Presented by What Works Cities and Bloomberg Made with love by: Xiaomin Wei, Joey Hu, Armin Burgmeier, Luke Babich and Nick Madrid.
Housing inequality is present in cities across the United States, rendering low income families unable to obtain affordable housing. Lack of fair housing opportunities is just one of the problems communities face: many people also lack access to transportation and services within the community.
Help cities enhance their use of data and evidence to uncover new ways to revitalize neighborhoods and improve the lives of residents.
The Housing Inventory is the Planning Department's annual survey of housing production trends in San Francisco. It has reported changes in the City's housing stock, including housing construction, demolition, and alterations, since 1967.
The Housing Inventory also reports the annual net gain in housing units citywide by general Zoning Districts and by Planning Districts. Net gain is the number of newly constructed units with CFCs issued, adjusted for alterations - which can add or subtract units - and demolitions. Affordable housing, condominiums, and changes in the residential hotel stock are other areas of interest covered by the Housing Inventory.
| Address | Units | Net Units | Affordable Housing | Affordable Target| | —————— |:—–:|:———:|:——————:|——————| | 1407 Market Street | 317 | 317 | 38 | LI - Low Income |
We took the address provided in the Housing Inventory data sets and used the Google Map API to gather associated lattitude and longitude for each value.
We then leveraged the recently open sourced Jupyter Notebook widget for leaflet maps to plot the net change in units for a given address.
Green
= units were added. Dark Green
= larger number of units added.
Red
= units were removed. Dark Red
= larger number of units removed.
The data show an increase in construction activity in each year from 2011 to 2014
We then took that same data for a given year (buildings where units were added/removed) and searched Zillow for current rents. Data was normalzied by price per square foot.
Bright Red
= units that are the most expensive (on a price per square foot basis)
Black
= units that are the least expensive
parking
topic area for buildings found in the Housing Inventory from 2011-2014 that also had an article(s) on SocketSite.It's important to know that any building built before June 13, 1979 is required to adhere to San Francisco's rent control laws.
Significant work was done to gather buliding information such as year built and assessed value from the San Francisco Property Information Map.
We took a random sampling of San Francicos's 200,000+ buildings and plotted over 1,700 buildings with color indicating the year they were built. While not comprehensive, it is a representative sample.
Dark Green
= older building
Overlay Petitions to Rent Board to see if there are specific areas of San Francisco receiving a larger number of reports (either from tenants or landlords)
Explore any correlation between Airbnb listings and changes in inflation/rents as well as eviction notices.
