Cork Simon Community says the increased demands have had a significant impact on their operations.
The charity ended 2022 with a 750 thousand euro deficit after raising over 5 point 4 million euro.
Its annual Impact Report describes last year as one of it's most "challenging" years ever, with a 33 per cent increase in people seeking help.
Speaking to RedFM News, Paul Sheehan from Cork Simon expects homeless charities across the country will experience even greater demand this year
"We're actually faring a little bit better here in Cork than nationally, and might be a little bit above the average in terms of people being housed. Single households in particular will be depending on the private rental sector they're pretty much locked out of that and rent just keeps increasing. The amount of people in their late 20s and early 30s who are still living at home - these are all signs of huge pressure still to come on the housing system, and ultimately on homelessness services"
