Forty per cent of homeless people accessing services last year were looking for help for the first time.
More than 4,600 people living on the streets of Dublin asked for assistance in 2013.
The number of people using homeless services in the capital last year was 4613, and of those 1958 were newly homeless.
The number of families put up in hotels because no other accommodation was available was described as reaching "chronic proportions".
The new figures were released by the Dublin Region Homeless Executive.
Some 130 families are currently living in hotels but rising rents and a lack of housing in Dublin means this figure could increase, the organisation said.
Last year 793 people moved out of homelessness into rented accommodation, while the figure was just 879 in 2012.
The executive assists homeless people with linking with their local authority to ensure they have temporary accommodation.
In 2012, some 1,451 people were living in emergency accommodation each night.
The majority of homeless people are men at 75 per cent, while women constitute 25 per cent of those sleeping rough on the street according to last year’s figures.
