No casualties have been reported.
The BSEC has formed a five-member committee to look into the incident.
Fire service control room said the 10-storey building caught fire just before Friday noon.
Fifteen fire-fighting units doused the flames after over two hours of frantic efforts, Fire Service and Civil Defence Director General Ali Ahmed Khan said.
Television footage showed smoke belching out of the building's top floor and fire-fighters trying hard to tame the flames.
On Feb 26, 2007, three people were killed and 10 offices, including those of the Ntv, Rtv and Amar Desh, destroyed in a fire in the same building.
The building houses about 30 organisations now.
What caused the blaze is not clear, although firemen suspect it originated from a storehouse on the top floor.
'Bablu', an employee of a law farm on the 10th floor, said they had heard a noise that sounded like an electric short-circuit.
"Our security guard requested us to vacate the building seeing fumes," he said.
bdnews24.com photojournalist Asif Mahmud Ove had earlier said the scene was chaotic.
"Fume is gushing out of the building and firemen are spraying water and foam to douse the blaze," he said.
Fireman Abul Hossain said he had tried to use a stair on the north side of the building but could not due to thick smoke.
Most of the organisations are shut on weekend but media persons were at their offices. They got out soon after the fire spread.
Rtv offices are located on the fifth floor. Its News Editor Akter Hossain said Ntv and Amar Desh offices are located on the sixth and top floor respectively.
Ntv has two tin-shed transmission rooms on the roof.
Chief news editors Ntv and Rtv -- Zahirul Alam and Anowar Haq -- said their channels temporarily went off the air after the power connections were cut following the fire.
Amar Desh's Mahmuda Doli said her newspaper's online edition was running.
"We were supposed to work at Niketan this morning. That's why our newsroom was empty.
"The incident (fire) seems mysterious," she told bdnews24.com Senior Correspondent Liton Haider.
Ntv Chairman and Managing Director Mosaddak Ali Falu who rushed to the scene said he suffered losses each time the building caught fire.
"They (fire incidents) are investigated but no report is ever filed," he alleged.
"It's necessary to know why fire is recurrent in this building."
Rtv's Special Correspondent Shameema Akter said they had learnt that the fire originated from a warehouse of Amar Desh on the top floor.
"The fire was first spotted at the storage," she said. "All of us got down safely."
Amar Desh's Office Assistant Abbas Ali Hawlader said they were busy shifting their offices.
"A spark was seen at the store room but it was locked," he said.
The man who had the keys was called and they tried to put out the fire themselves. Fire service was called afterwards, leading to the evacuation from the building.
"All of us on the top floor got out. I don't think anyone was trapped," he said.
Around 1:30pm, Fire Service Director Mohammad Mahbub said they had brought the fire under control.
"The store room had a large amount of papers. That's why it took us so long," he said.
Fire Service DG Khan said he had visited the top floor and did not find anyone trapped or saw any casualties.
Industries Minister Amir Hossain Amu went there before the fire was put out.
When asked about the report of the 2007 fire probe committee, he said he would look into it.
Meanwhile, a five-member committee, headed by BSEC Bhaban Director Syed Mozammel Haq, has been formed, said BSEC Chairman Mohammad Imtiaz.
It has been ordered to submit its findings within 10 days.
