Much of the coverage concerning the preliminary Census release from yesterday has focused on vacancy. This has meant distinguishing between those housing units classed as holidays homes in each area and units that are ordinarily vacant. One of the more puzzling statistics to emerge from this distinction is the 190% increase in the number of holiday homes in Dublin city since 2011. In that year, there were 322 vacant holiday houses in the city but those rose dramatically to 937 in April’s census.

What might account for this near trebling in five years? In particular why, in the middle of a housing shortage, is there almost twice as many housing units classed as holiday homes in a dense urban area when compared with five years previously? Speculation with some others on twitter concentrated on the possibility of these being AirBnB properties. I decided to put some focus on this explanation to see if there’s any truth to it.

In recent months there has been a number of online features concerned with how AirBnB (a company which matches bodies with beds across the world) might be affecting rents. If people are renting their city property through AirBnB for much of the year, how might this affect people seeking to live and work in the city full time? For example, in a number of North American cities there are concerns that full-time AirBnB rentals are displacing residents (e.g. see here or here) who are in lower paid jobs and subject to ever-increasing rents. Some city authorities are coming under pressure to restrict the use of full-time rentals through the company. A property owner can make far more renting out short term lets to passers-by than s/he can from locals who are seeking merely to continue living in a city they work and have a life in.

There is a vital politics to this displacement where AirBnB rentals are pricing people of lesser means out of particular areas of a city bustling with tourists. It is an extreme example of gentrification by displacement, almost making the popular term redundant in its bluntness. The uneven geographies of AirBnB rentals hits home for many in this city too.

In Dublin in June, the city council raised the prospect that full-time AirBnB rentals in Temple Bar, a particular zone of intense tourist activity, would be subject to planning permission. The Council argued that a particular property in the neighbourhood was effectively a material change of use from residential to commercial. It insisted of course that this ruling was “site specific” and did not cover the entire Temple Bar area. The prospect of an imposition of a change of use for the area as a whole is remote though: this seemed like a shot across the bow.

Luckily for us, InsideAirBnB allows us all access to data for rentals across a large number of cities to determine if the company is facilitating displacement. I took the January 2016 data from this site and, aside from knowing the first names of each of the renters, the database contains a number of interesting data.

There are 3,772 properties in the AirBnB database in the four local authority areas. Of this number, 3,116 (83%) are in the Dublin City Council area. 1,222 or 39% of this subtotal are for rent, according to the dataset available under Creative Commons, for 300 days or more per year. The heatmap below (Map 1) shows that near-year long rentals are broadly clustered within the Temple Bar, Cow’s Lane and north Docklands areas. Those rented 365 days per year (249 properties) are distributed slightly differently. They are by no means overlooking the splendour of Dublin Bay.

They are scattered across the city with some clusters in Drumcondra, Rathmines and Portobello. Map 2 below shows the distribution of these year-long AirBnB properties across the Dublin City area, Map 3 shows the distribution of entire house/apt available for rent for 300 plus days a year (as opposed to a room in an already occupied dwelling).  It is not beyond the realm of possibility therefore that the >300 days per annum rentals in this database includes a figure of 937 holiday houses recorded in the census. In fact, there are 934 properties rented out for 335 days or more per annum in the database. If you spent the month of December in your own city centre apartment, and rented it out for the remaining 335 days of the year, you might well be among the 937 recorded in the Census.

But this is a numbers game. We’ll have a better sense of the distribution of the city’s holidays homes when the more extensive data release begins in April 2017.
