In case of non-compp,liance, buildings face demolition. z Local gg(government officers (Registered Architects and Engineers) are responsible for implementation. Issues of implementation z Illegal construction carried out without permit. z Failure of local governments to supervise construction, especially outside cities. z Ignorance of the latest building code by professionals. z Ratio of illegal buildings is high (approx. 70% in total building stock). 60% of buildings are non- engineered, 30% of which is built by the owners. Many houses are built on sand and other disaster prone soft soil.

Preventing new construction of illegal buildings is essential. Building Permit Process needs to be implemented urgently and effectively. 2. Educati on on h ousi ng saf et y for the public and technicians is essential. 3. Policy to address existing vulnerable houses is needed. Dhanya Baad! Thank you for your attention..
