"We are acting immediately. The checking of all the buildings will start from morning itself," fire and emergency services director Ashok Menon said.
He said the chief secretary spoke to him in the morning before issuing the advisory.
The main concentration would be on buildings like the secretariat, ministerial block and state Legislative Assembly complex, which are power centres and visited by thousands of people daily.
In addition, buildings like Junta house located in the city and Shramashakti Bhavan located at the outskirts, which houses the offices of government departments will also be checked.
Menon said the Public Works department (PWD), which maintains the buildings, had asked to amend certain fire safety arrangements at state Legislative Assembly complex.
"We are yet to receive back any communication from them. But we will be inspecting the Assembly complex building today as the session would be in progess from July 12 onwards," the director said.
The fire and emergency departments will also conduct mock drills at the secretariat and other buildings during peak hours to educate people on evacuation, in case of any calamity.
The fire in the Mantralaya building in Mumbai left 3 dead and 16 others injured.
