as they were constructed without approved building plans or any official permission. ProPakistani
This is not a small number. These are structures spread across some of the most sought-after zones of the capital, and their illegal status puts buyers, tenants, and investors at serious financial and legal risk.
Where Are These Illegal Buildings Located?
These structures are mostly located in Zone 1 and Zone 2 and do not comply with the rules and regulations of the Capital Development Authority. ProPakistani
Zone 1 and Zone 2 are among the most premium and high-demand areas in Islamabad. The fact that illegal buildings in Islamabad are concentrated in these zones means that even high-value property buyers are exposed to risk if they do not verify documents before purchasing.
What Action Has the CDA Taken?
The Capital Development Authority has not stayed silent on the matter. Here is a breakdown of the actions taken so far:
Notices Issued: Show cause notices have been served to all 439 illegal buildings in Islamabad for violating building laws.
Fines Collected: The CDA has so far collected Rs. 931,273,360 in fines from these illegal constructions. ProPakistani That is over 93 crore rupees in penalties, which reflects just how widespread the problem is.
Buildings Sealed: 152 buildings have already been sealed over violations of the relevant rules. ProPakistani Sealing means these properties cannot be used, rented, or sold until violations are resolved.
On the instructions of Chairman CDA Muhammad Ali Randhawa, the enforcement of building bylaws across the entire city is being ensured, and operations against building bylaw violations will continue consistently. CDA Gallery

Why Do Illegal Buildings in Islamabad Exist?
The core reason illegal buildings in Islamabad exist is a lack of verification by buyers and a failure by some developers to obtain proper approvals before construction. Common violations include:
- Construction without an approved building plan from the CDA
- Buildings used for purposes different from what was approved
- Structures built in violation of CDA zoning regulations
- No NOC obtained before starting construction
According to CDA bylaws, a housing project is considered illegal if it does not have an approved Layout Plan, has not obtained a valid NOC, or is built on land reserved for Green Belts, Parks, or Government institutions. Pin92
What Are the Risks for Buyers and Investors?
Buying or investing in illegal buildings in Islamabad can lead to serious consequences:
- Your property can be sealed at any time by the CDA
- You can lose your entire investment with no legal recourse
- The building can be demolished without compensation
- You may face legal action as an occupant or owner
