Cork county lies sixth in terms of overall demand for housing in the country - despite this, the number of homes sold last year rose just 26pc across the city and county, with 4,063 homes trading hands.
The Housing Agency examined demand in 29 urban areas in the county - it found there was none in nine areas. In nine others, there was a need for 100 or more units including Carrigaline (535), Midleton (372), Cobh (352) and Carrigtwohill (330).
A new town is planned at Monard, close to the city, to cater for future growth.

Other towns earmarked for future expansion including Ballicollig, Blarney, Carrigaline, Carrigtwohill, Cobh, Glanmire, Passage West and Midleton.
But problems may arise in meeting demand in some locations. There is no land zoned for primarily for housing in Rathcormac. This is despite the Housing Agency saying the population is projected to rise by almost 20pc to 1,819 by the end of 2018, with 106 new homes needed.
A similar problem exists in Watergrasshill, south of Rathcormac, where the population is expected to increase from 1,161 at present to 1,448, up 24pc. There is a need for 97 units, according to the agency.
Land zoned (ha): 1,476
Potential number of homes: 25,995
Housing requirement: 2,749
Percentage of zoned land needed: 10.5pc

The Residential Land Availability Survey map was created by drawing together zoning maps held by each local authority in the State.
Developed by the Department of the Environment, it sets out individual plots of land in towns, villages, cities and rural areas, and indicates the number of homes permitted on each site.
It took almost two years to develop, and provides planners and developers with an overview of the available land for housing.
It does not include land zoned for mixed-use development, which would generally include some housing provision. Nor does it include derelict sites.
The data is based on the situation as of March 31 last. Stage 1 land is considered not viable for development in the short-term because necessary services such as water are not in place. Stage 2 land has no major constraints. Not all the land has planning permission.
