"There was wooden panelling in the corridor because of which people couldn't use corridors to evacuate", fire officer Vipin Kental said. It was extinguished after a three-hour operation, with 35 people rescued.
He says authorities are still investigating what caused the fire.
"So I have also directed the fire department to inspect such multi-storeyed buildings which have five floors or more and submit a report in a week's time", he said.
The dead included a woman and a child who had tried to escape by jumping from a fifth-floor window of the 65-room hotel in the shopping district of Karol Bagh, some of which had been booked by a wedding party.
More than two dozen fire engines were sent to the spot after the fire broke out on the top two floors of Hotel Arpit Palace around 4 am.

Juventus said that the club are liable to pay 3.7 million euros ($4.1 million) by July 10 in the absence of a transfer fee. Ramsey , 28, issued his own statement via Instagram.
Meanwhile, the vice-president of the Delhi Hotel Association Balan Mani told ANI that all fire norms were maintained in the hotel.
"It was due to a fire in ducting because of which it spread to the hotel rooms".
"A licence is issued only after inspection". "Mishappening can occur in a house as well", he added.
Authorities in Delhi have frequently launched raids to enforce building codes, fire safety measures and evacuation procedures but these steps have failed to check rampant violations by builders in a rapidly expanding capital city of more than 18 million people.
Prime Minister Narendra Modi also expressed grief on the incident and offered condolences to the family of those killed.
