Group 27: Airbnb's Impact on Affordable Housing in New York
Overview | Proposal | Poster | Application | Report |
ABSTRACT
Community groups and housing advocates in cities across the world have begun to sound the alarm about the impact Airbnb is having on affordable housing in their communities, citing concerns about housing supply lost, racialized gentrification, and impact on residents’ quality of life. Airbnb’s business model has been particularly controversial because it so clearly flouts existing housing and land-use regulations in many or even most of the cities in which it operates, and does so in a fashion which appears to undermine policies aimed at protecting the supply of affordable housing. Airbnb and its advocates insist that these regulations must be updated to accommodate the new possibilities presented by the sharing economy. Opponents argue that Airbnb aims to avoid regulation and taxation, and threatens affordable housing in cities.
We chose New York, a typical Airbnb city, as an entry point to understand Airbnb’s impact on housing. We aim at presents a comprehensive visual analysis of three years from 2015 to 2017 of Airbnb activity in New York City. It relies on the most comprehensive third-party dataset of Airbnb activity available, and methodologies of visualize and analysis geographical data.
Our report is motivated by the concerns increasingly raised by local communities and housing advocates that short-term rentals are clearly affect traditional residential rental housing and hotel accommodation. Either concern, if justified, would represent a serious problem for municipal authorities. But reliable, up-to-date evidence has been hard to come by. Accordingly, we want to explore the Airbnb activity in New York City, analysis different neighborhood’s distinct characteristics by Geospatial pattern analysis, including significant seasonal tourism distributions, ethnic composition, price and density differences. Meanwhile, we set out to discover the impact on housing market, which leads to lower affordability housing, housing supply lost.

OBJECTIVES
Airbnb Geospatial Pattern Analysis:
- Using geospatial analysis tools to map out the Airbnb property distribution in New York City across 5 boroughs from Year 2015 to 2017. We intend to visualize the sprawling pattern in New York City and dynamically changing density of listing Airbnb property in each neighbourhood.
- To refine the given broad geographic pattern, we turn to investigate the revenue-earning patterns in multiple neighbourhood derived from listing price and transaction records. The Airbnb revenue patterns would be compared with the gross rent income records across neighbourhood, which unveils the geographical rental gaps under two different “renting”form – Normal and Airbnb-ed.
Airbnb's Impact on Local Housing Market:
After exploring the Airbnb activity in New York City, we tend to discover the impact on housing market, which leads to lower affordability housing, housing supply lost.
- We would line up the historical housing stocks in rental market and Airbnb property listing stock to simulate a group of shifting stock in two markets. In this way, we intend to estimate that how much of housing is removed from the rental market to become Airbnb-ed. Additionally, we supplement with the vacancy units comparison across years to further justify our inference. Besides, the room type will be included to get further information as well.
- By introducing above revenue patterns, we will find out the motivation behind “Airbnb-ed”prevalence in rapidly sprawl neighborhood. We will set a threshold based on availability across a year to calssified host into “Professional”and “Part-time” to reveal which types of room owned by which type of host tends to achieve premium rental benefited from Airbnb.
- Citing the concerns about illegal renting, which is fewer than 30 days short term rental. We will take a look at the Airbnb activity during tourist season (e.g Summertime, Christmas & New Year) especially by comparing the Airbnb listing changes and availability during tourist season and normal time.Then we will generate the revenue patterns for those property which only extremely activates during tourist season to assess the potential short term rental benefits leveraged by Airbnb. Meanwhile we will also highlight the number and ratio of illegal property during tourist season and the revenue made by these listings across different neighbourhood and multiple room types to sound the alarm of housing regulation.
