The number of new homes will need to increase by 8 per cent per year to meet the Housing for All targets by 2030.
The Society of Chartered Surveyors says 27,000 new homes need to be built this year.
An annual property review from the SCSI is warning rising construction costs may negatively impact housing completions this year and next.
Agents have expressed concern that commencements and planning permission numbers are declining and this will affect the number of completions.
Dr Rory Hearne, assistant professor in social policy at Maynooth University, says the "Housing For All" targets are too low.
Meanwhile, a Simon Communities report shows just 41 properties were available to rent across the country last month, for people reliant on the Housing Assistant Payment.
Of these properties, 40 fell within discretionary HAP limits and only one property was available to rent under a standard HAP rate.
Ben Thompson from Churches Estate Agent says the number of landlords accepting HAP has improved.
The report comes amid record levels of homelessness, with 11,542 people in emergency accommodation according to latest monthly data.
